网上看到的。 具体请看：http://www.metoffice.gov.uk/corp ... ce/myths/index.html Climate change myths Prof. John Mitchell OBE FRS, Chief Scientist at the Met Office explores some of the common myths about climate change. The Met Office recognises that climate change is a complex subject. There are genuine areas of uncertainty and scientific controversy. There are also a number of misunderstandings and myths which are recycled, often by non-climate scientists, and portrayed as scientific fact. Recent coverage has questioned the influence of humans on the climate. While the arguments used might have been regarded as genuine areas of sceptical enquiry 20 years ago, further observed warming and advances in climate science render these out of touch. Myth 1 - Ice core records show that changes in temperature drive changes in carbon dioxide, and it is not carbon dioxide that is driving the current warming Myth 2 - Solar activity is the main driver of climate change Myth 3 - There is less warming in the upper atmosphere than at the surface which disproves human-induced warming Myth 4 - The intensity of cosmic rays changes climate Myth 5 - Climate models are too complex and uncertain to provide useful projections of climate change Myth 6 - 1998 was the warmest year in the global annual temperature record and this has led some to claim that temperatures have been decreasing ever since.
