The National Snow and Ice Data Center (NSIDC) report on March 19, 2015 shows Arctic sea ice has reached its lowest winter minimum on record. The record only goes back to 1979, but conclusions can be drawn from the record and global temperature that show global warming at work. This interactive chart is the NSIDC…
The most recent discoveries in climate science bear little resemblance to what we hear in the media. Greenland’s melt in 2012 for example has been widely advertised in the media as just another weather event, similar to many in the past. The adage that we cannot tell for sure if any single weather event was…
It appears that we have truly crossed a threshold. Since 2005, every year Arctic sea ice extents have been below every other year in the record back to 1979. Of course, we can’t tell with absolute statistical certainty. But we have been warned for decades that this would happen. This year’s melt record exceed the…
Abrupt climate change has arrived. They told us this would happen twenty years ago if we did not reduce emissions. We did not and it has. The U.S. Global Change Research Program (USGCRP), a Ronald Reagan Presidential Initiative formerly called the U.S. Climate Change Science Program, tells us an important truth in the climate change…
Arctic sea ice has smashed its last smashed record by a margin nearly as great as the previous smashing. The minimum Arctic sea ice record set in 2007 was widely believed to be a freak, caused by freak weather conditions. It shattered the previous record by 22 percent. This year’s record shattered the 2007 record…
If sea level rises just three feet, 1.5 million housing units will be flooded and 3.7 million people displaced. Pick an amount of sea level increase, any old amount will do. The minimum is the IPCC estimate of about 15 inches (a half meter). This of course does not include any increase in discharge from…
