Climate models are made out of all of these cells. The are typically about 10 km on edge (62 miles). Temperature analysis is done on a gridded basis. The scientists do not use the obviously heat modified temperatures of urban weather stations unadjusted. That would be unintelligent. The weather stations in each grid are all…
It never ceases to amaze me – the tenacity of the dedicated climate skeptics. Now they are leading a race to see how many people they can convince that climate change is not real because they say we are not setting a global temperature records every single year. They do not understand that the chaos…
This is about complex atmospheric chemistry. Our previously simple understanding of the concentration of greenhouse gases in our atmosphere does not do justice to the complex atmospheric chemistry that goes on 24/7. The explanation is not so complex though. Methane reacts differently with different things in the atmosphere at different times. These different reactions tell…
Well, they told us this would happen. Since the early 1980s. scientists have been saying that the weather would get more variable, that storms would get worse in a warmer planet. A new report by the National Wildlife Federation reports that this is just what is happening. The last couple of winters have been peculiarly…
From the Seattle Times, Jan 20, 2010: "If you see these changes across an entire ocean basin, you can be assured it’s happening on a global scale in other ocean basins around the world," said Robert Byrne, a marine chemist at the University of South Florida and lead author of an upcoming paper in Geophysical…
In the U.S., 2009 was 0.3 degrees F above the 20th century average. The solar minimum continues. The two year lag from the Pacific Decadal Oscillation continues. This is why it is not 1.3 degrees above normal or more. I have attached a view of Arctic sea ice extents from the National Snow and ice…
Yes there was a mistake in the 2007 IPCC report, I am sure there were more than one. The biggest mistake is that the report does not go far enough in projecting future climate change. Virtually everything that the report has projected has been proven to be conservative. There are even a number of things…
This study from Yale, the University of Hong Kong and U of C Santa Cruz looked at climate between 3 and 5 million years ago, the point in the past when temperatures were as close to today as they have been since. Their goal was to find a stable warm climate state and evaluate the…
It’s the Laptev Sea again. This is the part of the Arctic Ocean that is just north of Siberia (see here). The springtime air temperature across the region in the period 2000-2007 was an average of 4C higher than during 1970-1999, likely the highest temperature rise on the planet. The estimate of carbon locked up…
Arctic sea ice may disappear by 2013: Arctic sea ice is in trouble and the implications of the global feedback caused by the lack of sea ice are extreme. Open water absorbs eight times more heat than does ice. Ice reflects the heat harmlessly back to space. Water keeps the heat to melt more ice…
