The rise in greenhouse gases in the atmosphere means far more energy is coming into Earth's climate system than is going out, but half of that energy is missing and could eventually reappear as another sign of climate change, scientists said on Thursday.
Meat from whales killed as part of Japan's "scientific" hunt was served last year in upscale sushi restaurants in Los Angeles and Seoul, according to a DNA analysis published Wednesday.
A global ban on whaling was imposed 14 years ago, but Japan has courted controversy for years by invoking an exception in the ban for scientific research and by dispatching a whaling fleet that harpoons several hundred whales a year.
There was no scientific malpractice at the University of East Anglia's Climatic Research Unit, which was at the centre of the "Climategate" affair. This is according to an independent panel chaired by Lord Oxburgh, which was convened to examine the research published by the unit.
Overuse of this seductively simple approach to weed control is starting to backfire. Use of Roundup, or its generic equivalent, glyphosate, has skyrocketed to the point that weeds are rapidly becoming resistant to the chemical. That is rendering the technology less useful, requiring farmers to start using additional herbicides, some of them more toxic than glyphosate.
“Farmer practices may be reducing the utility of some G.E. traits as pest-management tools and increasing the likelihood of a return to more environmentally damaging practices,” the report concluded. It said the problem required national attention.
Washington state filed suit Tuesday to stop the federal government from permanently abandoning the Yucca Mountain nuclear waste repository, marking the latest clash in a long-standing dispute over where the nation's nastiest radioactive waste should be stored.
Waste and spent nuclear fuel from south-central Washington's Tri-Cities, site of the highly contaminated Hanford nuclear reservation and the Northwest's only commercial nuclear plant, had long been intended to go to Yucca Mountain.
Glacier National Park has lost two more of its namesake moving icefields to climate change, which is shrinking the rivers of ice until they grind to a halt, a government researcher said Wednesday.
Warmer temperatures have reduced the number of named glaciers in the northwestern Montana park to 25, said Dan Fagre said, an ecologist with the U.S. Geological Survey. He warned many of the rest of the glaciers may be gone by the end of the decade.
"It's continual," Fagre said. "When we're measuring glacier margins, by the time we go home the glacier is already smaller than what we've measured." The meltoff shows the climate is changing, but does not show exactly what is causing temperatures to go up, Fagre said.
