Don’t Burn the Crops

Want a quick recipe for reducing Arctic ice melt fast? Stop burning northern hemisphere farmlands and pasturelands.

New research finds that large-scale agricultural burning in Russia, Kazakhstan, China, the US, Canada, and the Ukraine is melting Arctic ice.

The big contributor: Spring burning, when farmers torch crop residues and brush to clear new land for crops and livestock. The black carbon soot produced by these fires flows north, warms the surrounding air, and absorbs solar energy when it falls on ice and snow.

How bad is the problem? Springtime burning may account for 30 percent of Arctic warming to date.

The good news is there’s an easy fix. Targeting these burns gets us a genuinely fast reduction in temperature over the Arctic. Plus we know how to control these pollutants right now. Just stop burning. Right now. Before the melting ice rewires the oceanic currents delivering us the climate we’re used to.

The research is part of POLARCAT, an international effort to track the transport of pollutants into the Arctic from lower latitudes. Researchers were surprised to find 50 smoke plumes that analysis of satellite images revealed came from agricultural fires in Northern Kazakhstan and Southern Russia and from forest fires in Southern Siberia. The emissions from these fires far outweighed those from fossil fuels.

“These fires weren’t part of our standard predictions, they weren’t in our models,” says Daniel Jacob, a professor of atmospheric chemistry and environmental engineering at Harvard.

Although global warming is largely the result of excess accumulation of carbon dioxide, the Arctic is highly sensitive to short-lived pollutants like black carbon. Forest fires, agricultural burning, primitive cookstoves, and diesel fuel are the primary sources of black carbon.

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
