How Climate Scientists Parallel Early Atomic Scientists 440

Lasrick writes "Kennette Benedict writes in the Bulletin of the Atomic Scientists about the existential threat of climate change, and how the scientists who study and write about it are similar to the early atomic scientists who created, and then worried about, the threat that nuclear weapons posed to humanity: 'Just as the Manhattan Project participants could foresee the coming arms race, climate scientists today understand the consequences of deploying the technologies that defined the industrial age. They also know that action now to reduce greenhouse gas emissions will mitigate the worst consequences of climate change, just as the Manhattan Project scientists knew that early action to forestall a deadly arms race could prevent nuclear catastrophe.'"

"Dramatic Decline" Warning For Plants and Animals 696

An anonymous reader writes "Worldwide levels of the chief greenhouse gas that causes global warming have hit a milestone, reaching an amount never before encountered by humans, federal scientists said. Carbon dioxide was measured at 400 parts per million at the oldest monitoring station in Hawaii, which sets the global benchmark. More than half of plants and a third of animal species are likely to see their living space halved by 2080 if current trends continue."

Global Temperatures Are Close To 11,000-Year Peak 416

ananyo writes "Global average temperatures are now higher than they have been for about 75% of the past 11,300 years, a study published in Science suggests. Researchers have reconstructed global climate trends all the way back to when the Northern Hemisphere was emerging from the most recent ice age. They looked at 73 overlapping temperature records including sediment cores drilled from lake bottoms and sea floors around the world, and ice cores collected in Antarctica and Greenland. For some records, the researchers inferred past temperatures from the ratio of magnesium and calcium ions in the shells of microscopic creatures that had died and dropped to the ocean floor; for others, they measured the lengths of long-chain organic molecules called alkenones that were trapped in the sediments. From the first decade of the twentieth century to now, global average temperatures rose from near their coldest point since the ice age to nearly their warmest, they report (abstract)."

Texas Supreme Court Cites Mr. Spock 345

An anonymous reader writes "We always knew that Spock was wise and would probably make a pretty good judge, so perhaps it's a good thing to see the Texas Supreme Court citing Spock in a recent ruling, noting his wisdom in stating that 'the needs of the many outweigh the needs of the few.'"
