Global Warming Causes And Effects

Developed countries urged to cut on carbon emission

BEIJING (MindaNews/12 August) – International climate change experts who gathered here last week have called on governments, particularly those of the developed countries, to exert more effort in cutting on carbon emission and create new, green technologies to slowdown the rate of global warming.

The call came as scientists warned that the rapid changes in climatic conditions have made it difficult for species to survive. This is on top of fears that farmlands may no longer be suitable for cultivating crops as a result of global warming.

“The governments aren’t doing very much. In fact the emission [of carbon] is higher now than it has ever been. The rate of [climate] change is faster,” Jeff Price, senior climate change expert of World Wildlife Fund (WWF), said.

“So unless something happens quicker, then you’re easily on the trajectory where looking at the minimum 2°C, which all the governments are saying that’s the maximum we want. But the reality is, they are not doing anything fast enough to stop it because we are on the way to 4°C, where most of the biodiversity can’t adapt,” he added.

Price was referring to the pledges made by countries who participated in the United Nations Copenhagen Accord in 2009 to adopt the 2°C target — a threshold with the equivalent of an atmospheric concentration of 450 parts per million of carbon dioxide equivalent — a safety amount of carbon emission.

“Individual countries are making pledges, but there is no global commitment. And if we are really serious to hold the climate to2°C, it will be a lot less than 450 but we are nowhere near that,” he said.

Yue Ruisheng, deputy department director of China’s Department of International Cooperation of Ministry of Environmental Protection, noted that there is a dire need for governments to fast-track their respective responses to address the serious threats of global warming.

“Government needs to take more action in relation to combat the effects of global warming,” he said, during an international symposium on biodiversity and climate change, which was attended by 120 representatives from different environment organizations and government agencies around the globe.

China and the US, the world’s biggest contributors to carbon emissions, presented their own strategy on the long-term plan to reduce its carbon emission and mechanisms to adapt to the impacts of global warming.

Global Warming | The Year Of The Man Made-Global Warming ...

In 2008, scientists from around the world jump man-made global warming train. This is because the environmental study after study concludes that the behavior of man is not the cause of significant global warming.

In a recently released Geological Society of America abstract, Dr. Don Easter Brook, professor of geology at Western Washington University presented data showing that global warming cycle from 1977 to 1998 is now over and that we have entered into a new global cooling period that should last over the next three decades.

He also suggests that since the IPCC climate models are now so far from what is actually happening that their projections for both this decade and century must be regarded as highly uncertain.

Meanwhile, David Douglass and John Christy, in a paper just accepted for publication and is now available on the Internet, have found that natural changes in global temperature of the water is responsible for an increase in global temperature. Here are their scientific conclusion:

"El Nino and La Nina effects in the tropics have a more significant impact on global temperature anomalies than carbon dioxide, among other things, it was an El Nino event that drove 1998 global temperature maximum."

At NASA, Dr. Roy Spencer, believe cycle accounts for most of last century's warming by carbon dioxide increases by only a modest amount.

His new research, which was submitted to Geophysical Research Letters for publication, show that climate models overestimate the positive feedback from an increase in carbon dioxide, and therefore grossly overstate the projected warming during the next century

In addition, two new studies (article in Science magazine) points to the wind-induced circulation changes in the ocean as the dominant cause of the recent ice losses through the glaciers draining both the Greenland and West Antarctic ice sheets, not 'global warming. '

In June, Dr. David Evans, an architect in Australia's Kyoto compliance, and for years a noted climate change is alarming, the latest man-made global warming doubters. Evans described the four main reasons why 2008 has been years of global warming skeptic and why he recently dropped out of the global warming train.

1.The missing "greenhouse signature", which would be a hot area about 10 km into the atmosphere. It's been sought for years – hundreds of measurements with Radio Sonder (a kind of thermometer weather balloon). It would be the smoking gun. Hundreds of tests have returned the same answer – it's not there. It is statistically impossible that hundreds of tests missed spot. The existing models of the greenhouse effect will not work without this hot zone. 2nd "There is no evidence to support the idea that carbon emissions cause significant global warming," says Evans. "Nothing." There is plenty of evidence that global warming has occurred, and theory suggests that carbon emissions should raise temperatures (though how much is disputed) but there are no observations "which is the evidence that carbon emissions are a major driver of global warming trends. Third Satellites measure the world's temperature shows even that the warming stopped in 2001 and that in the last year the temperature is actually back to 1980 levels. Satellite measurements are the only truly reliable method to capture the data that land-based measurements are vulnerable to abuse by growing cities and "urban heat island effect." 4th "The new ice cores show that over the past six global warm Billings over the past half million years the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon dioxide. Which says something important about which was cause and which was effect.
