Chart of the Day

The latest MIT study of global warming has now been published in the Journal of Climate, and its conclusions are grim.  The chart on the right shows their new projections (in red) compared to previous projections (in blue).  (The heavy lines are the median projections; the lighter lines are the 5% and 95% percentiles.) In the middle latitudes, they project warming of nearly 5ºC compared to previous projections of about 2ºC.  At the poles, they project warming of 8-10ºC compared to 5-6ºC.

Why the change?  Joe Romm summarizes the technical explanation: “The carbon sinks are saturating, and the amplifying feedbacks are worse than previously thought.”

Is Waxman-Markey enough to stop this?  Not even close.  Will anything we do make a difference if we don’t get the rest of the world on board?  Nope.  Does that mean we should give up?  Or continue wanking away on cost-benefit studies that still assume a 2ºC rise over the next century?  Or join the GOP buffoon caucus in pretending that CO2 is harmless because otherwise they wouldn’t put it in Coca-Cola?  No, no, and no.  It means we have to work even harder to strengthen Waxman-Markey and then press the rest of the world to follow suit.  The time for wanking is way past over.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
