Earth Changes
DROUGHT-BREAKING rains across eastern Australia have been predicted in new modelling by a scientist who believes massive pulses in the sun's magnetic field are helping to drive the Earth's climate systems.
BRUSSELS - The United States must act to cap its emissions of greenhouse gases and join the fight against climate change or risk losing global leadership, a former CIA director said in a report released on Monday.
"The United States must adopt a carbon emission control policy," John Deutch, head of the Central Intelligence Agency in 1995-96, said in a report to the Trilateral Commission, a grouping of business and opinion leaders from Europe, the United States and Asia.

PHOENIX -- For the fifth consecutive day, the mercury sweated out another record high temperature.
It was 94 degrees Sunday, breaking the old record for the date of 91 degrees set in 2004.
Sunday morning's low of 65 degrees also established a record for the warmest minimum temperature for the date, breaking the old mark of 62 set in 2004.

VIENNA, Austria - It looks like a color-coded terror alert scale - and meteorologically speaking, that's exactly what it is. With climate change making conditions more unpredictable, national weather services from across the European Union have joined forces to create http://www.meteoalarm.eu - a new Web site providing up-to-the-minute information on "extreme weather" across the continent.
The initiative, managed by Austria's Central Institute for Meteorology and Geodynamics, is designed to give Europeans a single source for details on flash floods, severe thunderstorms, gale-force winds, heat waves, blizzards and other violent weather that poses a threat to life or property.

Some say the world will end in fire, some say in ice, wrote Robert Frost. But whatever is to be our fate, it is now overdue.
After analysing the eradication of millions of ancient species, scientists have found that a mass extinction is due any moment now.
Their research has shown that every 62 million years - plus or minus 3m years - creatures are wiped from the planet's surface in massive numbers.

It is already painfully clear that models of anthropogenic global warming are ridiculously inadequate, and do not meet the basic tests of experimental science, no matter how many "scientists" yell "consensus." Now comes a serious question from a serious scientist that threatens to undermine the fundamental premise of the alarmists.
Danish physicist Bjarne Andresen has raised the interesting point that there may be no global warming, because there is no such thing as global temperature! That is because the earth atmosphere is not a homogeneous system. It's not a glass lab jar in your high school physics lab.

COMMERCE CITY, Colo. - On the prairie where her ancestors once blanketed the landscape, a bison yearling lifted up her muzzle and pirouetted before bounding off in the shadow of the Rocky Mountains.
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases --sunlight blocked by dust, pollution and other aerosol particles -- appears to have lost ground.
The thinning of Earth's "sunscreen" of aerosols since the early 1990s could have given an extra push to the rise in global surface temperatures. The finding, published today in the journal Science, may lead to an improved understanding of recent climate change. In a related study published last week, scientists found that the opposing forces of global warming and the cooling from aerosol-induced "global dimming" can occur at the same time.
"When more sunlight can get through the atmosphere and warm Earth's surface, you're going to have an effect on climate and temperature," said lead author Michael Mishchenko of NASA's Goddard Institute for Space Studies (GISS), New York. "Knowing what aerosols are doing globally gives us an important missing piece of the big picture of the forces at work on climate."

Lancaster County is getting own March Madness today, courtesy of Mother Nature.
The county awoke to rain, which turned to slushy sleet, which turned to snow, which was supposed to accumulate 4 to 8 inches by midnight in most areas of the county.
Northern and higher areas of the county could get more snow, maybe close to a foot, said Eric Horst, Millersville University meteorologist.
This late-season snow surge comes, of course, on the heels of near 80-degree weather earlier this week, and ahead of 60-ish weather that's supposed to return next week.
"Whatever snow we get, most of it is gone after the weekend," Horst said. "That's a hallmark of spring storms. It doesn't last."

A catastrophic collapse of the Arctic sea ice could lead to radical climate changes in the northern hemisphere according to scientists who warn that the rapid melting is at a "tipping point" beyond which it may not recover.
The scientists attribute the loss of some 38,000 square miles of sea ice - an area the size of Alaska - to rising levels of carbon dioxide in the atmosphere as well as to natural variability in Arctic ice.
