First time in 20 years – more daily record lows than daily highs that were either tied or set in 2013

2013 was a cool year in many ways. Most interestingly, the last year this split between highs and lows happened in the USA, in 1993, we had the eruption from Mt. Pinatubo the prior year which ejected so much aerosol into the atmosphere that it blocked sunlight and cooled the planet. Source: http://www.woodfortrees.org/plot/hadcrut4gl/from:1978 This year,…

Claim: November 2013 is the ‘warmest ever’ – but will the real November 2013 temperature please stand up?

Lots of clima-hullaballo this week in the media thanks NOAA and this announcement in NOAA’s “State of the Climate” report seen here: http://www.ncdc.noaa.gov/sotc/global/ They state: The combined average temperature over global land and ocean surfaces for November 2013 was record highest for the 134-year period of record, at 0.78°C (1.40°F) above the 20th century average…

NASA predicts 8 degrees of warming in the US by 2100

For the National Climate Assessment NASA has produced a model-based prediction of eight degrees Fahrenheit for the continental US by 2100 as the most likely scenario Story submitted by Ben Bakker NASA scientists have created a video showing predicted dramatic heating of the continental US between now and the year 2100.  The video and prediction…

Will the real The Death Valley 134F high temperature record please stand up? NWS says one on file at NCDC is a ‘fake’

“…someone made this fake form off the original and even forged Oscar Denton’s name on it.” Readers may recall that last week I noticed differences in the two “official” paper records presented by NOAA/NWS and the National Park Service in their respective web announcements about the 100 year anniversary of the 134°F reading in Greenland…

The Australian Bureau of Meteorology Gets it Wrong

Guest essay by Ed Thurstan Abstract The Australian Bureau of Meteorology (BoM) released a new temperature dataset – the “Australian Climate Observations Reference Network – Surface Air Temperature“ (ACORN-SAT) in early 2012, with data to the end of 2011. It is supposedly a ground-breaking daily homogenised dataset. Ground-breaking it certainly is. The BoM has brought…

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…

Japan’s ‘Cool Hand Luke’ moment for surface temperature

At NASA’s Climate 365, there is an interesting story posted with this statement and a graph: Some say scientists can’t agree on Earth’s temperature changes Each year, four international science institutions compile temperature data from thousands of stations around the world and make independent judgments about whether the year was warmer or cooler than average. “The…

A question for Zeke Hausfather

Zeke is upset that I made this statement in a story at Fox news: Is history malleable? Can temperature data of the past be molded to fit a purpose? It certainly seems to be the case here, where the temperature for July 1936 reported … changes with the moment. In the business and trading world,…

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

NCDC’s new USHCN hockey stick trick

Yesterday, NCDC released Version 2.5 of the USHCN data set. For those who don’t know, this is the U.S. Historical Climatology Network (USHCN) which NCDC considers a “gold standard” for US temperature measurements. Problem is, the reality of the old network is that it is fraught with all sort of inconsistencies throughout its record such…

New national temperature resource almost ready

I had hoped to have this ready in time for heat wave season, as it would have been quite useful in July. Pursuant to my post about July average temperatures being lower with the new Climate Reference Network -vs- the old surface network, let me show you a sneak peak of what will be coming…

NOAA’s ‘Janus moment’ – while claiming ‘The American public can be confident in NOAA’s long-standing surface temperature record’, they fund an experiment to investigate the effects of station siting and heat sinks/sources on temperature data

NOAA’s impersonation of the two faced god Janus just proved my point about station siting issues with their actions that speak louder than words. While there’s all this caterwauling about my PBS News hour interview, and my statements were apparently so threatening that NOAA itself asked PBS to publish a rebuttal in their apologetic story…

PBS backtracks due to viewer pressure

This just appeared on the PBS Blog, apparently the mere presence of my interview was enough to push NOAA into responding. It seems they are in full damage control mode.

July was also the 329th consecutive month of positive upwards adjustment to the U.S. temperature record by NOAA/NCDC

I’ve noticed there’s a lot of frenetic tweeting and re-tweeting of this “sound bite” sized statement from this Climate Central piece by Andrew Freedman. July was the fourth-warmest such month on record globally, and the 329th consecutive month with a global-average surface temperature above the 20th-century average, according to an analysis released Wednesday by the…

NASA’s James Hansen is just wrong: Proof that there is no increased drought in the USA tied to temperature

From the James Hansen is just wrong department comes some inconvenient data, data that Dr. Hansen or anyone in the media could have easily looked up for themselves before writing irresponsible stories like this one: Former Virginia State Climatologist Dr. Pat Michaels, in a guest opinion on WUWT said: Hansen claims that global warming is…

An ‘inconvenient result’ – July 2012 not a record breaker according to data from the new NOAA/NCDC U.S. Climate Reference Network

I decided to do myself something that so far NOAA has refused to do: give a CONUS average temperature for the United States from the new ‘state of the art’ United States Climate Reference Network (USCRN). After spending millions of dollars to put in this new network from 2002 to 2008, they are still giving…

Update on Watts et al. 2012

My sincere thanks to everyone who has provided widespread review of our draft paper. There have been hundreds of suggestions and corrections submitted in comments and in email, and for that I am very grateful.  That sort of input is exactly what we hoped for, and such input can only make the paper better, and…

New paper on the quality of USHCN station siting

Dr. Roger Pielke Sr. draws attention today to a new study that cites Fall et al. 2011 aka the “Surfacestations Paper” that I co-authored, which was a follow up to my original surveys published in Watts 2009. The new paper is: Martinez, C.J., Maleski, J.J., Miller, M.F, 2012: Trends in precipitation and temperature in Florida,…

New paper blames about half of global warming on weather station data homogenization

From the told ya so department, comes this recently presented paper at the European Geosciences Union meeting. Authors Steirou and Koutsoyiannis, after taking homogenization errors into account find global warming over the past century was only about one-half [0.42°C] of that claimed by the IPCC [0.7-0.8°C]. Here’s the part I really like:  of 67% of…

Texas Tall Tales and Global Warming

“…extreme heat events were roughly 20 times more likely in 2008 than in other La Niña years in the 1960s” It is this statement that has made headlines across the country.   Headlines you shouldn’t believe. Guest post submitted by Dr. Cliff Mass University of Washington Last week the national media was full of stories about…

Comparing GHCN V1 and V3

Much Ado About Very Little Guest post by Zeke Hausfather and Steve Mosher E.M. Smith has claimed (see full post here: Summary Report on v1 vs v3 GHCN ) to find numerous differences between GHCN version 1 and version 3, differences that, in his words, constitute “a degree of shift of the input data of…

From a company called Vermont Organics Reclamation, Inc.comes the new “Global Warming Mum” series. Here’s the description: “This series, from breeder Sinclair Adam, Jr, features late bloomers…

Spencer shows compelling evidence of UHI in CRUTem3 data

McKitrick & Michaels Were Right: More Evidence of Spurious Warming in the IPCC Surface Temperature Dataset Guest post by Roy W. Spencer, Ph. D. The supposed gold standard in surface temperature data is that produced by Univ. of East Anglia, the so-called CRUTem3 dataset. There has always been a lingering suspicion among skeptics that some…
