NASA study solves case of Earth's 'missing energy'

Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colo., released a study claiming that inconsistencies between satellite observations of Earth’s heat and measurements of ocean heating amounted to evidence of “missing energy” in the planet’s system.

Where was it going? Or, they wondered, was something wrong with the way researchers tracked energy as it was absorbed from the sun and emitted back into space?

An international team of atmospheric scientists and oceanographers, led by Norman Loeb of NASA’s Langley Research Center in Hampton, Va., and including Graeme Stephens of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., set out to investigate the mystery.

They used 10 years of data — spanning 2001 to 2010 — from NASA Langley’s orbiting Clouds and the Earth’s Radiant Energy System Experiment (CERES) instruments to measure changes in the net radiation balance at the top of Earth’s atmosphere. The CERES data were then combined with estimates of the heat content of Earth’s ocean from three independent ocean-sensor sources.

Their analysis, summarized in a NASA-led study published Jan. 22 in the journal Nature Geosciences, found that the satellite and ocean measurements are, in fact, in broad agreement once observational uncertainties are factored in.

Space Daily - First ever direct measurement of the Earth's rotation

The Earth wobbles. Like a spinning top touched in mid-spin, its rotational axis fluctuates in relation to space. This is partly caused by gravitation from the sun and the moon. At the same time, the Earth's rotational axis constantly changes relative to the Earth's surface. On the one hand, this is caused by variation in atmospheric pressure, ocean loading and wind.

These elements combine in an effect known as the Chandler wobble to create polar motion. Named after the scientist who discovered it, this phenomenon has a period of around 435 days. On the other hand, an event known as the "annual wobble" causes the rotational axis to move over a period of a year.

This is due to the Earth's elliptical orbit around the sun. These two effects cause the Earth's axis to migrate irregularly along a circular path with a radius of up to six meters.

Capturing these movements is crucial to create a reliable coordinate system that can feed navigation systems or project trajectory paths in space travel.

NASA - Climate Change May Modify Half Earth's Plants

Published on Friday, December 16, 2011 by Cosmos Magazine

PASADENA - By 2100, global climate change will modify plant communities covering almost half of Earth's land surface.

Climate change will also drive the conversion of nearly 40% of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another, according to a new NASA and university computer modelling study.

"For more than 25 years, scientists have warned of the dangers of human-induced climate change," said Jon Bergengren, a scientist who led the study while a postdoctoral scholar at the California Institute of Technology in the U.S..

"Our study introduces a new view of climate change, exploring the ecological implications of a few degrees of global warming. While warnings of melting glaciers, rising sea levels and other environmental changes are illustrative and important, ultimately, it's the ecological consequences that matter most."

Michael Collins - Oops! We're Doomed

http://www.opednews.com/articles/Oops-We-re-Doomed-by-Michael-Collins-111215-68.html

December 15, 2011 By Michael Collins We don't have a substantial cushion between today's climate and dangerous warming. James E. Hanson The head of NASA's Goddard Institute for Space Studies, James E. Hansen, announced the results of break through global warming research last week. The earth's temperature is rising at a much quicker pace than previously anticipated according to research by the nation's preeminent climate scientist. We have little time to reverse the trend. (Image) An example of the dangerous pace of change is emerging on Russia's Eastern Siberian Arctic Shelf. Long-frozen permafrost is beginning to melt due to global warming. This threat was identified years ago due to the potential for highly toxic releases of heat-trapping methane gas.  Recent changes are both a surprise and a cause for alarm. There is more methane gas released from the Russian cauldron "than the CH4 emissions estimate for the entire world ocean." Methane is a "far more potent GHG [greenhouse gas] than CO2" with a greater potential to cause "abrupt climate change." At the same time, researchers at the Institute for Atmospheric and Climate Science in Zurich developed a more efficient analysis of contributors to global warming. They found man-made causes can now be linked with at least 75% of global warming. Hansen's warning is brought to life by the methane gas event starting in the Arctic. We are in the danger zone. By the time we know it's too late, it won't matter. Without prompt, concerted action through readily available technologies and programs, we face increasing calamities through midcentury. After that, the displacement, destruction, and death assume unthinkable proportions. As these evidence-based warnings were issued, the military effort to seize effective control of oil and natural gas regions of the Middle East and Central Asia continued unabated. Ironically, as our rulers engage in endless military conflicts to secure access to oil, they are delivering a weapon of mass destruction, an oil-based economy that will create massive disasters and dislocations that plunge the world into chaos.

World Net Daily - $2 trillion sunstorm coming, NASA warns - Recovery time period estimated at 10 years

World Net Daily: December 04, 2011

Editor's Note: The following report is excerpted fromJoseph Farah's G2 Bulletin,the premium online newsletter published by the founder of WND.

WASHINGTON – The U.S. is becoming increasingly aware and concerned about the possibility within a few years of an electromagnetic pulse attack from an enemy's high-altitude nuclear explosion. The impact would include the loss of critical U.S. electrical infrastructure that could send the nation back into an 18th century agrarian economy, according to a report fromJoseph Farah's G2 Bulletin.

But experts have warned that such an attack could produce conditions more difficult than the 18th century due to the considerable increase in population and the total reliance by society on electricity and technology for life-sustaining factors, such as food production and delivery. Also hit would be transportation, medical and emergency services, telecommunications, and the economic and financial system.

Republican presidential candidate and former Speaker of the U.S. House of Representatives Newt Gingrich, in a nationally televised presidential debate, recently declared that the potential for an EMP attack is perhaps the most serious national security threat facing the United States today.
