James Hansen’s latest doomsday paper falls flat on its face, grounds his ‘flying boulders’

James Hansen, formerly head of NASA GISS published a new study Tuesday March 22nd in the journal Atmospheric Chemistry and Physics, claiming global warming, sea level rise, and severe storms, could be (paraphrasing) “worse than we thought”. Just a 2°C rise would see the world suffering through massive sea level rise and super storms that would hurl…

‘Supermandia’ doesn’t seem to like questions about Shukla, #RICO20, and The Climate Science Legal Defense Fund

Long time WUWT readers may remember that a defender of “the cause”, Professor Scott Mandia, donned a Halloween costume and professed his love of defending Michael Mann and others who have had to suffer the terrible, terrible, tragedy of people asking Climategate related questions about validity of science, peer review gatekeeping, and funding. Mike likes the…

Chicken al la still not a king

The royal prince in waiting of Britain labels climate skeptics as “headless chickens”. From The Telegraph: Prince Charles has criticised climate change deniers, describing them as the “headless chicken brigade” during an awards ceremony recognising a leading young green entrepreneur. Charles, who has campaigned for years to reduce global warming, also spoke out against “the…

2013 Was Not A Good Year For Catastrophic Anthropogenic Global Climate Warming Change Disruption Weirding Ocean Acidification Extreme Weather, etc.

Image Credit: European Space Agency – CryoSat By WUWT regular “Just The Facts” For anyone keeping track, 2013 has not been a good year for those who propagate the Catastrophic Anthropogenic Global Warming (CAGW) Narrative, also know by a litany of increasingly nebulous buzzwords including “Climate Change“, “Climate Disruption”“, “Global Weirding”, “Ocean Acidification”, and “Extreme…

Dave’s Top Ten Reasons Why the Oil Industry Doesn’t Spend its Billions on Disproving the Junk Science of AGW

Guest post by David Middleton In my Internet “debates” with warmists, I occasionally encounter challenges like this… We don’t yet not know the real global impact man has on the environment. It may be negligible. What we do know is that if the oil companies with their billions could disprove this manmade warming they could…

A Theory Ready for Extinction

Don’t worry too much over those warmist predictions that millions of species will soon be lost to climate change. Judging by their methods it is the doomsayers who are the real dodos Guest essay by Dr. David Stockwell Will climate change really cause species extinctions? It’s not a simple question to synthesise the connections between…

How a lay climate skeptic’s view can count on global warming

Putting Sir Isaac Newton on the right path Short story by Christopher Bowring When lay global warming skeptics point out to alarmists that the recent seventeen year period of steady global temperatures invalidates their climate models which predicted runaway global warming, there is often a standard response. ‘How can you, global warming (or climate change)…

A call to action – give #ClimateThanks

Another Internet campaign that could go horribly wrong… Tom Nelson advises me that the Yale Project on Climate Change Communications decided to prod readers into giving “Climate Thanks” this Thanksgiving on Twitter. A silly idea for sure, but certainly better than advocating eating “tofurkey” to lessen climate change. I’m sure WUWT readers have lots to…

Gatekeeping at Geophysical Research Letters

Dr. Judith Curry writes: As the IPCC struggles with its inconvenient truth – the pause and the growing discrepancy between models and observations – the obvious question is: why is the IPCC just starting to grapple with this issue now, essentially two minutes before midnite of the release of the AR5? … My blog post…

National Academy of Sciences: climate models still ‘decades away’ from being useful

From the National Academy of Sciences report A National Strategy for Advancing Climate Modeling: Computer models that simulate the climate are an integral part of providing climate information, in particular for future changes in the climate. Overall, climate modeling has made enormous progress in the past several decades, but meeting the information needs of users…

Syun Akasofu’s work provokes journal resignation

Editorial board member pissed off over a paper on “the pause” Story submitted by WUWT reader Duane Oldsen WUWT readers may remember Dr. Syun Akasofu as the source of a graph tracking the Pacific Multidecadal Oscillation with sine wave shifts in global temperature up and down. Dr. Akasofu’s recent submission to the first issue of…

The “Hottest” Temperature Game

Climate Deception: How The “Hottest” Temperature Game Is Played To Offset Prediction Failures Guest essay by Dr. Tim Ball  Global temperature is not doing what the “official” Intergovernmental Panel on Climate Change (IPCC) predicted. Proponents of the claim humans are the cause of warming and the cooperative media react by trying to deflect, divert and…

Current Crop of Computer Models “Close to Useless”

From the Institute for Energy Research: … It is this second class of models, the economic/climate hybrids called Integrated Assessment Models, that Pindyck discusses. Pindyck’s paper is titled, “Climate Change Policy: What Do the Models Tell Us?” Here is his shocking answer, contained in the abstract: 

UAH global temperature, up somewhat

UAH v5.6 Global Temperature Update for June, 2013: +0.30 deg. C by Roy W. Spencer, Ph. D. After 10 days in Michigan’s U.P. for my 40th high school reunion, here’s the belated monthly global temperature update. We added two satellites to the processing, Metop-A starting in 2007 and NOAA-19 starting in 2009.

Call for essays: The 2013 Matt Ridley Prize

The Matt Ridley prize for exposing environmental pseudoscience was inspired by Matt’s discovery that a Ridley family trust was making money from a wind farm company. All too often, hysterical groupthink, based on bad science, creates a climate in which politicians intone ‘something must be done’ and throw millions at pointless schemes. So the Ridley prize is…

An Evidence-Based Approach To Pricing CO2 Emissions

PRESS RELEASE New Paper Proposes Cost-Effective Climate Policy That Gets Around Key Scientific Uncertainties London: A new paper, published today by the Global Warming Policy Foundation, proposes a radical new climate policy approach that offers to be the most cost-effective means of curbing CO2 emissions, while automatically adjusting the stringency of the policy to the…

‘Lewd’ behavior: The pathologising of climate scepticism

ESSAY: The shoddy science of sceptic-bashing LOG12 paper by Lewandowsky attempts to turn rational criticism into a psychological illness. “As the influence of environmental thinking has increased its hold over the political establishment, the failure to win the public support that might create the basis for decisive action to save the planet has also increasingly…

12 Reasons Why The Met Office Is Alarmed

From the GWPF: Met Office To Hold Crisis Summit On Epic Forecast Failures The Met Office’s temperature forecasts issued in 12 out of the last 13 years have been too warm. None of the forecasts issued ended up too cold. That makes the errors systemic and significant. Met Office To Hold Summit On Disappointing (sic)…

An Open Letter To Ed Davey

By Paul Homewood Ed Davey, the UK Secretary of State for Energy, has made a speech attacking the press for reporting the views of climate sceptics, saying “But some sections of the press are giving an uncritical campaigning platform to individuals and lobby groups. This is not the serious science of challenging, checking and probing.…

Australian scientists take 6 degrees of global warming off the table, say it is closer to 2 degrees

From the University of Melbourne Scientists narrow global warming range Australian scientists have narrowed the predicted range of global warming through groundbreaking new research. Scientists from the University of Melbourne and Victoria University have generated what they say are more reliable projections of global warming estimates at 2100. The paper, led by Dr Roger Bodman from Victoria…

Climate models getting worse than we thought

New paper finds climate models are getting worse rather than better Via the Hockey Schtick: A paper published today in Geophysical Research Letters finds that the latest climate models are performing even worse than the earlier generations of climate models in predicting “…both the mean surface air temperature as well as the frequency of extreme…

A case of the vapors – another global cooling mechanism found

From the University of Manchester Organic vapors affect clouds leading to previously unidentified climate cooling University of Manchester scientists, writing in the journal Nature Geoscience, have shown that natural emissions and manmade pollutants can both have an unexpected cooling effect on the world’s climate by making clouds brighter. Clouds are made of water droplets, condensed…

Temperature change in perspective

Guest post by Ed Hoskins The UK Met Office long term Central England Temperature record[1] has kept a continuous and consistent data set since the 1660s. It appears to be reliable and to have maintained its quality. It has not been adjusted as have so many other official temperature records.Although the CET record covers only…

Michael Mann says climate models cannot explain the Medieval Warming Period – I say they can’t even explain the present

Ice core data shows CO2 levels changed less than 10 parts per million from 1600-1800 during the MWP. From the Hockey Schtick:  A new paper from Schurer et al (with Mann as co-author) finds that climate “models cannot explain the warm conditions around 1000 [years before the present, during the Medieval Warming Period] seen in some…
