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…

Studies Make Predictions about Climate Change Impacts

Limiting global average 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—as agreed at the United Nations Climate Change Conference in Paris last year—will do little to stop portions of the world from becoming uninhabitable. That’s according to a new study…

Informal settlements and climate change: An opportunity and challenge for cities of emerging economies

By Mayor Mpho Parks Tau of Johannesburg The unprecedented growth of cities in emerging economies, coupled with the legacy of apartheid in South Africa has, since the early 1990s, led to a rapid increase in informal settlements, or slums, in Johannesburg. As the economic heartland of South Africa, it is estimated that Johannesburg receives more…

Study: Half a Degree Matters

Last week more than 150 nations signed the Paris Agreement, pledging to hold the increase in the global average temperature to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. Now, the first comprehensive analysis of the impacts of that half centigrade difference…

A Pacific salmon hub is under threat

The Skeena River snakes out of fir-lined fjords on the misty northern coast of British Columbia, and washes over a thousand-acre sandbar. Flora Bank is a biological bottleneck over which millions of finger-length young salmon enter the sea each spring. Scientist Allen Gottesfeld calls Flora Bank the “Grand Central Station” for the watershed. All streams…

Wolf – Caribou Detente? Clues Hidden on Lake Superior Islands

Qalipu, it’s called by Canada’s Mi’kmaq people. To others, it’s the elusive gray ghost of the far northern forest. Most know it simply as caribou. Woodland caribou are medium-sized members of the deer family. In Canadian provinces such as Ontario, these shadows in the forest are listed as threatened – quickly vanishing. Non-migratory woodland caribou…

Nations to Sign Paris Climate Agreement Friday

Four months after it was finalized by delegates to the Paris Climate Change Conference, the Paris Agreement will be signed by more than 100 nations on Friday. While the agreement is facially insufficient to meet its overall emissions objectives, the signing of the Paris agreement nevertheless is significant. It brings into effect the approach and…

Uncharted Arctic waters: A new opportunity for exploitation, or conservation?

Co-authored by Erica Cirino When thick sheets of sea ice began melting in the Arctic waters around Svalbard, Norway, a few years ago, a new expanse of sparkling blue sea opened up. As climate change continues to drive ice melt here on the previously untouched waters of the North Barents Sea, what many ocean conservationists…

Climate-Change-Related Precipitation Extremes Hard to Predict

Scientists have warned that severe drought and precipitation are among the risks of greenhouse-gas-induced climate change, but a study published in the journal Nature finds that extremely warm temperatures do not always translate into record wet and dry extremes. Highlighting the complexities in predicting the effects of planetary warming on precipitation, lead author Fredrik Ljungqvist…
