Solar Flares to Continue Pounding Earth Until 2014
The wave of solar storms that has pounded Earth over the past several weeks is only likely to get worse over the next year, according to a NASA scientist.
Sunspot 1429, the active region of the sun responsible for the flares, has been getting larger over the past several weeks, making it less stable and more likely for additional flares to erupt, which can cause damage to GPS satellites and electronic systems on our planet. NASA reported that the sunspot is now more than seven times the width of earth.
“The larger [the active region] is, the more likely it’s going to produce another big flare,” Phillip Chamberlin, deputy project scientist for the Solar Dynamics Observatory says. “It’s growing, and it’s becoming more dynamic, building energy.”
Over the weekend, two large flares erupted from the region. NASA says the wind and energy particles associated with the flare, began to affect Earth Monday. The region is dangerous for Read more…
China Ups Military Spending
China’s announcement of a more than 11 percent increase in declared military spending, following two full decades of double-digit increases, raises several uncomfortable questions for Asia and the West. It’s natural for a rising power like China to develop capabilities to defend its expanding array of interests. On the other hand, China’s ascent has been made possible by a benign security environment that well served China’s goal of “peaceful development.” China’s growing military capabilities now threaten to upset that order in ways that, ironically, could complicate China’s security environment at the same time as slowing economic growth intensifies its internal challenges.China’s defense spending – now officially $106 billion but estimated by the Pentagon and independent researchers to be more than $160 billion – is on track to exceed that of all its Asian neighbors combined within a few years. This is particularly striking in light of a wider Asian arms race: India is the world’s Read more…
Greenland ice sheet may melt completely with 1.6 degrees global warming

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius of global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees of global warming has been observed. Substantial melting of land ice could contribute to long-term sea-level rise of several meters and therefore it potentially affects the lives of many millions of people. The time it takes before Read more…
North Korean Nuclear Work Poses Greater Threat Than Iran, Amano Says
International Atomic Energy Agency Director General Yukiya Amano on Saturday said he believes the threat posed by Iran’s atomic activities is eclipsed by the dangers of North Korea’s known nuclear-weapon efforts, Kyodo News reported (see GSN, March 9).
The North’s development of nuclear weapons, which includes two nuclear tests to date, is a “threat to East Asia,” the head of the U.N. nuclear watchdog said.
“The problem (with North Korea) is serious and its impact on the world is larger” than Iran, Amano said. His organization and a number of governments around the world worry that Iran is seeking a nuclear-weapon capability; Tehran maintains that its atomic development program is strictly peaceful (see related GSN story, today).
The veteran Japanese diplomat said he hopes to dispatch IAEA monitors to North Korea to verify implementation of a recently agreed-to shutdown of Read more…
Solar storm headed toward Earth may disrupt power
WASHINGTON (AP) — The largest solar flare in five years is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and airplane flights.
The sun erupted Tuesday evening, and the effects should start smacking Earth around 7 a.m. EST Thursday, according to forecasters at the federal government’s Space Weather Prediction Center. They say the flare is growing as it speeds outward from the sun.
“It’s hitting us right in the nose,” said Joe Kunches, a scientist for the National Oceanic and Atmospheric Administration. He called it the sun’s version of “Super Read more…
And there shall be signs in the Sun, Moon, and Stars – 2012
Luke 12:56 (KJV) Ye hypocrites, ye can discern the face of the sky and of the earth; but how is it that ye do not discern this time?
MATTHEW 24-8 (KJV) All these are the beginning of sorrows.
Repent of your sins and come to Christ, the Kingdom of God is near!!!
Oldest and thickest Arctic sea ice is disappearing
A new study by NASA scientist Joey Comiso has found that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the ice cap. The rapid disappearance of older ice makes the Arctic Ocean’s sea ice cap more vulnerable to further decline.
Arctic multi-year ice “extent”—which includes all areas where at least 15 percent of the ocean surface is covered by multi-year ice—has been vanishing at a rate of –15.1 percent per decade, Comiso found. Over the same period, the “area” covered by multi-year ice—which discards open water among ice floes and focuses exclusively on regions that are completely covered—has been shrinking by –17.2 percent per decade. The findings were Read more…
