CO2 Maps Highlight Worst Offenders


A new, high-resolution, interactive map of US carbon dioxide emissions finds unexpected trouble spots. Too many emissions have been blamed on the northeastern US when the southeastern US is a much larger source than previously estimated. This according to Kevin Gurney at Purdue University, project leader. The maps and system, called Vulcan, show CO2 emissions at more than 100 times more detail than was available before. Previously, CO2 emissions data were reported, at best, monthly at a state level. Vulcan examines CO2 emissions hourly at local levels. Below is a great YouTube video of how it works, told in Geek, but probably understandable to nonGeek speakers or those with Geek as a Second Language. Look hard enough and you can almost find your own tailpipe in the maps.

The three-year project was funded by NASA and the U.S. Department of Energy under the North American Carbon Program, and involved researchers from Purdue University, Colorado State University and Lawrence Berkeley National Laboratory. Vulcan will revolutionize carbon cycle research. It’s considered the next generation in our understanding of fossil fuel emissions, with enormous implications for climate science, carbon trading and climate change mitigation work.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

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.
