AGW Proponents Fight Rearguard Action As Political Climate Science Fails
Guest post by Dr. Tim Ball Proponents of the anthropogenic global warming (AGW) hypothesis are cornered. They made a political choice to prove rather than disprove the hypothesis, as the…
Global warming – more complex than we thought
From the University of Hawaii ‑ SOEST, more modeling mania for the future. New research shows complexity of global warming Greenhouse gases versus solar heating Global warming from greenhouse gases…
The age old battle of the thermostat – the 'Goredian' Knot of global temperature
People send me stuff. Reader Kurt writes: I just found your excellent website and have book marked it and will visit it often for updates. One simple question the global…
More on Mark Hertsgaard's ridiculous claims – The Goldilocks Crop and the Impending Extinction of Pasta
Guest Post by David Middleton Yesterday, WUWT covered the issue from one angle, and blew Hertsgaard’s riduculous claims out of the water. Today, here’s another independently arrived at conclusion that…

Speak loudly and carry a busted hockey stick
by Walter Starck (in Quadrant Online) The average temperature for the Earth, or any region or even any specific place is very difficult to determine with any accuracy. At any…
Mann's hockey stick disappears – and CRU's Briffa helps make the MWP live again by pointing out bias in the data
Shock, awe. Untruncated and unspliced data used in a new paper from Briffa and Melvin at UEA restores the Medieval Warm Period while at the same time disappears Mann’s hockey…
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)…
Want to make a paper more alarming and appealing to coverage? Blame the Romans for climate change
By comparing today’s Nature paper to earlier versions I found just a few months old, it looks like some blame revisionism occurred after early discussions of this paper at NOAA…
Make your own Michael Mann hockey stick at home
Following yesterday’s first look at emails from the 2 year effort to get NOAA to release emails from FOIA requests, where we learn that some scientists felt ‘Hit on the…
Another paper refutes the Mann made hockey stick – MWP was ≈1°C warmer than current temperatures
This new paper uses a rather unique proxy; high-resolution samples micromilled from archaeological shells of the European limpet, Patella vulgata. Mr. Limpet would be proud. A paper published this week…
Linking the ENSO and PDO induced rainfall of the Pacific Northwest to proxy data in tree rings and lake sediments
From Penn State , another Mann paper with proxy sets, and a divergence problem. At least they are talking about the MWP, or as they call it, the Medieval Climate…

Megafire study suggests today’s megafires, at least in the southwestern U.S., are atypical
From SMU (Southern Methodist University) comes this press release which really isn’t surprising. North America didn’t have a forest fire suppression program for the last 1400 years, so there wasn’t…
More solar linkages to climate variations
From Pierre Gosselin’s No Tricks Zone: Oases of the Chinese Taklamakan Desert Greened Up In Sync With Solar Millenial Cycles by Sebastian Lüning and Fritz Vahrenholt The Taklamakan Desert is…
Pat Michaels – on the death of credibility in the journal Nature
Atmospheric Aerosols and the Death of Nature Guest post by Dr. Patrick Michaels Big news last week was that new findings published in Nature magazine showed that human emissions of…
Proof that "climate disruption" is found all the way back to pre-industrial times
A new paper in Quaternary Science Reviews titled: Combined dendro-documentary evidence of Central European hydroclimatic springtime extremes over the last millennium …demonstrates that there is evidence for extreme weather during…
Yes, I know, I covered it first: The Medieval Warm Period was Global
I must have had 20 tips and notes/contacts over the past 24 hours like this one: New temperature proxy discovered An article (http://www.dailymail.co.uk/sciencetech/article-2120512/Global-warming-Earth-heated-medieval-times-human-CO2-emissions.html) in the Mail Online describes a paper…
