"Only an insignificant fraction of scientists deny the global warming crisis. The time for debate is over. The science is settled."
So said Al Gore ... in 1992. Amazingly, he made his claims despite much evidence of their falsity.

Kelly Goodwin sifted through the rubble of what used to be her kitchen, dazed after a tornado ripped through eastern Iowa and flattened dozens of homes in three communities.

A cold snap in Argentina led to electricity and natural gas shortages this week, idling factories and taxis and causing sporadic blackouts in the capital.
Beset by the coldest May since 1962, millions of residents fired up space heaters, straining Buenos Aires' electrical grid for three nights and forcing authorities to slash power supply nationwide and briefly cut domestic natural gas provisions and exports to Chile.

Although the chemical known as deet currently dominates the mosquito-repellent market, nature is full of bug-banishing strategies.
Native Americans once smeared goldenseal root on their bodies to ward off bites. And today candles made with oil from citronella grass help keep the bugs away from backyard barbecues.
Now a team of Australian researchers has isolated one of the most effective natural mosquito repellents yet from an unlikely source: smelly frog skin.
Craig Williams is an ecologist at the University of Adelaide in Australia who led the research team.
"Because frogs have delicate skins designed for absorbing water from their environment, they are vulnerable to things like infections, predators, and [parasites that live in skin]," he said
"So frog skin is really a portable pharmacy" full of chemicals for keeping the amphibians healthy.

MIAMI - Tropical Storm Barry formed in the Gulf of Mexico on Friday _ the first day of hurricane season _ and the National Hurricane Center issued a tropical storm warning for a stretch of Florida's western coast.
NASA Administrator Michael Griffin faces a storm of ridicule after saying on National Public Radio that humans shouldn't try to solve the global warming problem. Griffin also told NPR that NASA isn't officially authorized to take any action to impact climate change in one way on another.
A small earthquake rattled a desert town near the U.S.-Mexico border on Thursday, although there were no immediate reports of damage or injuries.
The magnitude-3.9 temblor struck at 7:08 p.m. and was centered eight miles southwest of Ocotillo, about 10 miles north of the border, according to a preliminary report from the U.S. Geological Survey.
