ANOTHER PAPER POINTING OUT THAT IT IS GLOBAL WARMING THAT CAUSES AN ATMOSPHERIC CO2 RISE

Not vice versa, as the warmists would have it. Abstract below:

Marine Radiocarbon Evidence for the Mechanism of Deglacial Atmospheric CO2 Rise

By Thomas M. Marchitto et al.

We reconstructed the radiocarbon activity of intermediate waters in the eastern North Pacific over the past 38,000 years. Radiocarbon activity paralleled that of the atmosphere, except during deglaciation, when intermediate-water values fell by more than 300 per mil. Such a large decrease requires a deglacial injection of very old waters from a deep-ocean carbon reservoir that was previously well isolated from the atmosphere. The timing of intermediate-water radiocarbon depletion closely matches that of atmospheric carbon dioxide rise and effectively traces the redistribution of carbon from the deep ocean to the atmosphere during deglaciation.






Global warming as the modern equivalent of "witchcraft" -- It explains everything



Taranto had a good comment on this: "We were wondering just how much global temperatures went up between 2005 and 2006, so we checked with NASA. It turns out the average global temperature actually declined by 0.09 degrees centigrade. Maybe the cats had to go into heat to keep warm."

Droves of cats and kittens are swarming into animal shelters nationwide, and global warming is to blame, according to one pet adoption group. Several shelters operated by a national adoption organization called Pets Across America reported a 30 percent increase in intakes of cats and kittens from 2005 to 2006, and other shelters across the nation have reported similar spikes of stray, owned and feral cats.

The cause of this feline flood is an extended cat breeding season thanks to the world's warming temperatures, according to the group, which is one of the country's oldest and largest animal welfare organizations. "Cats are typically warm-weather, spring-time breeders," said the group's president, Kathy Warnick. "However, states that typically experience primarily longer and colder winters are now seeing shorter, warmer winters, leading to year-round breeding." "Basically, there is no longer a reproduction lull with cat breeding cycles, and unfortunately, it seems more people are bringing boxes of kittens into our agencies during winter now," she added. Studies have shown that global warming is altering the breeding seasons of other animals, such as migratory birds and penguins.

One possible solution to stem the tide of cats is to make sure pets are spayed or neutered. "We have long discussed the benefits of spaying and neutering cats," said Pets Across America Vice President Bob Rhode. "It is likely that global warming is probably not going to be slowing any time soon, therefore, it benefits everyone when pet owners take action and spay and neuter their pets."

Dirty snow may warm Arctic as much as greenhouse gases

Another finding of "not guilty" for the carbon dioxide "witch". But this COULD lead to a war on soot -- but that might actually be beneficial so don't hold your breath

The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases. Snow becomes dirty when soot from tailpipes, smoke stacks and forest fires enters the atmosphere and falls to the ground. Soot-infused snow is darker than natural snow. Dark surfaces absorb sunlight and cause warming, while bright surfaces reflect heat back into space and cause cooling. "When we inject dirty particles into the atmosphere and they fall onto snow, the net effect is we warm the polar latitudes," said Charlie Zender, associate professor of Earth system science at UCI and co-author of the study. "Dark soot can heat up quickly. It's like placing tiny toaster ovens into the snow pack." The study appears this week in the Journal of Geophysical Research.

Dirty snow has had a significant impact on climate warming since the Industrial Revolution. In the past 200 years, the Earth has warmed about .8 degree Celsius [Less than one degree! What a calamity!]. Zender, graduate student Mark Flanner, and their colleagues calculated that dirty snow caused the Earth's temperature to rise .1 to .15 degree, or up to 19 percent of the total warming. In the past two centuries, the Arctic has warmed about 1.6 degrees. Dirty snow caused .5 to 1.5 degrees of warming, or up to 94 percent of the observed change, the scientists determined.

The amount of warming by dirty snow varied from year to year, with higher temperatures in years with many forest fires. Greenhouse gases, which trap outgoing energy, are primarily responsible for the remaining temperature increase and are considered the Earth's most important overall climate changing mechanism. Other human influences on Arctic climate change are particles in the atmosphere, including soot; clouds; and land use. Humans create the majority of airborne soot through industry and fuel combustion, while forest and open-field fires account for the rest. Because of human activity, greenhouse gas levels have increased by one-third in the last two centuries. "A one-third change in concentration is huge, yet the Earth has only warmed about .8 degrees because the effect is distributed globally," Zender said. "A small amount of snow impurities in the Arctic have caused a significant temperature response there."

Previous studies have analyzed dirty snow's effect on climate, but this is the first to take into account realistic emissions from forest fires in the Northern Hemisphere and how warming affects the thickness of the snow pack. In some polar areas, impurities in the snow have caused enough melting to expose underlying sea ice or soil that is significantly darker than the snow. The darker surfaces absorb sunlight more rapidly than snow, causing additional warming. This cycle causes temperatures in the polar regions to rise as much as 3 degrees Celsius during some seasons, the scientists say. "Once the snow is gone, the soot that caused the snow to melt continues to have an effect because the ground surface is darker and retains more heat," Zender said. Dirty snow is prevalent in East Asia, Northern Europe and Northeastern United States.

Zender believes policymakers could use these research results to develop regulations to mitigate global warming. Limiting industrial soot emissions and switching to cleaner-burning fuels would leave snow brighter, he says. New snow falls each year, and if it contained fewer impurities, the ground would brighten and temperatures would cool. Carbon dioxide lives in the atmosphere for a century, so cutting back on emissions can prevent further warming but does not produce immediate cooling.

Hurricane frequency fluctuates naturally

Hurricanes in the Atlantic are increasing because of natural weather patterns rather than global warming, a study has concluded. Growing numbers of hurricanes battering the United States and the Caribbean have made their presence felt in the past decade and are forecast to worsen. Global warming has been cited as a possible cause but researchers looking at sediment and coral deposits have now identified natural variations in their frequency. Hurricane Katrina, which devastated New Orleans in 2005, was "unexceptional" when historic patterns of such stormy weather are analysed, they suggested.

Global warming may even have been responsible for unusually low levels of hurricanes in the 25 years before 1995 when the number began rising, according to the scientists, led by the Geological Survey of Sweden. Using deposits trapped in sediment to indicate when hurricanes had taken place, the researchers built up a record detailing their number and frequency going back 270 years. They found that the decline in hurricanes during the 1970s and 1980s was matched by similar declines in the past, indicating natural variations in the weather patterns. "The record indicates that the average frequency of major hurricanes decreased gradually from the 1760s until the early 1960s, reaching anomalously low values during the 1970s and 1980s," they reported in the journal Nature. "Furthermore, the phase of enhanced hurricane activity since 1995 is not unusual compared to other periods of high hurricane activity and appears to represent a recovery to normal hurricane activity."

The findings are at variance with the conclusions in February of the Intergovernmental Panel on Climate Change, the United Nations organisation addressing global warming. The UN panel stopped short of blaming increased frequency of hurricanes on man-made temperature rises, but said it was "more likely than not" that greenhouse gas emissions had contributed to the greater intensity of cyclonic storms.

The Swedish-led research team suggested that hurricane levels were normal, though they accepted "a future possibility" of higher sea temperatures contributing to more intense hurricanes.The researchers were unable to identify any direct link between increased hurricanes and rising sea level temperatures, beyond the requirement for a minimum temperature of 27C (81F) to be reached before a hurricane developed. From 1730-2005 there were on average 3-3.5 major hurricanes each year.

The researchers from Sweden, the US and Puerto Rico said that being able to calculate vertical wind shear - the differences in wind speeds at different heights - was crucial in determining the frequency of hurricanes. Higher wind-shear levels disrupt developing hurricanes; low wind-shear levels fail to batter the storms sufficiently to prevent them developing. The researchers suggested that higher air temperatures caused by global warming may have led to stronger vertical wind shear, which has destroyed developing hurricanes in the Atlantic before 1995, explaining the dearth.

Deposits of sediments accumulated from increased run-off from rainfall and plankton remains associated with increased levels of nutrients and provided clues to the scientists to historic vertical wind shear and hurricanes. They were able to check their readings of the data by comparing their findings with documentation of hurricanes.

In the wind

-- From 1995 to 2005 there were an average of 4.1 major hurricanes (categories 3-5) in the Atlantic compared with an average of 1.5 from 1971-94

-- Five periods in the past 270 years were found to have had the same lack of hurricanes, combined with high wind shear, as 1971-94: 1730-36, 1793-99, 1827-30, 1852-66 and 1915-26

-- Six periods were identified as having the same high levels witnessed since 1995: 1756-74, 1780-85, 1801-12, 1840-50, 1873-90 and 1928-33

G8 LEADERS 'AGREE CLIMATE DEAL'

Hot air to deal with hot air seems appropriate



Leaders of the G8 nations have agreed to a compromise deal on tackling climate change, German Chancellor Angela Merkel has said. "We agreed... that CO2 emissions must first be stopped and then followed by substantial reductions," she said. Reports said the leaders had agreed to hold talks on a replacement to the Kyoto Protocol within a UN framework. Mrs Merkel had been pushing for a 50% cut in emissions by 2050. The US had resisted calls for targets to be fixed. She said G8 leaders had agreed to consider her target, but there was no suggestion that a final agreement would include any mandatory commitment to major emissions cuts.

According to an extract from the agreed text published on the G8 website, the leaders agreed to take "strong and early" action. "Taking into account the scientific knowledge as represented in the recent IPCC [Intergovernmental Panel on Climate Change] reports, global greenhouse gas emissions must stop rising, followed by substantial global emission reductions," the text says.

The BBC's Steve Rosenberg, in Heiligendamm, says the German chancellor has portrayed the deal as a major success. The compromise appears to bring Mr Bush's plan into the wider UN-brokered process - something the US had previously resisted.

NOTE FROM BENNY PEISER ON THE ABOVE:

The compromise at the G8 climate summit appears to be based on the US-and Canadian-backed climate plan presented by Japanese Prime Minister Shinzo Abe The G8 has essentially agreed that any effective international framework on climate change must include China, India and other major greenhouse gas emitters from the developing world.

More importantly, by offering a deal to cut global CO2 emissions by half, not just those of a handful of richer nations, the G8 has shifted international pressure away from the West and onto China and India.

The BBC claim that "the compromise appears to bring Mr Bush's plan into the wider UN-brokered process - something the US had previously resisted" is a bit of a red herring as Bush's own climate initiative doesn't see itself outside the UNFCCC framework: "Under The President's Proposal, The United States Will Convene The Major Emitters And Energy Consumers To Advance And Complete The New Framework By The End Of 2008. The U.S. remains committed to the UN Framework Convention on Climate Change, and we expect the new framework to complement ongoing UN activity...."

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is generally to promote themselves as wiser and better than everyone else, truth regardless.

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists
