Alright, don't hate me for this question:

Why is it that scientists that have credible evidence that shows that global warming isn't man-made treated as Global Warming heretics instead of actually being listened to?

I Found This :

Global cooling in general can refer to a cooling of the Earth. More specifically, it refers to a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis never had significant scientific support, but gained temporary popular attention due to press reports following a better understanding of ice age cycles and a slight downward trend of temperatures from the 1940s to the early 1970s.

Earth as a whole has not been cooling in recent decades, but is in a period of global warming.


Concern peaked in the early 1970s, partly because of the cooling trend then apparent (a cooling period began in 1945, and two decades of a cooling trend suggested a trough had been reached after several decades of warming), and partly because much less was then known about world climate and causes of ice ages. Although there was a cooling trend then, it should be realised that climate scientists were perfectly well aware that predictions based on this trend were not possible - because the trend was poorly studied and not understood (for example see reference[5]). However in the popular press the possibility of cooling was reported generally without the caveats present in the scientific reports.

The term "global cooling" did not become attached to concerns about an impending glacial period until after the term "global warming" was popularized. In the 1970s the compilation of records to produce hemispheric, or global, temperature records had just begun.

A history of the discovery of global warming states that: While neither scientists nor the public could be sure in the 1970s whether the world was warming or cooling, people were increasingly inclined to believe that global climate was on the move, and in no small way.[6]

In 1972 Emiliani warned "Man's activity may either precipitate this new ice age or lead to substantial or even total melting of the ice caps".[7] By 1972 a group of glacial-epoch experts at a conference agreed that "the natural end of our warm epoch is undoubtedly near";[8] but the volume of Quaternary Research reporting on the meeting said that "the basic conclusion to be drawn from the discussions in this section is that the knowledge necessary for understanding the mechanism of climate change is still lamentably inadequate". Unless there were impacts from future human activity, they thought that serious cooling "must be expected within the next few millennia or even centuries"; but many other scientists doubted these conclusions.[9][10]

question: what do you know about the growing ice sheet in greenland?


I Found This :

Researchers have utilised more than a decade's worth of data from radar altimeters on ESA's ERS satellites to produce the most detailed picture yet of thickness changes in the Greenland Ice Sheet.

A Norwegian-led team used the ERS data to measure elevation changes in the Greenland Ice Sheet from 1992 to 2003, finding recent growth in the interior sections estimated at around six centimetres per year during the study period. The research is due to be published by Science Magazine in November, having been published in the online Science Express on 20 October.

ERS radar altimeters work by sending 1800 separate radar pulses down to Earth per second then recording how long their echoes take to bounce back 800 kilometres to the satellite platform. The sensor times its pulses' journey down to under a nanosecond to calculate the distance to the planet below to a maximum accuracy of two centimetres.

ESA has had at least one working radar altimeter in polar orbit since July 1991, when ERS-1 was launched. ESA's first Earth Observation spacecraft was joined by ERS-2 in April 1995, then the ten-instrument Envisat satellite in March 2002.

The result is a scientifically valuable long-term dataset covering Earth's oceans and land as well as ice fields – which can be used to reduce uncertainty about whether land ice sheets are growing or shrinking as concern grows about the effects of global warming.

The ice sheet covering Earth's largest island of Greenland has an area of 1 833 900 square kilometres and an average thickness of 2.3 kilometres. It is the second largest concentration of frozen freshwater on Earth and if it were to melt completely global sea level would increase by up to seven metres.

The influx of freshwater into the North Atlantic from any increase in melting from the Greenland Ice Sheet could also weaken the Gulf Stream, potentially seriously impacting the climate of northern Europe and the wider world.

Efforts to measure changes in the Greenland Ice Sheet using field observations, aircraft and satellites have improved scientific knowledge during the last decade, but there is still no consensus assessment of the ice sheet's overall mass balance. There is however evidence of melting and thinning in the coastal marginal areas in recent years, as well as indications that large Greenland outlet glaciers can surge, possibly in response to climate variations.

Much less known are changes occurring in the vast elevated interior area of the ice sheet. Therefore an international team of scientists - from Norway's Nansen Environmental and Remote Sensing Center (NERSC), Mohn-Sverdrup Center for Global Ocean Studies and Operational Oceanography and the Bjerknes Centre for Climate Research, Russia's Nansen International Environmental and Remote Sensing Center and the United States' Environmental Systems Analysis Research Center – were compelled to derive and analyse the longest continuous dataset of satellite altimeter observations of Greenland Ice Sheet elevations.

By combining tens of millions of data points from ERS-1 and ERS-2, the team determined spatial patterns of surface elevation variations and changes over an 11-year period.

The result is a mixed picture, with a net increase of 6.4 centimetres per year in the interior area above 1500 metres elevation. Below that altitude, the elevation-change rate is minus 2.0 cm per year, broadly matching reported thinning in the ice-sheet margins. The trend below 1500 metres however does not include the steeply-sloping marginal areas where current altimeter data are unusable.

The spatially averaged increase is 5.4 cm per year over the study area, when corrected for post-Ice Age uplift of the bedrock beneath the ice sheet. These results are remarkable because they are in contrast to previous scientific findings of balance in Greenland's high-elevation ice.

The team, led by Professor Ola M. Johannessen of NERSC, ascribe this interior growth of the Greenland Ice Sheet to increased snowfall linked to variability in regional atmospheric circulation known as the North Atlantic Oscillation (NAO). First discovered in the 1920s, the NAO acts in a similar way to the El Niño phenomenon in the Pacific, contributing to climate fluctuations across the North Atlantic and Europe.

Comparing their data to an index of the NAO, the researchers established a direct relationship between Greenland Ice Sheet elevation change and strong positive and negative phases of the NAO during winter, which largely control temperature and precipitation patterns over Greenland.

Professor Johannessen commented: "This strong negative correlation between winter elevation changes and the NAO index, suggests an underappreciated role of the winter season and the NAO for elevation changes – a wildcard in Greenland Ice Sheet mass balance scenarios under global warming."

He cautioned that the recent growth found by the radar altimetry survey does not necessarily reflect a long-term or future trend. With natural variability in the high-latitude climate cycle that includes the NAO being very large, even an 11-year long dataset remains short.

"There is clearly a need for continued monitoring using new satellite altimeters and other observations, together with numerical models to calculate the Greenland Ice Sheet mass budget," Johannessen added.

Modelling studies of the Greenland Ice Sheet mass balance under greenhouse global warming have shown that temperature increases up to about 3ºC lead to positive mass balance changes at high elevations – due to snow accumulation – and negative at low elevations – due to snow melt exceeding accumulation.

Such models agree with the new observational results. However after that threshold is reached, potentially within the next hundred years, losses from melting would exceed accumulation from increases in snowfall – then the meltdown of the Greenland Ice Sheet would be on.

A paper published in Science in June this year detailed the results of a similar analysis of the Antarctic Ice Sheet based on ERS radar altimeter data, carried out by a team led by Professor Curt Davis of the University of Missouri-Columbia.

The results showed thickening in East Antarctica on the order of 1.8 cm per year, but thinning across a substantial part of West Antarctica. Data were unavailable for much of the Antarctic Peninsula, subject to recent ice sheet thinning due to regional climate warming, again because of limitations in current radar altimeter performance.

ESA's CryoSat mission, lost during launch on 8 October, carried the world's first radar altimeter purpose-built for use over both land and sea ice. In the context of land ice sheets, CryoSat would have been capable of acquiring data over steeply-sloping ice margins which remain invisible to current radar altimeters - these being the very regions where the greatest loss is taking place.

Efforts are currently underway to investigate the possibility of building and flying a CryoSat-2, with a decision to be taken by the end of the year. In the meantime, the valuable climatological record of ice sheet change established by ERS and Envisat will continue to be extended.

Alright, here is a question for you
When we gonna die (or kill ourselves)?
PostPosted: Sat Aug 25, 2007 7:14 am


If in the sense of Global Warming, it is estimated that over the next 1 century, temperature with rise beyond expectations. It is also estimated that Global Warming might kill humanity in about 2 centuries. If Global warming doesn't kills us, it also predicted that the Sun will die about 4 billion years later.

Flash! Global Warming May Bring Ice Age By The Next Election
By Paul F. Stifflemire, Jr.
CNSNews.com Commentary
February 10, 2004

Well, perhaps not that soon; but readers of Fortune magazine, normally a reserved, fairly objective periodical concerned with business and economic stories may be forgiven for a little worry if not complete confusion.

In the February edition is an exciting piece entitled "CLIMATE COLLAPSE The Pentagon's Weather Nightmare," by David Stipp. He essentially tells readers that the prospect of global warming pushing the world climate to a "tipping point" has "become so real that the Pentagon's strategic planners are grappling with it."

Stipp states that "growing evidence suggests the ocean-atmosphere system that controls the world's climate can lurch from one state to another in less than a decade...." This "evidence," he says, suggests the possibility of a cacophony of climate disasters--longer, harsher winters in the US and Europe; massive droughts "turning farmland to dust bowls and forests to ashes"--that could upset the geopolitical mix and "destabilize nuclear powers such as Pakistan and Russia."

Wow. All that drama based on, well, not much, actually. "...Data show that a number of dramatic shifts in average temperature took place in the past with shocking speed--in some cases, just a few years," Stipp reports without citing the specific evidence or, for that matter, any scientists engaged in anything more definite than conjecture.

What is so amusing about this particular journalistic work is the attempt to lend credibility to junk science by fastening it to the Pentagon. The media were quick to attack the idea of the Pentagon spending money to study the possibility that markets could predict terrorist attacks. But Stipp and Fortune appear to be suggesting that Pentagon gaming and "what if" analysis of possible consequences stemming from abrupt climate change is sufficient evidence global warming constitutes an imminent threat, so to speak, and warrants preemptive action.

Reading through the article, claimed to be based on an "unclassified report completed late last year that the Pentagon has agreed to share with Fortune" causes one to laugh out loud. It is especially noteworthy that among the credentials cited for one of the report's authors is his work on the Steven Spielberg film "Minority Report." The result is, indeed, science fiction at its best.

The theory, in a nutshell, is this: the globe's climate is totally dependent upon a "huge Atlantic Ocean current" the alarmists liken to a "conveyor" that brings warm, temperate climates and moisture from the tropics to the eastern U.S. and northern Europe. Global warming will deposit more fresh water into the North Atlantic, turn off the conveyor, and plunge the northern hemisphere into an ice age. In less than ten years temperatures fall dramatically in North America, Asia and Europe, the average annual rainfall decreases 30% and massive droughts begin. Simultaneously, violent storms increase, making coastlines from the Netherlands to Bangladesh unlivable. Though the U.S. is able to cope with "megadroughts," the have-nots in the rest of the world turn against us. We survive (in part by coming to our senses and building new nuclear energy facilities) after a struggle. But those less fortunate around the globe revert to their pre-industrial, pre green revolution ways, and "desperate, all-out wars over food, water and energy supplies" commence in earnest.

What to do? Stipp, speaking on behalf of the science fiction writers provides a handy, if predictable answer: "...given its dire consequences [environmental Armageddon] should be elevated beyond a scientific debate....some federal thought leaders may be starting to perceive climate change less as a political annoyance and more as an issue demanding action. If so, the case for acting now to address climate change, long a hard sell in Washington, may be gaining influential support, if only behind the scenes. Policymakers may even be emboldened to take steps such as tightening fuel-economy standards for new passenger vehicles...." Hopefully, that is science fiction as well.

What is so astounding about this "journalism" is its lack of embarrassment and the fact that Fortune's editors saw fit to allow it to escape the waste basket. This story has been wending its way around the Internet for some time; we suppose it was only a matter of more time until it showed up in one or another respected "mainstream" publication.

In a companion piece, Stipp makes the fabulous assertion that "Scientists used to think that major climate changes, like the onset of an ice age, took thousands of years to unfold. Now they know such dramatic transitions can occur in less than a decade." They do?

Frankly, David Stipp, who has been writing on science for the Wall Street Journal and then Fortune since the 1980s, ought to be possessed of a bit more savvy than is displayed in this effort.

The "evidence" for abrupt climate change having occurred is based on examination of data pointing to what some, not a majority of scientists consider the most recent past occurrence. That was at least 11,500 years ago, well before man started tinkering with greenhouse gases and under global climate conditions vastly different from today. But having failed to stampede US politicians into draconian, economy-busting restrictions on carbon gas based on threats of heat-induced catastrophe over two hundred years or so, the people behind this ice folly are trying a new tack: Unless we immediately reverse the headlong rush of industry-precipitated global warming, we could be in an Ice Age before the 2008 election.

Sensible journalists, with the slightest bit of skepticism in their make up, might detect just a bit of desperation in this fable. Or, perhaps the following might have tripped the smell-o-meter: "... [This] summer 20th Century Fox is expected to release 'The Day After Tomorrow,' a big-budget disaster movie starring Dennis Quaid as a scientist trying to save the world from an ice age precipitated by (wait for it) global warming." That bit of telling "news" was slipped by Stipp into his Fortune article, indicating, hopefully, that his tongue was planted firmly in cheek while he wrote it.

No more questions at the moment for me but I do believe that global warming is pushing us too that rather 'icy' tipping point for example:

-NYC record snowfall-2006

-VA record snowfall, visible from space-2004

-Of course the 1999 ice storm of the east coast that left millions without power.

-Alaskan, Canadian, Norwegian, Antarctic, and Siberian Glaciers Advancing!

-Greenland's vast interior growing

-Antarctica Growing fast!

-2006-2007 winter so cold that quite a few people in the midwest and east died from the extreme arctic temps.

-Also people seem to forget this but in VA 2005 and 2006 summer had over 20 days were the heat index was 120 degrees, this summer-2007 there have not been any days that registered 120 and where I live in Southampton County that hottest its felt is 100-105, thats a drastic cool down!
