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


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

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

Now compare scaled MEI with Global UAH:

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…

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…

Are we anywhere close to really understanding the strength of natural climate variation and how it works?

We can easily overlook that most temperature measurements are taken on land, but over 70% of the Earth’s surface is deep water.

Frederick Colbourne investigates.

Geoscience - Environment

Climate Research Unit, University of East Anglia

The Climatic Research Unit (CRU) was established in the School of Environmental Sciences (ENV) at the University of East Anglia (UEA) in Norwich in 1972.

The CRU has collected, collated and archived global climate data for over 40 years.

CRU temperature data

In 1987, the American Meteorological Society published a paper by Stanley Grotch of the Lawrence Livermore National Laboratory, University of California, that assessed the robustness of the CRU dataset for land and other datasets.

Monthly Weather Review, Volume 115 No. 7, July 1987, ISSN: 0027-0644; eISSN: 1520-0493

Abstract

Three data bases of gridded surface temperature anomalies were used to assess the sensitivity of the average estimated Northern Hemisphere (NH) temperature anomaly to: 1) extreme gridpoint values and 2) zonal band contributions. Over the last 100 year, removal of either the top or bottom 10% of the gridpoint anomalies in any year changes…

Looks like Antarctic climate warming scares have gone into a death spiral. What a shame after all those man-made attempts at doom and gloom, and harsh attacks on critics.
H/T GWPF

A group of scientists have just published a study that tries to explain why Antarctica isn’t warming as predicted, and its ice isn’t melting as climate models say it should be.

As Reuters reports, the researchers identified flows of cold, deep water as the primary reason our models are failing down there: A persistent chill in the ocean off Antarctica that defies the global warming blamed for melting Arctic ice at the other end of the planet is caused by cold waters welling up from the depths after hundreds of years, scientists said on Monday.

Indulging in climate fantasy can lead to some strange ideas, like this one. The idea of articles like this is presumably to infect the minds of the gullible with thoughts of impending crisis, where none should exist.

With sea levels rising and Antarctica’s temperatures well below freezing, some people [i.e. the authors?] have raised the question: What would happen if we took water out of the oceans and pumped it onto the icy continent to freeze?

A group of scientists put that question to the test in a new study that explores the physical possibility and economic feasibility of geoengineering climate solutions in the future.

slowdown
Climate scientist Ed Hawkins comments on the paper of which he is one of the co-authors. Others include Ben Santer and Michael Mann.

It has been claimed that the early-2000s global warming ‘slowdown’ or ‘hiatus’, characterized by a reduced rate of global surface warming, has been overstated, lacks sound scientific basis, or is unsupported by observations. The evidence presented in a new commentary in Nature Climate Change by Fyfe et al. contradicts these claims.

It may only be the conclusion of one expert, but it makes a change from the usual tidal wave of evidence-light negative assertions about the potential future of our Earth. He said it was ‘extremely difficult’ to find a correlation between carbon dioxide levels and temperature trends.

The global average temperature is likely to remain unchanged by the end of the century, contrary to predictions by climate scientists that it could rise by more than 4C, according to a leading statistician.

In between the climate scare stories come the excuses for the non-events the scares were about. How the world becomes ‘increasingly hot’ with little or no increase in average temperatures is not addressed.

As glaciers melt due to climate change, the increasingly hot and parched Earth is absorbing some of that water inland, slowing sea level rise, NASA experts said Thursday.

Satellite measurements over the past decade show for the first time that the Earth’s continents have soaked up and stored an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, the experts said in a study in the journal Science. This has temporarily slowed the rate of sea level rise by about 20 percent, it said.
