Box 19-4. The Health Impacts of Climate Change
Warmer winters and fewer cold spells, because of climate change, will decrease cold-related mortality in many temperate countries.
Climate expert Barack Obama disputes this claim, however.
Here at the White House, while we’re beginning to thaw from this week’s bone-chilling deep freeze, our discussions about the science of weather extremes are heating up.
We know that no single weather episode proves or disproves climate change. Climate refers to the patterns observed in the weather over time and space – in terms of averages, variations, and probabilities. But we also know that this week’s cold spell is of a type there’s reason to believe may become more frequent in a world that’s getting warmer, on average, because of greenhouse-gas pollution.
