Uncomfortable truth
Greenhouse gases raise Earth's surface Temp by between 20 and 30 °C, Royal Society figures
Some Green and other sources say greenhouse effect raises planet's temperature by 33°C
CO2 accounts for 3% of the Greenhouse effect, the major greenhouse gas is water vapour (95% of the effect)
Some Green sources say CO2 = 20% of greenhouse effect, water 60% (IPCC 1990 said 60-90%), other gases 20%
Anthropogenic CO2 is approximately 3% of the CO2 emitted annually, the rest is from natural sources
UK is responsible for 3% of World anthropogenic CO2 emissions
Air travel is 3%-6% of UK anthropogenic CO2 emmissions
So
Using non-Green data
25 °C Global warming effect of greenhouse gases
x 3% = 0.75000 °C Global warming effect of CO2
x 3% = 0.02250 °C Global warming effect of Anthropogenic CO2 emissions
x 3% = 0.00068 °C Global warming effect due to UK's Anthropogenic CO2 emissions
x 3% = 0.00002 °C Global warming effect due to UK's Air travel
Using Green biased data
33 °C Global warming effect of greenhouse gases
x 20% = 6.60000 °C Global warming effect of CO2
x 3% = 0.19800 °C Global warming effect of Anthropogenic CO2 emissions
x 3% = 0.00594 °C Global warming effect due to UK's Anthropogenic CO2 emissions
x 6% = 0.00036 °C Global warming effect due to UK's Air travel.
Can someone check the maths? I'm too busy looking for a cheap flight to somewhere with a sunny beach.
PS, it would still be a good thing if regional airports got more of the pie though, nobody wants to spend the best part of a day traveling down from Newcastle because all the international flights are from London.
