Response to Gavin Schmidt - Global Climate Data Base Issues Are Real

Gavin Schmidt wrote a hit piece on Tuesday night's the Lou Dobbs show that featured a discussion of global cooling. He objected that he was the sole voice on the side on global warming. He said the piece was not fair and balanced. To Gavin and the other alarmists, it appears, a piece that is fair and balanced can make no mention of any other opinion except that carbon dioxide is causing global warming and action is needed now and will deliver gain and no pain, something the one sided media coverage has gotten them used to over the years.

Yet there is considerable evidence that man is not responsible anything but local climate change through urbanization (the world's population has grown from 1.5 to 6.5 billion people since 1900) and locally and regionally through land use changes like deforestation, forestation and irrigation. Consider for example United States temperatures cooled from the end of WWII in the 1940s to the late 1970s, warmed from 1979 to 1998 then leveled off and fell. That means 5 of the last 7 decades has seen cooling during the most rapid industrialization period, the post WWII boom. CO2 has increased the whole time. This does not give cause to believe CO2 is the primary climate driver as the alarmists want you to believe. We have shown you on this site many examples of how other factors like ENSO, the Pacific Decadal Oscillation, Atlantic Multidecadal Oscillation and cycles on the sun and volcanism are much better correlated with the observed temperatures than CO2 and are the real drivers.

US: Earthquake Rattles Central New Jersey ... Again

For the second time in two weeks, a small earthquake has rattled an area of central New Jersey.

But like the last quake in Morris County, no significant damage or injuries were reported.

Strong quake hits off northern Peru coast

Lima - The U.S. Geological Survey is reporting a strong earthquake off the coast of northern Peru.

The magnitude 6.2 quake shook the region at 5:04 a.m. local time on Sunday (10:04 GMT, 5:04 a.m. EST) about 22 miles (35 kilometers) under the ocean floor.

Earth May Be Home to Unearthly Life

Scientists may not need to explore outer space to find 'alien' biology, cosmologist says.

When ET phones home, he may not have to make a long-distance call.

Forms of life different from the organisms humans are familiar with may exist on this planet already, says cosmologist Paul Davies of Arizona State University in Tempe. At a news conference on February 14 at the annual meeting of American Association for the Advancement of Science, Davies and other scientists interested in identifying alien life-forms called for a "mission to Earth" to discover "life as we don't know it."

Many scientists used to believe that life was statistically improbable. In recent decades that view has shifted, and many now think that life may exist all over the universe. If it is possible to find life on other Earth-like planets, then "weird" or "shadow" life might already exist on Earth, Davies says.

Study: 'Astonishing richness' in polar sea species

Bangkok, Thailand - The polar oceans are not biological deserts after all.

A marine census released Monday documented 7,500 species in the Antarctic and 5,500 in the Arctic, including several hundred that researchers believe could be new to science.

"The textbooks have said there is less diversity at the poles than the tropics, but we found astonishing richness of marine life in the Antarctic and Arctic oceans," said Victoria Wadley, a researcher from the Australian Antarctic Division who took part in the Antarctic survey. "We are rewriting the textbooks."

Amazing Pictures of Color Striped Icebergs in Antarctic

Icebergs in the Antarctic area sometimes have stripes, formed by layers of snow that react to different conditions.

Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that no bubbles form.

When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe.

Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.

Flashback Arctic ice thickness 'plummets'

The thickness of Arctic sea ice "plummeted" last winter, thinning by as much as one-fifth in some regions, satellite data has revealed.

A study by UK researchers showed that the ice thickness had been fairly constant for the previous five winters.

The team from University College London added that the results provided the first definitive proof that the overall volume of Arctic ice was decreasing.

The findings have been published in the journal Geophysical Research Letters.

"The ice thickness was fairly constant for the five winters before this, but it plummeted in the winter after the 2007 minimum," lead author Katharine Giles told BBC News.

Sea ice in the Arctic shrank to its smallest size on record in September 2007, when it extended across an area of just 4.13 million sq km (1.59 million sq miles), beating the previous record low of 5.32 million sq km, measured in 2005.

The team from the university's Centre for Polar Observation and Modelling - part of the UK's National Centre for Earth Observation - found that last winter the ice had thinned by an average of 10% (26cm/0.9ft) below the 2002-2008 winter average.

Dr Giles added that the data also showed the western Arctic experienced the greatest impact, where the ice thinned by up to 19% (49cm/1.6ft).

Flashback Propaganda: Arctic ice meltdown close to 'tipping point'

Arctic ice is melting quicker than predicted and may now be close to a "tipping point" when the changes cannot be reversed, a conservation group has claimed.

Satellite monitoring suggests that the ice has shrunk by more than a third since the late 20th century, and the pace at which both Arctic sea ice and the Greenland ice sheet are melting has "severely accelerated".

This could bring about rapid and unstoppable change in natural systems across the world, according to the WWF.

Flashback Propaganda: Arctic Sea Ice Gone in Summer Within Five Years?

An already relentless melting of the Arctic greatly accelerated this summer - a sign that some scientists worry could mean global warming has passed an ominous tipping point.

One scientist even speculated that summer sea ice could be gone in five years.

Greenland's ice sheet melted nearly 19 billion tons more than the previous high mark, and the volume of Arctic sea ice at summer's end was half what it was just four years ago, according to new NASA satellite data obtained by the Associated Press.

"The Arctic is screaming," said Mark Serreze, senior scientist at the government's snow and ice data center in Boulder, Colorado.

Flashback Propaganda: Environment Summit -Arctic thaw may be at "tipping point"

Oslo - A record melt of Arctic summer sea ice this month may be a sign that global warming is reaching a critical trigger point that could accelerate the northern thaw, some scientists say.

"The reason so much (of the Arctic ice) went suddenly is that it is hitting a tipping point that we have been warning about for the past few years," James Hansen, director of NASA's Goddard Institute for Space Studies, told Reuters.

The Arctic summer sea ice shrank by more than 20 percent below the previous 2005 record low in mid-September to 4.13 million sq km (1.6 million sq miles), according to a 30-year satellite record. It has now frozen out to 4.2 million sq km.

The idea of climate tipping points -- like a see-saw that suddenly flips over when enough weight gets onto one side -- is controversial because it is little understood and dismissed by some as scaremongering about runaway effects.
