Global Warming Caused Vikings to Become Terrorists

David Middleton From the Climate Change Causes Everything Files: SCIENCE — We know Vikings as infamous raiders—was that merely a response to climate change? Changing temps may have impacted the ability to farm, leading to new economic strategies. K.N. SMITH – 8/6/2017 Beneath their still surfaces, the lakes of some Arctic islands may hide the…

Claim: Solar activity not a key cause of climate change, study shows

From the University of Edinburgh , another one-paper syndrome in the making funded by an NGO research council with a political mission to grab a headline. And, another poorly written press release where they don’t even cite the name of paper. Sigh. ============================================================ Climate change has not been strongly influenced by variations in heat from…

Intelligence and the hockey stick

Guest essay by Christopher Monckton of Brenchley In 1990, the IPCC’s First Assessment Report showed a schematic demonstrating the then understanding that the medieval warm period had been appreciably warmer than the present and that the Little Ice Age had been colder. However, in 1995 Dr. Jonathan Overpeck, an IPCC scientist, wrote an email to…

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…

The Medieval Warm Period in the Arctic

Since the IPCC AR5 is again making news in talking about the Medieval Warm Period, this review from Craig Idso at CO2Science.org seems appropriate. -Anthony Medieval Warm Period (Arctic) — Summary This review begins with the study of Dahl-Jensen et al. (1998), who used temperature measurements from two Greenland Ice Sheet boreholes to reconstruct the…

Remarkable correlation of Arctic sea ice to solar cycle length

This is interesting, especially since Solar Cycle 23 was quite long. The Hockey Schtick writes: A paper published by the Danish Meteorological Institute finds a remarkable correlation of Arctic sea ice observations over the past 500 years to “the solar cycle length, which is a measure of solar activity. A close correlation (R=0.67) of high significance (0.5…

Hot weather and climate change – a mountain from a molehill?

Guest essay by Steve Goreham Originally published in The Washington Times On Sunday, Death Valley temperatures reached 129oF, a new June record high for the United States, according to the National Weather Service. Temperatures at McCarran International Airport in Las Vegas reached 117oF, tying the previous record set in 1942 and 2005. National Geographic, NBC…

Global Warming theory has failed all tests, so alarmists return to the ‘97% consensus’ hoax

 Guest essay by Joseph D’Aleo, CCM, Weatherbell Analytics National Academies of Science defines a scientific theory as “a well-substantiated explanation of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.” Dr Richard Feynman, Cornell Physicist in a lecture explained how theorys that failed the test of data or experiment are falsified (“wrong”)…

Briffa, Yamal, reputational damage, and all that

Keith Briffa has just published a new paper using the Yamal-Urals regional chronology data, something long sought after via FOIA requests. That data was withheld, citing it wasn’t cooked done with yet, and that releasing it would damage the reputation of CRU scientists. After Climategate in 2009, I’m not sure how CRU’s reputation could be…

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…

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 scientific method requires. It failed, as IPCC projections (range of predictions?) indicate, but instead of abandoning or modifying the hypothesis, as normal science requires, they’ve…

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 suggests Hertsgaard’s claims are pure fantasy. It is apparently becoming too warm to grow wheat… Bakken Oil Boom and Climate Change Threaten the Future of…

The Atlantic Magazine’s ‘5 Charts About Climate Change That Should Have You Very, Very Worried’… Worried about scientific illiteracy.

Guest post by David Middleton I ran into this gem on Real Clear Energy this morning… The article cites terrifying new reports commissioned by the World Bank and the CIA and then launches into a graphical cornucopia of nonsense. The Five Charts of Doom

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 given time surface air temperatures around the world range over about 100°C. Even in the same place they can vary by nearly that much seasonally…

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 stick. Here’s figure 5 that tells the story: Look at graph 5c, and you’ll see 20th century warmth matches peaks either side of the year…

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 Ljungqvist of Stockholm University which showed that using a multitude of proxy samples in the norther hemisphere, that: “The level of warmth during the peak…

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 in May 2012. Over at Australian Climate Madness, Simon points out the coverage of the ABC for this new paper in Nature. He writes: ==========================================================…

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 in the journal Palaeogeography, Palaeoclimatology, Palaeoecology finds that the Medieval Warming Period “was warmer than the late 20th century by ~1°C.” The paper adds to…

Mann’s ‘hockey stick’ claims of the MWP and LIA being local were refuted years before it was published

Pierre Gosselin at NoTricksZone reports: Geologist Dr. Sebastian Lüning and Prof. Fritz Vahrenholt found a Japanese tree-ring temperature reconstruction from 1995, one that should have been heeded by the IPCC and Michael Mann before they took the world on a 10-year joyride in the stolen car of “climate science”. Here’s the Google translation of their article, with…

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 a fuel buildup issue like we have today, forest floors were cleansed naturally by non-catastrophic fires. Ancient tree-ring records from southwest U.S. suggest today’s megafires…

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 the 2nd world’s largest sand desert after the Rub el-Khali Desert in Saudi Arabia. A Chinese-Australian team of scientists lead by Keliang Zhao of the…

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 (http://www.sciencedirect.com/science/article/pii/S0012821X12000659) detailing a new temperature proxy that indicates that the Medieval Warm Period was global, not merely regional. WUWT had the story first, 5 days…

Weekly Climate and Energy News Roundup

Quote of the Week: “I am always happy to be in the minority.  Concerning the climate models, I know enough of the details to be sure that they are unreliable. They are full of fudge factors that are fitted to the existing climate, so the models more or less agree with the observed data. But…

More evidence the Medieval Warm Period was global

UPDATE: 3/30/12 Since a number of commenters that are getting bent out of shape over the issue can’t apparently be bothered to read the paper, and since the authors at Syracuse themselves are under pressure because the alarmosphere has gone ballistic over the possibility that Mike Mann’s “there is no MWP much less global” gospel…

Ancient Iraqi meteorologists speak to the present on climate

From Wiley-Blackwell via Eurekalert Ancient Arabic writings help scientists piece together past climate Iraqi sources from 9th and 10th centuries give new meteorological insights – The team believes the sources show Iraq to have experienced a greater frequency of significant climate events and severe cold weather than today. Ancient manuscripts written by Arabic scholars can…

Monckton responds to Skeptical Science

Cooking the books By Christopher Monckton of Brenchley Mr. John Cook, who runs a website puzzlingly entitled Skeptical Science” (for he is not in the least sceptical of the “official” position) seems annoyed that I won the 2011 televised debate with Dr. Denniss of the Australia Institute, and has published a commentary on what I…

The Message in the Dye 3 Data

Guest post by David Archibald The story so far: in this recent post – Ap Index Neutrons and Climate, we had looked at the Dye 3 oxygen isotope-derived temperature record to see how big climate swings have been over the last few thousand years.
