With the American South locked in a deep freeze, you can be sure that plenty of the folks suffering through the snow and ice storms are interpreting the big chill as more proof that global warming is a hoax. “Warming?” they scoff. “How can the planet be warming when it’s so darn cold?”
People in other parts of the world seem to have no great difficulty understanding the science but, in the good old USA where quite a few people consider science just another political opinion, it is going to take a lot longer to get most people to accept the cold facts about a warmer world.
Put very simply, here is what the predominant science says: Average global temperatures have been rising in recent decades. Some of the warming could be part of a natural cycle but, almost certainly, increased levels of CO2 in the atmosphere caused by the burning of fossil fuels are a pivotal factor in intensifying the phenomenon. The starkest evidence of the temperature jump is the rapid melting of the polar ice caps and the disappearance of the world’s glaciers.
