When it comes to climate, the early Paleogene period (~65-34 mya), at the start of the Cenozoic Era, had one of the most Eden like climates of the Phanerozoic Eon. As the Cenozoic progressed a cooling trend set in leading up to the formation of permanent ice caps and the Pleistocene Ice Age we are still experiencing. But before the world started to ice up our planet underwent one of the most dramatic bouts of global warming known to science—the Paleocene Eocene Thermal Maximum or PETM. Recently, global warming activists have tried to liken human CO2 emissions to the cause of the PETM, 55 million years ago. Is it true, that our actions may trigger a sudden sharp rise in global temperature?
Many news outlets are reporting that the Environmental Protection Agency may have suppressed an internal report that was skeptical of claims about global warming. While this has conspiracy theorists all a twitter, the truly shocking thing is the content of that report. The executive summary contains a list of items contradicting claim after claim put forth by the IPCC and global warming alarmists. The contents are nothing short of incendiary.
The current hot phrase bandied about by talking heads and parotted by news pundits is “tipping point.” We are told that the climate may be near a tipping point, if it has not crossed one already, and that can't be good. But what is a tipping point, where do they come from and how can we identify one when we see it?
“The worst-case IPCC projections, or even worse, are being realized,” said Katherine Richardson, co-chair of the Copenhagen Climate Congress. Emissions are soaring, projections of sea level rise are higher than expected, and climate impacts around the world are appearing with increasing frequency, the University of Copenhagen biological oceanographer told delegates in the opening session of the 3-day meeting. Why are the doomsayers suddenly all over the news media? Because of the changing climate—the political climate that is.
Most everyone has heard the recent announcement that Global Warming has been put on hold for 20 to 30 years. Earth's variable climate continues to make fools of climate scientists, obstinately refusing to follow the IPCC's climate change script. Why? Because the climate change doomsayers put their faith in computer models, not in hard science.
In May, 2008, the National Snow and Ice Data Center (NSIDC) predicted that the North Pole could be ice free during last years melt season. The disappearing northern sea ice has been pointed to by global warming alarmists as visible proof that the Earth was doing a melt down. Today, however, the NSIDC announced that they have been the victims of “sensor drift” that caused them to underestimate the Arctic ice extent by as much as 500,000 square kilometers. It turns out that the demise of the arctic ice was greatly exaggerated.
One of the catastrophic results of global warming always cited by climate change alarmists is the melting of the ice sheets covering Greenland. Some even speculated that global warming had pushed Greenland past a “tipping point” into a scary new regime of wildly heightened ice loss and rapidly rising in sea levels. Now, from the fall meeting of the American Geophysical Union, comes word that Greenland's Ice Armageddon has been called off.
There have been a number of near hysterical reports that the Greenland and Antarctic ice sheets are melting much faster than anticipated. This has been trumpeted as prima facia evidence that Global Warming is accelerating and we will soon see marked increases in sea levels world wide. The surging glaciers from both the Greenland and West Antarctic ice sheets have alarmed scientists, eco-advocates and the news media alike. However, two new studies point to random, wind-induced circulation changes in the ocean—not global warming—as the primary cause of the recent glacial ice losses.
With the US storm tossed in the midst of the 2008 Hurricane season the predictable has happened: the United Nations Environment Program (UNEP) has released another report claiming that global warming is boosting the strength and number of storms around the world and in the Atlantic. In a press release dated September 4, UNEP blames climate change for the rising cost of natural disasters around the world.
