Transcript of Global Warming & Climate Change

Or else. & 10 indicators of a warming world Global temperature has increased over the years. Source NASA. Climate Change Global Warming By: D'angelo & Shahal CIVICS: Global Citizenship Climate change could include Industrial pollution Precipitation Weather Change Extreme Wind Global Warming — Increase if average temperature on Earth.

Climate Change — Changes in regional climate characteristics, including temperature, humidity, rainfall, wind, and severe weather events.
They are not the same. So what is Global Warming and Climate Change? 1. Sun's energy heats the earth
2. After heating, Earth radiates it back to space
3. Some greenhouse gases, water vapor, carbon dioxide, and other gases trap some of the outgoing energy and the heat is stored inside Earth. The Earth becomes hotter.
We need green house gases to maintain maintain a stable temperature but if the greenhouse effect becomes stronger than, it earth will become less inhabitable for living things.
The greenhouse gas content of the atmosphere is being altered by human activity. The result of this change is global warming. The Greenhouse effect Some of the extreme weather events
Brazilian drought
Pakistani flood
Chinese drought
Hurricane Sandy
Montreal flood Even just a 2°C increase can have impacts around the world to biodiversity, agriculture, the oceans etc Developing countries will be affected the most.
This is because:
lack of resources to cope
immense poverty
poor infrastructure Increasing greenhouse gases trap more heat Question 4:

Things we can do in our community to stop global warming:
- Ride your bike
- Use less heat and air conditioning
- Reduce, Reuse, Recycle
- Turn off lights that are not in use
- Buy energy efficient products
- Use less hot water
- Carpool
- Encourage others to conserve

How you can get informed!

- Join the Environmental Club at school

-You can:
• Learn more about our environment
• Participate in the EC activities
• Help spread awareness of how to prevent global warming Question 2:

United Nations work:

- United Nations Framework Convention on Climate Change (UNFCCC)
• International environmental treaty
• Objective is to stabilize greenhouse gas concentrations in the atmosphere to get it to a level that will prevent dangerous interference with the climate system
- United Nations Environment Programme (UNEP)
• Have an organization called Intergovernmental Panel on Climate Change (IPCC)
• Review and asses recent scientific, technical, and socio-economic information
• 195 countries work with IPCC

NGO work:
- Climate Solutions
• Educate the public
• Have local and regional groups
• Look to speed up practical and affordable solutions to prevent global warming Global warming is happening all over the world, hence the name global warming. Although, some areas (like the north and south poles) are affected more severely and more noticeably. Where When Why How The concentration of greenhouse gases in the atmosphere has increased largely due to human activities and the changes in the climate has been speeded up by human activities. Human influences by GHGs. Natural causes There are a number of natural factors responsible for climate change. Main ones are continental drift, volcanoes, ocean currents and the earth's tilt Volcanoes When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Human influences Nuclear factories emits water vapour. Spread of diseases
Warmer waters and more hurricanes
Increased probability and intensity of droughts and heat waves
Economic consequences
Polar ice caps melting
More floods
Fires and wildfires
Destructive storms
Death by smog
Cold Waves
Increased volcanic activity
More dangerous thunderstorms
Migration, conflict and wars
More outbreaks of deadly diseases
Loss of biodiversity and animal extinction
Death of ocean life
Ozone layer depletion
Diminished food and water supplies
Extreme weather patterns
Super storms
Ecosystem impacts
Rising sea levels
Increasing ocean acidification
Increase in pests and disease
Increase in world hunger
Agriculture are already being affected Few places where climate change will affect the most:
Bangladesh (floods)
Sudan (drought) North african countries
Caribbean (hurricanes)
Australia (forest fires)
Siberia (melting of ice)
Tuvalu (rising of sea levels)
Great Barrier Reef (rising ocean temperatures)
Alps (warmer temperatures- ice melting)
Britain (floods and storms)
Antarctica (ice melting)
Countries in Arctic (ice melting) Breathing
Burning fossil fuels (coal, cars, trains, electricity, furnace)
Using excessive amounts of cigarettes, cigars, marijuana, etc.
Production of cement
Forest fires
Deforestation ( trees absorbs CO2 and emits O2)
Aerosols — chlorofluorocarbons (CFCs) rice cultivation,
cattle and sheep ranching
decaying material in landfills.
coal mining
oil drilling
leaky gas pipelines cars
fossil fuels used for heat and electricity Since the industrial revolution began, due to human influences, climate change has increased significantly. The Issue Carbon Dioxide The cause of climate change could be divided into two simple groups. Natural causes and Human influences. Major human influence
Fossil fuel
Cement manufacture
Land use
Livestock http://climate.nasa.gov/interactives/climate_time_machine http://climate.nasa.gov/ Canadian Governments role Water Vapour Methane Nitrous oxide Effects (who) Who is affected the most by global warming?
Communities that that rely on farming
Children in developing countries
Poor people in developing nations who are facing barriers from expensive food (malnutrition) and clean drinking water Reduce, reuse and recycle
Use Less Heat and Air Conditioning
Replace your Light Bulb with energy efficient fluorescent ones
Drive Less and Drive Smart
Buy Energy-Efficient Products
Use Less Hot Water
Use the "Off" Switch
Plant a Tree
Encourage Others to Conserve
Use less electricity
Buy minimal packaged goods
Ride a bike
Use green electricity
Use renewable energy
Eat organic and locally grown food
Fly less
Get informed, involved and donate to organizations that work hard on solutions on climate change. There is no place like home... and there may never be again. Do your part. Produce more fuel-efficient vehicles
Improve energy-efficiency in buildings
Develop carbon capture and storage processes
Increase solar power
Decrease deforestation/plant forests
Improve soil carbon management strategies Few solutions for the industries and government: Individual Actions Things that the Canadian government is doing
Canada takes part in the United Nations Framework Convention on Climate Change
The government regulates Canada's Greenhouse Gas Emissions
Taken steps towards developing cleaner and renewable electricity grid
Committed $3 billion in funding for Carbon capture and storage (CCS)
Founding member of Global Research Alliance on Agricultural Greenhouse Gases (invested $19.6 million)
The government's goal for Canada is to reduce our total greenhouse gas emissions by 17 per cent from 2005 levels by 2020 (already reached half of the goal today) 2 Things that show the Canadian government is not enough to combat climate change
Pulling out of Kyoto Protocol
Alberta Oil sands

Kyoto Protocol, which is an international environmental treaty to reduce co2 emissions. Backing out of the protocol saved us $14 billion because we went over the limits of co2 emissions
Alberta oil sands is the largest source of CO2 emission in Canada and the mining of oil is destroying the surroundings. I think the government of Canada should do more because being a government of a first world country, they should be a role model and an expert in dealing with climate change and global warming.
