Only 38 Years Until 3C Global Warming?

While we usually think of severe climate change being something that people under age 20 might have to deal with much later in their lives, the findings of a new study suggest that even people now in their 40s or 50s may have to deal with the extreme weather of a world warmed up by 3C. Those planning to retire in the south or southwest perhaps should perhaps reconsider. Maine might be a wiser choice.

The study was the biggest climate computer simulation study ever carried out. It included 10,000 simulations which were run on home computers. The large number of simulations increased the accuracy of the study. The 3C increase is 0.8C higher than the maximum temperature increase of 2.2C by 2050 projected by the Intergovernmental Panel on Climate Change (IPCC). Scientists are extremely concerned about reaching 2C. At the recent Planet Under Pressure conference in London, Will Steffen, executive director of the Australian National University's climate change institute, called for radical action to combat climate change. He said "We can...cap temperature rise at two degrees, or cross the threshold beyond which the system shifts to a much hotter state.” He also noted "Under a worst-case scenario, it's very likely, I think, that the Earth's system will move to a new state of some sort, with a very severe challenge to contemporary civilization…Some people have even talked about a collapse."

All of this seems lost on our politicians representing us in Washington. The gap between science and politics could hardly be any wider. President Obama sounded like he was going to try to close it when he campaigned for office in 2008 but now four years later we are still waiting for him to act on his words.

2008 Ties 2001 for 8th Place on Warmest Year List

Analysis of preliminary global temperature data by the US National Oceanic and Atmospheric Administration (NOAA) found that 2008 was the eighth warmest year since 1880, tying 2001 for the honor. According to NOAA, over the last three decades the global temperature has been increasing by 0.29 degree F (or 0.16 degree C) per decade. Using a different method of analysis but the same data NASA’s Goddard Institute for Space Studies found that 2008 was the ninth warmest year. In any event, the data show that compared to a few decades ago the planet is rapidly heating up and projections are that we “haven’t seen nothin’ yet.” In fact, Purdue University climate scientist Matthew Huber, who applies climate models to past climates says that these models may be underestimating future warming. The NZHerald, a New Zealand website, reports that Huber used one of the same models used by the UN’s Intergovernmental Panel on Climate Change (IPCC) but to make predictions of warming during a warming period 55 million years ago when there was a similar rapid increase of greenhouse gases in the atmosphere and found the temperatures predicted by the model were lower than what actually occurred. The NZHerald site reported that Huber thinks his finding shows that the model is probably predicting temperatures on the low side during the current period of global warming. Yet more evidence that the IPCC has been underestimating the global predicament that we have created.
