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.

Some more inconvenient data and discussion from an experienced and well-known meteorologist. Planting more trees may as he proposes be useful, but so might chopping down fewer of them for biomass burning and wind turbine land clearances.

I believe that as the COVID-19 situation diminishes, a major pivot to man made climate change as the major driver of impending doom will come front and center, says Joe Bastardi.

Perhaps I will be wrong, but the naming of AOC by Joe Biden as an advisor on how to fight climate change, to me, was the first signal this is going to happen.

This is an insensitive tactic, since the misery of Covid-19 is real, immediate, and loaded with great uncertainty. Future generations can opine on the result of the measures taken to combat it. Yet, as I wrote back in March:

Covid-19 and climate false equivalencies

Climate change accused of being deadlier than Covid 19 — Fact check

and the foundation for this was being set for the turn we are seeing now.

They might do well to remember that historic climate data always show carbon dioxide rises *following* temperature rises, often with quite a long time lag, never leading them, which raises awkward questions for ‘heat-trapping’ theories and climate models based on them.
– – –
A new study from University of Michigan climate researchers concludes that some of the latest-generation climate models may be overly sensitive to carbon dioxide increases and therefore project future warming that is unrealistically high, says Phys.org.

In a letter scheduled for publication April 30 in the journal Nature Climate Change, the researchers say that projections from one of the leading models, known as CESM2, are not supported by geological evidence from a previous warming period roughly 50 million years ago.

The researchers used the CESM2 model to simulate temperatures during the Early Eocene, a time when rainforests thrived in the tropics of the New World, according to fossil evidence.

Kangerlussuaq Fjord, Greenland [image credit: notsogreen.com]


Less than a year ago NASA was reporting from Greenland: Jakobshavn Glacier Grows for Third Straight Year, and ‘The glacier grew 22 to 33 yards (20 to 30 meters) each year between 2016 and 2019.’ So this new report may be, to some degree at least, already obsolete since it says: ‘The largest thinning rates were between 4 and 6 m a−1 in Jakobshavn and Kangerlugssuaq glaciers’.
– – –
Sea levels have risen by 14mm since 2003 due to ice melting in Antarctica and Greenland, scientists have said.

Nasa launched a satellite to measure global heights in 2018 and spotted the rise after bouncing laser pulses against sheets of ice, says the London Evening Standard.

The study found that Greenland lost an average of 200 billion tonnes of ice per year, and Antarctica lost an average of 118 billion tonnes.

One billion tonnes of ice is enough to fill 400,000 Olympic-sized swimming pools.

A team led by researchers at the University of Washington compared the data with measurements taken by the satellite between 2003 and 2009.

The findings, published in the journal Science, found the loss of ice from Antarctica and Greenland outweighs any gains from accumulated snow.

Earth and climate – an ongoing controversy


H/T The GWPF

The article would have us believe that so-called ‘greenhouse’ gases are warming while aerosols are cooling, the balance of the two is unknown and that needs addressing to improve climate predictions. There may be other ways to get better predictions, but that’s another matter.

Pollution declines from pandemic shutdowns may aid in answering long-standing questions about how aerosols influence climate, says Scientific American.

As the world scrambles to contain the spread of COVID-19, many economic activities have ground to a halt, leading to marked reductions in air pollution.

And with the skies clearing, researchers are getting an unprecedented chance to help answer one of climate science’s thorniest open questions: the impact of atmospheric aerosols.

Research continues, but what other ‘futuristic’ climate-related plans might they want to conjure up if this trial is deemed a success?
– – –
An ambitious “cloud brightening” experiment has been carried out over Australia’s Great Barrier Reef in an early-stage trial that scientists hope could become a futuristic way to protect coral from global warming, says Phys.org.

In an attempt to cool waters around the reef by making clouds reflect more sunlight, researchers said they used a boat-mounted fan similar to a snow cannon to shoot salt crystals into the air.

Results from the trial were “really, really encouraging”, the project’s lead scientist Daniel Harrison from Southern Cross University said on Friday.

The researchers estimate that carbon dioxide levels in the atmosphere were well over 1000 parts per million in those days, compared to 400+ ppm today. Antarctica and Australia were much closer together.

Antarctica was covered in rainforest in the time of the dinosaurs, according to a new study, Metro News reports.

Researchers have found evidence the South Pole had a climate and forests similar to New Zealand today in a startling discovery. The team discovered soil from an ancient rainforest from the Cretaceous period within 900 km of the South Pole.

The analysis carried out by an international team of researchers of roots, pollen and spores shows the world was a lot warmer than previously thought.

Schemes to ramp up climate alarm propaganda with ‘warming’ [sic] labels are already in the pipeline e.g. in Sweden. They try to claim a health risk from the warmer weather they feel sure lies ahead, while pointing the finger at humans for this supposed problem and equating it to tobacco smoking. If the pollution doesn’t get you, the climate emergency will…type of thing. Crude stuff loosely based on dodgy climate models.
– – –
Mike Gill and colleagues explain how the implementation of of fossil fuel labelling could have a significant impact on the awareness of climate change, says The British Medical Journal blog. This article is part of The BMJ’s Health in the Anthropocene collection.

The use of fossil fuels should be rapidly reduced to keep the global mean temperature increase to well below 2°C above pre-industrial levels—a core goal of the Paris Agreement on climate change.

Emphasising the risks to health of fossil fuel use, now and in the future, could motivate action.

CO2 is not pollution


What a drag for climate alarmists. Anyone who thinks we have ‘carbon pollution’ (see below) has a terminology problem, so can’t be much of an expert. They’re now going all-out to pretend carbon dioxide is affecting air quality, an obvious absurdity as vegetation depends on it for growth, aka photosynthesis. Should we believe these ‘experts’ don’t know that?
– – –
Economic shock waves from the coronavirus outbreak have curbed carbon pollution from China and beyond, says Phys.org, but hopes for climate benefits from the slowdown are likely to be dashed quickly, experts say.

As governments prepare to spend their way out of the crisis, including with large infrastructure projects, global warming concerns will be little more than an afterthought, dwarfed by a drive to prop up a stuttering world economy, they say.

Preparations for a make-or-break climate summit in November are already off track, with host Britain focused on its Brexit transition, and the challenge to its health system of the gathering epidemic.

The author argues: “In summary, evidence substantiates that a well-defined, persistent and non-moving ocean warm trend originating off the East Coast of the United States is the result of super-heated and methane enriched fluids emitted from numerous seafloor hydrothermal vents/hot springs. This has far-reaching implications concerning the root cause of current worldwide ocean warming.”

A well-defined ocean warming trend originating off the United States East Coast is likely from super-heated and methane-enriched fluids emitted from numerous seafloor hydrothermal vents/hot springs, says James Kamis at Climate Change Dispatch.

Supporting evidence:

This trend has shown up on shallow Sea Surface (SST) maps since their advent in 1997 and has likely been present for thousands of years.

Climate paranoia has hit the UK courts big-time. It now seems illegal not to obsess over trace gases in the atmosphere, due to the Paris climate agreement.

Heathrow Airport’s controversial plans to build a third runway have been thrown into doubt after a court ruling, reports BBC News.

The government’s Heathrow’s expansion decision was unlawful because it did not take climate commitments into account, the Court of Appeal said.

Heathrow said it would challenge the decision, but the government has not lodged an appeal.

The judges said that in future, a third runway could go ahead, as long as it fits with the UK’s climate policy.

Another fiasco on the way is the EU’s plan to go ‘carbon neutral’ at vast expense, with no obvious post-Brexit source of funding.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Melanie Phillips is one of the few who have been fighting back against global warming dogma since the early days.

Despite being marginalised by the Daily Mail, she is still continuing the fight:

A few commentators have begun to stumble towards the fact that the policy of becoming “carbon neutral” by 2050, as adopted by the UK and the EU, would undo modernity itself.

On Unherd, Peter Franklin observes that, if carried through, the policy will have a far greater effect than Brexit or anything else; it will transform society altogether.

“It will continue to transform the power industry, and much else besides: every mode of transport; how we build, warm and cool our homes; food, agriculture and land use; trade, industry, every part of the economy”.

Franklin is correct. Even so, he seems not to grasp the full implications of the disaster he intuits –…

This contradicts climate alarmist claims such as: Global Warming Is Messing with the Jet Stream. Whether 40 years of data is enough to establish what is ‘normal’, is another matter. The fastest jetstream on record of 231 mph has only just been set, we’re told.
– – –
Rapid Arctic warming has not led to a “wavier” jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

Scientists from the University of Exeter have studied the extent to which Arctic amplification—the faster rate of warming in the Arctic compared to places farther south—has affected the fluctuation of the jet stream’s winding course over the North Hemisphere, reports Phys.org.

Recent studies have suggested the warming Arctic region has led to a “wavier” jet stream—which can lead to extreme weather conditions striking the US and Europe.

However, the new study by Dr. Russell Blackport and Professor James Screen, shows that Arctic warming does not drive a more meandering jet stream.

Instead, they believe any link is more likely to be a result of random fluctuations in the jet stream influencing Arctic temperatures, rather than the other way around.

More wreck-o than eco? Here we find that ‘biodiesel from food crops emits an average of 1.8 times as much CO2 as fossil fuels which increases to three times more in case of biodiesel from palm oil.’ Looks like another non-solution to the claimed problem.

The UK’s aviation industry is touting biofuels as a way to make plane transport greener. But some biofuels can end up doing more harm than good, says Wired.

In the next 30 years, the number of flights is expected to increase by 70 per cent.

Unless things change, by 2050 the aviation industry will have used up more than a quarter of all the carbon dioxide we can safely emit while keeping global warming to under 1.5 degrees Celsius.

But the aviation industry says it has a way out.

A change to about 0.01% of the atmosphere is now claimed to be speeding up the oceans by making winds stronger. Really? They used to claim global warming was weakening the Pacific trade winds:
“The researchers predict another 10 percent decrease by the end of the 21st century. The effect, attributed at least in part to human-induced climate change, could disrupt food chains and reduce the biological productivity of the Pacific Ocean, scientists said.” (2006 report)

A study published today in the journal Science Advances, suggests global ocean circulation has accelerated during the past two decades, reports Phys.org.

The research team found that oceanic kinetic energy shows a statistically significant increase since early 1990s, calculating a 36-percent acceleration of global mean ocean circulation.

The trend is particularly prominent in the global tropical oceans, reaching depths of thousands of meters.

The deep-reaching acceleration of the ocean circulation is mainly induced by a planetary intensification of surface winds, authors said.

Maybe the climate alarmist leaders have finally grown tired of being panned for blatant exaggeration and dishonest fearmongering, based entirely on failing climate models. But of course much of the desired psychological damage has already been done.

Scientists should stop using the very worst predictions for carbon emissions, a study suggests – reporting by the BBC.

Referred to as “business as usual”, the scenario assumes a 500% increase in the use of coal, which is now considered unlikely.

PA Pundits - International

By David Wojick, Ph.D. ~

Ever since she splashed into view I have wondered about Greta Thunberg’s reasoning. Her quoted statements, blasting the world for not doing the impossible, have given no clue where she is coming from.

Now, thanks to some detailed published statements of hers, from the World Economic Forum in Davos, I have my answer. It turns out she is hotly embracing not one, but two, howling fallacies. No wonder she sounds nuts.

To begin with, she cites the IPCC report on climate change from 2018, which claims we have only a few years left to act if theres a 67% chance of keeping the global temperature rise from now to below 0.5 degrees C. (She, like everyone else, talks about a rise of 1.5 degrees, but the IPCC says that 1.0 degrees has already happened, which she knows.) If she said a half a…

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.
