Waste heat – a bigger climate effect than once thought
Dr. Roy Spencer recently opined about this issue (which is different from UHI) in: Waste Heat as a Contributor to Observed Warming If we divide that by the surface area of…
Global Temperature Updates – 2012
By Paul Homewood While Obama is imploring us to stop the global warming that is bringing us “the devastating impact of raging fires, and crippling drought, and more powerful storms”,…
The Dr. David Viner moment we've all been waiting for…a new snow record
WUWT readers surely recall this most often quoted prediction about snow. From the Independent’s most cited article: Snowfalls are now just a thing of the past by Charles Onians: However,…
Yet another paper demonstrates warmer temperatures 1000 years ago and even 2000 years ago.
Yesterday I highlighted the paper The extra-tropical Northern Hemisphere temperature in the last two millennia: reconstructions of low-frequency variability, by B Christiansen of the Danish Meteorological Institute and F C…
New paper confirms the climate was warmer 1000 years ago
Mike Mann will have a twitfest on Twitter trying to knock this one down. Data from 91 Northern Hemisphere proxies was used to reconstruct temperature. See reconstruction graph (figure 5)…
New study finds that a Carrington class solar event could cause global cooling of more than 3C
A paper recently published in Atmospheric Chemistry and Physics finds that “a solar proton event, if it took place in the near future with an intensity similar to that ascribed…
Little Ice Age Thermometers- Historic variations in temperatures Part 3 -BEST confirms extended period of warming.
Guest post by Tony Brown This short paper is a preliminary examination of BEST data to 1753, as compared to the Central England Temperature Record (CET) to 1660 (instrumental record)…
NASA's James Hansen's big cherry pick
From NASA: Research Links Extreme Summer Heat Events to Global Warming A new statistical analysis by NASA scientists has found that Earth’s land areas have become much more likely to…
Sea Ice News – Volume 3 Number 8 – meltwater hues, or blues?
WUWT commenter Caleb writes on 2012/07/20 at 7:53 am Check out the “North Pole Camera” on the WUWT “Sea Ice Page.” Both Camera #1 and Camera #2 show lovely summer…
Why the U.S East Coast heatwave was not unusual nor the number of record temperatures unprecedented.
This is a combination of two posts elsewhere that illustrate just how much hype and how little substance the MSM and blogs like Grist, Climate Progress. and Capital Weather Gang…
'We don’t believe the ice cores can be interpreted purely as a signal of temperature'
From the University of Wisconsin: Greenland ice may exaggerate magnitude of 13,000-year-old deep freeze by Chris Barncard Ice samples pulled from nearly a mile below the surface of Greenland glaciers…
Natural Variability in the Widths of the Tropics
Guest Post by Willis Eschenbach In my previous post, “Does This Analysis Make My Tropics Look Big?“I discussed a paper called “Recent Northern Hemisphere tropical expansion primarily driven by black…
The CIA documents the global cooling research of the 1970’s
Despite what NCDC’s Thomas Peterson, Wikiwrangler William Connolley, and John Fleck would like you to believe as a “myth” (The Myth of the 1970s Global Cooling Scientific Consensus), there was…
California Air Resources Board to make webcast on 'black carbon and other “short-lived” greenhouse gases. '
Short notice – this is on NOW. Worth watching, even if only for how they justify saying ‘black carbon and other “short-lived” greenhouse gases.’. I didn’t know black carbon was…
Sea Ice News Volume 3 Number 5 – SEARCH Sea Ice Outlook forecasting contest for 2012
The Arctic sea ice extent forecasting contest is on again. As before I’ll allow readers to submit their best estimates in a poll, and I’ll submit those results as we’ve…
Does This Analysis Make My Tropics Look Big?
Guest Post by Willis Eschenbach There is a new paper in Nature magazine that claims that the tropics are expanding. This would be worrisome because it could push the dry…
Carbon soot may be driving the expansion of the tropics – not CO2
From the University of California – Riverside it seems that black carbon soot is driving tropical expansion. How could this be? I thought CO2 was all powerful, so powerful with…
Shakun The Last, I Hope
Guest Post by Willis Eschenbach In three previous posts here, here, and here, I discussed problems with the paper by Shakun et al., “Global warming preceded by increasing carbon dioxide…
Does CO2 correlate with temperature history? – A look at multiple timescales in the context of the Shakun et al. paper
Guest post by Michael Pacnik Especially in the context of recent discussion of the Shakun et al. paper, a look at other sources for temperature history versus CO2 can be…
