Melting glaciers might be making ocean water more acidic, an unexpected finding that's given scientists new cause for concern. A new study published yesterday in the journal Nature Climate Change suggests surprising ways that climate change is drastically altering the water chemistry in deep seas—a process that may happen faster than researchers anticipated.
A Senate committee approved Kathleen Hartnett White, a climate change skeptic and former chairwoman of the Texas Commission on Environmental Quality, for a top environmental post Wednesday. Voting along party lines, the Senate’s Environment and Public Works committee approved White to head the Council on Environmental Quality. Her nomination must be approved by the full Senate before she is confirmed.
To graduate student Sarah Fortune, the rocky crags off Baffin Island were just part of its stark beauty. Then, she saw a group of eight bowhead whales rubbing their bodies against the large boulders. Using aerial drones to watch the whales, she saw that they were using the rocks to help remove loose, dead skin.
Australian scientists are optimistic that a fertility treatment for coral could help regenerate the Great Barrier Reef. The 2,300 kilometer long coral reef -- a UNESCO World Heritage Site -- has been extensively damaged by a process known as coral bleaching in which warm water stresses the organism and causes it to die.
There are a lot of scientific eyes on west Antarctica right now, for some pretty obvious reasons. The West Antarctic Ice Sheet (WAIS) holds a lot of water – enough to push up sea levels around the world by 3m or so.
When Alifereti Tawake was a boy growing up on Fiji's Kadavu Island, his grandfather would go out fishing in the morning and return before Tawake left for school. "That would be my lunch," Tawake says. "Fresh fish." Over time, his grandfather would stay out for longer and longer stretches of time, until one day in 1988 when he didn't come back at all; his family believes that he died at sea. By then, it was clear to many Fijian fishermen that the marine resources they harvested for food and livelihoods were dwindling. Fiji's shift from a subsistence economy to a commercial one left its coasts largely depleted.
Researchers want to enlist surfers, scuba divers and anglers to monitor hard-to-reach areas vulnerable to climate change. Satellites are good at measuring temperatures over vast stretches of ocean, but less accurate at monitoring a particularly important type of marine environment—coastlines. Now help could come from an unlikely source: a water sports “navy” of surfers, anglers, scuba divers and others. A U.K.-led team of researchers has proposed this alliance to help gather coastal climate data in a recent paper in Frontiers in Marine Science.
Member Highlight: Pacific Island Countries Could Lose 50-80 Percent Of Fish In Local Waters Under Climate Change
Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new Nippon Foundation-Nereus Program study published in Marine Policy. This area of the ocean is projected to be the most severely impacted by aspects of climate change.

The Senate Commerce, Science, and Transportation Committee held a hearing to consider four presidential nominees subject to Senate confirmation, including The Honorable James Bridenstine (OK-1) to be Administrator of the National Aeronautics and Space Administration (NASA) and Dr. Neil Jacobs to be Assistant Secretary of Commerce, Environmental Observation and Prediction at National Oceanic and Atmospheric Administration (NOAA).
The House Oversight and Government Reform Subcommittee on Interior, Energy, and Environment held a hearing, “Examining the Regulation of Shark Finning in the United States.” There are nearly 500 species of sharks, and these top predators play a key role in maintaining ecosystem balance, which allows for thriving fisheries, robust habitats, and a healthy ocean. In turn, a healthy ocean is critical to life on this planet – from supplying oxygen and food to its role in international commerce.
Climate change is real. It’s caused by greenhouse-gas pollution released by human industrial activity. Its consequences can already be felt across every region and coastline of the United States—and, unless we stop emitting greenhouse gases soon, those consequences will almost certainly get worse. Those are the headline findings of the Climate Science Special Report, a sweeping and more than 800-page examination of the evidence. The report was published Friday by four agencies of the U.S. government and academics from across the country.
Environmental disturbances such as El Niño shake up the marine food web off Southern California, new research shows, countering conventional thinking that the hierarchy of who-eats-who in the ocean remains largely constant over time.
According to the study released last week by the National Academies of Sciences, titled "Sustaining Ocean Observations to Understand Future Changes in Earth's Climate," the U.S. must expand its fleet of research vessels to accurately measure and assess the effects of climate change.
If all the land ice present on Earth today were to melt, it would raise the global sea levels by about 70 meters (230 feet), according to the United States Geological Survey. Under the onslaught of global warming, sea levels have been rising steadily in the recent years, but researchers looking at historical data have found these rise could happen in sharp bursts instead.
The U.S. Fish and Wildlife Service (USFWS) has moved to remove Endangered Species Act protections from Pacific Walruses, citing their ability to adapt and persist during changes in their climate and environment.

If current carbon emissions and climate trends hold, the Far North can join the hurricane-soaked South as a place of wet-weather extremes, new research shows. Climate warming is likely to bring more episodes of heavy rain, above-freezing winter thaws and scorching hot summer days in the coming decades, says a study by scientists at the University of Alaska Fairbanks. By the end of the century, one-day maximum rainfalls will be 53 percent heavier than what is now considered the norm — the weather recorded from 1981 to 2010 — and maximum five-day rainfalls will be 50 percent heavier, according to the study.
Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean. Ice-covered sea areas in the Arctic Ocean during summer have nearly halved since the 1970s and 1980s, raising alarm that the ocean is shifting from a multiyear to a seasonal ice zone. The Intergovernmental Panel on Climate Change (IPCC) has forecasted summer ice cover in the polar ocean might disappear almost completely as early as 2050. Various factors have been cited as causes, including rising temperatures and changes in atmospheric circulation patterns.
