This summer is ‘what global warming looks like’

WASHINGTON (AP) — Is it just freakish weather or something more? Climate scientists suggest that if you want a glimpse of some of the worst of global warming, take a look at U.S. weather in recent weeks.

Rising sea levels can’t be stopped, scientists say

LONDON — Rising sea levels cannot be stopped over the next several hundred years, even if deep emissions cuts lower global average temperatures, but they can be slowed down, climate scientists said in a new study.

Top U.S. Science Official: ‘Climate Change Is Under Way…It’s Having Consequences In Real Time’

One of America’s top science officials says the current onslaught of extreme weather in the U.S. is raising awareness of climate change among Americans.

What Is Causing The Climate To Unravel?

40,000 heat records have already been broken this year across the  United States, according to the National Oceanic and Atmospheric  Administration. Here in Fredericksburg, Virginia, the signs of an  unbalanced climate system have been felt in recent years not just in  heatwaves, but increasingly in the form of unusually severe wind storms.  This past weekend’s storm brought 80 mph wind gusts that snapped three  trees in our backyard like pretzels, even though they were each a foot  thick. Once again, my insurance company is teaching me new weather  terminolgy to explain the latest climate disasters. A few years ago, the  term was “micro-bursts” (not quite tornadoes, but similar impact). Now  it is “derecho” (not quite hurricanes, but similar impact).

Nitrogen pollution changing Rocky Mountain National Park vegetation, says CU-Boulder-led study

A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park. The emissions of nitrogen compounds to the atmosphere are being carried to remote areas of the park, altering sensitive ecosystems, said CU-Boulder Professor William Bowman, who directs CU-Boulder’s Mountain Research Station west of Boulder and who led the study. “The changes are subtle, but important,” he said. “They represent a first step in a series of changes which may be relatively irreversible.”

Heat, Rainfall Affect Pathogenic Mosquito Abundance in Catch Basins

ScienceDaily (July 6, 2012) — Rainfall and temperature affect the abundance of two mosquito species linked to West Nile Virus in storm catch basins in suburban Chicago, two University of Illinois researchers report.

Climate change suspended reef growth for 2 millennia

Climate change drove coral reefs to a total ecosystem collapse lasting thousands of years, according to a paper published this week in Science. The paper shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago, corresponds to a period of dramatic swings in the El Niño-Southern Oscillation (ENSO). “As humans continue to pump greenhouse gases into the atmosphere, the climate is once again on the threshold of a new regime, with dire consequences for reef ecosystems unless we get control of climate change,” said coauthor Richard Aronson, a biology professor at Florida Institute of Technology.

Canada’s Inuit roar in protest over move to protect polar bears

They say animal rights activists put the species at more risk than hunters who regard it as central to their livelihood.

Solar plane flies to Madrid Friday

The Swiss-made, solar-powered aircraft Solar Impulse piloted by Bertrand Piccard of Switzerland takes off from Rabat in June 2012. The aircraft will leave the Moroccan capital on Friday for Madrid on its return journey to its home port in Switzerland, Morocco’s news agency MAP reported.

US Drought Monitor shows record-breaking expanse of drought across US

More of the United States is in moderate drought or worse than at any other time in the 12-year history of the U.S. Drought Monitor, officials from the National Drought Mitigation Center at the University of Nebraska-Lincoln said July 5. Analysis of the latest drought monitor data revealed that 46.84 percent of the nation’s land area is in various stages of drought, up from 42.8 percent a week ago. Previous records were 45.87 percent in drought on Aug. 26, 2003, and 45.64 percent on Sept. 10, 2002.
