CLIMATE, CLIMATE, CLIMATE

It's the big debate in Australia at the moment. Four current articles up today on AUSTRALIAN POLITICS, including two slash-and-burn articles on the nonsense by Australian scientists.





Global cooling!

Penguins wash up in the tropics



PENGUINS are washing up on tropical beaches with scientists unsure why the Antarctic birds are heading closer to the equator than ever before. About 300 penguins have recently been found dead and alive along the coast of the Brazil' s Bahia state, 1200km northeast of Rio de Janeiro, the Associated Press reports. The area is more renowned as a place to get a tan than it is to spot penguins. Its capital Salvador is closer to the equator than Cairns in northern Queensland and its temperature has hovered around 20 degrees Celsius this month.

"This is unheard of. There have even been reports of penguins washing up as far as Aracaju,'' Adelson Cerqueira Silva of Brazil's environmental agency said, referring to a beachside state capital even closer to the equator.

Mr Silva said biologists believe stronger-than-usual ocean currents had pulled the birds north but others have said overfishing and warmer ocean temperatures may have led the birds to search for food further north than their normal Antarctic and Patagonian habitats. Authorities had received hundreds of penguin sightings, he said. "We're telling people if the penguins don't appear to be injured or sick to leave them alone so they can swim back," he said. Up to 90 of the penguins found alive had since died in animal hospitals struggling to deal with the influx.

Another IPCC & Hansen FAILURE: Bangladesh gaining land, not losing it

Contradicting forecasts it will be 'under the waves by the end of the century'. Name anything that James Hansen PhD, has predicted correctly.

New data shows that Bangladesh's landmass is increasing, contradicting forecasts that the South Asian nation will be under the waves by the end of the century, experts say. Scientists from the Dhaka-based Center for Environment and Geographic Information Services (CEGIS) have studied 32 years of satellite images and say Bangladesh's landmass has increased by 20 square kilometres (eight square miles) annually.

Maminul Haque Sarker, head of the department at the government-owned centre that looks at boundary changes, told AFP sediment which travelled down the big Himalayan rivers -- the Ganges and the Brahmaputra -- had caused the landmass to increase.The rivers, which meet in the centre of Bangladesh, carry more than a billion tonnes of sediment every year and most of it comes to rest on the southern coastline of the country in the Bay of Bengal where new territory is forming, he said in an interview on Tuesday.

The United Nations Intergovernmental Panel on Climate Change (IPCC) has predicted that impoverished Bangladesh, criss-crossed by a network of more than 200 rivers, will lose 17 percent of its land by 2050 because of rising sea levels due to global warming. The Nobel Peace Prize-winning panel says 20 million Bangladeshis will become environmental refugees by 2050 and the country will lose some 30 percent of its food production. Director of the US-based NASA Goddard Institute for Space Studies, professor James Hansen, paints an even grimmer picture, predicting the entire country could be under water by the end of the century.

But Sarker said that while rising sea levels and river erosion were both claiming land in Bangladesh, many climate experts had failed to take into account new land being formed from the river sediment."Satellite images dating back to 1973 and old maps earlier than that show some 1,000 square kilometres of land have risen from the sea," Sarker said."A rise in sea level will offset this and slow the gains made by new territories, but there will still be an increase in land. We think that in the next 50 years we may get another 1,000 square kilometres of land."

Mahfuzur Rahman, head of Bangladesh Water Development Board's Coastal Study and Survey Department, has also been analysing the buildup of land on the coast.He told AFP findings by the IPCC and other climate change scientists were too general and did not explore the benefits of land accretion."For almost a decade we have heard experts saying Bangladesh will be under water, but so far our data has shown nothing like this," he said. "Natural accretion has been going on here for hundreds of years along the estuaries and all our models show it will go on for decades or centuries into the future."

Dams built along the country's southern coast in the 1950s and 1960s had helped reclaim a lot of land and he believed with the use of new technology, Bangladesh could speed up the accretion process, he said."The land Bangladesh has lost so far has been caused by river erosion, which has always happened in this country. Natural accretion due to sedimentation and dams have more than compensated this loss," Rahman said.

Bangladesh, a country of 140 million people, has built a series of dykes to prevent flooding."If we build more dams using superior technology, we may be able to reclaim 4,000 to 5,000 square kilometres in the near future," Rahman said.

Scientist on Greenland: 'Greenland was about as warm or warmer in the 1930's and 40's'?

The New York Times Magazine published a story "Ice Free" by Stephan Faris, hawking his new book "Forecast: The Consequences of Climate Change, From the Amazon to the Arctic, From Darfur to Napa Valley", to be published in January.

In the article, Faris notes "Greenland's ice sheet represents one of global warming's most disturbing threats. The vast expanses of glaciers- massed, on average, 1.6 miles deep - contain enough water to raise sea levels worldwide by 23 feet. Should they melt or otherwise slip into the ocean, they would flood coastal capitals, submerge tropical islands and generally redraw the world's atlases. The infusion of fresh water could slow or shut down the ocean's currents, plunging Europe into bitter winter."

There is little recognition in the media and by the author of history. Greenland actually was warmer in the 1930s and 1940s than it has been in recent decades. For the period from the 1960s to the 1990s, temperatures actually declined significantly as the Atlantic went through its multidecadal cold mode. The temperature changes up and down the last few centuries were closely related to these multidecadal ocean cycles.

Shown below is the temperature plot for Godthab Nuuk in southwest Greenland. Note how closely the temperatures track with the AMO (which is a measure of the Atlantic temperatures 0 to 70N). It shows that cooling from the 1940s to the late 1990s even as greenhouse gases rose steadily, a negative correlation over almost 5 decades. The rise after the middle 1990s was due to the flip of the AMO into its warm phase. They have not reached the level of the 1930s and 1940s.

Temperatures cooled back to the levels of the 1880s by the 1980s and 1990s. In a GRL paper in 2003, Hanna and Cappelen showed a significant cooling trend for eight stations in coastal southern Greenland from 1958 to 2001 (-1.29§C for the 44 years). The temperature trend represented a strong negative correlation with increasing CO2 levels.

Many recent studies have addressed Greenland ice mass balance. They yield a broad picture of slight inland thickening and strong near-coastal thinning, primarily in the south along fast-moving outlet glaciers. However, interannual variability is very large, driven mainly by variability in summer melting and sudden glacier accelerations. Consequently, the short time interval covered by instrumental data is of concern in separating fluctuations from trends. But in a paper published in Science in February 2007, Dr. Ian Howat of the University of Washington reports that two of the largest glaciers have suddenly slowed, bringing the rate of melting last year down to near the previous rate. At one glacier, Kangerdlugssuaq, "average thinning over the glacier during the summer of 2006 declined to near zero, with some apparent thickening in areas on the main trunk."

Dr. Howat in a follow-up interview with the New York Times went on to add: "Greenland was about as warm or warmer in the 1930's and 40's, and many of the glaciers were smaller than they are now. This was a period of rapid glacier shrinkage world-wide, followed by at least partial re-expansion during a colder period from the 1950's to the 1980's. Of course, we don't know very much about how the glacier dynamics changed then because we didn't have satellites to observe it. However, it does suggest that large variations in ice sheet dynamics can occur from natural climate variability."

Greenland's "melting" ice sheets "will raise sea level 23 feet"

Monckton replies

The scare: An article in the New York Times in late July 2008 by an author promoting a forthcoming book about "global warming" calls the Greenland ice-sheet "one of `global warming's' most disturbing threats". The article says: "The vast expanses of glaciers - massed, on average, 1.6 miles deep - contain enough water to raise sea levels worldwide by 23 feet. Should they melt or otherwise slip into the ocean, they would flood coastal capitals, submerge tropical islands and generally redraw the world's atlases. The infusion of fresh water could slow or shut down the ocean's currents, plunging Europe into bitter winter."

The article continues that ocean warming eats the ice sheet from beneath, causing glaciers to calve and melt faster, changing patterns of migration and hence of hunting, which, it says, has a positive effect: warm-water cod have returned, and shops can now offer locally-grown vegetables. Recession of ice along the shore has exposed pockets of lead, zinc, and bauxite. More than 30 billion barrels of oil may also be reachable if there is further melting. Yet the thrust of the article is Apocalyptic.

The truth: The "Greenland is melting" scare is an old one, and long discredited. It was first given widespread currency by Al Gore, not a climatologist, in his sci-fi comedy horror movie about the climate - a movie that is now an international joke for serious, serial, scientific inaccuracy. In October 2007, a UK High Court Judge ordered the Department of Education to issue a disclaimer about several inaccuracies in the movie before innocent schoolchildren could be exposed to it. The learned Judge's finding about Gore's claim that sea level would imminently rise by 20 ft was blunt:

"This is distinctly alarmist and part of Mr. Gore's `wake-up call'. It is common ground that if Greenland melted it would release this amount of water, but only after, and over, millennia, so that the Armageddon scenario he depicts is not based on any scientific view."

The UN's climate panel, the IPCC, also fueled the scare when its bureaucrats, after the scientists had submitted the final draft of its 2007 report, inserted a table that had not been in the scientists' draft, in which they had ingeniously right-shifted four decimal points so as to exaggerate tenfold the supposed contribution of melting ice-sheets and glaciers to sea-level rise:

Metres per century 1961-2003 1993-2003

1. Thermosteric expansion 0.042 0.160 2. Glaciers and ice-caps 0.050 0.077 3. Greenland ice-sheets 0.050 0.210 4. Antarctic ice-sheets 0.140 0.210

5. IPCC's sum of lines 1-4: 0.110 0.280

The Viscount Monckton of Brenchley earned his share of the Nobel Peace Prize by writing to the IPCC on the morning of publication, demanding - and getting - a correction of this maladroit and unscientific attempt to lend support to the unscientific fantasies of Gore.

Gore's movie said -

Gore: "Two canaries in the coal mine. The first one is in the Arctic. Of course the Arctic Ocean has a floating ice cap, Greenland on its side there. I say canary in the coal mine because the Arctic is one part of the world that is experiencing faster impact from global warming. This is the largest ice shelf in the Arctic, the Ward Hunt Ice Shelf. It just cracked in half a year ago. The scientists were astonished."

But what do the scientific studies and the peer-reviewed scientific literature (as opposed to the layman Gore or the error-prone IPCC) have to say about Greenland, and about sea level generally?

Temperature records show that the Arctic was in fact warmer in the 1930s and 1940s than it is today -

Northern Hemisphere snow cover reached a new record in 2001 -

A new record in 2001 for Northern Hemisphere winter snow cover

But this new record was easily surpassed in 2007, when, for the first time since satellite records began 30 years ago, winter sea ice extent at both Poles reached record highs. Somehow most of the media that had mentioned the record loss of summer sea-ice in the Arctic in 2007 failed to mention the record growth of winter sea ice at both Poles that very winter.

The ice cap at the North Pole has certainly been thinning ever since US nuclear submarines took the first measurements in the 1950s. However, a paper by NASA scientists last year says the reason has nothing to do with "global warming". The warmer Arctic has been caused by the current warming phase of the Atlantic Multidecadal Oscillation, driving warm tropical waters poleward and also causing winds to take a more southerly direction.

Also, a very recent paper has shown considerable and hitherto-unsuspected undersea volcanic activity at 73 degrees North latitude on the mid-Atlantic ridge in the Greenland-Iceland gap, with temperatures at the outlets of the volcanic vents at 570 degrees F.

Among the many facts that the article in the New York Times is careful not to mention is one central fact: that in the early 1940s it was warmer in the Arctic than it is today.

Chylek et al. (2004) confirm that temperatures along Greenland's coasts are about 1 degree Celsius below their 1940 levels, despite half a century of "global warming". They say -

"Current coastal temperatures are about 1øC below their 1940 values." Furthermore, "at the summit of the Greenland ice sheet the summer average temperature has decreased at the rate of 2.2øC per decade since the beginning of the measurements in 1987." Ocean currents and volcanic activity are not the only natural influences on Arctic temperatures. The apparently random fluctuations in Arctic temperatures in the past 125 years are more closely correlated with changes in solar activity than with the ever-upward increases in atmospheric CO2 concentrations. It is scientifically perverse to make an unqualified attribution of the observed thinning of the Arctic ice-cap to anthropogenic "global warming" when, compared with the early 20th century, the Arctic has been cooling. One story that did not make it into the New York Times article - sealers were trapped in Arctic ice in April 2007

Global warming to disrupt sex among fish!

They must have had a hell of a time of it in past warming episodes!

Once scientists began studying the impact of global warming on everything from tourism to asthma, it was only a matter of time before they got around to sex. Now two biologists at Spain's Higher Council for Scientific Research (CSIC) have done just that, at least when it comes to fish.

You may have missed it in biology class, but in some finned species, like the Atlantic silverside - as well as in many reptiles - sex is determined not by genetics but by temperature: the undifferentiated embryo develops testes or ovaries on the basis of whichever option conveys evolutionary advantages for that particular environment. Now, in a study published in the July 30 edition of the scientific journal Public Library of Science, Natalia Ospina-Alvarez and Francesc Piferrer have gone a little further in explaining how that mechanism works. In laboratory tests, they have demonstrated that higher water temperatures result in more male fish.

"We found that in fish that do have temperature-dependent sex determination [TSD], a rise in water temperature of just 1.5 degrees Celsius can change the male-to-female ratio from 1:1 to 3:1," says Piferrer, the study's co-author. In especially sensitive fish, a greater increase can throw the balance even more out of whack. Ospina-Alvarez and Piferrer have found that in the South American pejerrey, for example, an increase of 4 degrees Celsius can result in a population that is 98% male.

What makes these findings especially troubling, of course, is that the International Panel on Climate Change (IPCC) predicts that ocean-water temperatures are likely to rise by 1.5 degrees over the course of this century - and they may even go up a few degrees more. "If climate change really does result in a rise of 4 degrees, which is the maximum the IPCC predicts, and if species can't adapt in time or migrate, then in the most sensitive cases of TSD, we're looking at extinction," says Piferrer.

Most research into fish sex determination has been done in the lab (for obvious reasons), but the pejerrey is one of the few species that scientists have been able to study in the field. And those studies have revealed that already, its proportion of males to females is skewed. "It could be because of chemical pollution or it could be because of climate change. We don't know," cautions Piferrer. "But the field data matches our predictions."

At this stage, it is hard to tell what these results bode for already declining fish populations around the world. Of the estimated 33,000 piscatorial species, only 5,000 have had their sex-determination mechanism affirmed. But the study by the two CSIC scientists also suggests that the percentage of TSD fish is lower than previously believed. In tests of 59 species believed to be reproductively sensitive to temperature, only 40 proved to be true TSDs.

The Greens Are Going Crazy

It's hard to ignore the fact that the Greens are going crazy, not just in the United States, but around the world. They are increasingly frantic over the opposition being voiced against global warming, one of the greatest hoaxes in modern history. The Greens have bet everything on global warming as the reason for giving up the use of long established sources of energy such as oil, coal and natural gas. The object has been to slow everything the modern world calls progress.

In India, a spokesman for that nation of one billion people has flatly refused to accept the global warming hoax. China shows no sign of yielding to the global warming lies. The greatest agricultural and mercantile economy to have ever existed, the United States of America continues to thwart its own growth by yielding to the lies.

Recently the Senate Majority Leader, Harry Reid, said that "coal makes us sick. Oil makes us sick. It's global warming. It's ruining our country. It's ruining our world." No, what makes us sick is listening to such preposterous lies. A Rasmussen telephone survey taken after Sen. Reid's absurd statement found that 52% of voters surveyed rejected his views about coal and oil, double the amount of those who agreed.

What is troublesome, however, is that the same survey found the voters evenly divided on whether global warming exists or poses a threat. Fully 47% of those surveyed believe that human activity affects the climate. Both candidates for President are publicly committed to the global warming hoax by varying degrees.

Despite an intense, decades-long propaganda campaign, coupled with indoctrination in our nation's schools, the truth is beginning to emerge. In March, an international conference on climate change organized by The Heartland Institute brought together over 500 of the world's leading climatologists, meteorologists, economists and others for three days of seminars and presentations that completely refuted the pronouncements of the United Nation's Intergovernmental Panel on Climate Change and disputed the lies of Al Gore's famed "documentary."

As recently as July 8th, the Space and Science Research Center held a news conference in which it stated that the warming that has occurred since the end of the Little Ice Age in 1850 was completely natural, i.e., had nothing to do with human or industrial activity. More significantly, the Center went on record saying that, "After an exhaustive review of a substantial body of climate research, and in conjunction with the obvious and compelling new evidence that exists, it is time that the world community acknowledges that the Earth has begun the next climate change." The current warming period is not only at an end, but a distinct cooling cycle has begun and will bring "predominantly colder global temperatures for many years into the future."

Just how crazed has the environmental movement become? On July 7th it was announced that Argentine scientists have been strapping plastic tanks to the backs of cows to collect and measure how much methane gas they produce. Methane, like carbon dioxide, is a minor component of the Earth's atmosphere. Methane is also released from swamps, landfills and other sources. If it and CO2 played a significant role in determining the world's climate, it would be a cause for concern, but it is the Sun that primarily drives the Earth's climate cycles. Solar activity has gone quiet in recent years as fewer and fewer sunspots, magnetic storms, have been seen.

To maintain the global warming hoax, thousands of events and natural phenomena have been blamed on it. A recent example is the floods in America's mid-West. The National Wildlife Federation released a statement on July 1st blaming global warming.

Climate experts at The Heartland Institute were quick to respond. Dr. Joseph D'Aleo, Executive Director of the International Climate and Environmental Change Assessment Project, said, "Alarmists have adopted the can't-lose position that all extremes of weather - cold, warm, wet, or dry - are all due to global warming", adding that, "The record snows, severe weather, and heavy rainfall have been the result of rapid cooling in the northern tier of the United States and Canada, not global warming."

Early in July, Bret Stephens, writing in The Wall Street Journal, called global warming "a mass hysteria phenomenon", noting that "NASA now begrudgingly confirms that the hottest year on record in the continental 48 was not 1998, as previously believed, but 1934, and that six of the 10 hottest years since 1880 antedate 1954. Data from 3,000 scientific robots in the world's oceans show there has been slight cooling in the past five years."

The global warming hoax has never been about the climate. It is about competing economic theories. "Socialism may have failed as an economic theory," wrote Stephens, "but global warming alarmism, with its dire warnings about the consequences of industry and consumerism, is equally a rebuke to capitalism." The United States Senate refused to consider the UN Kyoto Protocol on Climate Change that requires massive reductions in carbon dioxide emissions based solely on the global warming hoax, but other nations did sign on. None have ever met their obligation to limit CO2 emissions, nor need they have bothered.

At the recent G8 conference an international agreement to cut CO2 emissions was given serious consideration despite the fact that the Earth is now a decade into a cooling cycle likely to last several decades or longer. The impact of this proposal on the lives of ordinary citizens will prove needlessly costly. Proposals in some nations for various taxes based on global warming are a form of fraud.

The sensible refusal by leaders in emerging economies such as China and India would make it impossible for any limitations on carbon emissions by Western nations to have any impact, even if such reductions had anything to do with the realities of the Earth's climate. The only thing that can be predicted with certainty is that the Greens will become increasingly unhinged and crazed by the failure of the global warming hoax.
