Global Climate Change
The Roots of the Problem
What is Global Warming?
Global Climate Change, more commonly known as Global Warming, is a change in weather, heat and climate conditions across the globe. Since 1910, global temperatures have risen 0.8 degrees Celsius.
When one refers to “climate” it refers to the average weather conditions over the course of 30 years. In terms of 'Global' Climate it means the average climate around the world and its usual patterns and whether conditions.
Lets first define "Climate":
Why is the planet warming?
The greenhouse Effect:
The planet behaves somewhat like a greenhouse:
An increase in Greenhouse gases thickens the atmosphere so that the planet behaves somewhat like a greenhouse, trapping the heat inside and warming the earth.
Causes of Global Warming
Food Industries Impact on Global Warming
What increases Greenhouse Gases?
Humans are at the heart of the Problem:
-We burn fossil fuels which release CO2.
>by driving our cars
>by mowing our lawns
>by using boats and planes
-We use fossil fuels to make virtually all consumer product such as:
>Technology (eg. phones)
Climate Change is the Result of an Increase in Green house gases.
-We use electricity
Climate change is actually also caused naturally!
-Population increases
>more people using fossil fuels
>more people breathing
Volcanoes, for example, release huge amount of heat that gets trapped in our atmosphere!
What ARE Greenhouse Gases?
Fossil fuels are minerals such as coal, oil and natural gas.
4 main types of greenhouse gases:
Nitrous Oxide
Fluorinated Gases
The size of each piece of the pie represents the amount of warming that each gas is currently causing in the atmosphere as a result of emissions from people's activities.
The most famous of course is CO2.
-Cutting down trees and destroying soil and vegetation
- producing half a pound of hamburger=as much greenhouse gas as driving a 3,000-pound car nearly 10 miles.
The Agriculture industry is actually just as bad as burning fossil fuels with cars.
-food is the root cause for up to 30% of global climate altering greenhouse gases.
Billions of chickens, turkeys, pigs, and cows that are raised in the U.S. alone, produce enormous amounts of methane, during digestion and from the acres of cesspools filled with feces that they excrete.
Human Impacts
Environmental Impacts
Death rates are doing to increase exponentially.
The ill, young and old will suffer most as well as developing countries.
Currently Montreal's death rates are 70 due to heart disease per year. By 2020 this is expected to rise to 460.
-BAT, RODENT and INSECT populations will rise.
Disease Carrying plants will migrate north. (example)
Allergenic pollans grow more perfusively in warmer climates and with increased CO2 levels. Global warming will make these pollans as well as these disease carrying plants will thrive.
-More drought and floods
Air pollution kills 21 000 canadians a year meaning that 8% of all non-traumatic mortalities attribution air pollution.
With higher temperatures, Smog increases.
of climate change
Forgo Fossil Fuels
Start to build new infrastructure that produces less greenhouse gases.
As a community:
Put environmental sanctions on carbon Sinks
Invest in research
Start making more energy efficient Cars, stoves etc.
As Individuals:
Ride your bike to school or work.
Go Vegetarian!
Buy more efficient cars!
Switch to more fuel efficient energy sources.
Encourage the leaders of our country to lead us in a greener direction.
Be the Change You Want to See in the World
...at the same time
30% of agricultural land is used for livestock
Try to Go Organic and buy local as well.
-Tractors and farm equipments use a lot of fossil fuels to run.

-Fertilizers and pesticides are made from and using oil.

-Importing foods also uses a lot.

-Farming changes the land. It can result in desertification and soil erosion. -Trees and land destroyed to make room for agriculture hold carbon and take in carbon, when we cut them down, this is released.
Climate change increases water temperature which causes coral bleaching. By 2050, live corals could become rare in tropical and sub-tropical reefs due to the combined effects of warmer water and increased ocean acidity caused by more carbon dioxide in the atmosphere.

The loss of coral reefs will reduce habitats for many other sea creatures, and it will disrupt the food web that connects all the living things in the ocean.
Coastal Wetlands
Wetlands protect the shore from flooding, and they also provide important habitats for many types of plants and animals. As sea level rises, salt water could flood parts of the wetlands, leaving animals such as birds, alligators, turtles, and panthers with less habitat.
Warmer Climates=
Less cold places=
Less habitat for plants and animals that need to live in cold places.

If the Earth keeps getting warmer, up to one–fourth of all the plants and animals on Earth could become extinct within 100 years. Every plant and animal plays a role in the ecosystem, so losing one species can affect many others.
Loss of glacierss
As the temperatures increase, glaciers melt.
Coral Reefs
Glaciers reflect some of the suns rays so as they get smaller, The amount of sun they reflect also decreases. They also contribute to rising sea levels.
Actions Taken
-protests against governments
-campaigns to help stop climate change
-they educate people and governments through facebook, twitter and youtube. The best way to reach people is through the internet.
....is a world wide non-governmental, non=profit organization that has followers in almost every country in the world.
"We create opportunities for people to demand that governments take action on climate change."
Steps they Take:
1. Creating awareness of the climate crisis
2.Inspiring others, through the example own community based activism, to become empowered to take action in their own local communities.
3.Continuing to plan and carry out our own local/riding based actions to put direct pressure on government to act.
They developed what's called the "Kyoto Protocol". It sets standards for certain developed countries. It also helps developing countries with low levels of infrastructure and increasing populations to decrease their carbon foot print.

They get leaders, scientists and civilians to just TALK about solutions

December 2010= Cancun meeting where climate change discussions result in a package of decisions to help countries advance towards a low-emissions future.
Climate change is that it makes dry places dryer and wet places wetter.
Will we be able to feed our growing population?
What will happen if we can't?
Their Aim:
To stop global warming
How they Achieve this goal:
By both governmental and non governmental organizations!
Greenpeace: Global Warming
They send out petitions via email, phone and post
Posting inspirational and political videos.
UN=Governmental Organization
Unite world leaders to band together to do something about climate change!
Places like Miami, New Orleans and Venice will be effected.
We are losing topsoil ten times than it can regenerate itself...
Climate Change
Crops die
Less crop yields
Less FOOD.
Higher Food Prices
More people going hungry
Less seeds
More deaths caused by starvation
LESS CO2 Absorbed
25 million more children will be malnourished in 2050 due to the impact of climate change on global agriculture.
Bleaching of Coral Reefs
Loss of Habitat for Organisms
Disruption of Food Chain
Impact on fish we eat
More Natural disasters
What happens if the disaster impacts a nucelar power plant?
Soil erosion
waste lands
decreases the fraction of the earth we can farm
Less food planted
