Ozone Focus of EPA’s Latest Rulemaking

The U.S. Environmental Protection Agency (EPA) finalized a rule that sets domestic production consumption limits for hydrochlorofluorocarbons (HCFCs)—eventually phasing them out completely by 2020. The rule aims to reduce emissions from leakage and stockpiles of four HCFCs, a class of refrigerant linked to ozone depletion and climate change. “This rule finalizes allowed amounts of HCFC…

U.S., Military to Plan More Strategically for Climate Change

Climate change is a “threat multiplier” and worse than many of the challenges the U.S. military is already grappling with, according to a new report by the U.S. Department of Defense (DoD). The New York Times indicated that the report marks a departure from the DoD’s previous focus on preparing bases to adapt to climate…

Studies Focus on Warming of Oceans

Oceans absorb carbon dioxide and 90 percent of the heat caused by human activity—making their warming a critical topic for climate research. Two new studies—one on the upper oceans and one on deeper ocean depths—share findings about climate change’s effect on these water bodies. The first study, in the journal Nature Climate Change, provides the first estimate of…

Studies Link Climate Change to Recent Extreme Weather Events

New research in the Bulletin of the American Meteorological Society finds that climate change influenced the majority of 16 extreme weather events in 2013. Specifically, it found evidence that climate change linked to human causes—particularly burning of fossil fuels—increased the odds of nine extreme events: amplifying temperature in China, Japan, Korea, Australia and Europe; intense rain in parts of the…

World Sees Some Tangible Outcomes from U.N. Climate Summit

World leaders gathered in New York this week for the United Nations Climate Summit, a meeting aimed at raising carbon reduction ambitions and mobilizing progress toward a global climate deal. In speeches at the summit, President Obama and other leaders recognized that countries across the world are feeling climate change effects, particularly extreme weather. “In America,…

The Cost of Fixing Climate Change

Reducing greenhouse gas emissions could boost the economy rather than slow it, according to a new study by the Global Commission on the Economy and Climate. Better Growth, Better Climate: The New Climate Economy Report finds that roughly $90 trillion will be spent in the next 15 years on new infrastructure around the world. Adopting rules that redirect that…

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…

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…

Geography in the News: The Strangest Desert

By Neal Lineback and Mandy Lineback Gritzner, Geography in the NewsTM The Strange Namib Desert of Africa Africa seems to always be in the news covering conflict and disease across the continent. Its wonderful physical diversity, however, provides a background that is often overlooked by the casual reader. The Namib Desert is just one of…

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…

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…

White House Announces New Climate Change Initiatives

The White House on Wednesday announced executive actions to help states and communities build their resilience to more intense storms, high heat, sea level rise, and other effects of climate change. The actions, which involve several federal agencies, were among the recommendations by the president’s State, Local and Tribal Leaders Task Force on Climate Preparedness and Resilience. “…Climate…

Dead and Lost Boobies: Harbingers of a Growing El Niño?

Starving seabirds far from home may point to a brewing El Nino in the Pacific.

China and U.S. Sign Pacts on Climate Change

The world’s two largest carbon emitters have signed pacts to cut greenhouse gas emissions. The deals—actually eight projects demonstrating smart grids and carbon capture, utilization and storage—were made through the China-U.S. Climate Change Working Group and will involve companies and research bodies. “The significance of these two nations coming together can’t be understated,” said U.S. Secretary of State John Kerry at the…
