U.N. Report: Carbon Dioxide Levels at Record Highs

The concentration and the rate of carbon dioxide (CO2) levels in the atmosphere are spiking, according to new analysis from the World Meteorological Organization (WMO). Scientists believe the record levels are not only the result of emissions but also of plants and oceans’ inability to absorb the excess amounts of CO2. “We know without any doubt that our climate…

EPA Considering Lower Ozone Standard, Methane Strategy

In its Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards report—released Friday—the U.S. Environmental Protection Agency (EPA) suggests revising the health-based national ambient air quality standard for ozone. “Staff concludes that it is appropriate in this review to consider a revised primary [ozone] standard level within the range of 70 ppb [parts…

Wild at 50: The Wilderness Act Turns a Half-Century

By John Weaver

Recently, some neo-conservationists have argued that the Wilderness Act is facing a mid-life crisis, that somehow the notion of Wilderness is an anachronism in the ‘Anthropocene’ era of human domination of the planet. They argue that we should focus on domesticating landscapes to serve economic growth of the human juggernaut – rather than protecting remaining wild lands and preventing human-caused extinction of species. Other conservationists – myself included – disagree.

August 31, 2014: Diving Deep For Bioluminescence, Mixing Climate Change With Music and More

This week on National Geographic Weekend, join host Boyd Matson and his guests as they dodge whales and pirates on the Indian Ocean, track poachers in Africa, find lost societies in Orkney, shed light on glowing sharks, harmonize with melting ice in Antarctica, live underwater for 31 days, follow in the pawprints of a lone wolf for 1,200 miles, and rove across the red planet.

Obama May Use Executive Power to Forge International Climate Change Deal as U.N. Draft Report Paints Stark Climate Picture

A leaked draft of a report by the United Nations Intergovernmental Panel on Climate Change (IPCC) warns that global warming is already affecting all continents and that additional pollution from heat-trapping gases will worsen the situation. “Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the…

Who Will Save the Last Primary Forests on Earth?

By Brendan Mackey and James Watson

It’s now or never if the world’s surviving primary forests are to be saved. Will the international community act or continue to turn a blind eye to our planet’s key life support systems? Despite their shortcomings, international environmental agreements can provide incentives for national governments and land custodians to turn back the tide of forest destruction. Primary forests, however, remain invisible in forest policy debates and oddly off the radar for most conservation organizations.

Court Ruling Could Affect Nation’s Electric Grid

Editor’s Note: While Tim Profeta is on vacation, Jeremy Tarr, policy associate in the Climate and Energy Program at Duke’s Nicholas Institute for Environmental Policy Solutions, will author The Climate Post. Tim will post again August 28. A unanimous ruling by the U.S. Court of Appeals for the District of Columbia Circuit could change the way utilities and regulators consider electricity…

Yukon Expedition: The Forgotten Carbon Sink

Katherine Lininger and Micah Nelson are investigating how much carbon is stored in floodplains in the central Yukon River basin in interior Alaska. They and their colleagues just got back from spending five weeks in the beautiful and mysterious Yukon!

Through the Killing Field to See Walruses

To get relatively close to a trio of walruses on a beach at Kapp Lee on Edgeøya, the third largest island in Svalbard, we had to skirt a killing field littered with bones of the corpulent marine mammals. Preserved as a cultural relic, along with a couple of huts once used by trappers and researchers, the skeletons are a…

Report, Initiatives Aim to Take Action on Climate Change

Editor’s Note: While Tim Profeta is on vacation, Jeremy Tarr, policy associate in the Climate and Energy Program at Duke’s Nicholas Institute for Environmental Policy Solutions, will author The Climate Post. Tim will post again August 28. A new report from the White House Council of Economic Advisers finds that for each decade of delay, policy actions on climate…

Peru’s first-ever high-resolution carbon map could help the world breathe easier

To put an accurate price on carbon, you need to know how much you have and where it’s located, researchers say Stanford University scientists have produced the first-ever high-resolution carbon geography of Peru, a country whose tropical forests are among the world’s most vital in terms of mitigating the global impact of climate change. Released…

Expedition to the Land of Ice Bears

It was almost at the exact moment of the northern solstice that we boarded the National Geographic Explorer for a week-long expedition to the Arctic archipelago of Svalbard–the time of year when the sun reaches the highest point in the sky as seen from the North Pole. We were in the land of the midnight sun, and we would not see the darkness of night for the entire time we were there.

Rule for Regulating Existing Power Plants under Fire

U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy testified before the Senate Environment and Public Works Committee during a hearing on “EPA’s Proposed Carbon Pollution Standards for Existing Power Plants.” Debate about the proposed rule to regulate carbon emissions from existing power plants has swirled since the rule’s release last month. Coal-heavy states and others have criticized both the…

Climate Change Already Having Profound Impacts on Lakes in Europe

For perspective on how climate change is affecting lakes, those of us here in the U.S. can just look across the pond, where scientists and the agencies involved in meeting the European Union’s Water Framework Directive have amassed an impressive body of research on the topic. Not only are extreme weather events such as droughts…
