WASHINGTON (Reuters) – A changing climate means allergy-causing ragweed pollen has a longer season that extends further north than it did just 16 years ago, U.S. scientists reported Monday.
In research that gibes with projections by the U.N. Intergovernmental Panel on Climate Change, plant and allergy experts found that ragweed pollen season lasted as much as 27 days longer in 2009 than it did in 1995. The further north in the Western Hemisphere, the more dramatic the change in the length of pollen season.
WASHINGTON (Reuters) – Rising seas spurred by climate change could threaten 180 U.S. coastal cities by 2100, a new study says, with Miami, New Orleans and Virginia Beach among those most severely affected.
Previous studies have looked at where rising waters might go by the end of this century, assuming various levels of sea level rise, but this latest research focused on municipalities in the contiguous 48 states with population of 50,000 or more.
What happens when the airport scanner shows shapes that look like live spiders, snakes, lizards and tortoises inside three big suitcases? Last week in Bangkok, it meant the detention of an Indonesian man and the seizure of 259 live creatures that were slotted into compartments in the black traveling bags.
The suspected smuggler reportedly went on a wildlife shopping spree in Bangkok’s Chatuchak Market, a hub for rare animal trade, according to conservation group TRAFFIC, which monitors illegal trafficking of species.
Another winter storm is brewing in Middle America. So what else is new?
It’s been one spate of severe weather after another even before 2011 began. And you would expect those skeptical of climate change to capitalize on the cold snap by questioning whether human-spurred global warming is a real deal.
Strangely enough, climate skeptics appear to be less vocal than they were last year, when Republican Sen. James Inhofe of Oklahoma built an igloo as a blizzard blew through Washington DC, and dubbed it “Al Gore’s new home.” If it’s so cold, the argument went, how can there be global warming?
WASHINGTON (Reuters) – Polar bear mothers will have a harder time carrying cubs to term as Arctic sea ice dwindles, a new study said, and the U.S. government recognized that Pacific walruses need protection in their melting icy habitat.
Arctic ice reached the third-lowest level ever recorded in 2010, and was at record low levels in January. Because the Arctic is a major weather-maker for much of the Northern Hemisphere, these changes are being blamed for severe storms in some of the world’s most densely populated areas.
WASHINGTON (Reuters) – Remember 2010? U.S. and international scientists reckon it tied for the warmest year on record, supporting findings of unequivocal global climate change. Climate skeptics remain unconvinced.
Those who study the climate skeptic position say this raises echoes of scientific controversies of the past, including the debate over the health hazards of tobacco.
The one word that leaped out of President Obama’s State of the Union address to Congress wasn’t “optimism,” “business,” “teachers,” “economy” or “budget.”
To those who listened to the speech on National Public Radio, the memorable term was “salmon,” writ large in a word cloud NPR compiled from its listeners after Obama finished.
The Chinese flags have disappeared from Washington’s wide avenues after China’s President Hu Jintao’s visit this week, but one statistic is still in the air: the rapidly expanding size of the Chinese ecological footprint, compared to the huge but slowing impact U.S. consumers have on global supplies of food, water, fuel — everything, really.
China and the United States are generally considered to hold the top two spots in the world for emissions of climate-warming greenhouse gases. But how do they compare when consumption of all goods is taken into account?
Greenland’s ice sheet melted at a record rate in 2010, and this could be a major contributor to sea level rise in coming decades.
The ice in Greenland melted so much last year that it formed rivers and lakes on top of the vast series of glaciers that covers much of the big Arctic island, with waterfalls flowing through cracks and holes toward the bottom of the ice sheet. Take a look at video from Marco Tedesco of City College of New York, who is leading a project to study what factors affect ice sheet melting. The photo at left shows a camp by the side of a stream flowing from a lake — all of it on top of the ice sheet.
The latest chapter in the long story of panda diplomacy was written at Washington’s National Zoo, where the Chinese government agreed to lengthen the “loan” of popular panda pair Mei Xiang and Tian Tian for another five years. Actually, the loan is conditioned on whether they produce a new heir or heiress to the cuteness of panda-dom in the next two years; one or both could be exchanged for more fecund substitutes.
They have a good track record: Washington native Tai Shan, born in 2005, headed back to China last year.
