Study Finds Biofuels Worse for Climate than Gasoline

Study Finds Biofuels Worse for Climate than Gasoline

Years of number crunching that had seemed to corroborate the climate benefits of American biofuels were starkly challenged in a science journal on Thursday, with a team of scientists using a new approach to conclude that the climate would be better off without them. Based largely on comparisons of tailpipe pollution and crop growth linked to biofu… Read More

Climate Pollution Can Complicate Fishes’ Sex Lives

Climate Pollution Can Complicate Fishes’ Sex Lives

The mating rituals of male ocellated wrasses are as intricate as their shimmering scales, and new research showing that carbon dioxide pollution can affect those rituals has some scientists fretting for the future of fish. Elevated levels of carbon dioxide — which dissolves from the atmosphere into oceans, where it changes acidity levels — can … Read More

Local Efforts to Save Coral Reefs May Be Futile

Local Efforts to Save Coral Reefs May Be Futile

Scientists agree that coral reefs will continue to be decimated if climate-changing pollution from fossil fuels, farming and deforestation is not addressed. They disagree, however, over whether local efforts to restrict fishing and reduce water pollution will make meaningful differences in a world of fast-rising temperatures.… Read More

Global Climate Spending Focusing on Forest Protection

Global Climate Spending Focusing on Forest Protection

Forests straddling the equator are critical to a stable climate because they store vast amounts of carbon, and a new study finds that the U.S. and four other developed countries are spending billions of dollars to keep those forests intact. An analysis of how the U.S., Japan, Germany, France and Norway have donated money to climate change … Read More

Threat to Salmon Imperils Alaska’s Culture

Threat to Salmon Imperils Alaska’s Culture

Standing chest deep in the cold waters of the Kenai River, I can see salmon skim the surface of the water farther out in the middle of the river. I feel the tug in the big net I hold in the current and run up on shore with the net in tow to pull out the salmon. Glistening on the sand, this fish is one of the many my family will catch this summer… Read More

‘Water Windfall’ Found in Drought-Stricken California

‘Water Windfall’ Found in Drought-Stricken California

California’s Central Valley has three times more freshwater in underground aquifers than previously thought, drinking water that could help the state weather future drought and fortify itself against a changing climate, according to a new Stanford University study. But tapping that water, locked thousands of feet beneath the ground, will be … Read More

Fishing For Bright Spots in a World of Sick Reefs

Fishing For Bright Spots in a World of Sick Reefs

An unprecedented ecological analysis of fish survey findings from more than 2,500 reefs worldwide revealed on Wednesday that Muluk villagers of Karkar Island do better jobs than almost anybody in the West of managing fish stocks for the long term bounties they can provide. Karkar Island showed up as one of 15 “bright spots” in the analysis … Read More

Climate Impacts From Farming Are Getting Worse

Climate Impacts From Farming Are Getting Worse

As signs emerge that the global energy sector is beginning to rein in what once had been unbridled levels of climate-changing pollution, new United Nations figures show pollution from farming is continuing to get worse. Greenhouse gases released from the growing of crops and livestock directly increased by a little more than 1 percent in 2014 … Read More
