Decide to have a positive day

By Judy Hooymeier

Our inner critic is the internal voice of negative judgmental self talk. It is the nagging feeling, the inner voice that makes us critical of ourselves and others.

We learn to be critical of ourselves as we learn to march to the drummer of others wants and needs, we learn to be critical of others when they do not conform to what we want or expect.

The inner critic speaks loudly in judgment of ourselves and others. It is a voice that yearns to castigate. It is the voice of enslavement to our egos and to the wants of others.

Sometimes our inner critic will leave us with feelings of self doubt; sometimes it will allow us to feel negative and critical of others. When we listen to our inner critic, we listen to negativity that separates us from our best self and others.

Our best personal and professional selves come from a place of self love and acceptance. When we can truly love and accept ourselves we can also see those in our world as collaborators on our path of personal learning. Love is a path which brings us closer to the seed of creation and to a place where we can grow, learn and to share joy with others.

We are all partners on a human journey, and the greatest challenge in our roadmap to personal and professional success is to cleave to our humanity, to the values of sharing and caring that make us brothers and sisters on the road of life.

Take a day this week to stomp out the voice of your inner critic; to free yourself from self imposed negativity and judgment.

Silence all criticism and negativity for 24 hours. Concentrate only on the good in yourself and in others that you meet and interact with. Give the inner critic a day off, and in so doing spend a day with your highest, greatest and best self.

 

Literary summary critique for, “Babylon’s Ark: The Incredible Wartime Rescue of the Baghdad Zoo,” by Lawrence Anthony and Graham Spence

By Jeff Kidd

Babylon’s Ark is the incredible true story of South African Conservationist Lawrence Anthony’s work to save the Baghdad Zoo, and the animals who lived there during the Iraq War. Anthony outlines his adventures and efforts in several phases in the book.

The first phase takes place on the Kuwaiti-Iraq border. Lawrence Anthony entered Iraq with two Kuwaiti Zoologists (Husham and Abdullah Latif) who were both from the Kuwaiti Zoo. The journey from the Kuwaiti border to the Baghdad Zoo was a ten hour trip (in their Toyota rental car) without a military escort or defensive weapons. Mr. Anthony and his Kuwaiti counterparts took precautions to avoid any elements of Saddam’s army, and the fedayees gangs who were fanatically loyal to the overthrown dictator. To get to the Baghdad Zoo they first had to enter the Al Zawra Park which is located in the center of the war torn city. Even after the Iraqi War had officially ended, fire-fights were raging against the Ba’athist terrorists who were loyal to Saddam Hussein.

The first military officer who provided an escort to the Baghdad Zoo was 1st Lieutenant Szydlik. Upon Lawrence’s arrival he discovered that the zoo had been badly damaged during the war. Most of the damage to the zoo was caused by looters. The looters stole vital zoo equipment. In addition, they also killed any of the zoo animals that they thought were edible. Lieutenant Szydlik introduced Mr. Anthony to Husham Hussan who was the Deputy Director of the Baghdad Zoo. Initially the zoo was in horrendous conditions. The cages were damaged, and had not been cleaned for months. Furthermore, the animals were severely dehydrated, and dying of hunger. To make matters worse, the animals were also suffering from the traumatic effects of the bombing war. The biggest problem the animal’s had was getting water. The looters had stolen parts of the zoo’s generator. The generator was essential to operating the water pumps; therefore the zoo staff had to manually carry water buckets from the canal which was located adjacent to the zoo. Lawrence Anthony may have been depressed, and discouraged at times but he remained steadfast by never losing hope of  rescuing the Baghdad Zoo.

In his own words,” Here in Iraq, we would make a stand that would send a message to fellow human beings: that you don’t do this to other creatures. For the most part the zoo’s animals were killed by looters and soldiers. The zoo staff reiterated that they needed their jobs; their families were as hungry as the animals.”

Lawrence got the Iraqi zoo staff to focus on the following elements: food, water, care, nurture. He also instilled the following strategy to save the zoo: (1) feed the staff, (2) attain buckets to hand-carry water from the canal, and (3) fix the pumps as soon as possible. The first hurdle in this three part plan was the pumps. Husham informed Mr. Anthony that he needed batteries, and a dynamo for his generator to make the pumps operational. Next,Lawrence tackled the issue of  feeding the zoo animals. He ordered the zoo staff to buy or barter for donkeys. Once the donkeys were acquired  , they were slaughtered and utilized as food for the zoo animals.

Before the United States invasion of Iraq most Iraqi’s were on government subsidized food aid. Saddam used his food aid policy to make the people dependent on him. Looting resulted after the war errupted; this in turn caused the collapse of law and order. Through (U.S. Army) Captain William Sumner of the 354th Civil Affairs Brigade, the Bagdad Zoo had attained an accredited representative in the bureaucracy. A man with sergeant stripes loaned Lawrence two spare batteries for use in the water pump at the zoo. During one of Husham’s trips downtown he discovered, and purchased a dynamo for the generator. The pumps were now operational, and spraying water everywhere.

To obtain a professional position during the reign of Saddam Hussein a person had to be a member of the Ba’athist Party. Husham was arrested , and relieved of his duties due to his past affiliation with the Ba’athist Party. Lawrence Anthony continued to fight to restore the zoo. Anthony’s ultimate triumph occurred when Captain Sumner got the coalition forces to act on his proposal to restore the zoo with a tentative budget of  $250,000.

In addition to the zoo animals, Anthony worked to rescue the Hussein family’s collection of exotic animals. Dr. Barbra Mass, the chief executive of Care for the Wild International-(CWI) stirred up a controversy by announcing to the media that she planned on relocating the Hussein family lions to South Africa. Her unilateral decision angered the Iraqi government. The lions, and the zoo animals were eventually prohibited from leaving. The animals were after all the property of the Iraqi people.

In conclusion, Lawrence Anthony was successful at saving the Baghdad Zoo, since he was able to motivate, and lead the zoo staff in sustaining, and improving the animal’s health. In a nutshell, Lawrence Anthony was successful in his mission due to his perseverance, and his ability to: (1) Improvise, (2) Overcome, (3) Adapt at All Costs!

Climate change impact on lakes and rivers: What to expect, how to adapt.

By Luisa Cristini, PhD. University of Hawaii at Manoa.

We have learned what climate change is and how are future climate projections made. But what does this mean for water environments such like lakes and rivers? How will climate change impact those environments? And what can we do to react and adapt to the projected changes? The website of Ontario’s Ministry of Natural Resources has a comprehensive, well-explained, rich section on climate change and its consequences on lakes and rivers to help us understand, mitigate and adapt these fragile ecosystems.

We have seen that climate change is impacting the Earth’s water balance and could affect the availability of water for human use. Climate change could also mean more extreme weather events and water-related hazards, such as flooding, drought and poorer water quality. Also, rivers and lakes support many economically, recreationally, and socially important kinds of fish and other aquatic life. Changes in water quality and quantity due to climate change could have major impacts on these fish and the aquatic communities. Climate change-driven increases in water temperatures could make some rivers and lakes unsuitable for the fish that now live there. Higher lake temperatures could result in shifts from cold-water species (such as Trout), to cool- and warm- water species (such as Pike, Bass, and Carp). As a result, the distributions and population sizes of some fish species may undergo dramatic changes as they are replaced by more temperature tolerant species. In some cases, already threatened or endangered species may disappear completely.

The impacts of climate change will be felt throughout the food web because changes in the composition and availability of phytoplankton and zooplankton (the primary foods at the bottom of the food web) may favor some species over others. Eventually, this could lead to a rearrangement of the organisms making up aquatic communities in many rivers and streams. Furthermore, these types of changes may, in turn, make conditions more favorable for invasive species (such as Asian Carp, Round Goby, or Purple Loosetrife).

We can, however, adapt to the projected changes. Adaptation is defined as “actions by individuals or systems to avoid, withstand, or take advantage of current and projected climate changes and impacts. Adaptation decreases a system’s vulnerability, or increases its resilience to impacts.” (Pew Center on Global Climate Change, 2009). Managing natural resources using adaptive management principles involves learning about climate change vulnerabilities and risks to species and ecosystems, evaluating possible responses, implementing adaptation action, and revising choices with new learning over time. Acquiring new knowledge and experience includes monitoring the impacts of climate change and the effectiveness of adaptation measures. As well it requires seeking out new data, and scientific and local knowledge and perspectives.

Climate change adaptation actions include broad strategies and site-specific management actions seeking to reduce threats, enhance resilience of species and systems, engage people, and improve knowledge. Communities and agencies that take proactive steps to prepare for potential climate change impacts will be more resilient to change. We must engage people and focus on identifying the most important impacts and investing in adaptive capacity.

Climate change will exacerbate many existing vulnerabilities in natural ecosystems and species (e.g., vulnerability of certain organisms to pathogens), and will contribute significantly to cumulative effects (e.g., enhancing environmental degradation). Existing threats that interact negatively with climate change may be reduced through measures such as invasive species research, prevention, and education.

An ecosystem’s resilience in changing environmental conditions is determined by its biological and ecological resources, including diversity of species, genetic variability within species, and condition and connectivity with other ecosystems. Measures to reduce habitat fragmentation can ensure species’ access to critical habitats and can facilitate species’ ability to shift ranges as climatic conditions change. Measures to maintain genetic and species diversity in ecosystems can have a positive effect on adaptive capacity.

The United Nations Framework Convention on Climate Change (UNFCCC) recommends that the implementation of adaptation be integrated into national and international sustainable development priorities and suggests the following steps for effective implementation:

  1. enhancement of the scientific basis for decision-making;
  2. strengthening methods and tools for evaluating adaptation;
  3. education, training and public awareness about adaptation;
  4. individual and institutional capacity building;
  5. technology development and transfer; promotion of local coping strategies.
  6. appropriate legislation and regulatory frameworks; and,
  7. an adaptive planning process that covers different time-scales, levels (e.g. national, regional), and sectors.

Adaptation to climate change can also be an opportunity to generate valuable co-benefits, as the Intergovernmental Panel for Climate Change (IPCC) points out, such as environmental protection and energy security. The ability of a country to take advantage of this opportunity and, in general, to adapt to climate change – i.e. its adaptive capacity – depends upon its economic wealth, technology, information and skills, infrastructure, and political will and institutions.

No time to volunteer? Try these 10 ideas for short term low commitment volunteering.

By Rebecca Niblett

People are more and more busy these days and it can be hard to find time to volunteer.  Even harder is finding the time and energy to search out that perfect volunteer opportunity and location.  And then, there is the fear – what if I make a commitment to volunteer for an organization and then I get busy or something comes up and I can’t make it?

I struggle with these questions a lot, both personally as someone who wants to volunteer, and as a volunteer coordinator trying to recruit volunteers to help out at Gamiing.

But, working with volunteers, I have found some answers to these issues.  I wanted to share these answers to help others in the same position as me.  So this is my list of short term (like 5 to 15 minutes), one time, or low commitment volunteering ideas:

  1. Write a letter, article, or review of the organization online, for a local paper, a newsletter, or for the organization to post on their website testimonials page.  Letters to the editor or your local paper praising a service the organization offers, or an event they held could be helpful.  Or, find the organization on some of the many review/listing sites online and write a positive review.  Write an article about your trip or experience with the organization for your school paper or company newsletter.
  2. Take some photos or film of important stuff the organization has or does (like for Gamiing you could photograph the property and wildlife you see on it, or events that we have).  Post these photos online, on the organization’s social media sites, send them a link to the photo/video, email them photos or digital video files, or mail or drop off hard copies in person.
  3. Create a mini fundraiser for the organization with your family and friends.  This could be anything from a penny drive (collect the pennies from coworkers’ change), to providing a pot of homemade coffee rather than store bought and asking coworkers to donate the money they would have spent on coffee, to a penalty jar  (swear jar) where every time a family member breaks a rule (swears, drives instead of walks somewhere, eats something off their diet, buys lunch instead of packing their own…) they must put 10 or 25 cents in a jar, to asking people to give donations rather than gifts for your birthday.  Be creative and have fun with it!
  4. Content curration for social media.  This role is one where a longer term commitment might be helpful, but where the time commitment can be as small (or large) as you want it to be.  This is also something you can do while you are doing other tasks online.  A content curator picks a topic or two that they are interested in, that meshes well with the organization they are volunteering with.  Whenever they come across interesting content online (in blogs, newspapers, articles, other sites) they either post the link directly on the organizations social media sites (tweet it, post on facebook etc.) or send the links to someone at the organization in charge of social media content for their use. (Gamiing is looking for some content currators so if this appeals to you email me at volunteermangment@gamiing.org)
  5. Even shorter and with less commitment – tweeting, posting, talking about, and passing on information about an organization can be a huge help.  See that an organization is having a fundraising event that you think looks fun? Tweet about it to your friends, or phone someone who might be interested.  Pass on links to an organization’s website to friends with similar interests.  Encourage your friends to like their facebook page.  Replace your profile pic with the organization’s logo.   The organization may never know that you have done it, but trust me, they will be happy that you did.
  6. What about in person stuff?  Well at Gamiing for example we always need help with the nursery and grounds.  Can’t commit to a long term regular schedule of volunteering? Why not talk to the Volunteer Coordinator or someone on staff about little tasks you could do whenever you have time.  At Gamiing that might be weeding plants at the nursery on your way to hike on our trails.  Or, picking up litter, or fallen sticks from the trail to keep it clear while you hike.  Or report a problem with the trails or grounds to staff (such as a tree fallen across a trail).
  7. Another idea to help out an organization is to print out a few (like 1 to 10) posters or flyers (contact someone at the organization to get a digital file) and post them at your school, gym, church, club, rec centre, library, work place, or other places you frequent.  Gamiing has several posters that we would love to see posted around the local communities.
  8. If the organization doesn’t have a good poster or flyer why not offer to design it for them?  Gamiing can always use help with posters and flyers for upcoming events and our regular programs.
  9. Make something the organization can use (it’s a good idea to talk to them first about what you want to make).  Many organizations need to send a lot of thank you cards to donor and other people, why not have your kids help to make a set of thank you cards they could use?  Or, some organizations give out gifts or meals to people in need – why not decorate some bags for those gifts?  Artistic? Why not draw some images to use in colouring contests, or for kids to colour at programs/camps?
  10. Use a microvolunteering website like Sparked.com to find one time/low commitment volunteer opportunities.  There are lots of opportunities with lots of different organization to do everything from review a webpage, to design a logo, to draft a letter and more.

Gamiing and a lot of similar small not for profit organizations are in need of your help. But, you don’t have to give them a huge time commitment to be helpful.  Volunteering can be easy, fun, and fast!

One note of caution: don’t be surprised if you get hooked on volunteering and find that you are spending more time than you planned!

If you are interested in helping Gamiing with any of these or in another volunteer role check out the website or email me at volunteermanagement@gamiing.org.

Happy Volunteering!

March Break Fun!

By Rebecca Niblett

The world is mud-luscious and puddle-wonderful.
e. e. cummings

Gamiing follows a philosophy based on reconnecting people with the natural world.  We believe that our society is quickly losing our connection with other living things and the world around us.  This leads to problems like Nature Deficit Disorder (See Richard Louv – the author of “Last Child in the Woods” info on his website here: http://richardlouv.com/).

Thus, we decided that for March Break this year we would give families an opportunity to reconnect to the natural world at Gamiing.  We did this by providing a variety of fun, family directed activities for families and groups to do while hiking the trails at Gamiing.  Our hope was that by giving children and families activities that required paying attention to what was going on around them, without being too structured, they would be able to spend that time outdoors really connecting to what they saw around them.

The beautiful weather was (mostly) a bonus, as many groups came out to enjoy the warmth and sunshine.  It was not for the faint of heart though – slogging through the mud and puddles meant that a lot of families returned soaked and covered in mud from their adventures.  For most this just added to the fun.

One memorable family, with a dog and two young girls in tow returned from their sojourn in the woods laughing and soaked from head to toe.  The youngest girl, when sitting on the boardwalk outside the discovery shack lifted her leg, to allow the water to pour from her rubber boots. It was not until they were gone that I noticed the wood of the boardwalk was soaked where she had sat!

It may be a dry spring in the Kawarthas – but there is still lots of mud left at Gamiing for those brave folks willing to risk getting muddy in order to pursue adventure and connection with the natural world.

 

 

How do climate models work?

By Luisa Cristini, PhD. University of Hawaii at Manoa.

Generally speaking, a climate model is a mathematical representation of the climate system based on physical, biological and chemical principles, included in equations. In addition, climate models require some more inputs derived from observations or other studies.

Many climate models have been developed to perform future climate projections, i.e., to simulate and understand climate changes in response to the emission of greenhouse gases. Models can also be powerful tools to improve our knowledge of the most important characteristics of the climate system and of the causes of climate variations. Climatologists cannot perform experiments on the real climate system to identify the role of a particular process or to test a hypothesis. Thus, climate models are used to perform experiments in a virtual world.

For a climate model describing nearly all the components of the system, only a relatively small amount of data is required. For instance, the solar irradiance (the amount of solar radiation arriving at a specific spot at a specific time), the Earth’s radius and period of rotation, the land topography and bathymetry (the underwater “topography”) of the ocean, some properties of rocks and soils, etc. Data are also important during the development phase of the model, as they provide essential information on the properties of the system that is being modeled. In addition, large numbers of observations are needed to test the validity of the models in order to gain confidence in the conclusions derived from their results.

The models used for future global climate projections are called General Circulation Models (GCMs) and try to account for all the important properties of the system at the highest affordable resolution. The term GCM was introduced because the first goal of these models is to simulate realistically the three dimensional structure of winds and oceanic currents. They are classically divided into Atmospheric General Circulation Models (AGCMs) and Ocean General Circulation Models (OGCMs). For climate studies using interactive atmospheric and oceanic components, the acronyms AOGCM (Atmosphere Ocean General Circulation Model) and the broader CGCM (Coupled General Circulation Model) are generally chosen.

General circulation models provide the most precise and complex description of the climate system. They compute the values of model variables at a given time on a horizontal grid (across the surface of earth). These values provide enough information to reconstruct, over the whole domain (the area studied), an approximation of the corresponding field. Currently, the horizontal resolution of GCMs is typically on the order of 100 to 200 km. Also, nowadays, GCMs take more and more components into account, and many new models include sophisticated models of the sea ice, the carbon cycle, ice sheet dynamics and atmospheric chemistry. Because of the large number of processes included and their relatively high resolution, GCM simulations require a large amount of computer time. For instance, an experiment covering one century typically takes several weeks to run on the fastest computers.

The interactions between the various components of the system (atmosphere, ocean, sea ice, land surface, marine biogeochemistry, ice sheets) play a crucial role in the dynamics of climate. Some of the interactions are quite straightforward to compute from the models state variables, while more sophisticated parameterizations (decisions about variables to include) are required for others.

After their development, climate models have to be tested to assess their quality and evaluate their performance, especially with regards to the scientific objectives of the studies that will be conducted.

A first step is to ensure that the numerical model solves the equations of the physical model adequately. This procedure, often referred to as verification, deals with the numerical resolution of the equations in the model, but does not check the agreement between the model and reality. It makes sure that no coding errors have been introduced into the program and that the numerical methods used to solve the model equations are sufficiently accurate.

A second test for the climate model is the validation process, i.e. determining whether the model accurately represents reality. To do this, model results are compared with observations (e.g., temperature, precipitation, etc.) obtained in the same conditions and interpolated on the same grid.

Additionally, the model must be able to simulate reasonably well the climate in recent decades for which we have good estimates. This means performing simulations including the evolution of both natural and anthropogenic forcings over that period. In these simulations, the long-term average of various variables (such as temperature) in all the model components is compared with observations on given time slices. Furthermore, the ability of the model to reproduce the observed climate variability on all time scales is also checked.

A second test period for climate models is the Holocene (the geological epoch which began around 12,000 years ago and continues to the present) and the last millennium, for which we have a reasonably good knowledge of climate variations. Climate models have to be able to describe well enough the climate variations that happened in that time and for which we have data (inferred from tree rings, ice cores, historical data and other “paleoclimatic records”).

Since their invention, in the 1950s, GCMs have been further developed and there has been a lot of work and research behind them in each discipline connected to climate science (physics, chemistry, biology, mathematics, geology, hydrology and so on). Modern models are very accurate in the representation of the (Earth and) climate system and are now able to give us insights into both past climate changes and future climate projections.

Snow Golf Stories – Winterlude Feb 20, 2012

By Juanita Artrip (Gamiing Volunteer) & Rebecca Niblett

Winterlude this year was a big success. Despite the weather throughout the Winter, the day of Winterlude was perfect; sunny and warm, with a good accumulation of snow. We had a wonderful turnout and are looking forward to next year already.

Mom Robin and Collin DeShane, 2 play Snow Golf

Snow golf was one the many hands-on activities set up for kids to play during Winterlude 2012, and it was a big hit!  For those of you who do not know what snow golf is, it is a hybrid of miniature and regular golf, but it is played in the snow with brightly coloured golf balls so you can easily see where your ball lands. Our course this year was built by volunteers and included hills, obstacles, and tricky corners to navigate.

The snow makes it a little bit more challenging to hit a chip or straight shot, but fun and laughs were had by all while playing the nine-hole course.  For more pictures check out the gallery in the Lindsay Daily Post here.

One particularly funny and memorable moment was when a mom was explaining to her little boy how to play snow golf.  She told him to put the ball in the hole, and that’s exactly what he did–by picking up the ball in his hand, running as fast as he could to the hole and dropping it in!

And to that, we say well-played, and we look forward to seeing you on the snow golf course at the next Winterlude!

The Story of the Land Part 3: The Schipper family learns from the land and the creation of Pigeon Lake

By Mieke Schipper

As told to a grade two class visiting Gamiing Nature Centre

25 years ago

It is 25 years ago when our family came here to this farm to live. We called it “Paradise Farms”, because we thought it was beautiful.  However, the land was rather barren, that means unproductive ; not much was growing there, except rocks it seemed, like large pebbles and small rocks.

We walked the land every day and went into a different direction each day.  And we began to wonder.  What has happened here?  Who lived here?  What did they do?  We had so many questions and we really didn’t know where to get the answers.

And then, one day, I got it. I thought, the land is telling us something.  But how can I find out what it is the land is telling us?

What do you think? How can we find out what the land is telling us?

Listening, that is good. But is the land talking? Well, yes, but the land is NOT talking like you and I can talk and listen to one another.

I had to learn to listen another way, in a way my friend Nancy listens. She is deaf, but tells me she listens with her eyes and nose and hands and mouth and smell. That is how she finds out what it is I am talking to her about.

So, I had to learn to listen like Nancy is listening,
with my ears –listen to the sound of the wind, the birds, the rush of water;
with my eyes – what is growing here and why is that not growing anywhere else, what kind of animals are living here;
with my nose – the smell of flowers, trees and shrubs, the smell of animals,the smell of the lake, which changes with the season;
listening with my hands – feeling the different barks of trees, grabbing a hand of soil;
and with my mouth – tasting what the land is offering me, like berries, lots of berries, roots of plants and young leaves of dandelions.

So when I had finally figured that one out, I started to walk the land in a very different way.
Why was it so barren and rocky?

 If you look at this land, right here at GAMIING, you will see many leftovers of the years when people chopped the trees down and tried to farm.

Here, we are on top of a hill. Down there is the lake and the lake is in a valley. The top of the hill is on the west side and the lake down below is on the east side. Most of the winds that blow here come from the west and they blow toward the east. So when the trees were all cut and the grass had not grown yet, what do you think happened to the soil? Yes, that all blew down into the valley. That is what we call EROSION, the soil was wearing off the underlying rubble.

That is how I found the land. Now there are some trees and plants and shrubs that can live on and between rubble. Christmas trees are a good example. So, I thought that is probably what the land would like, getting dressed up again, not laying so naked there.

baby christmas tree

So we planted hundreds of Christmas trees, spruce and pine, but also hardwood like maple and ash and walnut. The roots of these trees kept the soil in place so it stopped blowing away and under the trees other plants and grasses started to grow, plants that would die down in the fall, then rotted and that became a little bit more soil. Also the wind and the sand rubbed the rocks and that became soil. So after many years, there became more soil of the rotted plants and the scoured rocks each year and the trees started growing and birds came to the trees and they carried seeds from other trees with them and dropped them in the field and that started to grow and the wind blew in seeds and they started to grow.

And in the soil there were still seeds from long ago and they started to sprout and grow. So very slowly we are getting a forest back.

And then the animals came. They found shelter on the edges of the new forests. There is now white tail deer, foxes, coyotes, wild turkeys, grouse, pheasants and many other birds.

And the land is so happy. It gives us so much back every day. But we still have to help the land a bit because sometimes there are trees and plants that are just like bullies. They come in and grow and they want to take over, but they don’t belong here. So we have to make sure that that is not going to happen. We like to keep the land happy.

Now I want to tell you a little bit about a lake that used to be a stream.

Just a minute ago I told you about the wind that blew the soil in the valley. I did not say that it blew in the lake, because there was not a lake yet.

On this old map you can see where Pigeon Lake was and then there was Pigeon River.
Pigeon River still exists but now starts further south, near Omemee.

When the dams in Bobcaygeon and Buckhorn were built, the government went to the farmers along the Pigeon River and told them that their land would be flooded. And that is what happened. So much land along the Pigeon River was flooded that it no longer was a stream but now had become a lake. But remember, the soil that had blown in the valley, well that is now the bottom of the lake, and things started to grow there, cattails mostly.

Lots of people hate cattails and marshes and wetlands and weeds in the lake. But actually if you listen very carefully, marshes and wetlands are the very best thing that can happen to a lake. They work like a coffee filter. The water goes through it but it holds dirty stuff back, like the coffee grinds in the filter. The marshes and wetlands are also home to many different kinds of birds and ducks and blue herons and ospreys and fish. And there are many flowers growing in the marshes. The marshes and wetland here at  Gamiing Nature Centre are called Victoria Wetland and they are special. They are an Area of Natural and Scientific interest, a mouth full. Just call them ANSI wetlands but remember that they are special!

So next time when you hear someone complaining about the weeds in the lake, especially about the marshes and wetlands you can tell them that these “weeds” are doing a bang-up cleaning job keeping our water healthy and they are home to many plants and birds and mammals and amphibians.

So, that is to story of the land. I hope when you go out that you can listen to the land and learn from it too.

My 30 Day vegan challenge – Week 4 (and day 30)

By Kirk Lilwall

“What the caterpillar calls the end the rest of the world calls a butterfly.”
~Lao Tzu~

 30 days have come and gone.  The whole idea of this challenge was to see if I could indeed make it 30 days without any dairy, fish, or eggs.  While I had been ‘vegetarian’ (technically lacto-ova pescatarian) for a while before embarking on this challenge, I had noticed that my reliance on those select animal proteins that I still consumed was becoming more and more prominent.  I ate so much fish you’d think I lived in a coastal town.

Looking back over my previous entries, I realize that I never really explained my background nor my reasons for wanting to try a vegan diet.  I was very much raised in a ‘meat and potatoes’ home and it wasn’t until a few years ago that I decided to switch to vegetarianism.  While I am an animal lover and an environmentalist, the reason for my switch was purely selfish.  I wanted to lose weight and I am afraid of eating my way to diabetes.

While I did lose some weight the results were limited by my love of junk food (especially sodey-pop.)  But there were other benefits in that I felt better and learned to cook new foods without relying on a piece of meat to be the centerpiece of the meal.

Now, why did I set out on this challenge?  I don’t fully know.  Again, I need to lose weight.  Also, my love of the natural world is strong (and the meat industry is undeniably a major contributor to climate change.)  My love of animals is stronger than ever, I suppose.  Did I do it to be contrary?  Difficult?  Different?

I’m honestly not sure why I did this challenge but I do know that I have enjoyed it.  I have lost a little weight, I sleep so much better than I did, I got to try some foods I may not have otherwise tried, and I just plain feel better.

With all of that said, I think this challenge may be shifting from 30 days to lifestyle change.  I’m a believer in possibilities (as in, nothing is impossible, only highly improbable a la Hitchhiker’s guide to the Galaxy) so I will not say that I will never knowingly eat animal protein again but I will say that I plan to continue along this vegan path as far as it will take me.  I hope that you’ll join me as I plan to continue these posts as I travel.

Climate change and future climate projections

By Luisa Cristini, PhD. University of Hawaii at Manoa.

The climate issue has become topical in the last years and the public opinion is fed with the most disparate and confusing explanations. Words like “climate change” and “future climate projections” have become popular, although, their meaning is not clear to many. Why does climate change? And how do climatologists know what the climate will be like in a hundred years?

What is climate?

To reply to these questions, it is important to first answer another question: What is climate? Climate is rather difficult to define because it involves factors from the smallest oceanic microorganism to the Earth’s astronomical configuration. Climate is not weather, though the two are often confused. The weather in a certain location is the state of the atmosphere at a particular time. This is characterized by physical parameters like temperature, precipitation, humidity, wind, pressure, etc. The statistics of weather over a time period of many years (at least 30, as defined by the World Meteorological Organization) is the climate of a specific location. However, the atmosphere, and therefore weather, is influenced by the other components of the Earth system, i.e, ocean, land surface, biosphere (animals and vegetation) and cryosphere (ice). Therefore the state of Earth’s climate also includes the conditions of those parts. All the Earth’s subsystems are connected with each other; hence a change in one of them has consequences for the others. It is easy now to understand the difficulties of predicting how climate can change in the future.

Natural changes in climate

Since the beginning of Earth’s history, climate has always been in constant evolution, due to natural forcing (natural changes). The ultimate source of natural climate change is Earth’s position with respect to the Sun. The solar radiation reaching the Earth’s surface is not evenly distributed in space and time, due to the movement of the planet. In particular the periodicity of the Earth’s three orbital parameters -eccentricity (how close the orbit is to a circle), obliquity (the degree Earth’s rotational axis is tilted from perpendicular to its orbital plane) and precession (the circular movement of Earth’s North-South rotational axis) – over hundreds of thousands of years gives rise to the glacial and interglacial eras. Climate can also change as a result of tectonic movements, i.e., the movements of Earth’s crust, which can lead to different oceanic regimes. Changes in the atmospheric composition can lead to increase or decrease of the air temperature, with consequences on glaciers and ice sheets or land biosphere, just to cite two examples.

Human-induced climate change

Since the Industrial Revolution, a couple of centuries ago, humans are also contributing to climate change mostly by the continuous burning of fossil fuel and the extensive use of land and ocean resources. The human impact on climate is called anthropogenic forcing. We know that the current climate change is human-induced because it’s extremely fast (on geological time scales!) and computer models cannot reproduce it without including anthropogenic forcing, in addition to natural forcing. According to the Intergovernmental Panel for Climate Change (IPCC), present and future climate change arises from the complex interaction between human and natural systems, socio-economic development and the associated emission of greenhouse gases.

Climate modeling

Future climate projections (not weather forecasts!) are produced with climate models on the basis of “emission scenarios”. Each scenario makes different assumptions about important factors such as how the world’s population may increase, what policies might be introduced to deal with climate change, how the global economy will develop and how much carbon dioxide and other greenhouse gases humans will pump into the atmosphere. The resulting projection of the future climate for each scenario, gives various possibilities for the temperature, but within a defined range.

Climate models are simply ways to quantify our understanding of climate. They are based on our understanding of basic scientific principles and climate processes and on observations. Obviously, they have limitations and will never be able to forecast the future exactly. However, over the last decades, climate models have become able to simulate physical, chemical and biological processes, and work on small spatial scales. Modern models are accurate in reproducing how climate works and have been able to reproduce the overall climate of the past. Additionally, models are tested and validated against many types of data. The results from climate modeling are robust (a variety of tests produce the same results) and have both theoretical and observational support. These results give us a reliable guide to the direction and magnitude of future climate change.
