The oldest plant DNA on record say the planet was far warmer hundreds of thousands of years ago than is generally believed. What does this say about the problems of global warming?
PLEASE don’t give the USA any evidence to reinforce their ostrich with its head in the sand attitude to this issue. Whether or not global warming is a natural, cyclical phenomenon there is absolutely no doubt that humanity is exacerbating the problem and we need to do all that we can to slow it down.
