Thin Ice

Factors besides CO2 - Myles Allen and Wally Broecker

Myles and Wally explain how other factors in the climate system, such as dust particles, water vapour and clouds, can modify the effect on climate of rising levels of greenhouse gases - either decreasing or increasing the temperature rise. A consequence of this is that as dirty emissions from coal-fired power stations are cleaned up, the true greenhouse warming from our CO₂ emissions is being unmasked.
