Record Low Arctic Sea Ice Extent Points to Irreversible Changes

Scientists at the National Snow and Ice Data Center (NSIDC) said on Monday that Arctic sea ice cover of 5.607 million square miles on March 24 represented the lowest winter maximum since records began in 1979. That’s 5,000 square miles less than last year’s record low. Contributing to the ice extent loss were record high…

February’s Record Heat Astounds Scientists

Data released last week by the National Oceanic and Atmospheric Administration (NOAA) shows that the string of monthly global heat records extended through February, when the average worldwide temperature was 2.18 degrees Fahrenheit above the 20th century average. The tenth straight record breaking month, February was the most above-normal month since meteorologists began tracking temperatures in…

U.S., Canada Announce Methane Reduction Plan

In a move that could help the United States and Canada meet pledges they made at last year’s United Nations Climate Change Conference in Paris, President Barack Obama and Canadian Prime Minister Justin Trudeau announced a plan to cut oil and gas industry methane emissions 40–45 percent, compared to 2012 levels, by 2025. In Canada,…

Supreme Court Denies Request to Block EPA’s Mercury Rule

Supreme Court Chief Justice John G. Roberts Jr. denied a request for a stay or injunction of the U.S. Environmental Protection Agency’s Mercury and Air Toxic Standards (MATS) rule—a rule that 20 states have claimed is “unlawful and beyond EPA’s statutory authority.” The ruling means MATS, which requires coal-burning power plants to install technologies to…

Study, EPA Spotlight Methane Emissions from Oil and Gas Industry

Last week, the U.S. Environmental Protection Agency (EPA) released an updated draft of its Greenhouse Gas Inventory, finding that total U.S. greenhouse gas emissions in 2014 were 6.8 billion metric tons of carbon dioxide equivalent—1 percent higher than in 2013, but 8 percent lower than the 2007 peak. The most revelatory revision: methane emissions figures…

EPA’s Clean Power Plan Faces Uncertainty

It has been more than a week since the U.S. Supreme Court issued a stay of the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan, and states are now beginning to indicate how they will approach the resulting uncertainty the decision brings. Although the stay removes the September deadline to submit compliance plans to the…

Supreme Court Events Leave Fate of Clean Power Plan Uncertain

The outlook for U.S. Environmental Protection Agency’s (EPA) Clean Power Plan, a rule intended to limit greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants, is the subject of debate after two key Supreme Court events last week. First, on Tuesday, the U.S. Supreme Court in a 5–4 decision issued a stay,…

Supreme Court Suspends Clean Power Plan

The U.S. Supreme Court blocked the Clean Power Plan, the U.S. Environmental Protection Agency’s rule limiting greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants on Tuesday. The court, in a 5–4 decision split along party lines, put a stay on enforcement of the Clean Power Plan, which is designed to cut…

Climate Change Implicated in a Specific Extreme Weather Event

Scientists have warned that even a few degrees rise in global temperatures can lead to increasingly severe storms. Now an international team of climate scientists has linked man-made climate change to historic flooding that hit the south of England in the winter of 2013–2014. It’s the first time a peer-reviewed research paper has connected climate…

Humans Implicated in String of Record-Warmth Years

Human activities are the cause of this century’s record warm years, according to a study in the journal Scientific Reports. “We find that individual record years and the observed runs of record-setting temperatures were extremely unlikely to have occurred in the absence of human-caused climate change,” the authors say. “These same record temperatures were, by…

Climate Change Tops WEF Risk Ranking

For the first time, the World Economic Forum (WEF) has ranked an environmental risk—climate change—as the most severe economic risk facing the world. Global Risks Report 2016 says climate change is compounding and intensifying other social, economic, and humanitarian stresses such as mass migration, which it ranked as the threat most likely to materialize in…

Climate and Energy of Focus in Obama’s Final State of the Union

President Obama laid out four big questions the United States has to answer in his nearly hour-long final State of the Union address Tuesday night. One of those four points: How do we make technology work for us, and not against us, especially when it comes to solving urgent issues like climate change? In discussing…

Study Says Electricity Production Vulnerable to Climate Change

A new study in the journal Nature Climate Change suggests that climate-change-related water disruptions could significantly decrease electricity production by the hydropower stations and thermoelectric (nuclear, fossil-fueled, biomass-fueled) plants that account for 98 percent of production around the world. Because the plants need water to cool generators and pump power at dams, they are vulnerable to lower…

Nations Strike Deal to Curb Carbon Emissions

The first pact to commit all countries to cut carbon emissions—the Paris Agreement—was signed by 195 countries in LeBourget, France, on Saturday. Some aspects of the agreement, which will go into effect in 2020, will be legally binding, such as submission of emissions reduction targets and regular review of progress toward them. However, the targets…

Paris Climate Talks Will Continue Past Deadline

Late yesterday, French leadership at the United Nations climate talks in Paris produced a new draft text of a global agreement calling on countries to keep temperature rise “well below” 2 degrees Celsius by 2100 but recognizing a maximum temperature rise of below 1.5 Celsius as an ideal goal. Although the talks will continue past…
