Photos: Climate change is making California look like another planet

Quartz: When Thomas Heinser showed his pictures of California's parched landscape in a gallery last month, people couldn't tell what they were looking at. Last year marked the driest summer California has seen in at last 500 years, causing water shortages and resulting in forest fires throughout the state. Shot from the side of a doorless helicopter, Heinser's aerial photographs look more like abstract art than fields and valleys--driving home the transformative effects of climate change in California....

The alarming science driving much higher sea level projections for this century

Washington Post: For many scientists studying Antarctica, and particularly the vulnerable West Antarctic ice sheet, a major new study significantly increasing expectations for sea-level rise is the culmination of a large body of prior research -- combined with alarming recent observations. The study, just published in Nature, is based on an improved understanding of past warm eras in Earth’s history that featured much higher seas. By creating advanced computer simulations of how Antarctica’s ice melts and flows...

Scientists nearly double sea level rise projections for 2100, because of Antarctica

Washington Post: Sea levels could rise nearly twice as much as previously predicted by the end of this century if carbon dioxide emissions continue unabated, an outcome that could devastate coastal communities around the globe, according to new research published Wednesday. The main reason? Antarctica. Scientists behind a new study published in the journal Nature used sophisticated computer models to decipher a longstanding riddle about how the massive, mostly uninhabited continent surrendered so much ice during...

‘High risk’ of severe water stresses in Asia by 2050

CNBC: Some 1 billion people in Asia could be without water by 2050, according to new research. A group of researchers at the Massachusetts Institute of Technology says there is a "high risk of severe water stress" across large patches of Asia, home to a big chunk of the world's population. The primary driver of this water stress will not necessarily be climate change, according to the study published Wednesday in the peer-reviewed journal PLoS One. "We find that water needs related to socioeconomic...

EPA aims to cut methane leaks from natural gas companies

Associated Press: The Obama administration on Wednesday announced a new partnership with 41 energy companies that have agreed to voluntarily reduce methane emissions from natural gas operations to help combat climate change. The Environmental Protection Agency unveiled the Natural Gas STAR Methane Challenge Program at this week's Global Methane Forum held in Washington. Methane is a potent greenhouse gas, capable of trapping 25 times more heat in the atmosphere than an equivalent amount of carbon dioxide. EPA Administrator...

Trump, Cruz vow to undo Obama environmental work

Hill: In responding to a survey from the American Energy Alliance, both candidates said they would undo major Obama-era Environmental Protection Agency rules on clean water and power plant carbon emissions, with Trump saying, “under my administration, all EPA rules will be reviewed.” Both candidates said they oppose a carbon tax, a policy Obama has praised but not pushed while president. “The observed temperature evidence does not support the claims that carbon dioxide is dangerous,” Cruz wrote in...

Antarctic model raises prospect of unstoppable ice collapse

Nature: Recent studies suggest that the Antarctic ice sheet is much less stable than scientists once thought. Choices that the world makes this century could determine the fate of the massive Antarctic ice sheet. A study published online this week in Nature1 finds that continued growth in greenhouse-gas emissions over the next several decades could trigger an unstoppable collapse of Antarctica’s ice -- raising sea levels by more than a metre by 2100 and more than 15 metres by 2500. “That is literally...

California’s Sierra Snowpack Shows Improvement; Drought Still Not Over

National Public Radio: Updated snowpack measurements show El Nino has helped ease the drought in California. While reservoirs are filling up, conservation measures remain in place.

Study: Antarctic ice may melt faster than expected

Associated Press: Warmer air, less frigid water and gravity may combine to make parts of Antarctica's western ice sheet melt far faster than scientists had thought, raising sea levels much more than expected by the end of the century, according to a new study. New physics-based computer simulations forecast dramatic increases in melting in the vulnerable western edge of the continent. In a worst case scenario, that could raise sea level in 2100 by 18 to 34 inches (46 to 86 centimeters) more than an international...

Cold War-era Alaskan tunnel yields clues on climate

ClimateWire: Ten miles north of Fairbanks, along a man-made valley cleared by industrial gold dredgers in the early 1900s, a small red building at the base of a hill provides a portal to the geologic history of central Alaska. Behind a locked metal door lies the Cold Regions Research and Engineering Laboratory, a 360-foot tunnel that gives scientists hands-on, underground access to frozen permafrost dating from the present to nearly 50,000 years in the past. Operated by the Army Corps of Engineers and the...
