Humans Are Responsible for Nearly All Modern Global Warming

No special reason for this post, but in case anyone ever suggests to you that, sure, global warming is real, but we don’t know how much is caused by humans—well, yes we do:

This is from the Fourth National Climate Assessment, which states with high confidence that “the likely contributions of natural forcing and internal variability to global temperature change over that period [1951-2010] are minor.” If you want to see all the human causes broken down further, here you go:

We humans have done things that both increase and decrease the amount of solar heat being trapped on the earth. However, they don’t balance out: the increases are far greater than the decreases. The result is global warming.

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
