Cards in this deck (23)
- 1Define 'weather'The short term behaviour of the atmosphere
- 2Define 'climate'The long term behaviour of the atmosphere in a specific area
- 3Name 3 internal factors affecting the climateVolcanoes
Surface Reflection
Changes in Atmospheric Gasses - 4Name 3 external factors affecting the climateSolar Output
Orbital Path
Tilt of Axis - 5How do volcanoes affect the climate?Short Term: Decrease temperature - ash blocks suns rays, and reflect them back into space. Mt. Pinatubo decreased global temperature b 0.4C
Long Term: Increased temperature as increase of carbon dioxide in atmosphere - 6How does surface reflection affect the climate?When there is lots of snow and ice, sunlight is reflected off back into space, causing a reduction in temperature
- 7How does a change in atmospheric gasses affect the climate?An increase of carbon dioxide, methane and any other greenhouse gas will increase the temperature. A reduction of these gasses will reduce the temperature.
- 8How does the sun's solar output affect the climate?The sun has a cycle of 10 years where there will be more or less sunspots - if there are more sunspots, it will be giving out more energy.
- 9How does the earth's orbital shape affect the climate?The path of the earth varies from elliptical to circular every 95,000 years. When it is circular, the temperature is more even, and when it is more elliptical, it is more extreme temperatures.
- 10How does the axis tilt affect the climate?The tilt varies every 41,000 years. The bigger the tilt, the more extreme the summers and winters are.
- 11What is the greenhouse effect?Heat energy from the sun passes through a blanket of Greenhouse gasses.
Some of that energy escapes back into space.
Energy that doesn't escape is reflected back to earth
Greenhouse gasses form a blanket, trapping the heat - 12Main causes of climate changeBurning fossil fuels
Methane production - 13Why is methane worse than carbon dioxide?Methane is 20x more potent than carbon dioxide
More is produced naturally - 14What is the Kyoto Protocol?Dec 1997
181 countries sign it to cut greenhouse gasses by 5.2% of 1990 levels globally.
National limits - most had reductions, some allowed increase (Iceland) - 15Why sign Kyoto Protocol?Next generation's planet
Look good to other countries - 16Did the Kyoto Protocol work?Not really:
US never fully agreed
Countries like India and China were still developing, so did have targets - now produce a lot of greenhouse gasses - 17What is the Bali Roadmap?December 2007
180 countries present to agree on initiatives to reach a secure climate future - 18Local Responses to Climate Change - Schools'Live Simply' campaign 2007
Encourage students to consider choices.
Schools introduce energy efficient water and heating systems from renewable sources - 19Local Responses to Climate Change - Local CouncilsSince April 2008, £4 million given to councils to cut energy usage.
Schemes include free energy saving lightbulbs - 20Local Responses to Climate Change - Local Interest Groups2005 - Manchester is my Planet
Pledge campaign to reduce carbon footprint and be involved with other green projects
Over 20,000 members - 21Positive Impacts of Climate ChangeExtended growing seasons
Can grow crops where previously couldn't
Scotland, Scandinavian countries - 22Negative Impacts of Climate ChangeRising sea levels
More extreme weather
Tropical diseases spreading (e.g. Malaria)
Loss of tourism industry (skiing)
Crop yield decreasing - 23Rising Sea LevelsThermal expansion
Melting ice caps
Threatens over 80 million people
If continue at current rate, rise 88 cm by 2100
Loss of land, flooding - lose homes, industry, even islands
