The headline is straight from the research press release. Of course that suggests alarmists can only hope to blame human-caused ‘carbon emissions’ for the other half of any recent warming, by invoking their own version of a planetary ‘greenhouse effect’.
– – –
Ozone-depleting substances (ODSs) may be responsible for nearly half of Arctic warming from 1955 – 2005, according to a study published in Nature Climate Change.

These findings highlight an unrecognized source of twentieth-century Arctic climate change.

ODSs – halogen compounds that destroy the protective layer of ozone in the upper atmosphere – were used as propellants, refrigerants and solvents during the twentieth century.

Since the 1987 Montreal Protocol, ODS emissions have been curbed, and the ozone layer is now in slow recovery.

Earth and climate – an ongoing controversy

Regular Talkshop contributor and climate expert Ian Wilson highlights the lack of scientific logic in the idea that carbon dioxide (CO2) somehow controls climate variations in the modern era. This has led to such absurdities as claims of a ‘climate emergency’ and demands to stop using oil, gas, and coal, with many countries actively pursuing policies along those lines.

Climate scientists insist that rising atmospheric CO2 concentrations (measured in parts per million or ppm) are forcing the Earth’s atmospheric and oceanic temperatures to increase, writes Ian Wilson.

They base their claim on the premise that CO2 is a greenhouse gas that prevents infrared light from escaping the Earth’s atmosphere.

They propose that the trapped infra-red radiation results in a net gain in the energy that is stored in the Earth’s atmosphere (~ 2 %) and oceans (> 90 %).

Dr. Peter Ward explains at The Hill Greenhouse gases simply do not absorb enough heat to warm Earth Excerpts in italics with my bolds.

Science is not done by consensus, by popular vote, or by group think. As Michael Crichton put it: “In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.”

The drive to demonstrate scientific consensus over greenhouse-warming theory has had the unintended consequence of inhibiting genuine scientific debate about the ultimate cause of global warming.

Believers of “the consensus” argue that anyone not agreeing with them is uninformed, an idiot or being paid by nefarious companies. The last thing most climate scientists want to consider at this point, when they think they are finally winning the climate wars, is the possibility of some problem with the science of greenhouse-warming theory.

Davos


Many of the usual suspects of high finance and politics will be flying in by private jet to scope out the financial opportunities and rub shoulders with fellow power brokers. More hyped-up climate fear equals more potential profit, and never mind the ’emissions’.

An impatient demand for the world to work harder to counter “climate change” will top the agenda at the World Economic Forum (WEF) annual meeting next month in Davos, Switzerland, says Breitbart News.

Organizers expect some 3,000 corporate and government representatives to fly in from around the world to broach climate issues at the luxury ski resort, with a squadron of some 1700 private jets providing transport for the bulk of the attendees.

Link to third video: “A Tsar is Born”

Science Matters

GWPF published today a letter from the late Sir Antony Jay, co-creator of Yes, Minister and Yes, Prime Minster, attacking the BBC for its blatant bias on climate change 8 years ago.  It seems timely to repost the final episode from the last season addressing the topic of global warming/climate change.  As you see, climate politics have not changed very much.

Part 1 of the program is here:

Part 2

Previously I posted this:

A humorous look at why the global warming campaign and the triumphal Paris COP make sense.

Yes Minister explains it all in an episode from 2013.

h/t to Peter S.

This is an all-too-realistic portrayal of political climatism today.

Then I realized that BBC had blocked the viewing of the video.  So I sought and found the subtitles for Yes Prime Minister 2013, Episode 6, “A Tsar is Born”.  That final episode for the series began with…

An eye-opener for wind turbine supporters, and everyone else who has to pay for them via taxes and power bills.

PA Pundits - International

By Duggan Flanakin ~

Wind turbines continue to be the most controversial so-called “renewable” energy source worldwide. Yet, you say, wind is surely renewable. Really? Sure, the wind blows intermittently, but what if wind power actually contributes to global warming?

While the wind itself may be “renewable,” the turbines surely are not. Arcadia Power reports that the widely used GE 1.5-megawatt (MW) turbine, is a 164-ton monster with 116-foot blades on a 212-foot tower that weighs another 71 tons. The Vestas V90, which has 148-foot blades on a 262-foot tower, has a total weight of about 267 tons. That is just ONE TURBINE!

How are these giants constructed? The U.S. Geological Survey, citing the National Renewable Energy Laboratory, states that turbines are predominantly made of steel (which comprises 71 to 79 percent of total turbine mass), fiberglass, resin, or plastic (11 to 16 percent), iron or cast iron (5 to…

Omega blocking highs can remain in place for several days or even weeks [image credit: UK Met Office]


Another day, another attempt at a climate scare story. That’s a well-identified pattern too. But is this jet-stream pattern really ‘newly’ identified, or was it described by NASA nine years ago? Meteorology uses the term omega block. Which side of the block a region is on determines whether it’s warmer or colder than normal for the duration.

Scientists have identified systematic meanders in the globe-circling northern jet stream that have caused simultaneous crop-damaging heat waves in widely separated breadbasket regions-a previously unquantified threat to global food production that, they say, could worsen with global warming.

The research shows that certain kinds of waves in the atmospheric circulation can become amplified and then lock in place for extended periods, triggering the concurrent heat waves, reports Phys.org.

Affected parts of North America, Europe and Asia together produce a quarter of the world food supply. The study appears this week in the journal Nature Climate Change.

Climate conference transport


Where’s the logic? Nearly all these folk arrived in Madrid thanks to fossil fuels. They accepted sponsorship – without which there wouldn’t be a conference – from companies that deal in fossil fuels. But now they want to whine about who and what they’re depending on.

Oil and gas groups were accused Saturday of seeking to influence climate talks in Madrid by paying millions in sponsorship and sending dozens of lobbyists to delay what scientists say is a necessary and rapid cut in fossil fuel use.

A day after tens of thousands marched in the Spanish capital demanding climate action, seven environmental groups raised concerns to AFP over the role of fossil fuel representatives at the COP25 summit, reports Phys.org.

So IPCC climate theory now means that cleaner air is more of a problem. Classic.

The relationship between aerosols (particulate matter) and their cooling effect on the Earth due to the formation of clouds is more than twice as strong as was previously thought, reports Phys.org.

As the amounts of aerosols decrease, climate models that predict a faster warming of the Earth are more probable.

These are the conclusions of researcher Otto Hasekamp from SRON Netherlands Institute for Space Research, who published the results in Nature Communications. He carried out his research together with Edward Gryspeerdt from Imperial College London, and Johannes Quaas from Leipzig University.

Of course they are pushing the usual doom and gloom messages based on dubious greenhouse gas theories, but a glimmer of light perhaps is that they accept the Earth has warmed and cooled in the past due to unknown factors. They in effect admit the obvious, namely that attribution of climate change to humans in some, or any, degree cannot be quantified at present. But the bluffing goes on.

As the pace of global warming outstrips our ability to adapt to it [Talkshop comment – allegedly], scientists are delving deep into the distant past, hoping that eons-old Antarctic ice, sediments and trees chart a path to navigate our climate future, says Phys.org.

“What interests us is to understand how the climate works,” says Didier Roche of France’s National Centre for Scientific Research (CNRS).

At the Laboratory for Climate and Environment Sciences (LSCE), just outside Paris, the aim is to establish a comprehensive record of climate change dating back hundreds of thousands of years, to chart the repeated warming and cooling cycles the Earth has gone through and to try to understand what drives them.

Earth and climate – an ongoing controversy


But groupthink and the fog of constant alarmist propaganda makes it hard for many people to see through to the mundane truth, that their emotions are being exploited in ways that have little or nothing to do with the climate.

At a press conference on Wednesday (20th November), the European Parliament was told: ‘there is no climate emergency’.

One MEP became emotional and accused the organisers of ‘collective manslaughter’ on future generations, reports The GWPF.

Hard to say which is the greater fantasy: the belief in human-caused climate change due to trace gases, or the prescribed attempts to ‘tackle’ the imagined problem. Demand for energy is rising worldwide, meaning attempts to restrict its supply look doomed. One analyst says: “Despite more than two decades of climate policy making, fossil fuel production levels are higher than ever.”

There’s a huge gulf between ambition and reality, reports DW.com.

The world is on track to produce far more fossil fuels than permissible to meet its target of limiting global warming to at most 2 degrees Celsius, and ideally 1.5 degrees C.

That’s the conclusion of the Production Gap Report, created from leading research institutions together with the United Nations Environment Programme (UNEP).

Earth and climate – an ongoing controversy


Below are a few quotes from the GWPF article. More discussion with graphics via the link. Is the handbrake about to be re-applied to so-called human-caused warming of the planet, in contradiction of alarmist ‘projections’?

Back around 2014 many people, me included, were commenting on the discrepancy between climate models and observations [writes Ross McKitrick].

The IPCC itself in the 5th Assessment Report (2013) noted that out of 114 model runs, 111 had overstated observed warming since the late 1990s.

By what known physics could a few molecules of carbon dioxide upset the jet stream? A meteorologist is not impressed by such claims.

By Chris Martz | November 9, 2019
INTRODUCTION Just when wildfires weren’t enough, we now have people blaming cold weather on a warming climate, which seems quite contradictory.

In light of the Arctic outbreak in forecast this coming week, people like Phil Plait (who has since blocked me) took to Twitter (Figure 1) to claim that man-made climate change is causing frigid, Arctic air to be displaced south into the United States, Europe, and Asia.

His argument, which is supported by some climate scientists, suggests that man-made global warming causes the polar jet stream to destabilize causing it to become wavy rather than zonal, sending Arctic air southward into the mid-latitude regions.

He also stated that without global warming, the polar air would stay near the north pole.

Both of these claims are exactly backwards from reality and are not supported by weather dynamics, the global warming theory, or statistical observations in long-term temperature data.

All you’re likely to hear from promoters of climate alarm are ‘balance of probability’ arguments.

“The influence of mankind on climate is trivially true and numerically insignificant.” – Dr Richard Lindzen

So you say the science is settled, you trust 97% of climate scientists and you call me a denier, writes Richard Treadgold @ Climate Conversation.

It’s hardly surprising and I sympathise with that view—we’ve been badgered over it for years.

But all we sceptics do is ask you, “What’s the evidence?” There’s no denial in that, so what’s your answer? If the science really is settled, what evidence is it based on?

Interesting question, but we’re still left with another one: what causes the super El Niños?

PA Pundits - International

By David Wojick, Ph.D. ~

In a recent CFACT article, climate expert Joe Bastardi says super El Niños have caused all the atmospheric warming since satellite measurements began in 1978. I suggested this two years ago in a CFACT article titled “No CO2 warming for the last 40 years?” Now Joe has confirmed it.

The focus of Joe’s long article is that these super El Niños are natural.

Most importantly, here is Joe’s picture of the 1998-2000 super El Niño step up in global temperatures, with nothing but 15 to 20 year pauses on either side:

My description of this big step up, posted two years ago, is here.

There is little to no CO2 warming in the entire satellite record! Just a step up warming due to the super El Niño 20 years ago. I told you so. We may now have…

The original headline for this article was: ‘Climate warming promises more frequent extreme El Niño events’. But since nothing is ‘promised’ it seems to rely too much on assumptions. For example, we are yet to see the full effects, if any, of the current very low solar minimum and the ‘quiet’ solar cycle expected to follow it.

El Niño events cause serious shifts in weather patterns across the globe, and an important question that scientists have sought to answer is: how will climate change affect the generation of strong El Niño events?

A new study, published today in the Proceedings of the National Academy of Science by a team of international climate researchers led by Bin Wang of the University of Hawaii’s International Pacific Research Center (IPRC), has an answer to that question, reports Phys.org.

What if anything can ‘uncertain predictions’ about the climate tell us that might be worth taking seriously? Excitable headline-chasing fearmongers do nothing to help, especially when proved wrong.

The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness, reports ScienceDaily.

The more specific climate scientists are about the uncertainties of global warming, the more the American public trusts their predictions, according to new research by Stanford scholars.

But scientists may want to tread carefully when talking about their predictions, the researchers say, because that trust falters when scientists acknowledge that other unknown factors could come into play.

In a new study published in Nature Climate Change, researchers examined how Americans respond to climate scientists’ predictions about sea level rise.

Another cold shower of reality for misguided climate zealots.

Thirty-seven globally prominent scientists representing the International Journal of Engine Research have published an open-access editorial addressing the future of the Internal Combustion Engine, and stressing the importance for continued development of more efficient and even lower-emitting technologies.

The article provides an assessment of the state of power generation in the world today, and provides analyses of productive directions for the future, says Green Car Congress.

The editorial addresses important issues in the current politically charged discussions of global warming and climate-change alarm.

Another setback for know-it-all climate alarmism, but a win for resilient nature.

For the first time ever, scientists have found corals that were thought to have been killed by heat stress have recovered, a glimmer of hope for the world’s climate change-threatened reefs, says Phys.org.

The chance discovery, made by Diego K. Kersting from the Freie University of Berlin and the University of Barcelona during diving expeditions in the Spanish Mediterranean, was reported in the journal Science Advances on Wednesday.

Kersting and co-author Cristina Linares have been carrying out long-term monitoring of 243 colonies of the endangered reef-builder coral Cladocora caespitosa since 2002, allowing them to describe in previous papers recurring warming-related mass mortalities.

“At some point, we saw living polyps in these colonies, which we thought were completely dead,” Kersting told AFP, adding it was a “big surprise.”
