Photosynthesis: nature requires carbon dioxide


This seems open to interpretation. Does it lead to the possibility that most CO2 rise is natural, and therefore all attempted reductions are an even bigger waste of time, money and resources than they were anyway? Here the BBC serves up another dollop of warmist assertions it can’t or won’t try to justify, presumably in an attempt to prevent any inconvenient notions about greenhouse gas theory from entering its audience’s heads.

The global response to the Covid-19 crisis has had little impact on the continued rise in atmospheric concentrations of CO2, says the World Meteorological Organization (WMO).

This year carbon [dioxide] emissions have fallen dramatically due to lockdowns that have cut transport and industry severely, says BBC News.

But this has only marginally slowed the overall rise in concentrations, the scientists say.

Of course the assumption behind most of this is that the climate needs ‘saving’ from the demonic trace gas CO2, according to failing climate models anyway. We’ll skip most of the BBC commentary and show the main points of the plan. The expressed aim is ‘to put the UK on track to meet its goal of net zero emissions by 2050’. No sign of the eye-watering costs, in this report at least.

New cars and vans powered wholly by petrol and diesel will not be sold in the UK from 2030, Boris Johnson has said.

But some hybrids would still be allowed, he confirmed.

It is part of what the prime minister calls a “green industrial revolution” to tackle climate change and create jobs in industries such as nuclear.

Green dreamland


Futile obsession with the trace gas carbon dioxide looks likely to expose the UK government’s so-called climate policies as hopelessly unrealistic, soon enough. Net zero or not zero?
– – –
The UK is on course to reduce its emissions by less than a fifth of what’s needed to meet interim climate change targets, according to data shared exclusively with Sky News.

The think tank Green Alliance says its analysis of current policies shows the longer-term goal of being net zero by 2050 is also in jeopardy.

The government is shortly expected to announce a ten point plan of action on climate change. But Green Alliance says even proposed policies including bringing forward the banning of sales of new petrol, diesel and hybrid cars wouldn’t be enough to get the government to even half of its interim reduction target.

Sales of petrol, diesel and hybrid cars are currently due to end in 2040 though the government is considering bringing that forward to 2035 and green groups want them withdrawn by 2030.

Not the latest model


They may imagine this will have some sort of effect on the global climate in the long run, but even if it does it will be too small to be worth mentioning. But so-called green ideology must prevail, in the minds of most of today’s political leaders.

British Prime Minister Boris Johnson plans to announce next week a ban on the sale of new petrol and diesel cars from 2030, five years earlier than previously planned, the Financial Times reported on Saturday.

Britain had originally planned to ban the sale of new petrol and diesel-powered cars from 2040, as part of efforts to reduce greenhouse gas emissions, and in February Johnson brought this forward to 2035, reports Car and Bike.

Citing unidentified industry and government figures, the FT said Johnson now intended to move the date forward again to 2030 in a speech on environmental policy he is expected to give next week.

Design concept


Another attempt to play the imaginary ‘human-caused climate’ game gets underway. This time it’s ammonia (NH3), a compound of nitrogen and hydrogen, used as fuel to appease the legions of carbophobes in power today.

An enormous engine, the height of three floors, growls loudly at a test centre in Copenhagen.

Nearby a team of engineers supervise it from a control room resembling a ship’s bridge.

Usually such an engine would be propelling a large ship across the sea, but this one is being prepared to take part in a ground-breaking project, says BBC News.

Engineers want to see if they can make it run on liquid ammonia.

How will they react if or when it turns out that ECS only exists in their imaginations anyway?

Climate science is dominated by alarmists addicted to the idea that increasing carbon dioxide will cause dangerous global warming. How much warming is thus the central scientific question.

This question has been surprisingly difficult to answer despite 40 years of research, costing tens of billions of dollars. Now the issue is exploding because two different answers are emerging, one harmlessly low and the other dangerously high. This divergence is a crisis for the alarmist community. How they handle it remains to be seen.

What follows is a slightly technical explanation of the situation.

The issue centers on a benchmark estimate of the impact of increasing CO2 on global temperature. This is called the “equilibrium climate sensitivity” or ECS. The basic question is what will the global average temperature be when the CO2 level is double the supposedly original level of 280 ppm? That is, what…

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.

Angstrom showed in a repeatable experiment, described in his peer-reviewed paper in 1900, that the absorption bands of CO2 in the atmosphere were already saturated, therefore further increases would have no additional effect.

“Eco-anxiety” is now a popular term. It is being increasingly used in the media to describe an anxiety condition resulting from the fears about the coming environmental destruction.

Climate Xchange for example, defines Eco-anxiety as a “feeling of stress, grief, helplessness, and fear of uncertainty associated with the grim outlook for our climatic and ecological systems if business continues as usual.” The American Psychological Association defines Eco-anxiety as “a chronic fear of environmental doom.”

In essence, it is a psychological condition wherein people are anxious about earth’s future and the changes in climate due to burning of fossil fuels. The mainstream media has been harping around the idea of eco-anxiety for quite sometime now. Interestingly, it has been associated more with the climate fears of the school-going generation.

The coverage of the student climate strike movement and dramatic speeches by celebrity child activists like Greta…

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…

Coal-hungry China [image credit: democraticunderground.com]


Doesn’t sound very likely, somehow. How much are 40-year policy announcements worth anyway? The report speaks of ‘the lack of scalable low-carbon alternatives’, and requires sales of EVs well over 300 million to help meet the so-called carbon neutrality target.
– – –
China requires over $5 trillion of investments to reach its pathway for carbon-neutrality by 2060, according to a new study released by Wood Mackenzie, reports PEI.

China needs to expand its solar, wind and storage capacities by 11 times to 5,040GW by 2050 compared to 2020 levels, to be able to meet its 2060 goal.

Coal-fired power capacity will need to be halved while gas ends at the same level as in 2019. Total power output will need to expand by nearly 2.5 times to 18,835TWh by 2050 compared to current levels.

One challenge restricting China to reach its carbon-neutral goal is the lack of scalable low-carbon alternatives in the transport and industrial sectors.

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.

The government minister is talking up ‘the UK’s hydrogen ambitions’ here. Another potentially massive drain on the increasingly threadbare electricity grid system beckons. How much more pseudo-green pie can these deluded carbophobes lob into the sky?
– – –
Supported by a £750,000 grant from the Department for Transport (DfT), the trial of the HydroFLEX train took place in Warwickshire, reports New Civil Engineer.

It follows almost two years’ development work and more than £1M of investment by both Porterbrook and the University of Birmingham. Unlike diesel trains, hydrogen-powered trains do not emit harmful gases, instead using hydrogen and oxygen to produce electricity, water and heat.

Irrational fear of a minor trace gas in the atmosphere, largely based on the output of failing climate models, continues to disrupt national energy policies. EU leaders add to the chaos and confusion.

The European Commission turned down Dutch plans to support hydrogen production with subsidies, reports the NL Times.

The government of the Netherlands wants to use hydrogen instead of other fossil fuels to reduce greenhouse gas emissions, but because the Dutch plans got shot down, this will not be continued, Climate Minister Eric Wiebes told the Tweede Kamer, the lower house of Parliament, on Monday, according to FD.

The government saw possibilities to replace oil, natural gas and coal by hydrogen, especially within heavy industry.

A no-deal Brexit could cost up to 5,000 jobs in Ireland’s fisheries, but it’s not just access to the UK’s coastal waters that the country is hoping to hold on to in any post-Brexit arrangement, says The Conversation @ Phys.org.

Perhaps more important to Ireland is the UK’s motorway network.

Every year, more than 150,000 trucks transport over 3 million tons of freight to and from Ireland to the rest of the single market across the UK land bridge.

One route involves goods being shipped from Dublin to Holyhead by ferry and then by road to Dover before being shipped to Calais.

It’s difficult to overestimate the importance of this land bridge for Ireland.

Earth and climate – an ongoing controversy


Facebook, accountable only to its investors, now intends to pose as a proxy authority on the world’s present and future climate. But the author of the article below wants Facebook to go further and impose its own views on people, while hiding behind the usual catch-all accusation of ‘climate change denialism’ but offering no definition of it. Presumably suggesting that a carbon dioxide level of 0.04% in the atmosphere might not be a massive climate problem is beyond the pale, and should be suppressed? Without clarity about what is out of bounds in discussion, the risk of unfair censorship is obvious.
– – –
Even as Facebook, the world’s largest social media platform, admits that climate change “is real” and that “the science is unambiguous and the need to act grows more urgent by the day” the platform appears unwilling to take steps to really stand up to the climate change denialism that circulates on its platform, says Techcrunch

The company is set to achieve net zero carbon emissions and be supported fully by renewable energy in its own operations this year.

But as the corporate world slaps a fresh coat of green paint on its business practices, Facebook is looking to get out in front with the launch of a Climate Science Information Center to “connect people with science-based information.”

The company is announcing a new information center, designed after its COVID-19 pandemic response. The center is designed to connect people to factual and up-to-date climate information, according to the company.

The ocean carbon cycle [credit: IAEA]


Shockingly – for some – nature’s ocean carbon cycle is functioning quite well, despite constant attempts by feckless humans to undermine it [/sarc]. Time to revisit those troublesome computer models yet again.
– – –
The world’s oceans soak up more carbon than most scientific models suggest, according to new research, reports Phys.org.

Previous estimates of the movement of carbon (known as “flux”) between the atmosphere and oceans have not accounted for temperature differences at the water’s surface and a few metres below.

The new study, led by the University of Exeter, includes this—and finds significantly higher net flux of carbon into the oceans.

It calculates CO2 fluxes from 1992 to 2018, finding up to twice as much net flux in certain times and locations, compared to uncorrected models.

It should make interesting reading if they include realistic costings. That may be over-optimistic though, as is the idea that they have anything useful to say about why they think all the upheaval is needed at all. As for COP26, flying 30,000 climate alarmists to Glasgow to complain about ’emissions’ says it all about their blatant hypocrisy.

The Committee on Climate Change has revealed plans to publish a blueprint for achieving net-zero ahead of the landmark COP26 climate summit next year, reports EnergyVoice.

Dozens of delegates from the clean energy sector met virtually for the first day of Scottish Renewables Annual Conference 2020 earlier to discuss what needs to happen in order to meet climate targets post-Covid-19.

Among them was Chris Stark, chief executive of the Committee on Climate Change, who confirmed the public body would be releasing a plan to axe carbon emissions in the coming years.

The report will be released around a year before the landmark COP26 climate conference in Glasgow.

Carbophobes discover biomass burning is far from ‘carbon neutral’. It’s taken some of them a long time to admit that it’s one of their clumsiest attempts to ‘tackle’ the phantom that is human-caused climate change.
– – –
Europe’s academies of science have called on EU lawmakers to introduce a “radically new standard” in the blocs’ Emissions Trading Scheme (ETS) to ensure net carbon emissions from biomass power stations are “properly accounted for and declared”, reports Euractiv.

The ETS is the EU’s flagship tool for cutting greenhouse gas emissions, and obliges power generators, industrial emitters as well as airlines to buy CO2 permits on the market to cover some of the pollution they emit.

But although the ETS currently assumes that all biomass is carbon neutral, Europe’s academies of science say this is mostly not the case.

But they ignore the fact that historical changes in carbon dioxide levels always followed changes in temperatures, so could not be the cause of such changes. The article below asserts the opposite, and talks about ‘better understanding’ while promoting a greenhouse climate theory that says one minor trace gas is all that matters.
– – –
A University of Arizona-led team has nailed down the temperature of the last ice age—the Last Glacial Maximum of 20,000 years ago—to about 46 degrees Fahrenheit (7.8 C), says Phys.org.

Their findings allow climate scientists to better understand the relationship between today’s rising levels of atmospheric carbon dioxide—a major greenhouse gas—and average global temperature.

The Last Glacial Maximum, or LGM, was a frigid period when huge glaciers covered about half of North America, Europe and South America and many parts of Asia, while flora and fauna that were adapted to the cold thrived.

“We have a lot of data about this time period because it has been studied for so long,” said Jessica Tierney, associate professor in the UArizona Department of Geosciences. “But one question science has long wanted answers to is simple: How cold was the ice age?”

Electrification of 7,500 km of the UK’s major road network would enable most lorries to be powered by overhead charging cables, resulting in dramatically reduced carbon emissions, a new report has found.

A team from the Centre for Sustainable Road Freight (SRF) – bringing together heavy vehicle engineering expertise from the Department of Engineering and logistics expertise from Heriot-Watt University and the University of Westminster and a consortium of industry partners—has proposed that building a so-called ‘electric road system’ could be used to decarbonise 65% of UK lorry kilometers traveled by 2040, says TechXplore.
