Landmark Carbon Dioxide Concentration Passed; Marks New Climate Era

Climate change has entered a new phase, said the United Nations World Meteorological Organization (WMO) on Monday. The WMO reported that concentrations of carbon dioxide (CO2) “surged again to new records in 2016,” and it predicted that the annual average for CO2 would remain above 400 parts per million (ppm), 44 percent higher than before…

Climate, Energy Get Little Attention in Second Presidential Debate

A week after the Paris Agreement to limit global warming met requirements to come into force, the subject of climate change was referenced only once in Tuesday’s second U.S. presidential debate—after audience member Ken Bone posed the question “What steps will your energy policy take to meet our energy needs while at the same time…

European Union Ratification Pushes Paris Agreement into Effect

European Union (EU) environment ministers on Friday approved ratification of the Paris Agreement. The approximately one-month EU ratification process means that the requirements for a 30-day countdown for the agreement to take effect will be met in November. “Today is an important day not only for our action on climate but also for unity we have…

Clean Power Plan Goes to Court

What was scheduled to be about 3.5 hours turned into nearly seven on Tuesday as 10 judges heard oral arguments in a rare “en banc” review of the Clean Power Plan in the U.S. Court of Appeals for the District of Columbia Circuit. The controversial Clean Power Plan, based on Section 111(d) of the Clean…

Paris Agreement Closer to Being Ratified

Thirty-one new countries formally agreed to join the Paris Agreement to reduce global emissions—bringing the total committed countries to 60. The Paris Agreement takes effect when it is formally adopted by at least 55 countries representing at least 55 percent of global greenhouse gas emissions. Yet, so far, these 60 country commitments only account for 48…

California Increases Climate Ambitions with Landmark Legislation

Two laws signed by Gov. Jerry Brown will ratchet up California’s fight against climate change by launching efforts to reduce emissions 40 percent below 1990 levels by 2030. SB-32 calls for increased renewable energy use, more electric cars, improved energy efficiency, and emissions cuts from key industries. AB-197 provides aid to low-income or minority communities…

G20 Summit: Commitment to Climate Change Action Reaffirmed but Details Lacking

As G20 leaders concluded their meeting in Hangzhou on Monday, they reaffirmed their commitment to addressing climate change, but they did not agree on deadlines to ratify the Paris Agreement limiting Earth’s temperature increase to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius (subscription).…

Release of Carbon from Melting Permafrost Could Trigger Rapid Warming

A study published last week in Nature Geoscience provides the first measurements of greenhouse gases from permafrost under Arctic lakes in Alaska, Siberia, and Canada. Although the research reveals that only a small amount of old carbon has been released in the past 60 years, it also suggests that much more could be released as…

Americans View of Climate Change Polarized; U.N. Targets May Be Tough to Achieve

Surveys conducted by Yale University and George Mason University suggest that 17 percent of Americans view climate change as an alarming threat and that another 28 percent are concerned about climate change but view it as a distant threat. The subject has become highly contentious since 1997, when then Vice President Gore helped broker an…

New York Joins Handful of Other States with Ambitious Clean Energy Targets

By 2030, half of the energy produced in the state of New York will come from renewables, according to a new policy adopted Monday by the state’s public service commission. The move is expected to reduce greenhouse gas emissions by 40 percent from 1990 levels (80 percent by 2050) and to attract billions in clean…

Survey, Party Platforms Reveal Deep Divide on Climate Change

In March, the Guardian issued an election-related call-out to online readers in the United States, asking them to identify the “one issue that affects your life you wish the presidential candidates were discussing more.” The results are in. Of the 1,385 respondents from all 50 states, one in five expressed discontent about lack of discussion…

Natural Fluctuations Responsible, in Part, for Antarctica Ice Growth

Natural fluctuations specifically related to the Interdecadal Pacific Oscillation (IPO) are responsible for the increased growth of Antarctic sea ice, according to a new study in the journal Nature Geoscience. A negative shift in the IPO has caused cooler-than-average sea surface temperatures in the Eastern Pacific, allowing Antarctic sea ice to expand since 2000. “The…

North American Leaders Commit to Clean Energy Goal

At the North American Leaders Summit on Wednesday, Mexico, Canada and the United States pledged to generate 50 percent of their energy from clean sources by 2025. The joint commitment by the three countries, according to White House Adviser Brian Deese, is “an aggressive goal” but one that is “achievable continent-wide.” “The Paris Agreement was…

Climate Change Poses Threat to World Heritage Sites

Yellowstone National Park, Venice, Jordan’s Wadi Rum, and Easter Island’s Rapa Nui National Park are some of the 31 natural and cultural World Heritage sites in 29 countries that are threatened by climate change according to a new report released by UNESCO, the United Nations Environment Program and the Union of Concerned Scientists. Melting glaciers,…

Melting of Totten Glacier Could Trigger 6 Foot Sea-Level Rise

A new study published in the journal Nature is drawing attention to the effect of warming water on the world’s largest ice mass, Totten Glacier in East Antarctica. Melting of the glacier, which has an ice catchment area bigger than California, could lift oceans at least two meters (6.56 feet). According to researchers who mapped the shape of…
