Climate Change

It's real. It's happening. It's accelerating. And it's our fault. Human activity — particularly the production of greenhouse gasses from fossil fuel emissions — is reshaping our planet, effecting rapid environmental change at a rate never seen before. Global temperature averages are creeping upward, seas are warming, rising and becoming more acidic, and extreme weather events such as droughts, wildfires, floods and powerful storms are more commonplace. Here's where you'll find the latest on the effects of climate change, and the measures that scientists, world leaders and innovators are taking to reduce our harmful impact on the planet and mitigate the damage already done.
