Since climate scares were first sponsored by governments, neither the theory of man-made causality nor the evidence for it have improved. Models have failed to predict what actually happened. Time’s almost up for alarmists.

Fool Me Once Shame on You,
Fool Me Twice, Shame on Me.

It was just 30 years ago this week that James Hansen, the former NASA scientist who testified before the Senate Energy and Natural Resources Committee during a prolonged heat wave, which” he described as a climate event of cosmic significance.” Just to be sure he arranged for the meeting room to be warmer than usual. He expressed to the senators “his high degree of confidence” in “cause-and-effect relationship between the greenhouse effect and observed warming.”

There was an accompanying paper in the Journal of Geophysical Research, and it ignited a world wide panic that continues today about the energy structure of the entire planet. So 30 years on we can pause and take a look at just how well his predictions have turned out, and check on how we are doing.

Mr. Hansen’s testimony described three possible…

Borrowing Hollywood titles like ‘a clear and present danger’ isn’t going to overcome the fact that colourful predictions made about the climate by modellers and climate alarmists in general have failed to materialise. BBC – take note.

Republican senators asked federal investigators to look into whether or not several National Science Foundation (NSF) grants broke federal law, including funding projects lawmakers sought to “influence political and social debate” on global warming.

NOT A LOT OF PEOPLE KNOW THAT

GWPF carry the story of a letter recently sent to the president of the Geological Society by a group of concerned current and former members:

The President
Geological Society of London

Dear President

We are writing as a group of concerned primarily geoscientists, half of whom are or were Fellows, (names and affiliations listed below). Our concern is that the Society’s position on Climate Change (aka Anthropogenic Global Warming or AGW), is outdated and one-sided, and is distracting attention and funding from real issues of pollution such as plastic and other noxious industrial and domestic waste. To address this, we proposed to Colin Summerhayes that the 2010 and 2013 GSL Position Papers be posted on the Energy Matters blog, so that all sides of the discussion could be aired; and we are very grateful to Colin for effecting and taking part in this (http://euanmearns.com/the-geological-society-of-londons-statement-on-climate-change/).

Has the media been trying to bury bad news here? Embarrassingly bad news for its enthusiasm for supposed man-made global warming, that is.

Last week a team of researchers from the UK Met Office, the University of East Anglia, the University of Gothenburg, the University of Southern Queensland and the Sorbonne published in the journal Science Advances an interesting paper showing that the recent much debated and researched 21st century “slowdown” in global surface temperatures was real and could be explained by reduced solar activity and increased volcanic counteracting climate forcing from greenhouse gases.

It achieved almost no media coverage despite being published in a high profile journal, writes Dr David Whitehouse @ The GWPF.

If ‘slowdowns’ in global average temperatures can be natural, why not ‘speed-ups’ as well? Recent global temperature patterns correlate very poorly, if at all, with changes in the trace gas CO2 as required by IPCC-supporting climate theorists.

A team of researchers from the U.K., Sweden and Australia has found that three periods of global warming slowdown since 1891 were likely due to natural causes rather than disruptions to the factors causing global warming, reports Phys.org.

In their paper published on the open access site Science Advances, the group describes their study of global mean surface temperatures (GST) since the late 19th century and what they found.

Despite warming due to atmospheric trace gases being a racing certainty according to the IPCC and like-minded theorists, evidence of it is getting ever harder to find.

Science Matters

Presently sea surface temperatures (SST) are the best available indicator of heat content gained or lost from earth’s climate system.  Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy.  Measuring water temperature directly avoids distorted impressions from air measurements.  In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates.  Eventually we will likely have reliable means of recording water temperatures at depth.

Recently, Dr. Ole Humlum reported from his research that air temperatures lag 2-3 months behind changes in SST.  He also observed that changes in CO2 atmospheric concentrations lag behind SST by 11-12 months.  This latter point is addressed in a previous post Who to Blame for Rising CO2?

The May update to HadSST3 will appear later this month, but in the meantime we can look at lower troposphere temperatures (TLT) from UAHv6…

To what extent can courts tell governments what so-called ‘climate policies’ they should be adopting? Isn’t there a burden of proof in such cases? Appeal verdict awaited – eventually.

The Dutch government on Monday appealed against a landmark 2015 court ruling which ordered it to slash greenhouse gases by a quarter by 2020, reports Phys.org.

“The current government is already extraordinarily active in terms of climate,” lawyer Bert-Jan Houtzagers told the Hague Appeals Court.

Wood burner [image credit: BBC]


That point was probably reached ten years ago when the UK’s notorious Climate Change Act was passed. Now we have things like this “Scandal of ‘killer’ wood burning stoves”.

The bitter truth is that these fiascos caused by our obsession with wood-burning are just a part of a larger disaster that taints almost every green scheme governments have foisted on Britain, writes Christopher Booker in the Daily Mail.

The Government earned plaudits from the green lobby yesterday for its new plan to crack down on the craze for wood-burning stoves.

As the Mail reported on its front page, the stoves chuck out lethal pollution, particularly from wet wood, and contribute to thousands of early deaths from lung and heart disease.

But hang on!

A lay person’s view of the global warming furore. When we hear ‘unprecedented’ it usually turns out to mean ‘since about 1979’, which obviously leaves out most of Earth’s history.

American Elephants

You have heard the wailing and screaming about President Trump’s exit from the Paris Climate Accords, but do you understand that the agreement, never ratified by the U.S. government (NOT a treaty) accomplished nothing at all to modify or change the climate. The climate of the earth has been changing mildly for millions of years, and there is no unprecedented Global-Scale modern warming. The “Accords” were designed to transfer large amounts of wealth from the rich nations to the poor nations, ostensibly to allow them to save themselves from that non-existent unprecedented warming.

There are two kinds of climate science that we are dealing with. One is based on satellite measurements and thermometer readings and recorded history. The other is based on computer programs, based, I believe on computer programs that were designed to forecast what the financial markets were going to do. They took what they knew about the…

The headline from the source should perhaps mention that those ‘variations’ can include ‘no global warming trend’, or hiatus, as explained below.

New research has shown that natural variations in global mean temperature are always forced by changes in heat release and heat uptake by the oceans, in particular the heat release associated with evaporation, reports Phys.org.

Analysing data from six climate models that simulated future climate change scenarios for the last International Panel for Climate Change (IPCC) Report, which appeared in 2014, University of Southampton Professor Sybren Drijfhout has shown that in all cases variations in global mean temperature were correlated with variations in heat release by sensible and latent heat.

This BBC report seems unaware that a study in 2014 found that parts of the Thwaites Glacier are subject to melting due to subglacial volcanoes and other geothermal “hotspots”. The existence of this group of volcanoes has long been known.

British and American scientists will assess the stability of one of Antarctica’s biggest ice streams, reports BBC News.

It is going to be one of the biggest projects ever undertaken in Antarctica.

UK and US scientists will lead a five-year effort to examine the stability of the mighty Thwaites Glacier.

As the Senator says of the Paris climate agreement: ‘It has no teeth’. But if it did have teeth there would surely be far more resistance to signing it.

Louisiana Sen. Bill Cassidy noted one obvious problem Thursday with French President Emmanuel Macron’s recent clarion call for the U.S. to stay connected to the Paris Climate agreement, reports The Daily Caller.

Exempting China and India from abiding to the non-binding deal is one of the main reasons why greenhouse gas emission are pitching upward, Cassidy said in an interview with Fox News’ Brian Kilmeade.

Environmental rules in the U.S. are causing companies to shift production to countries not tethered to the accord’s strict provisions.

Leaving aside whether ‘climate sensitivity’ (to carbon dioxide) is a valid concept in the first place, it’s been obvious for a while that climate modellers have seriously overestimated the actual level of any warming that has occurred in recent years. If that doesn’t suggest to them that something is wrong, what would?
H/T The GWPF

London, 24 April — A paper just published by the Journal of Climate concludes that high estimates of future global warming from most computer climate simulations are inconsistent with observed warming since 1850. The implication is that future warming will be 30 to 45% lower than suggested by the simulations.

The study estimates climate sensitivity — how much the world will warm when carbon dioxide levels increase* — from changes in observed temperatures and estimates of the warming effect of greenhouse gases and other drivers of climate change, from the mid/late 19th century until 2016.

The paper also addresses previous criticisms of the methodology used, finding that these are unfounded.

From the GWPF’s own preamble to the Humlum report, quoting the professor:
“It is clear that temperatures in the troposphere are continuing to diverge from surface temperatures. In other words, they are warming more slowly than global warming theory says they should. The contrast with theory is even more marked in the stratosphere, where temperatures have barely changed for 23 years. We still have much to learn about the climate.”

There’s data, and then there’s interpretation of the data. But what the Northern Hemisphere weather has delivered is not what many CO2-fearing climate experts were expecting, despite some claims to the contrary.

The new Arctic Now product shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change.

Is this how it works? [image credit: politics.ie]


An obvious problem with studies like this is that as soon as natural climate variation is invoked – to explain the lack of expected warming from so-called greenhouse gases – the argument that such gases could be a dominant factor in climate processes is then severely weakened to say the least. It is in effect an admission that such variations could cause warming as well as cooling. How long can a ‘hiatus’ last before it becomes the status quo?

Reinforcement of Climate Hiatus by Decadal Modulation of Daily Cloud Cycle
– By Jun Yin and Amilcare Porporato, Princeton University
H/T The GWPF

Based on observations and climate model results, it has been suggested that the recent slowdown of global warming trends (climate hiatus), which took place in the early 2000s, might be due to enhanced ocean heat uptake.

Here we suggest an alternative hypothesis which, at least in part, would relate such slowdown to unaccounted energy reflected or re-emitted by clouds.

The role of the lowest solar cycle for at least a century is mostly ignored by believers in man-made global warming. There are signs of climate change, but not necessarily the kind they expect.

Not for the first time in recent years, Europe has descended into a deep freeze while the Arctic experiences record high temperatures, leaving scientists to ponder the role global warming may play in turning winter weather upside down, says Phys.org.

The reversal has been dramatic.

France’s President Macron at Davos


France’s virtue-signalling anti-coal pledge may sound grand, but as the report points out it ‘only has three power plants that burn coal’, providing 1% of its electricity. Another potential problem for France is the inflexibility of nuclear power, which is not suitable for rapid ramping up and down in response to changes in demand and/or short-term fluctuations in renewable energy. In February 2017 the German nuclear plant at Brokdorf was taken offline after the operation of the plant in “load-following” mode had contributed to unexpected oxidation of its fuel rods.

France failed to meet its global warming target, as The Daily Caller reports.

BERLIN—Germany is missing its European climate targets and will have to pay for rights to emit greenhouse gases due to polluting vehicles, farms and buildings, the government said Wednesday, an embarrassing admission for Chancellor Angela Merkel who had once put energy transformation at the forefront of her policies.

Davos


It hasn’t been this bad since the 1999-2000 meeting. As President Trump might say, they could do with some of that good ol’ global warming. Then again, if you go to a Swiss ski resort in January…

The global economy and geopolitical tensions are taking a back seat to a more immediate problem at this year’s Davos summit of political and business leaders: heavy snow is burying the venue, as Reuters reports.

High in the Swiss alps on Monday, on the eve of the opening sessions, many of the roughly 3,000 delegates struggled to reach the ski resort. Part of the main train line into Davos had been buried in snow over the weekend, forcing people onto buses, and helicopters were disrupted by poor visibility.

Some pre-summit meetings were canceled or delayed as the first waves of delegates waded through snow-blanketed streets with luggage, looking for their hotels, or had to wait for road crews to dig their limousines out of drifts.
