As predictable as it has been, it is discouraging to hear climate change denialists point to the massive amounts of ice and snow as evidence that “global warming” is imaginary. These are not folks who are conversant with science, so perhaps we should explain–very slowly and carefully–why global climate change, aka “global warming”–really is responsible for the bad weather.
As one climate scientist recently explained, there’s approximately four percent more water vapor in the atmosphere now than there was in the ’70s; that’s because the oceans and the air are warmer, and the added moisture in warmer air returns to earth as heavy rain and heavy snow.
This may not make sense to Glenn Beck or Sarah Palin, but most rational people can connect the dots, and understand why we need to limit carbon emissions. If we don’t, climate change will continue to cause extreme and unpredictable weather.
