Needless to say Dr Ole Humlum’s survey is unlikely to be popular in climate alarm circles.

London, 22 March: A report on the State of the Climate in 2016 which is based exclusively on observations rather than climate models is published today by the Global Warming Policy Foundation (GWPF). 

Compiled by Dr Ole Humlum, Professor of Physical Geography at the University Centre in Svalbard (Norway), the new climate survey is in sharp contrast to the habitual alarmism of other reports that are mainly based on computer modelling and climate predictions.

Among the key findings of the survey are:

Had enough of climate propaganda?


Last week EPA Administrator Scott Pruitt stated that: “I think that measuring with precision human activity on the climate is something very challenging to do, and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.”

I can only applaud Pruitt’s thoughtful comments, writes Alan Carlin.

But in fact there is not just uncertainty as Pruitt said, but actual evidence that there are no significant effects of rising human-caused emissions or atmospheric CO2 levels on global temperatures.

US Environmental Protection Agency (EPA) chief Scott Pruitt


BBC News all but bursts a blood vessel over the EPA head’s opinion that the climate science ‘debate’ is not settled. Their reaction is to trot out some standard warmist platitudes, which surprises nobody.

US Environmental Protection Agency (EPA) chief Scott Pruitt has said he “would not agree” carbon dioxide is a primary contributor to global warming.

He told CNBC that measuring human impact on the climate was “very challenging” and there was “tremendous disagreement” about the issue.

Mr Pruitt instead insisted that officials needed “to continue the debate” on the issue. His remarks contradict his own agency’s findings on greenhouse gas emissions.

Can the tropics ever get too hot for life on Earth, or not? That’s the question posed by this research. As the report notes: ‘these theories are controversial’.

New research findings show that as the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn’t survive, reports Phys.org.

Longstanding theories dating to the 1980s suggest that as the rest of the earth warms, the tropical temperatures would be strictly limited, or regulated by an internal ‘thermostat.’

These theories are controversial, but the debate is of great importance because the tropics and subtropics comprise half of the earth’s surface area, greater than half of the earth’s biodiversity, as well as over half the earth’s human population.

But new geological and climate-based research indicates the tropics may have reached a temperature 56 million years ago that was, indeed, too hot for living organisms to survive in parts of the tropics.

They admit the hiatus, or pause, is still a puzzle: ‘processes remain unclear’. What is clear is that the observed temperature trend in the study period is unlike the carbon dioxide trend.

The increasing rate of the global mean surface temperature was reduced from 1998 to 2013, known as the global warming hiatus, or pause.

Researchers have devoted much effort to the understanding of the cause, reports Phys.org. The proposed mechanisms include the internal variability of the coupled ocean-atmosphere system, ocean heat uptake and redistribution, and many others.

However, scientists also want to understand the atmospheric footprint of the recent warming hiatus as the dynamical and physical processes remain unclear.

Some of the blazes were accidental, and as people travel more the areas at risk are increasing.

A new study blames people for triggering five out of every six wildfires in the United States and tripling the length of the wildfire season, reports the Daily Mail Online.

Even as climate change worsens the nation’s fire season – making it longer and easier to burn more acres – researchers say human activities play an even bigger role.

Scientists looking at fire data from 1992 to 2012 found that 84 percent of all U.S. wildfires were started by people, either by accident or on purpose.

The arguments stirred up by the NOAA’s ‘pausegate’ whistleblower rumble on. A UK Met Office expert asserted ‘the slowdown hasn’t gone away’. This one could run and run.

David Rose’s splendid and significant article in last week’s Mail on Sunday certainly caused a stir. The initial reaction, mostly distractions, have been easily dealt with by David Rose in this week’s installment.

One of the points raised concerned a paper submitted to the Journal of Climate by Huang et al. It is about the new ERSSTv5 sea surface temperature dataset.

It is an interesting paper that claims that ERSSTv5 shows a lower rate of warming than the previous ERSSTv4 which was used by the now famous Karl et al paper in 2015 which claimed that — contrary to the IPCC — there had been no slowdown in the rate of temperature increase in the past 15 years or so – the so-called Pause.

One persistent activist said the paper was stolen and it was unethical to comment on it. In reality the preprint was obtained from a public webpage, anyone could have downloaded it. It has been in circulation for weeks.

One letter changes in the new US climate policy: ‘defund’ replaces ‘defend’. Interesting times ahead.
H/T GWPF

US president Donald Trump will honour his campaign pledge to pull the US out of the Paris climate agreement and defund UN climate programmes, a former adviser to the new administration has said.

Myron Ebell served as head of the Environmental Protection Agency’s (EPA) transition team from early September until 19 January, when he helped to draft an advisory action plan on how to implement Trump’s campaign promises.

At a press briefing held by the Global Warming Policy Foundation (GWPF) and the Foreign Press Association (FPA) in London today, Ebell declined to divulge any details of the EPA document on the grounds that it is confidential.

But Ebell, a well-known climate change sceptic and head of the Competitive Enterprise Institute’s (CEI) energy and environment centre, outlined Trump’s “very clear” promises on energy and the environment that he is convinced the new president will honour.

Alan Carlin argues that the stability of the Earth’s climate within its two fundamental modes, glacial and interglacial, is underestimated or ignored by climate modellers in their desire to talk up supposed human-caused factors.

The UN IPCC reports on climate are truly unusual scientifically.

Without any serious discussion or even an attempt to point out their unusual nature, they try to convince readers that the basic nature of Earth’s climate has been radically changed after millions of years, all because one very minor constituent of the atmosphere has been increasing, as it usually does during interglacial periods in response to higher temperatures.

During this long period the basic nature of Earth’s climate can be characterized as bistability. In other words, Earth has had dual climate equilibria. One occurs during ice ages and the other during interglacial periods. Both are very stable except that Earth flips from the ice age equilibrium to the interglacial roughly every 100,000 years and flips back again after another 10,000 to 12,000 years.

History suggests that we may be close to the next flip into an ice age, the colder of the two bistability climates. This has enormous implications for humans and all life on Earh. But the upper “limit” on interglacial temperatures does not appear to have been breached in all that time.

Quote: The earth has been in an interglacial period known as the Holocene for more than 11,000 years. It was conventional wisdom that the typical interglacial period lasts about 12,000 years, but this has been called into question recently. – Wikipedia

Climate alarmists are primarily concerned that man’s activities will result in Catastrophic Anthropogenic Global Warming (CAGW). They appear to have missed the big picture.

Global atmospheric temperatures as well as atmospheric CO2 have been gradually and erratically falling for significant portions of Earth’s history, but not in unison. Successive ice ages are gradually and unevenly becoming ever colder.

There is evidence that very minor changes in the incidence of sunlight on Earth can and have resulted in plunging Earth and all its living cargo into new ice ages.

Earth is currently in an interglacial period, and based on previous ice ages and the changes in global temperatures during this interglacial period, we are now near the end of it.

Coming in from the cold?

Coming in from the cold?


As this report suggests, when Trump and co. take over: ‘the debate over global warming might shift. Until now, it’s normally portrayed as enlightened scholars vs. anti-science simpletons. A more open debate could shift the discussion to one about global warming’s extent and root causes.’
Not before time, and it’s not just the ‘discussion’ that needs shifting.

H/T GWPF

In the world of climate science, the skeptics are coming in from the cold. Researchers who see global warming as something less than a planet-ending calamity believe the incoming Trump administration may allow their views to be developed and heard.

This didn’t happen under the Obama administration, which denied that a debate even existed. Now, some scientists say, a more inclusive approach – and the billions of federal dollars that might support it – could be in the offing.

“Here’s to hoping the Age of Trump will herald the demise of climate change dogma, and acceptance of a broader range of perspectives in climate science and our policy options,” Georgia Tech scientist Judith Curry wrote this month at her popular Climate Etc. blog.

This is from US CLIVAR. If their graph is to be believed the ocean heat content went up by a factor of about 6 between 1980 and 2012. The title of their paper is ‘The global warming hiatus: Slowdown or redistribution? (Earth’s Future)’. Of course ‘missing heat hiding in the ocean’ is not exactly a new claim from climate alarm theorists.

Atmospheric greenhouse gases have continued their steady increase in the new century. Logically, one would expect that global mean surface temperature (GMST) would also continue to increase in the same fashion as experienced in the latter decades of the 20th century.

However, between 1998 and 2013 GMST actually plateaued with much smaller increases than the average over the last 60 years and labeled the “global warming hiatus.” The fact that this slowdown in GMST increase was not predicted by most climate models has led some to question the steady increase in heat predicted under increased greenhouse gas conditions.

Global warming takes the day off in Colorado

Global warming takes the day off in Colorado


Outdoor protesting in December in the Northern Hemisphere can have its drawbacks, as The Daily Caller describes. Maybe add embarrassment to the list when you’re claiming that humans are making the world warmer.

A small group of global warming activists protesting oil and gas drilling outside the Department of Interior office in Colorado Thursday morning were met with bitter cold weather and snow.

About 10 “Keep It In The Ground” activists waved signs next to a busy road in the Denver area, calling for the Obama administration to stop issuing leases so companies can drill on public lands.

Activists say drilling only exacerbates global warming. The irony, however, is activists stood outside in about 4 inches of snow with temperatures hovering in the 20s — in degrees Fahrenheit.

From GWPF:

In 2008, I was one of the many members of both houses who unquestioningly voted for Ed Miliband’s Climate Change Act, with its legal commitments to rapidly decarbonise the British economy. The measure was not properly costed (now forecast at upwards of £360bn by 2050). I had not studied the Bill. This seemed a noble, if eye-wateringly ambitious, project: to ‘save the planet’. Who could object to that?

Another round of claims and counter-claims about climate is underway as natural variation takes its course. Talk of records often relates only to the satellite era.
H/T GWPF

Global average temperatures over land have plummeted by more than 1C since the middle of this year – their biggest and steepest fall on record, reports David Rose in The Mail on Sunday. 

According to satellite data, the late 2016 temperatures are returning to the levels they were at after the 1998 El Niño. The news comes amid mounting evidence that the recent run of world record high temperatures is about to end.

Useful comparison of ENSO and (supposed) CO2 influences on climate by kenskingdom. ENSO correlations look significant, whereas CO2 – nothing to report really.

In this post I use the Multivariate ENSO Index (MEI) supplied by NOAA at http://www.esrl.noaa.gov/psd/enso/mei/index.html and lower tropospheric temperature data supplied by UAH to show how much of temperature variation over the past 20 years is due to ENSO and how little is due to CO2.  I will keep words brief and let graphics do the talking.

Firstly, here is the MEI data from 1950:

Fig. 1:  Monthly MEI from 1950

mei monthly

As an aside, this is how it compares with SOI data.  The SOI is inverted and both are scaled for comparison.

Fig. 2:  MEI compared with SOI inverted

mei vs soi

Now compare scaled MEI with Global UAH:

Notice tropospheric temperatures appear to lag the MEI by some 5 months:

Notice both datasets are noisy, and there is a clear discrepancy in the early 1990s.  12 month running…

We’re supposed to believe that CO2 levels determine global temperature, but here in plain sight is obvious evidence that they don’t.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Roy Spencer has news of a big drop in satellite temperatures last month:

NOTE: This is the fifteenth monthly update with our new Version 6.0 dataset. Differences versus the old Version 5.6 dataset are discussed here. Note we are now at “beta5” for Version 6, and the paper describing the methodology is still in peer review.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2016 is +0.34 deg. C, down 0.21 deg. C from the May value of +0.55 deg. C (click for full size version):

UAH_LT_1979_thru_June_2016_v6

This gives a 2-month temperature fall of -0.37 deg. C, which is the second largest in the 37+ year satellite record…the largest was -0.43 deg. C in Feb. 1988.

In the tropics, there was a record fast 2-month cooling of -0.56 deg. C, just edging out -0.55 deg. C in June 1998 (also an El Nino…

Fearless Physics from Dr. Salby

Ron Clutz features Dr Murry Salby’s new textbook ‘Physics of the Atmosphere and Climate’ which calls into question the narrow-minded thinking behind claims that carbon dioxide is a powerful climate driver, to the virtual exclusion of other factors.

Science Matters

“Fearless Felix” Baumgartner ascended to the stratosphere and stepped into the void from 24.2 miles above the Earth. His speed during the fall reached Mach 1.24, and the Austrian adventurer nailed the landing. October 14, 2012 Wired 

Introduction
Murry Salby is also totally committed to the atmosphere. He is a scientist with such deep and broad knowledge of atmospheric physics that he has written multiple textbooks on the subject. And yet he is not fearful for the future of our climate system, in contrast to many of his colleagues. By stepping away from “consensus” climate alarms, he has shown unusual courage by speaking plainly about the atmosphere and climate, despite attempts to silence him.

Dr. Salby’s latest textbook is entitled Physics of the Atmosphere and Climate (here). I got a copy and have been reading in it to understand where he comes down on various issues related to climate…
