In physics there's the old law for every action there's a equal amount of reaction. Sometimes that's true in politics. If somebody's out there making nonsensical statements, but wielding power behind them a lot of people say, "Well, I need to react to that." Another reason for the increased prominence of the climate-change issue is the Paris Agreement itself. It's not a small thing when just about every nation in the entire world comes together and makes an historic agreement like this. It's a big deal. And the old cliché "The train is leaving the station" kind of applies.

Science is warning us that if we do not quickly reduce the global warming pollution that is trapping so much of the heat our planet normally radiates back out of the atmosphere, we are in danger of creating a permanent 'carbon summer'.

The Internet empowers individuals to play a more active role in the political process, as Obama's campaign has manifested.

I doubt nuclear power will play a much larger role than it does now.

Our new technologies, combined with our numbers, have made us, collectively, a force of nature

Any of us who work on the task of solving the climate crisis have at times an internal struggle between hope and despair. But that's one of the things that connects this climate movement to the previous great moral revolutions, like the civil rights movement and more recently the gay rights movement. So those who feel despair should be of good cheer, as the Bible says. Have faith, have hope. We are going to win this.

As it turns out, the scientific community has been addressing this particular question for some time now and they say that increased heavy snowfalls are completely consistent with what they have been predicting as a consequence of man-made global warming.
