World Leaders Fail to Address Climate Crisis: Atmospheric Carbon Dioxide Measurements Exceed 400 PPM
Monitoring stations in the Arctic have confirmed atmospheric carbon dioxide measurements exceeding 400 parts per million (ppm), far past the acknowledged safe limit of 350 ppm.
Global levels of carbon dioxide—the most prevalent heat-trapping gas—are around 395 ppm, but Arctic levels signal where global trends are headed, and scientists are confident that levels will soon eclipse this ominous milestone worldwide.
According to the Washington Post, Jim Butler, the global monitoring director at the National Oceanic and Atmospheric Administration's Earth System Research Lab in Boulder, Colorado, said "The fact that it's 400 is significant. It's just a reminder to everybody that we haven't fixed this and we're still in trouble."
Preceding the Industrial Revolution, global levels of carbon dioxide were believed to be around 275 ppm. The meteoric rise in carbon pollution is mainly attributed to fossil fuel dependence, such as burning coal and oil for gasoline. Forest depletion and oceanic biodiversity loss complicate matters by diminishing nature's ability to absorb and repurpose carbon dioxide.
According to the Christian Science Monitor, former Vice President Al Gore wrote via email, "The news today, that some stations have measured concentrations above 400 ppm in the atmosphere, is further evidence that the world's political leaders—with a few honorable exceptions—are failing catastrophically to address the climate crisis. History will not understand or forgive them."
According to the Washington Post, Jerry Taylor, a senior fellow of the libertarian Cato Institute believes "political dynamics in the United States mean there's no possibility of significant restrictions on man-made greenhouse gases no matter what the levels are in the air."
The recent climate talks in Durban, South Africa left many feeling rightfully frustrated over our world leaders' lack of commitment to carbon reductions. With Rio+20 just around the corner (June 20-22), we'll see if recent actions such as 350.org's global "Connect the Dots" campaign have garnered the attention they deserve.

'This Will Be the Biggest Loss of Clean Water Protection the Country Has Ever Seen': Trump Finalizes Clean Water Rule Replacement
Today, the Trump administration will finalize its replacement for the Obama-era Waters of the United States (WOTUS) rule in a move that will strip protections from more than half of the nation's wetlands and allow landowners to dump pesticides into waterways, or build over wetlands, for the first time in decades.
Study: Native Americans Barely Impacted Landscape for 14,000 Years. Europeans Came and Changed Everything
There's a theory going around that Native Americans actively managed the land the lived on, using controlled burns to clear forests. It turns out that theory is wrong. New research shows that Native Americans barely altered the landscape at all. It was the Europeans who did that, as ZME Science reported.
