Real Climate

  • Unforced variations: July 2015 - This month’s open thread. How about a focus on cimate science this time? Data visualizations anyone?
  • Heaven belongs to us all – the new papal encyclical - Guest post by Brigitte Knopf With his encyclical “Laudato Si” the Pope has written more than a moral appeal without obligation. He has presented a pioneering political analysis with great explosive power, which will probably determine the public debate on climate change, poverty and inequality for years to come. Thus, the encyclical is also highly […]
  • Debate in the noise - Last week there was an international media debate on climate data which appeared to be rather surreal to me. It was claimed that the global temperature data had so far shown a “hiatus” of global warming from 1998-2012, which was now suddenly gone after a data correction. So what happened? One of the data centers […]
  • NOAA temperature record updates and the ‘hiatus’ - In a new paper in Science Express, describe the impacts of two significant updates to the NOAA NCEI (née NCDC) global temperature series. The two updates are: 1) the adoption of for the ocean temperatures (incorporating a number of corrections for biases for different methods), and 2) the use of the larger International Surface Temperature […]
  • Unforced Variations: June 2015 - This month’s open thread. Some interesting trends in ocean heat content, surface temperatures, multiple oddly reported papers (which are often linked to ambiguous press releases…) etc. But at least we aren’t working in political science…
  • Global warming and unforced variability: Clarifications on recent Duke study - Guest Commentary from Patrick Brown and Wenhong Li, Duke University We recently published a study in Scientific Reports titled . Our study seemed to generated a lot of interest and we have received many inquires regarding its findings. We were pleased with some of coverage of our study (e.g., here) but we were disappointed that […]
  • Unforced Variations: May 2015 - This month’s open thread.
  • How long does it take Antarctica to notice the Northern Hemisphere is warming? - Eric Steig A series of large and abrupt climate changes occurred during the last ice age, most clearly expressed in ice cores from Greenland and other paleoclimate data from the circum-North-Atlantic region. Since the discovery of these events, we’ve been trying to pin down the timing of abrupt climate changes elsewhere on the globe. Were […]
  • Nenana Ice Classic 2015 - Unsurprisingly to anyone looking at the exceptionally warm winter on the West Coast of North America, the Nenana Ice Classic had another near-record early breakup on Friday, netting some lucky winner(s) around $300,000 in prizes. As I’ve discussed previously (last year and an update), the Ice Classic is a lottery that has been run every […]
  • The return of the iris effect? - Guest commentary from Andy Dessler (TAMU) When a new scientific hypothesis is published, two questions always occur to me: Did the authors convincingly show the hypothesis was correct? If not, is the hypothesis actually correct? The answers to these two questions may not be the same. A good example is Wegener’s theory of continental drift […]

Climate Skeptic

  • Matt Ridley: What the Climate Wars Did to Science - I cannot recommend Matt Ridley’s new article strongly enough.  It covers a lot of ground be here are a few highlights. Ridley argues that science generally works (in a manner entirely parallel to how well-functioning commercial markets work) because there are generally incentives to challenge hypotheses.  I would add that if anything, the incentives tend […]
  • Manual Adjustments in the Temperature Record - I have been getting inquiries from folks asking me what I think about stories like this one, where Paul Homewood has been looking at the manual adjustments to raw temperature data and finding that the adjustments actually reverse the trends from cooling to warming.  Here is an example of the comparisons he did: Raw, before […]
  • Mistaking Cyclical Variations for the Trend - I titled my very first climate video “What is Normal,” alluding to the fact that climate doomsayers argue that we have shifted aspects of the climate (temperature, hurricanes, etc.) from “normal” without us even having enough historical perspective to say what “normal” is. A more sophisticated way to restate this same point would be to […]
  • Typhoons and Hurricanes - (Cross-posted from Coyoteblog) The science that CO2 is a greenhouse gas and causes some warming is hard to dispute.  The science that Earth is dominated by net positive feedbacks that increase modest greenhouse gas warming to catastrophic levels is very debatable.  The science that man’s CO2 is already causing an increase in violent and severe […]
  • Those Who Follow Climate Will Definitely Recognize This - This issue will be familiar to anyone who has spent time with temperature graphs.  We can ask ourselves if 1 degree of global warming is a lot, when it is small compared to seasonal variations, or even intra-day variation, you would find in most locations.  That is not a trick question.  It might be important, […]
  • Layman’s Primer on the Climate Skeptic Position - I am a “lukewarmer”, which means a skeptic that agrees that man-made CO2 is incrementally warming the Earth but believes that the amount of that warming is being greatly exaggerated.  In addition, I believe that the science behind evidence of current “climate change” is really poor, with folks in the media using observations of tail-of-the-distribution weather […]
  • When Climate Alarmism Limits Environmental Progress - One of my favorite sayings is that “years from now, environmentalists will look back on the current obsession with global warming and say that it did incredible harm to real environmental progress.”  The reason is that there are many environmental problems worse than the likely impact of man-made global warming that would cost substantially less […]
  • Why We Are Exaggerating “Extreme Weather” - I have written in article at Forbes.com called Summer of the Shark, Global Warming Edition.  It describes why the media, and many average citizens, are exaggerating the degree and effects of extreme weather.  Here is a preview of that article, but I encourage you to read it all In the summer of 2001, a little boy […]
  • HydroInfra: Scam! Investment Honeypot for Climate Alarmists - Cross-posted from Coyoteblog. I got an email today from some random Gmail account asking me to write about HyrdoInfra.  OK.  The email begins: “HydroInfra Technologies (HIT) is a Stockholm based clean tech company that has developed an innovative approach to neutralizing carbon fuel emissions from power plants and other polluting industries that burn fossil fuels.” […]
  • Presentation: The Science of the Skeptic Position - Here is the most recent version of my presentation “Don’t Panic: The Science of the Climate Skeptic Position” I am working to add the narration to it in video form so it is easier to follow. Until I can get that posted, here is my older version of the presentation: Catastrophe Denied: The Science of […]

  • European Renewable Energy performance for 2014 falls far short of claims - Guest essay by Ed Hoskins Summary: By 2014 European Union countries had invested approximately €1 trillion, €1000,000,000,000, in large scale Renewable Energy installations. This has provided a nameplate electrical generating capacity of about 216 Gigawatts, nominally about ~22% of the total European generation needs of about 1000 Gigawatts. The actual measured output by 2014 from data supplied by the…

  • California ‘rain debt’ equal to average full year of precipitation - From NASA/GODDARD SPACE FLIGHT CENTER A new NASA study has concluded California accumulated a debt of about 20 inches of precipitation between 2012 and 2015 — the average amount expected to fall in the state in a single year. The deficit was driven primarily by a lack of air currents moving inland from the Pacific…
