What happened to the settled science? Of course the spin will be that only refinements are needed, which call for more data, but that suggests a measure of uncertainty that isn’t supposed to exist. Climate theory can be something of a shapeshifter when results aren’t as per alarmist forecast.

NASA’s Earth System Explorers Program selected four proposals to study greenhouse gases, the ozone layer, ocean currents, and ice changes, says NASA/JPL (via SciTechDaily).

Each will get $5 million for a one-year study before NASA picks two for future launches.

Four proposals have been selected by NASA for concept studies of missions to help us better understand Earth science key focus areas for the benefit of all, including greenhouse gases, the ozone layer, ocean surface currents, and changes in ice and glaciers around the world.

It turns out that ‘Until now the models that climate change scientists used to gauge heat loss were based on theories rather than real observations’. In other words, little or no data from the polar regions, so claims of Earth ‘overheating’ are lacking vital information. SciTech Daily says: ‘The PREFIRE CubeSats use advances in spectrometry to measure processes associated with ice melt and formation, snow melt and accumulation, and changes in cloud cover.’

A tiny NASA satellite was launched Saturday from New Zealand with the mission of improving climate change prediction by measuring heat escaping from Earth’s poles for the first time, says Phys.org.

“This new information—and we’ve never had it before—will improve our ability to model what’s happening in the poles, what’s happening in climate,” NASA’s earth sciences research director Karen St. Germain told a recent news conference.

The satellite, which is the size of a shoe box, was launched by an Electron rocket, built by a company called Rocket Lab, which lifted off from Mahia in the north of New Zealand. The overall mission is called PREFIRE.

Let’s hope this is not going to be used as another excuse to pretend alarmist predictions from climate models have improved, just because some extra data is being fed in.

A brand new satellite that will revolutionize our understanding of the role clouds and aerosol particles play in climate change is set to launch after more than 30 years of planning, says the University of Reading (via Phys.org).

The EarthCARE satellite is the brainchild of the University of Reading’s Professor Anthony Illingworth. Conceived in 1993, the project was adopted by the European Space Agency (ESA) in 2004.

The satellite is set to blast off from California’s Vandenberg Space Force Base on board one of Elon Musk’s SpaceX rockets, scheduled for launch no earlier than Tuesday 28 May 2024.

The mission is a testament to the power of U.K. and international collaboration and the importance of long-term, dedicated research. The satellite, equipped with four cutting-edge instruments, will provide unprecedented insights into the complex interactions between clouds, aerosols, and Earth’s climate.

This data will be invaluable in shaping our understanding of climate change and informing future climate adaptation and mitigation policies.

Professor Anthony Illingworth, Professor of Atmospheric Physics at the University of Reading, said, “When we first started dreaming up this project, I never imagined I would be flying out to the United States to watch our satellite launch 30 years later.

“It’s been a long and challenging journey with an amazing team of dedicated scientists and engineers from the U.K. and abroad. Together, we’ve created something truly remarkable that will change the way we understand our planet.

“The data we gather from EarthCARE will be invaluable in helping us observe the precise mechanisms involved in how clouds and dust reflect and absorb heat. This will make our predictions for the future of our climate even more precise, meaning we can make more informed decisions about how to mitigate and adapt to the challenges posed by a warming world.

“The extraordinary data we receive will help us create a more sustainable future for our planet. It’s a humbling and thrilling experience to be part of something so significant.”

Currently, climate models do not agree on how effective clouds and aerosols are at influencing the impact of global warming. For example, if there were fewer cloudy days in the future, less energy from the sun would be reflected back into space, which would increase the rate of climate warming.

EarthCARE’s new observations will help scientists to develop more precise climate models, which will significantly improve climate predictions and lead to more informed policy decisions.

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 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.

The research, titled ‘Clouds dissipate quickly during solar eclipses as the land surface cools’, suggests interfering with solar radiation to try and weaken natural warming would be even riskier than previously thought.
– – –
Cumulus clouds over land start to disappear almost instantly during a partial solar eclipse, says Phys.org.

Until recently, satellite measurements during the eclipse resulted in dark spots in the cloud map, but researchers from TU Delft and KNMI were able to recover the satellite measurements by using a new method.

The results may have implications for proposed climate engineering ideas because disappearing clouds can partly oppose the cooling effect of artificial solar eclipses.

One overlooked factor was the CO2 fertilization effect in plant photosynthesis. The researchers found that “it’s virtually impossible to predict soil moisture in the coming decades”, contrary to some alarmist notions about future droughts.
– – –
Soil moisture can determine how quickly a wildfire spreads, how fast a hill turns into a mudslide and, perhaps most importantly, how productive our food systems are, says Eurekalert.

As temperatures rise due to human-caused climate change [Talkshop comment – evidence-free assertion of cause], some researchers are concerned that soils will dry.

However, between 2011 to 2020, soil moisture increased across 57% of the United States during summer, the warmest time of year.

Why did soil get wetter even as the planet got hotter?

Will Satellite Megaconstellations Weaken Earth’s Magnetic Field?

Researcher: “We absolutely cannot dump endless amounts of conductive dust into the magnetosphere and not expect some kind of impact. Multidisciplinary studies of this pollution are urgently needed.”

Artificial Re-entry Plasma Dust


This must put a dent in the credibility of at least some supposedly climate-related satellite data. On the positive side, a significant chunk of the alleged global carbon dioxide problem disappears, as the carbon cycle of a large region turns out to be self-balancing. The CO2 struck off, so to speak, is ‘equivalent to about 10% of annual emissions from the burning of fossil fuels’.
– – –
The forests and grasslands of northern tropical Africa take in about as much carbon dioxide in the wet season as they release in the dry season, according to a new study based on observations from aircraft.

The findings contradict earlier research that relied on satellite data and found that these ecosystems may be adding significantly more carbon to the atmosphere than they absorb over the course of a year, says Phys.org.

The research, published in the journal Global Biogeochemical Cycles, highlights the difficulty of measuring carbon dioxide from space and the need for more frequent and robust observations from both the air and ground.

Antarctica [credit: Wikipedia]


The BBC once again trying to pull the wool over the unsuspecting public’s eyes on climate? Surely not! Or…guilty as charged? With Arctic sea ice scare stories looking increasingly hollow, something along apparently similar lines at the other end of the globe proved irresistible.
– – –
Antarctica sea ice is at a “mind-blowing” record low winter area of 17 million square kilometres, reports a three-person BBC “News Climate & Science and Data Journalism Team”, as lower levels than those recorded in the recent past provide the cue for yet more media climate hysteria, says The Daily Sceptic.

Of course, the BBC headline is clickbait nonsense, not least because it has been generally known in scientific circles that early NASA Nimbus satellites showed even lower winter levels around 15 million sq. kms in 1966.

But the BBC story does provide an excellent example of how science is twisted to fit the political narrative supporting the collectivist Net Zero agenda.

Urban heat island effect


The study, entitled The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data (August 2023), has 40 authors, some of whom are regular contributors to the ‘climate debate’ both in published papers and elsewhere. It takes a critical look at recent IPCC reports and summaries, especially the quality or otherwise of some of the data used to support its assertions. It suggests ways some of these issues could/should be addressed. Below is the abstract and the closing summary.
– – –
Abstract
A statistical analysis was applied to Northern Hemisphere land surface temperatures (1850–2018) to try to identify the main drivers of the observed warming since the mid-19th century.

Two different temperature estimates were considered—a rural and urban blend (that matches almost exactly with most current estimates) and a rural-only estimate. The rural and urban blend indicates a long-term warming of 0.89 °C/century since 1850, while the rural-only indicates 0.55 °C/century.

This contradicts a common assumption that current thermometer-based global temperature indices are relatively unaffected by urban warming biases.

Alaskan dust storm [image credit: NASA]


Although this was already a known effect to some extent, the new research suggests the effect is ‘bigger than previously thought’. Anything linked to cloud formation is significant, including for climate modellers.
– – –
Giant dust storms in the Gulf of Alaska can last for many days and send tons of fine sediment or silt into the atmosphere, and it is having an impact on the global climate system, say scientists.

The storms are so extensive they can be seen by satellites orbiting the Earth, reports Phys.org. An image captured by the Landsat satellite in 2020 shows dust blowing out of the valley and over Alaska’s south coast.

Exactly how the dust may be influencing the global climate system is not yet clear, although new research from the University of Leeds and the National Center for Atmospheric Science suggests the effect is bigger than previously thought.

Andes mountain range


We’re told ‘the exact cause or resulting consequences of this greening are not known’, but the media spin says ‘it’s not good news’. The unhealthy obsession with climate gloom and doom in certain quarters has spilled over here. The massive and ongoing greening trend is decribed as ‘a warning sign, like the canary in the mine’ (which of course expires). Really?
– – –
Research led by physicists and geographers at the University of Cambridge has unveiled some large-scale changes in the vegetation in the South American Andes which may have dramatic impact on the environment and ecosystems of the region, says Phys.org.

Analyzing satellite data spanning the past 20 years, the research team based at the Cavendish Laboratory in Cambridge examined how vegetation has been changing along the Pacific coast of Peru and northern Chile.

This area is known for its unique and delicate arid and semi-arid environments.

Volcanic eruption


The idea proposed here of climate model forecasts becoming ‘more robust’ by including smaller effects depends on them being robust to some degree in the first place, which is open to question given their output to date.
– – –
Researchers have found that the cooling effect that volcanic eruptions have on Earth’s surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections, says Phys.org.

While this effect is far from enough to offset the effects of global temperature rise caused by human activity [Talkshop comment – unsupported assertion], the researchers, led by the University of Cambridge, say that small-magnitude eruptions are responsible for as much as half of all the sulfur gases emitted into the upper atmosphere by volcanoes.

The results, reported in the journal Geophysical Research Letters, suggest that improving the representation of volcanic eruptions of all magnitudes will in turn make climate projections more robust.

Dr Mike McCulloch has been making truly remarkable discoveries about some of the mysteries of the cosmos over the last two decades. He has answers to fundamental questions such as ‘what causes the force that resists the change in speed and direction of any mass?’, ‘why do observations indicate that the inertial force varies with acceleration in the outer reaches of galaxies?’ and ‘how can we tap into the implicated energy fields to generate propellant-less thrust, and potentially generate electrical energy to power our homes, industries and vehicles?’. His published papers cover the first two of these questions, and touch on the third, although there’s plenty more to be teased out of the implications of his Quantised Inertia theory. The third question is the acid test.

Mike believes science has to have practical, applicable results, and for the last few years, he has been successfully generating those at his lab in Plymouth University, funded by DARPA. He has been getting measurable thrust from purely electrical input. Other collaborating labs have similar results. Exciting times indeed.

But like many scientists who threaten the established and accepted theory in their field, his work has been largely ignored because it falsifies mainstream ‘dark matter’ theory, or dismissed because it ‘must be impossible’. Although he has got measurable results, DARPA funding is ending, and he has no more teaching work to return to at Plymouth University. Mike wants, as far as possible, to keep the ongoing developments of QI publicly accessible, by crowdfunding. He needs our help to fund and equip a new lab, and set up a ‘Horizon Institute’, online initially, to enable the collaboration of academics and citizen scientists. Please read his message below, and then I’ll let you know how you can help.

Climate miserablists are no doubt dreaming of a mega El Niño to get their warming scare back on course.

Science Matters

The post below updates the UAH record of air temperatures over land and ocean.  But as an overview consider how recent rapid cooling  completely overcame the warming from the last 3 El Ninos (1998, 2010 and 2016).  The UAH record shows that the effects of the last one were gone as of April 2021, again in November 2021, and in February and June 2022  Now at year end 2022 and continuing into January 2023 we have again global temp anomaly lower than average since 1995. (UAH baseline is now 1991-2020).

For reference I added an overlay of CO2 annual concentrations as measured at Mauna Loa.  While temperatures fluctuated up and down ending flat, CO2 went up steadily by ~60 ppm, a 15% increase.

Furthermore, going back to previous warmings prior to the satellite record shows that the entire rise of 0.8C since 1947 is due to oceanic, not human activity.

Has the mystery been solved?
– – –
When looking at the Earth from space, its hemispheres – northern and southern – appear equally bright, says EurekAlert.

This is particularly unexpected because the Southern Hemisphere is mostly covered with dark oceans, whereas the Northern Hemisphere has a vast land area that is much brighter than these oceans.

For years, the brightness symmetry between hemispheres remained a mystery.

What was the point of all those UN climate conferences again?

Preliminary analyses of global satellite data by environmental researchers at the University of Bremen show that atmospheric concentrations of the two important greenhouse gases carbon dioxide (CO2) and methane (CH4) continued to rise sharply in 2022, reports Phys.org.

The increase in both gases is similar to that of previous years. However, the increase in methane does not reach the record levels of 2020 and 2021.

The Institute of Environmental Physics (IUP) at the University of Bremen is a world-leading institute in the field of evaluation and interpretation of global satellite measurements of the greenhouse gases carbon dioxide (CO2) and methane (CH4) and other atmospheric trace gases that are of great importance for climate and air quality.

The institute leads the GHG-CCI greenhouse gas project of the European Space Agency’s Climate Change Initiative (ESA) and provides related data to the European Copernicus Climate Change Service C3S and the Copernicus Atmospheric Monitoring Service CAMS.

Collecting mountains of data on so-called greenhouse gases was not going to be cost-effective, says NASA. ‘Technical concerns’ played a part in the decision.

All good things must come to an end, and in the case of NASA’s GeoCarb mission, some good things must end before they really begin, says Space.com.

NASA has canceled the GeoCarb mission, which was a collaboration with the University of Oklahoma and Lockheed Martin that intended to put a greenhouse gas–monitoring satellite into geostationary orbit.

GeoCarb would have measured levels of carbon dioxide, carbon monoxide and methane in the atmosphere about 4 million times per day. The mission was selected by NASA in 2016.

Space satellite orbiting the earth


An academic attempt to gloss over some glaring discrepancies between results from theory-based climate models and observed data. The research paper says: ‘Climate-model simulations exhibit approximately two times more tropical tropospheric warming than satellite observations since 1979’. Over forty years of being so wrong, by their own admission, takes a lot of explaining.
– – –
Satellite observations and computer simulations are important tools for understanding past changes in Earth’s climate and for projecting future changes, says Lawrence Livermore National Laboratory (via Phys.org).

However, satellite observations consistently show less warming than climate model simulations from 1979 to the present, especially in the tropical troposphere (the lowest ~15 km of Earth’s atmosphere).

This difference has raised concerns that models may overstate future temperature changes.
