Human Activity to Blame For 2003 Heatwave

Dirak writes "The temperatures of the summer of 2003 were almost undoubtedly the highest in Europe for over 500 years. New research shows how human influence, mainly fossil fuel burning, can be blamed for increasing the risk of such a heatwave and by the middle of this century every other summer could be even hotter than 2003."

The North Polar ice cap is floating on the sea. Therefore, the ocean level will stay exactly the same even if the whole lot melted. Try it yourself: half-fill a glass with water, add ice and mark the level. Observe how the level stays stubbornly constant as the ice melts.

The Sciencey Bit: 1 litre of water freezes to give 1kg. of ice. According to Archimedes' Principle, 1kg. of ice floating in water displaces 1kg. of water, which raises the level by as much as adding 1kg. of water -- in other words, 1 litre. Or, for the measurement-challenged: 1 pint of water freezes to give 1lb. 4oz. of ice. 1lb. 4oz. of ice floating in water displaces 1lb. 4oz. of water, which raises the level by as much as adding 1lb. 4oz. of water -- in other words, 1 pint.
