The ocean carbon cycle [credit: IAEA]


The Woods Hole researchers find ‘the efficiency of the ocean’s “biological carbon pump” has been drastically underestimated’, with inevitable implications for climate modelling and assessments. Given that the oceans hold 50 times more CO2 than the atmosphere, this must matter.

Every spring in the Northern Hemisphere, the ocean surface erupts in a massive bloom of phytoplankton, says Phys.org.

Like plants, these single-celled floating organisms use photosynthesis to turn light into energy, consuming carbon dioxide and releasing oxygen in the process.

When phytoplankton die or are eaten by zooplankton, the carbon-rich fragments sinks deeper into the ocean, where it is, in turn, eaten by other creatures or buried in sediments.

This process is key to the “biological carbon pump,” an important part of the global carbon cycle.

Demonising a harmless trace gas can lead to bizarre results. Here’s another one.

Environmentalists and green bureaucrats have watched in shock as the coronavirus global shut down has now caused carbon credit markets to crash.

The European Union’s carbon credits price has fallen by 40% this year so far. This market was worth $215 billion last year, according to Bloomberg Environment. The price drop has rubbed out two years of EU carbon market gains.

It turns out that if there are extremely low levels of carbon dioxide emissions, as is the case currently with businesses and industries shuttered, the companies doing the carbon emitting don’t have to buy any carbon credits to make up for it.

And if no one is buying carbon credits to offset emissions, well, then the so-called “market” for carbon dies.

Wait a minute, isn’t the whole idea of these carbon credits to reduce CO₂ emissions; what climate campaigners refer to as…

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.

Variation in solar activity during a recent sunspot cycle [credit: Wikipedia]


This seems worth another airing in the face of today’s insistent, but evidence-light, claims from climate obsessives that the world’s present and future weather is going to be largely determined by human activities.

If the energy from the sun varies by only 0.1 percent during the 11-year solar cycle, could such a small variation drive major changes in weather patterns on Earth? – asks Universe Today.

Yes, say researchers from the National Center for Atmospheric Research (NCAR) who used more than a century of weather observations and three powerful computer models in their study.

They found subtle connections between solar cycle, the stratosphere, and the tropical Pacific Ocean that work in sync to generate periodic weather patterns that affect much of the globe.

Scientists say this will help in predicting the intensity of certain climate phenomena, such as the Indian monsoon and tropical Pacific rainfall, years in advance.

Making electricity unreliable and expensive when it used not be — sounds idiotic, but seems to be the norm with climate-obsessed governments these days.

I recently got an intriguing email from Professor Guus Berkhout, president of the Climate Intelligence Foundation or CLINTEL. It contained this striking paragraph and the last sentence really got me thinking:

“The past 150 years show that affordable and reliable energy is the key to prosperity. The past 150 years also show that more CO2 is beneficial for nature, greening the Earth and increasing the yields of crops. Why do governments ignore these hard facts? Why do they do the opposite and lower the quality of life by forcing high-cost, dubious low-carbon energy technologies upon their citizens? The zero-emission act is a crime against humanity.” (Emphasis added.)

So I looked into the law on crimes against humanity and Professor Berkhout may have a strong case. At its simplest, a crime against humanity is a government policy that systematically and knowingly harms a specific group…

Of course the other question about the start of an ice age still remains.

New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth’s axis was approaching higher values, reports Phys.org.

During these times, longer and stronger summers melted the large Northern Hemisphere ice sheets, propelling the Earth’s climate into a warm ‘interglacial’ state, like the one we’ve experienced over the last 11,000 years.

The study by Ph.D. candidate, Petra Bajo, and colleagues also showed that summer energy levels at the time these ‘ice-age terminations’ were triggered controlled how long it took for the ice sheets to collapse, with higher energy levels producing fast collapse.

Researchers are still trying to understand how often these periods happen and how soon we can expect another one.

Earth turned faster at the end of the time of the dinosaurs than it does today, reports Phys.org, rotating 372 times a year compared to the current 365, according to a new study of fossil mollusk shells from the late Cretaceous.

This means a day lasted only 23 and a half hours, according to the new study in AGU’s journal Paleoceanography and Paleoclimatology.

The ancient mollusk, from an extinct and wildly diverse group known as rudist clams, grew fast, laying down daily growth rings. The new study used lasers to sample minute slices of shell and count the growth rings more accurately than human researchers with microscopes.

So-called ‘net zero emissions’ of carbon dioxide is a smoke and mirrors political game that has little or nothing to do with any actual climate.

PA Pundits - International

By David Wojick, Ph.D. ~

The UK has passed a law mandating zero net emissions of CO2 and other greenhouse gases by 2050. Airplanes emit a lot of CO2 and cannot run on batteries, or not very far anyway, so what does net zero air travel look like?

We now have two studies on this question, which are diametrically opposed. They illustrate very nicely the fact that climate alarmism has split into two opposing camps — the moderates and the radicals. Let us ignore the fact that both camps are wrong and look at the difference between these two studies. They say a lot about policy debates to come.

The first study is by the airline industry itself, with the apparent blessing of the UK government. This is the moderate view and it is very moderate indeed. In fact it is almost benign.

They are up against it. Governments are now finding themselves increasingly boxed in by their own climate ideology. From the report below:
Richard Tol, professor of the economics of climate change at the Vrije Universiteit Amsterdam, said it is “highly unlikely” that the Netherlands will rise to the challenge, saying a [extra] 10% emissions reduction by the end of 2020 would “require shutting down a substantial part of the economy”.

But what options are there? Nuclear power is unpopular and can’t be built quickly anyway, while wind and solar power are part-time, intermittent, and relatively expensive. No viable ‘off-the-shelf’ way exists to store electricity on a massive scale. Awkward.

The Netherlands is under pressure to slash emissions in sectors such as power generation and agriculture in 2020 after a ruling by a top court made the government a reluctant ‘test case’ for tougher global climate policies, says Climate Home News.

The government of conservative Prime Minister Mark Rutte is working out new measures after the Dutch Supreme Court in December ordered it to cut greenhouse gas emissions by 25% by the end of 2020, compared with 1990 levels, as its fair share to combat climate change.

So termites could lead us to the solution to…
CO2-generating termites? The wizardry of would-be planet savers – or could it be the sharpness of opportunists? – never ceases to amaze.

Hidden metal deposits needed to transition the world to low emission technologies can be discovered using metallic blue crusts in soils and on termite mounds as signposts, according to new research from Australia’s national science agency, CSIRO.

CSIRO’s study in the southern Pilbara region of WA used new advances in sample analysis to show how metallic blue crusts, known as manganese crusts, display unique zinc signatures that indicate the presence of other base metals in the surrounding area, reports Technology.org.

No great surprise there. As usual the idea is to demonize the essential trace gas carbon dioxide, paving the way to useless ‘solutions’ to an imaginary problem. Note: Attenborough is *not* a climate expert, and admits so himself.

The first two meetings of Climate Assembly UK, dubbed a ‘citizens’ assembly’ on climate change, have taken place in Birmingham over the course of a couple of weekends in January and February, writes Ben Pile (via Climate Change Dispatch).

The climate assembly has brought together 110 randomly selected members of the public to discuss a range of climate issues and policies with a range of experts, including David Attenborough.

The task of the assembly, which will meet over two more weekends this spring, is to decide on a set of recommendations for how the government can best meet its pledge to achieve Net Zero carbon emissions by 2050.

So much for the “hotter drier” Australian future they were warning us about 3 weeks ago.

As predicted, droughts in Australia often end in floods. It is the way it has always been. Today people are already being rescued from the rising water and possibly another 200 -300mm of rain may fall before Sunday warns the BOM. Many fires have been extinguished.

Climate change has made no difference to the drought trends in Australia in the last 178 years and climate models are totally skilless at rainfall. When will the climate modelers admit that these are natural cycles?

‘We’re only half way through’: East coast smashed by flashflooding and heavy winds

Forecasters become increasingly concerned that even more rain could fall even faster than expected as five people have been rescued from floods.

Intermittency, meaning unreliability, is of course guaranteed with wind and solar power. The problem being that some governments now proceed as though that doesn’t matter any more, preferring to trumpet absurd claims about ‘saving the climate’. If they persist, eventual power shortages look inevitable.

Germany now generates over 35% of its yearly electricity consumption from wind and solar sources, says the Asia Times.

Over 30,000 wind turbines have been built, with a total installed capacity of nearly 60 GW.

Germany now has approximately 1.7 million solar power (photovoltaic) installations, with an installed capacity of 46 GW. This looks very impressive.

Unfortunately, most of the time the actual amount of electricity produced is only a fraction of the installed capacity. Worse, on “bad days” it can fall to nearly zero.

Significant changes since 2007 or so are observed but not explained, which seems to leave them open to interpretation. To get that ball rolling the recent solar slowdown could be mentioned.
A 2015 NASA study said that ‘an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.’

Using the latest satellite technology from the European Space Agency (ESA), scientists from the University of Bristol have been tracking patterns of mass loss from Pine Island — Antarctica’s largest glacier, reports SciTechDaily.

They found that the pattern of thinning is evolving in complex ways both in space and time with thinning rates now highest along the slow-flow margins of the glacier, while rates in the fast-flowing central trunk have decreased by about a factor of five since 2007.

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…

Theories abound, but the inevitable carbon dioxide one pops up at the end.

Scientists have identified the world’s oldest asteroid crater in Australia, adding it may explain how the planet was lifted from an ice age, reports BBC News.

The asteroid hit Yarrabubba in Western Australia about 2.2 billion years ago – making the crater about half the age of Earth, researchers say.

Their conclusion was reached by testing minerals found in rocks at the site.

The scientists say the find is exciting because it could account for a warming event during that era.

So what’s new? Nothing really, but these issues show few if any signs of being resolved in the near future. Governments intending to pressure or force people to buy EVs are going to be unpopular with millions of car users, it would seem. Woolly climate propaganda isn’t impressing many buyers.

Ipsos, the global research and insights organization, says it has uncovered the thoughts of consumers regarding BEVs, Green Car Congress reports.

These new findings are released in the second module of the Ipsos Global Mobility Navigator Syndicated Study, in which 20,000 consumers worldwide shared their opinions on alternative engines and what it would take to get them to consider one.

Low tide in Venice


This so-called man-made climate change thing must be a versatile beast, if it exists outside of myths. Wednesday’s rare super blue blood moon gets some of the blame here, but recent low rainfall also played a part.

Although the water levels in the city’s famous canals rise and fall with the tide, exceptionally low tides have left canals bare, reports Sky News.

Two months ago the high tide in Venice peaked at 187cm (6.14ft), leaving around 70% of the lagoon city centre under salt water.
