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.

Far-reaching allegations about how a climate-sinning American multinational could shamelessly lie to the public about its wrongdoing mobilized a small group of New York students on a cold November morning. They stood in front of New York's Supreme Court last week to follow the unprecedented lawsuit against ExxonMobil.

Leah Garcés used to hate poultry farmers.
The animal rights activist, who opposes factory farming, had an adversarial relationship with chicken farmers until around five years ago, when she sat down to listen to one. She met a poultry farmer called Craig Watts in rural North Carolina and learned that the problems stemming from factory farming extended beyond animal cruelty.
Temperatures plunged rapidly across the U.S. this week and around 70 percent of the population is expected to experience temperatures around freezing Wednesday.
In April, he claimed they caused cancer, and he sued to stop an offshore wind farm that was scheduled to go up near land he had purchased for a golf course in Aberdeenshire in Scotland. He lost that fight, and now the Trump Organization has agreed to pay the Scottish government $290,000 to cover its legal fees, The Washington Post reported Tuesday.

This year, three studies showed that humor is useful for engaging the public about climate change. The studies, published in The Journal of Science Communication, Comedy Studies and Science Communication, added to the growing wave of scientists, entertainers and politicians who agree.
