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…

Study Quantifies Climate-Change-Related Deaths

A study in Environmental Research Letters suggests a fifth of premature deaths during a 2003 heatwave in Europe are linked to human-caused climate change. “We are now able to put a number on the deaths caused by climate change in a heat wave,” said lead author Daniel Mitchell of the University of Oxford. “This has…

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…

More ocean acidification, less coral?

Co-authored by Erica Cirino Scientists have known for about 15 years that ocean acidification has made it more difficult for hard corals and shelled marine organisms to survive. To grow, hard corals as well as clams, oysters, and others pull calcium and carbonate molecules out of the water and join them together to create calcium…

This Decade’s Most Important Climate Solution

By Justin Adams, Global Managing Director for Lands at The Nature Conservancy “A geo-engineering solution, but without any of the risk.” That’s how Jeff Seabright, Unilever’s Chief Sustainability Officer, described nature’s role in carbon mitigation at the Business & Climate Summit 2016 in London. We all know meeting the world’s new commitment to limit global…

Lord Mayor of Sydney Clover Moore on a bold new plan for a green and resilient future

By Clover Moore, Lord Mayor of Sydney This week, the City of Sydney agreed on ambitious new targets for 50 per cent of electricity used in the local area to come from renewable energy by 2030, and for net zero emissions by 2050. We have already committed to our long-term vision, Sustainable Sydney 2030, a program to…

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…

Coral Reef Bleaching Event Forecast to Worsen; NASA Studies Cause in Pacific

Coral in every major reef region across the world has already experienced bleaching, and the National Oceanic and Atmospheric Administration (NOAA) forecasts that temperatures in much of the Pacific, Atlantic and Indian oceans could reach a point at which significant bleaching of corals is present this summer. NOAA’s Coral Reef Watch suggests that the greatest…

Coral Bleaching Linked to Climate Change, Other Factors

The Great Barrier Reef, which last year narrowly avoided being put on the World Heritage endangered list, is experiencing its worst bleaching in recorded history. According to the Great Barrier Reef Marine Park Authority, overall mortality of the reef is 22 percent, but along Lizard Island, off far north Queensland, it’s 93 percent. Coral bleaching is also occurring along…

On World Oceans Day, A View from the Top

A conversation with Bertrand Piccard, the scientist-adventurer currently on the American leg of his global solar flight on the Solar Impulse 2, on the view from 28,000 feet, how we nearly turned our ocean into a dump for nuclear waste and win-win solutions for a healthy planet. We spoke on the eve of World Oceans Day.…

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,…

Uncertainties Cloud Forecast For 2016 Hurricane Season

Meteorologists with the National Oceanic and Atmospheric Administration think as many as 16 named tropical storms could form in the Atlantic Basin—which includes the Gulf of Mexico, Caribbean Sea and Atlantic Ocean—during the 2016 hurricane season, which begins June 1. A summer that produced 16 named storms would be well above the dozen storms that…

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…

Clean Power Plan Court Hearing Delayed to September

Just weeks before the U.S. Court of Appeals for the D.C. Circuit was scheduled to hear challenges to the 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, the court announced it will push the hearing back four monthsand…

Study Links Vanishing of Solomon Islands to Anthropogenic Climate Change

A study published in the journal Environmental Research Letters finds that five of the uninhabitated Solomon Islands have submerged underwater and six more have experienced dramatic shoreline reductions due to man-made climate change. The study by a team of Australian researchers offers scientific evidence confirming anecdotal accounts of climate change impacts on Pacific islands. That evidence…
