Al Gore is an idiot

A new study out of Germany casts further doubt on the so-called global warming “consensus” by suggesting the atmosphere may be less sensitive to increases in carbon dioxide emissions than most scientists think.

A study by scientists at Germany’s Max Planck Institute for Meteorology found that man-made aerosols had a much smaller cooling effect on the atmosphere during the 20th Century than was previously thought. Why is this big news? It means increases in carbon dioxide emissions likely cause less warming than most climate models suggest.

What do aerosols have to do with anything? Well, aerosols are created from human activities like burning coal, driving cars or from fires. There are also natural aerosols like clouds and fog. Aerosols tend toreflect solar energy back into space, giving them a cooling effect that somewhat offsets warming from increased CO2 emissions.

The Max Planck study suggests “that aerosol radiative forcing is less negative and more certain than is commonly believed.” In layman’s terms, aerosols are offsetting less global warming than was previously thought. And if aerosols aren’t causing as much cooling, it must mean carbon dioxide must be causing less warming than climate models predict.

“Going forward we should expect less warming from future greenhouse gas emissions than climate models are projecting,” write climate scientists Pat Michaels and Chip Knappenberger with the libertarian Cato Institute, adding that this study could be a “death blow” to global warming hysteria.

Independent climate researcher Nick Lewis put out a study last year with Georgia Tech’s Dr. Judith Curry that found that the climate’s response to a doubling of atmospheric CO2 levels — a measurement called “climate sensitivity” was 1.64 degrees Celsius.

Lewis revised his findings based on the Max Planck aerosol study and found something astounding: climate sensitivity drops dramatically. Lewis also looked at climate sensitivity estimates given by the Intergovernmental Panel on Climate Change — often regarded as the world’s top authority on global warming.

The IPCC’s latest assessment put climate sensitivity between 1.5 and 4.5 degrees Celsius. The IPCC says that despite “the large uncertainty range, there is a high confidence that aerosols have offset a substantial portion of [greenhouse gas] global mean forcing.”

Basically, the IPCC says aerosols deflect a lot of warming — the opposite of the Max Planck study’s finding.

But incorporating the results from the Max Planck study dramatically reduces the upper bound estimate of climate sensitivity from 4.5 degrees to 1.8 degrees Celsius.

To put this into perspective, atmospheric concentrations of CO2 currently stand at around 400 parts per million, if this were to double, according to the IPCC’s estimates temperatures could rise as high as 4.5 degrees Celsius.

But incorporate the Max Planck study results and warming would only be as high as 1.8 degrees Celsius — less than half what the IPCC originally predicted.

Michaels and Knappenberger say Lewis’s findings basically eliminate “the possibility of catastrophic climate change—that is, climate change that proceeds at a rate that exceeds our ability to keep up.”

“Such a result will also necessarily drive down estimates of social cost of carbon thereby undermining a key argument use by federal agencies to support increasingly burdensome regulations which seek to reduce greenhouse gas emissions,” write Michaels and Knappenberger.

BOGUS CLIMATE CHANGE EXCUSE FOR ONE WORLD ORDER..

Falling Sea Level Upsets Theory of Global Warming
By Mark Chipperfield in Tuvalu and David Harrison in London Article from The Telegraph
6 August 2000


In the early 1990s, scientists forecast that the coral atoll of nine islands - which is only 12ft above sea level at its highest point - would vanish within decades because the sea was rising by up to 1.5in a year. However, a new study has found that sea levels have since fallen by nearly 2.5in and experts at Tuvalu's Meteorological Service in Funafuti, the islands' administrative centre, said this meant they would survive for another 100 years.
They said similar sea level falls had been recorded in Nauru and the Solomon Islands, which were also considered to be under threat. The release of the data from Tuvalu, formerly part of the Gilbert and Ellice Islands, will renew scientific debate about climate change and its impact on ocean levels. The island's scientists admitted they were surprised and "a little embarrassed" by the change, which they blame on unusual weather conditions caused by El Nino in 1997.

Hilia Vavae, the Metereological Service's director, said: "This is certainly a bit of a shock for us because we have been experiencing the effect of rising oceans for a long time." Although their country has been saved from imminent engulfment, not all islanders are happy about the change in Tuvalu's fortunes. Residents who once worried about their homes being flooded are now complaining that the lower tides are disrupting their fishing expeditions, making it difficult to moor their boats and navigate low-lying reefs. 




All the hype about human caused climate change is disinformation to force you into the One World Order where you will be living in a smaller house or yurt, have fewer children, drive a smaller car and burn oil forever.


They want to keep us on this planet as energy slaves using false propaganda. Sea levels in Cook Inlet, Kodiak have been dropping 3-feet in 100 years--this according to NOAA's actual tide measurement stations. Below is another article on lower sea levels.

Oceans to fall over thousands of years not rise.

By Alister Doyle, Environment Correspondent

OSLO | Thu Mar 6, 2008 2:06pm EST

OSLO (Reuters) - Sea levels are set to fall over millions of years, making the current rise blamed on climate change a brief interruption of an ancient geological trend, scientists said on Thursday.

They said oceans were getting deeper and sea levels had fallen by about 170 meters (560 ft) since the Cretaceous period 80 million years ago when dinosaurs lived. Previously, the little-understood fall had been estimated at 40 to 250 meters.
"The ocean floor has got on average older and gone down and so the sea level has also fallen," said Bernhard Steinberger at the Geological Survey of Norway, one of five authors of a report in the journal Science.
"The trend will continue," he told Reuters.
A computer model based on improved understanding of shifts of continent-sized tectonic plates in the earth's crust projects more deepening of the ocean floor and a further sea level decline of 120 meters in 80 million years' time.
If sea levels were to fall that much now, Russia would be connected to Alaska by land over what is now the Bering Strait, Britain would be part of mainland Europe and Australia and Papua island would be the same landmass.
The study aids understanding of sea levels by showing that geology has played a big role alongside ice ages, which can suck vast amounts of water from the oceans onto land.
DOWN NOT UP
"If we humans still exist in 10, 20 or 50 million years, irrespective of how ice caps are waxing and waning, the long term ... is that sea level will drop, not rise," said lead author Dietmar Muller of the University of Sydney.
Over time, Muller told Science in a podcast interview there would be fewer mid-ocean ridges and a shift to more deep plains in the oceans as continents shifted. The Atlantic would widen and the Pacific shrink.
Still, the projected rate of fall works out at 0.015 centimeters a century -- irrelevant when the U.N. Climate Panel estimates that seas will rise by 18-59 cms by 2100 because of global warming stoked by human use of fossil fuels.
"Compared to what is expected due to climate change, the fall is negligible," said Steinberger. Cities from Miami to Shanghai are threatened by rising seas that could also swamp low-lying island nations in the Pacific.
Rising temperatures raise sea levels because water in the oceans expands as it warms, and many glaciers are melting into the seas.
Antarctica and Greenland now contain enough ice to raise sea levels by 50 meters if they all melted, the article said. If all ice on land were gone in 80 million years' time, the net drop in ocean levels would be 70 meters rather than the projected 120.
The study challenges past belief that sea levels might have been only 40 meters higher than today in the Cretaceous period by arguing that measurements from New Jersey in the United States had underestimated the fall.
It said that the New Jersey region had itself subsided by 105 to 180 meters in the period, skewing the readings.
