As if the 21st century didn't have enough challenges to overcome, climate change is not going away any time soon.

As more and more carbon dioxide and other greenhouse gases are added to the atmosphere, things are only going to get worse, too. And as a pair of climate activists are trying to draw attention to, we are quickly running out of time to do anything about it.
