New discovery reveals that ocean algae ‘unexpectedly’ help cool the Earth

A compound found in algae can have a significant role in cloud formation, and is said to be ‘a major source of climate-cooling gases’. A study author suggests a ‘need to rethink’ what the climate impacts are.
– – –
A common type of ocean algae plays a significant role in producing a massively abundant compound that helps cool the Earth’s climate, new research has discovered.

The findings of the study by the University of East Anglia (UEA) and Ocean University of China (OUC) could change our understanding of how these tiny marine organisms impact our planet, says Phys.org.

The work appears in Nature Microbiology.

Climate extremes in Svalbard over the last two millennia are linked to atmospheric blocking, say researchers

Article: ‘Since observational measurements started, blocking in the Arctic has increased, as has Arctic warming.’ When researchers investigated ‘they found a stunning correlation’. No mention of greenhouse gases in the study.
– – –
A team of scientists led by François Lapointe, a research associate at the University of Massachusetts Amherst, has combined paleoclimatic data from the last 2,000 years with powerful computer modeling and in-the-field research on lake sediments and tree rings to show that an understudied phenomenon, known as atmospheric blocking, has long influenced temperature swings in the Arctic.

As temperatures warm due to climate change, claims EurekAlert, atmospheric blocking will help drive ever-wilder weather events. [Talkshop comment – routine alarmist hype].

The study focused on the Norwegian Arctic archipelago, Svalbard, at the edge of the Arctic Ocean, and was published in Nature Communications.

NASA mission flies over Arctic to study sea ice melt causes – calling ‘settled science’ into question?

NASA says: “There are many different factors that influence the sea ice. We’re measuring them to determine which were most important to melting ice this summer.” Where does that leave so-called ‘state-of-the-art’ climate models? They’re only going to be measuring seasonal factors, not longer-term cycles for example, but it’s at least an attempt to look harder at the whole topic.
– – –
It’s not just rising air and water temperatures influencing the decades-long decline of Arctic sea ice, says NASA (via Phys.org).

Clouds, aerosols, even the bumps and dips on the ice itself can play a role.

To explore how these factors interact and impact sea ice melting, NASA is flying two aircraft equipped with scientific instruments over the Arctic Ocean north of Greenland this summer.

Study: Reduced sulphur content in shipping fuel caused ‘nearly 80%’ of recent atmospheric warming

Due to a 2020 shipping regulation…’The net planetary heat uptake has increased by 0.25 Wm−2 since 2020, making the 0.2 Wm−2 due to IMO2020 nearly 80% of the total increase.’ The study also says: ‘The 2023 record warmth is within the ranges of our expected trajectory. The magnitude of IMO2020 induced warming means that the observed strong warming in 2023 will be a new norm in the 2020 s.’ — Two general comments to make here: (1) cloud physics is admitted to be not well understood, and (2) could night-time clear(er) skies mean (more) cooling, in theory at least?
– – –
An 80% reduction in sulphur dioxide shipping emissions observed in early 2020 could be associated with substantial atmospheric warming over some ocean regions, according to a modelling study published in Communications Earth & Environment.

The sudden decline in emissions was a result of the introduction of the International Maritime Organization’s 2020 regulation (IMO 2020), which reduced the maximum sulphur content allowed in shipping fuel from 3.5% to 0.5% to help reduce air pollution, says EurekAlert.

Fuel oil used for large ships has a significantly higher percentage content of sulphur than fuels used in other vehicles. Burning this fuel produces sulphur dioxide, which reacts with water vapour in the atmosphere to produce sulphate aerosols.

These aerosols cool the Earth’s surface in two ways: by directly reflecting sunlight back to space [Talkshop comment – daytime effect only]; and by affecting cloud cover.

Battle of the skies as airlines fight over impact of contrails on the climate

This report summary says ‘Vapour trails conundrum resurfaces’. Cloud formation plays an uncertain part in the debate, for example. An experiment using AI found that real time route selection could play a part in reducing the supposed ’emissions’ problem. Proposed financial penalties for airlines are inevitably resisted, but they’re up against net zero climate obsession.
– – –
Airlines are usually rather good at presenting a united face to the world, particularly when it comes to lobbying global policymakers, says The Telegraph.

But a recent move by the EU to clampdown on so-called contrails, the vapour that spews from an aircraft’s jet engines in a thin cloud-like formation, has set carriers at each other’s throats.

The International Air Transport Association (Iata), which counts most of the world’s flag-carriers among its members, has lobbied Brussels to limit the mandatory monitoring of contrails to only flights within the bloc, in an effort to ease the burden of data collection.

But it has stoked the ire of low-cost operators including EasyJet and Ryanair.

Research quantifies ‘gap’ in CO2 removal – a climate target with no viable plans?

Having been told by the UN-IPCC that nature’s own carbon cycle isn’t up to the job any more, the manufactured problem for climate-obsessed governments seems to be the lack of any ‘carbon removal’ method that is (a) affordable and (b) effective, in terms of the scale of the supposed need. Such is the strange world of climate policy today.
– – –
New research involving the University of East Anglia (UEA) suggests that countries’ current plans to remove CO2 from the atmosphere will not be enough to comply with the 1.5ºC warming limit set out under the Paris Agreement, says Phys.org.

Since 2010, the United Nations environmental organization UNEP has taken an annual measurement of the emissions gap—the difference between countries’ climate protection pledges and what is necessary to limit global heating to 1.5ºC, or at least below 2ºC [Talkshop comment – according to unproven IPCC climate theories].

The UNEP Emissions Gap Reports are clear: climate policy needs more ambition. This new study now explicitly applies this analytical concept to carbon dioxide removal (CDR)—the removal of the most important greenhouse gas, CO2, from the atmosphere.

Britain must spend £30bn to strip CO2 from atmosphere and hit net zero, experts warn

This ‘essential’ expense would likely go the way of HS2 and double or triple in real cost, with at least some costs continuing well after the target date. Absurd is too weak a word to describe this fear of a harmless trace gas essential to nature. CO2 is not pollution.
– – –
Britain must invest [sic] £30bn in a network of massive air cleansing systems designed to strip CO2 from the atmosphere if it is to reach net zero, a government-funded report has warned.

The “direct air carbon capture systems” would remove up to 48 million tonnes of CO2 from the air each year and then pump it into disused oil and gas reservoirs under the North Sea or Irish Sea, says The Telegraph.

Without such a scheme the UK will never reach its target of net zero emissions by 2050, according to the report by Energy Systems Catapult, a government-funded body that promotes innovation.

Why is methane seeping on Mars? NASA scientists have new ideas

Only at night though, it seems. “It’s a story with a lot of plot twists”, said a Mars project scientist. Saturn’s moon Titan is awash with methane, but no sign of life present or past, so why should Mars having some be a surprise?
– – –
The most surprising revelation from NASA’s Curiosity Mars Rover—that methane is seeping from the surface of Gale Crater—has scientists scratching their heads, says Phys.org.

Living creatures produce most of the methane on Earth [Talkshop comment – really?]. But scientists haven’t found convincing signs of current or ancient life on Mars, and thus didn’t expect to find methane there.

Yet, the portable chemistry lab aboard Curiosity, known as SAM, or Sample Analysis at Mars, has continually sniffed out traces of the gas near the surface of Gale Crater, the only place on the surface of Mars where methane has been detected thus far.

Net zero CO2 emissions: A damaging and totally unnecessary goal – Roy Spencer explains why

We may not believe CO2 plays a big part in global atmospherics anyway, but even if it somehow does, the full story is not being told according to this information. Quote: ‘Even though the CO2 emissions continue, atmospheric CO2 levels start to fall around 2060.’
– – –
The goal of reaching “net zero” global anthropogenic emissions of carbon dioxide sounds overwhelmingly difficult.

But that’s not true, because nature doesn’t work that way, says Dr.Roy Spencer (via Climate Change Dispatch).

While humanity continues producing CO2 at increasing rates (with a temporary pause during COVID), how can we ever reach the point where these emissions start to fall, let alone reach zero by 2050 or 2060?

What isn’t being discussed (as far as I can tell) is the fact that atmospheric CO2 levels (which we will assume for the sake of discussion causes global warming) will start to fall even while humanity is producing lots of CO2.

Carbon dioxide, methane levels in the atmosphere hit ‘record highs’ last year – but only since 1959!

We’ll ignore any climate-related assertions in this article and try to look at actual information. How much of the variation of the trace gases mentioned would have occurred anyway, regardless of human activities? As the article says: ‘Carbon dioxide and methane levels have been higher in the far ancient past’. The world obviously didn’t self-destruct back then, so maybe a bit of context there for these latest ‘records’. It’s also known that warmer oceans absorb less carbon dioxide from the atmosphere – an entirely natural process.
– – –
The 2.8 parts per million increase in carbon dioxide airborne levels from January 2023 to December, wasn’t as high as the jumps were in 2014 and 2015, but they were larger than every other year since 1959, when precise records started, says PBS Online.

Carbon dioxide’s average level for 2023 was 419.3 parts per million, up 50% from pre-industrial times.

Last year’s methane’s jump of 11.1 parts per billion was lower than record annual rises from 2020 to 2022. It averaged 1922.6 parts per billion last year.

Need for a rethink of ‘the critical role’ of atmospheric dust in Earth’s climate

It seems ‘classical dust cycle models have over-estimated the amount of dust emission.’ This in turn affects the results from climate models, which ‘have only been providing a fraction of the story’. This ‘has significant implications’ for reconstructions of past climate.
– – –
You may think of dust as an annoyance to be vacuumed and disposed of, but actually, on a grander scale, it is far more important than most people realize, says Phys.org.

Globally, dust plays a critical role in regulating our climate, radiation balance, nutrient cycles, soil formation, air quality and even human health.

But our understanding of it has been hampered by limitations in current mathematical models. These models, built on methods developed decades ago, struggle to accurately simulate the properties and quantities of dust.

The State of the Climate 2023 (GWPF) – evidence of crisis not observed

The summary remarks: ‘There is no visible effect of the global COVID-19 lockdown 2020–2021 in the atmospheric concentration. The increasing amount of atmospheric carbon dioxide is enhancing photosynthesis and thereby global crop yields.’
– – –
London, 28 March — In his annual review of the state of the global climate, Professor Ole Humlum reviews last year’s key data and observations in the context of long-term climate trends, says the GWPF.

The review covers a wide range of temperature measurements in both ocean and atmosphere, alongside reviews of oceanic oscillations, sea level, snow and ice measurements and storms.

Polar vortex is ‘spinning backwards’ above Arctic after major reversal event

The new polar vortex blog hosted by NOAA says ‘some winters come and go without a single interesting thing happening in the stratosphere’, but this one wasn’t one of those. The blog also notes: ‘Odds of polar vortex collapse boosted during El Niño…But not all the El Niños’. The article below says ‘Changes to the polar vortex influence the jet stream, which can in turn impact weather across the Northern Hemisphere’ (caption to NOAA graphic).
– – –
The polar vortex circling the Arctic is swirling in the wrong direction after surprise warming in the upper atmosphere triggered a major reversal event earlier this month, says Live Science.

It is one of the most extreme atmospheric U-turns seen in recent memory.

In the past, disruptions to the polar vortex — a rotating mass of cold air that circles the Arctic — have triggered extremely cold weather and storms across large parts of the U.S.

The current change in the vortex’s direction probably won’t lead to a similar “big freeze.” But the sudden switch-up has caused a record-breaking “ozone spike” above the North Pole.

Can volcanic super eruptions lead to major cooling? Study suggests no

The research came up with ‘relatively modest temperature changes’. One NASA atmospheric scientist commented: “To me, this is another example of why geoengineering via stratospheric aerosol injection is a long, long way from being a viable option.” (Here’s another one). Climate alarmists can imagine doing some things, but so can Hollywood scriptwriters.
– – –
New research suggests that sunlight-blocking particles from an extreme eruption would not cool surface temperatures on Earth as severely as previously estimated, says Phys.org.

Some 74,000 years ago, the Toba volcano in Indonesia exploded with a force 1,000 times more powerful than the 1980 eruption of Mount St. Helens. The mystery is what happened after that—namely, to what degree that extreme explosion might have cooled global temperatures.

When it comes to the most powerful volcanoes, researchers have long speculated how post-eruption global cooling—sometimes called volcanic winter—could potentially pose a threat to humanity.

Weird dent in Earth’s magnetic field is messing with auroras in the Southern Hemisphere

The South Atlantic Anomaly is an interesting phenomenon, which varies over time and may be related to a zone of unusually dense rock.
– – –
A bizarre dent in Earth’s magnetic field above the southern Atlantic Ocean weakens the southern lights, new research finds.

The South Atlantic Anomaly is a large, oval-shaped region over South America and the southern Atlantic Ocean where Earth’s magnetic field is weakest, says Live Science.

The anomaly is already well known for allowing charged particles from the sun to dip close to Earth’s surface, exposing satellites orbiting above to high levels of ionizing radiation, according to NASA.

Why atmospheric geoengineering is dead in the water

Another idea for slaying imaginary climate dragons runs into trouble, as new research finds ‘an intervention that cools the air would not be able to cool the deep ocean on the same timescale’. So for believers in a climate crisis the desired short-term effectiveness just isn’t there.
– – –
Climate change is heating the oceans, altering currents and circulation patterns responsible for regulating climate on a global scale [Talkshop comment – empty assertions]. If temperatures dropped, some of that damage could theoretically [sic] be undone.

But employing “emergency” atmospheric geoengineering later this century in the face of continuous high carbon emissions would not be able to reverse changes to ocean currents, a new study finds.

This would critically curtail the intervention’s potential effectiveness on human-relevant timescales.

Oceans, especially the deep oceans, absorb and lose heat more slowly than the atmosphere, so an intervention that cools the air would not be able to cool the deep ocean on the same timescale, the authors found.

Flying laboratory measuring cloud chemistry above Australia aims to improve climate model predictions

The German scientists are engaged in an ongoing project intended to help refine climate modelling. One sums up their approach: “To predict it, we really need to understand it.” But ideally that understanding, if or when it occurs, should have preceded many of the dire claims already put forward that the global climate is going downhill due to human activities. Such biases could be a hindrance to research.
– – –
A team of German scientists have been circling the skies above northern Australia and the Pacific Ocean in a high-tech research aircraft studying the atmospheric chemistry occurring above the clouds, says ABC News.

The Chemistry of the Atmosphere: Field Experiment (CAFE) team has tracked weather events and taken samples and measurements up to 15 kilometres above sea level.

Professor Mira Pöhlker from the Leibniz Institute for Tropospheric Research and Max Planck Institute for Chemistry said the team’s research would help refine weather and climate models leading to better forecasts and projections.

Is tree planting overrated as a climate benefit? Researchers think so

Nature’s carbon cycle carries on regardless.
– – –
Roughly a third of the climate cooling that forests achieve by removing carbon dioxide (CO2) from the atmosphere is offset through changes to atmospheric composition and decreased surface reflectivity, researchers report.

The findings suggest that the benefits of wide-scale forestation efforts may be overestimated and do not represent a single solution for addressing climate change, says EurekAlert.

They also highlight the urgency of simultaneously focusing on emissions reductions. Planting trees has been widely promoted as a nature-based solution to remove anthropogenic CO2 from the atmosphere to help mitigate ongoing climate warming.

However, wide-scale forest expansion may drive feedbacks within the Earth system that lead to warming.

El Niño fading, ‘good chance’ of La Niña to follow says atmospheric physicist

Natural phenomena dictating weather patterns. The El Niño of 2023-24 is described as ‘strange’, possibly due to some extent to the Tonga undersea volcanic eruption of 2022.
– – –
Wild weather has been roiling North America for the past few months, thanks in part to a strong El Niño that sent temperatures surging in 2023, says The Conversation (via Phys.org).

The climate phenomenon fed atmospheric rivers drenching the West Coast and contributed to summer’s extreme heat in the South and Midwest and fall’s wet storms across the East.

That strong El Niño is now starting to weaken and will likely be gone by late spring 2024.
