Climate conference transport


It takes more than a ‘climate emergency’ to keep climatologists on the ground. It’s almost like they don’t take their own theories seriously, although professors not travelling isn’t going to make any difference anyway. Do as they say, not as they do.

Climate change researchers, especially professors, fly more than other researchers—but are also more likely to have taken steps to reduce or offset their flying, a new study has found.

Climate change researchers, especially professors, fly more than other researchers—but are also more likely to have taken steps to reduce or offset their flying, a new study has found.

The large, international survey of more than 1,400 university researchers was carried out by the UK Centre for Climate and Social Transformation (CAST), which is coordinated by Cardiff University, reports Phys.org.

A follow-up experiment with more than 350 researchers found that providing information about the impacts of aviation and support for workplace policies increases intentions to fly less.

The large-scale study—the first of its kind to survey climate academics about their travel for conferences, fieldwork and meetings—is published in the journal Global Environmental Change.

Director of CAST Professor Lorraine Whitmarsh, who led the study, said the findings were “unexpected” but said it also suggested “knowledge alone is not enough” to tackle global warming.

Another day, another scare. The claim this time is that the increasing demand for electrically driven cooling — air con, powered fans etc. — will drive up the dreaded ’emissions’, leading to untold future discomfort one way or another.
– – –
Past research suggests growing international demand for cooling has the potential to drive one of the most substantial increases in greenhouse gas emissions in recent history, says Phys.org.

A new study, led by the University of Oxford and published today in Nature Sustainability, sets out a framework for delivering sustainable cooling.

It also examines cooling needs in the context of sustainable development, and finds that this is a global blind spot.

“Cooling is essential to human well-being and health, from the food we eat, to the storage of medicine, to how comfortable and productive we are at home, school or the office,” says Dr. Radhika Khosla, senior researcher at the Smith School of Enterprise and the Environment, and principal investigator of the Oxford Martin Program on the Future of Cooling.

But, Dr. Khosla says, “The global community must commit to sustainable cooling, or risk locking the world into a deadly feedback loop, where demand for cooling energy drives further greenhouse gas emissions and results in even more global warming.”

Since Arrhenius was mentioned in the ‘conversation with Roger Pielke Senior’ post this week, let’s look at his science efforts a bit more closely — with Ron Clutz.

Science Matters

“Those who cannot remember the past are condemned to repeat it.”–George Santayana 1905

Interesting that Svante Arrhenius was elevated as the founder of AGW belief system. He was ignored for many decades after Knut Ångström and his assistant Herr Koch showed that reducing CO2 concentrations did not affect the amount of IR absorbed by the air. That’s almost as interesting as discovering that shutting down the global economy over fear of Covid19 has little effect on atmospheric CO2 concentrations.

As a fellow Scandinavian, Ångström agreed with Arrhenius that his projected warming would be a good thing, even in the lower estimates Svante made later on. Still, Ångström had two objections to Arrhenius’ conjecture about global warming from increasing CO2. In 1900, Herr J. Koch, laboratory assistant to Knut Ångström, did not observe any appreciable change in the absorption of infrared radiation by decreasing the concentration of CO2 up to a…

The only viable option for carbophobes is significant degrowth (their term) according to this article. With present delusional plans to control global warming the numbers just don’t add up for ‘greenhouse gas’ obsessives, so even greater futile sacrifices are demanded.

Shifting to electric vehicles while maintaining current travelling habits will not deliver emissions reductions required by the European Green Deal and Paris Agreement.

The European Green Deal sets ambitious targets for decarbonising the European economy.

This includes a European Commission proposal to reduce greenhouse gas emissions by at least 55 percent by 2030, with the European Parliament’s Environment Committee demanding a more ambitious 60 percent cut.

The EGD also calls for the EU to become carbon-neutral by 2050.

A new analysis of global air temperature by researchers from Tongji University in Shanghai has cast light on the much debated recent hiatus in global temperature, says Dr David Whitehouse @ The GWPF.

Writing in the Journal of Earth Science the Chinese scientists say there was a rapid rise in global mean surface air temperature after the late 1970s but that this stalled and there was a relative stagnation and even slight cooling that lasted for about 15 years (1998–2012).

They add that even though the slowdown was acknowledged by the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) and termed as a hiatus (IPCC, 2013) there was a debate in the scientific community about whether there was a hiatus in global warming or not.

The researchers believe that the debate about the global warming hiatus poses a substantial challenge to our understanding of the global climate response to anthropogenic greenhouse gas emissions and natural variability.

Countdown to another big climate yawnfest 🥱

PA Pundits - International

By Peter Murphy~

Former Vice President turned nine-figure millionaire, Al Gore, long a global warming celebrity, will be among several speakers next month for a series of “TED Talks” to launch “Countdown,” which is a global initiative to deal with the “climate crisis.” The Countdown is pushing to reduce global carbon emissions in half by 2030 “in the race to a zero carbon world …that is safer, cleaner and fairer for everyone” (emphasis mine).

No one is against “safer, cleaner and fairer” in the abstract, which is why such terms are used incessantly in commercials, and by interest groups, politicians, salespeople and hucksters alike. I’m especially curious about that word “fairer” when it comes to climate activism. “Fairness” also is a subjective term; one person’s definition of fair is not necessarily another person’s.

From a political or policy standpoint, fairness is about who gets and who pays. The various…

Photosynthesis: nature requires carbon dioxide


Wrong diagnosis, unworkable cures? All is not well in the strange world of climate hysteria, as its promoters flounder in the mire of their own creation. Crippling costs could sink their supposed solutions.
– – –
A team led by researchers at the University of Virginia cautions that when it comes to climate change, the world is making a bet it might not be able to cover, says Phys.org.

The team’s new paper in Nature Climate Change explores how plans to avoid the worst outcomes of a warming planet could bring their own side effects.

The handful of models the United Nations Intergovernmental Panel on Climate Change and decisions makers around the world trust to develop strategies to meet carbon neutrality commitments all assume negative emissions technologies will be available as part of the solution.

Using computer models to make climate predictions? All we can say is: good luck with that.
– – –
Providing annually-updated five-year climate predictions at global and continental scales is the focus of a new international science collaboration co-ordinated by the WMO and led by the UK’s Met Office.

For the first time, climate scientists have joined forces and resources to produce an annually-updated climate snapshot looking at the next five years.

Harnessing the best computer models from ten climate centres around the world, every year will produce a new climate prediction looking out to five years ahead.

The EU is no stranger to audit problems and accounting stories, let’s say, and this one maintains the tradition. Pretending to ‘tackle climate change’ can be expensive of course.

Brussels has been dragged into a bogus accounting scandal after it was claimed climate change spending had been overblown by at least €24 billion, reports the Daily Express.

The European Court of Auditors has questioned the European Commission’s claims about its climate-change programmes.

It was found the European Union’s powerful executive had substantially overestimated the amount it spent on preventing global warming through the use of clever-accounting.

Instead of promoting meaningless climate thresholds, targets etc., alarmists might want to take a closer look at the neglected topic of natural factors.
– – –
A new study demonstrates how a prolonged warming pause or even global cooling may happen in coming years despite increasing levels of atmospheric greenhouse gases — caused by natural climatic variability, says The GWPF.

Natural climatic variability has always been a topic that contains a lot of unknowns, but it has been rarely explicitly stated just how little we know about it.

Such variability has been habitually underplayed as it was “obvious” that the major driver of global temperature was the accumulation of greenhouse gasses in the atmosphere, with natural variability a weaker effect.

But the global temperature data of this century demonstrate that natural variability has dominated in the form of El Ninos.

Climate models are too unreliable to be any serious guide to the future, as the author points out. But getting decision makers to understand that is near-impossible in many countries, hence the acceptance of alarmist nonsense.

Shock, horror: According to the WMO and the Met Office, there is a 3% chance of the forthcoming five-year global temperature average exceeding 1.5°C, says Dr. David Whitehouse @ The GWPF.

There are several definitions of hustle. One of them is to use forceful actions to promote an action or point of view.

It’s everywhere of course and in all aspects of climate change. It’s all too apparent when scientists want grants, jobs and headlines.

It’s no new discovery that combining hustle with statistics can get you anywhere.

The recently released news from the World Meteorological Organisation (WMO), prepared by the UK Met Office, that there is a “growing chance” of the world exceeding the “Paris threshold” of 1.5°C in global temperature above pre-industrial levels is a prime example of this.

Unfortunately ‘the science’ of the climate is at most a sideshow in political circles.

PA Pundits - International

By Dr. Jay Lehr and Tom Harris~

It should be no surprise to our readers that climate change was never a scientific issue, though politicians and well—financed scientists promoted it as such. It has always been a political movement aimed at increasing the size of government and installing a Socialist system. Such a system would eliminate individual freedom while enhancing the control of the elites to achieve their ultimate goal: power over the people.

It was a very transparent plan: convince the public that life—giving carbon dioxide is a danger to humanity and that, were the Earth to be a few degrees warmer, disaster would necessarily follow. You buy this dystopian fantasy and you give your government control of the very breathe you exhale, the number of children you are allowed and every kilowatt of energy your life may consume. As fantastically absurd as this fiction is, those who…

In climate fantasy world, everything is near-constant except human-caused trace gas emissions. Pathetic that this is considered to be serious science, rather than juvenile nonsense.
– – –

Humans may need to “wait for decades” to see the results of large emission cuts on global surface temperatures, scientists have said.

Researchers in Norway used computer simulations to analyse various scenarios that looked at the effects of rapid reductions in several types of greenhouse gas emissions, such as carbon dioxide (CO2), methane and black carbon, says TalkTalk.

They found that although large-scale emission cuts are needed to achieve the global climate goals, it may take decades before the effects of the reductions on temperatures can be measured.

Are climate models getting any better, or even getting worse? Their ‘projections’ almost invariably expect more warming than is observed, often a lot more. Now the uncertainty is increasing.
– – –
As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is likely related to challenges simulating the formation and evolution of clouds, says ScienceDaily.

The new research, published in Science Advances, gives an overview of 39 updated models that are part of a major international climate endeavor, the sixth phase of the Coupled Model Intercomparison Project (CMIP6). The models will also be analyzed for the upcoming sixth assessment report of the Intergovernmental Panel on Climate Change (IPCC).

Compared with older models, a subset of these updated models has shown a higher sensitivity to carbon dioxide — that is, more warming for a given concentration of the greenhouse gas — though a few showed lower sensitivity as well.

The end result is a greater range of model responses than any preceding generation of models, dating back to the early 1990s.

Or relying on any climate modelling, some might say given its current tendency toward overheated predictive mediocrity.
– – –
The purpose of global climate policy is to get us from the dangerous upper end of the forecast range down to the safe bottom end. In fact, we are already there.

Whenever you read a media story about how we’re heading toward catastrophe if we continue operating “business as usual” — i.e., if we don’t slash carbon emissions — the reports are almost always referring to a model simulation using RCP8.5.

And you can bet that nowhere in the story will they explain that RCP8.5 is an implausible worst-case scenario that was never meant to represent a likely base case outcome, or that scientists have begun castigating its usage as a prediction of a doomed business-as-usual future.

How does this make any sense?

A vast tarpaulin unravels, gathering speed as it bounces down the glacier over glinting snow.

Summer is here and the alpine ice is being protected from global warming, reports Phys.org.

In northern Italy, the Presena glacier has lost more than one third of its volume since 1993.

Once the ski season is over and cable cars are berthed, conservationists race to try and stop it melting by using white tarps that block the sun’s rays.

So when global temperatures failed to behave as models expected due to inevitable but hard to predict natural variation, they were forced to re-think – or just think? The GWPF concludes, at the risk of stating the obvious: ‘The lesson of the hiatus is that we do not understand internal climatic variability as much as many think we do, and our predictive power is less than many believe.’
– – –
Researchers from the Universities of Princeton, California, Tokyo, Kyushu and the Scripps Institution of Oceanography, say the recent hiatus in global temperature increase has led to a surge in climate science.

The global effort to understand the global warming hiatus they say has led to increased understanding of some of the key metrics of global climate change such as global temperature and ice-cover.

Searching for an answer to the hiatus, they say, meant that the scientific community grappled with difficulties with these climate metrics, in particular the fact that they do not unequivocally portray the same story about global warming.

In this blog post by the Met Office, everyday weather forecasting barely gets a look-in. Now it’s about ‘inevitable climate changes’ and so on. The whole thing reeks of propaganda, and we can expect another 30 years of it.

In Part I of this two-part blog series (published yesterday) Professor Albert Klein Tank described the history and highlights of the Met Office Hadley Centre over the past 30 years, says the UK Met Office.

Here the Director of the Met Office Hadley Centre focuses on the future.

The next 30 years

In the next 30 years, the role of climate science at the Met Office Hadley Centre will evolve to one of quantifying the predicted changes in climate, and providing more detailed information on what these changes mean to individuals.

How can we help societies plan for the future and manage the risks from extreme climate events and avoid impacts which are too drastic to cope with?

Svante Arrhenius


The eternal question – was the Arrhenius climate theory erroneous? Still looking for convincing evidence of it, the author concludes.
– – –
But he did change his mind …

This 1912 newspaper article (here) shows that a century ago the worthy citizens of Warkworth were followers of Svante Arrhenius’s new theory that global warming would be caused by mankind’s emissions of greenhouse gases, says Richard Treadgold @ Climate Conversation (NZ).

Forty years earlier Tyndall had identified CO2 as a greenhouse gas.

Arrhenius followed up with newly available data in 1896 and calculated that doubling CO2 would increase temperatures by 5°C or 6°C. In 1906 he reduced it to 4.0°C.
