http://www.realclimate.org Climate science commentary by actual climate scientists... Sun, 05 Jul 2009 01:04:49 +0000 http://backend.userland.com/rss092 en Roger Pielke Sr. has raised very strong allegations against RealClimate in a recent blog post. Since they come from a scientific colleague, we consider it worthwhile responding directly. The statement Pielke considers “misinformation” is a single sentence from a recent posting: Some aspects of climate change are progressing faster than was ... http://www.realclimate.org/index.php/archives/2009/07/more-bubkes/ Some parts of the blogosphere, headed up by CEI ("CO2: They call it pollution, we call it life!"), are all a-twitter over an apparently "suppressed" document that supposedly undermines the EPA Endangerment finding about human emissions of carbon dioxide and a basket of other greenhouse gases. Well a draft of ... http://www.realclimate.org/index.php/archives/2009/06/bubkes/ In March the biggest climate conference of the year took place in Copenhagen: 2500 participants from 80 countries, 1400 scientific presentations. Last week, the Synthesis Report of the Copenhagen Congress was handed over to the Danish Prime Minister Rasmussen in Brussels. Denmark will host the decisive round of negotiations on ... http://www.realclimate.org/index.php/archives/2009/06/a-warning-from-copenhagen/ Gavin Schmidt and Michael Mann There was an interesting AP story this week about possible changes in wind speed over the continental US. The study (by Pryor et al (sub.)), put together a lot of observational data, reanalyses (from the weather forecasting models) and regional models, and concluded that there was ... http://www.realclimate.org/index.php/archives/2009/06/winds-of-change/ Alert readers will have noticed the fewer-than-normal postings over the last couple of weeks. This is related mostly to pressures associated with real work (remember that we do have day jobs). In my case, it is because of the preparations for the next IPCC assessment and the need for our ... http://www.realclimate.org/index.php/archives/2009/06/groundhog-day-2/ I don’t tend to read other blogs much, despite contributing to RealClimate. And I'm especially uninterested in spending time reading blogs full of ad hominem attacks. But a handful of colleagues apparently do read this stuff, and have encouraged me to take a look at the latest commentaries ... http://www.realclimate.org/index.php/archives/2009/06/on-overfitting/ Guest commentary by Ron Miller, NASA GISS Several studies have shown that hurricane activity is generally reduced during years when there is a thick aerosol haze over the subtropical Atlantic. The haze is comprised mainly of soil particles, stripped by wind erosion from the barren ground over the Sahara and Sahel. ... http://www.realclimate.org/index.php/archives/2009/05/of-tempests-barren-ground-and-a-thousand-furlongs-of-sea/ Imagine a group of 100 fisherman faced with declining stocks and worried about the sustainability of their resource and their livelihoods. One of them works out that the total sustainable catch is about 20% of what everyone is catching now (with some uncertainty of course) but that if current trends ... http://www.realclimate.org/index.php/archives/2009/05/the-tragedy-of-climate-commons/ Two recent papers (Lockwood & Fröhlich, 2008 - 'LF08'; Scafetta & Willson, 2009 - 'SW09') compare the analysis of total solar irradiance (TSI) and the way the TSI measurements are combined to form a long series consisting of data from several satellite missions. The two papers come to completely opposite ... http://www.realclimate.org/index.php/archives/2009/05/acrim-vs-pmod/ Our favorite contrarian, the potty peer Christopher Monckton has been indulging in a little aristocratic artifice again. Not one to be constrained by mere facts or observable reality, he has launched a sally against Andy Revkin for reporting the shocking news that past industry disinformation campaigns were not sincere explorations ... http://www.realclimate.org/index.php/archives/2009/05/moncktons-deliberate-manipulation/
