"The science is particularly complex because the ozone hole
continues to affect the region's climate in ways that aren't well
understood. And global circulation of winds and currents remains a
challenge for scientists to grasp.
"One record warm temperature doesn't cut through all that complexity," says Schmidt. (Learn about the recent cold snap in the U.S.)
When it comes to the whole planet, the Earth remains on track to warm
by an average of at least two degrees C (3.6 degrees F) by the end of
the century, scientists report,
although precisely how much is expected to depend on countries'
abilities to reduce emissions of heat-trapping greenhouse gases."the point is that, for example, while we had record cold in some eastern areas of the us this winter, there were records being set in the western areas for dryness and warmer temperatures. it is a hugely complex model with large numbers of variables which in turn affect other variables. at the base of it all is the agreement by 97 per cent of climate scientists that the climate change is real and the impetus to try to alter that before we reach a tipping point and will alter our world in ways which are detrimental to life itself by changing the climate to the extent that it alters the food supply and fresh water resources 4951
