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.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
