- Climate Change 2
- What gases make up our atmosphere?
- 21% oxygen, 0.03% carbon dioxide, 78% nitrogen, 0.07% water vapor and other gases.
- What are the greenhouse gases and their sources?
- Carbon dioxide - Burning fuels, Methane - animals (cows) and decomposition, Nitrous oxide - Engines, Halocarbons - Industry.
- Explain global warming:
- the gases in the atmosphere tray the suns heat rays causing the earth to heat up. Also called the greenhouse effect.
- What is the enhanced greenhouse effect? What thermal expansion?
- The greenhouse effect working more strongly. Thermal expansion - Sea levels rising as it warms up.
- What are the different air masses on the UK?
- Polar Maritime, Arctic maritime, Polar continental, tropical continental, Tropical maritime.
- What is the UK's climate likely to become?
- Hot and dry in the summer, and cold and wet with turbulent weather and flooding in the winter.
- What are maritime and continental climates?
- Maritime - near the sea, mild and wet, Continental, Dry and extreme.
- What was the stern review?
- Nicholas Stern wrote a report on Global Warming, that we should pay to reduce gas emissions to save paying later.
- What are the costs and benefits of the UK's climate changing?
- Benefits: heating costs change, less cold related illness, increased tourism, better agriculture, new wildlife.
- Costs: Droughts, heatstroke/sunburn, tarmac/rail lines, flooding, storms, flood barrier costs.
- What are the effects of climate change on Egypt?
- 99% of its people live on 5% of its land, because the Nile is the main water source. Climate change will cause Egypt to flood, and possibly water wars cutting off the Nile.
