The Planet Cooled In June; Europe Maps The Heat Island; Hokkaido Joins The July Chill; + Rare Coastal Snow As South America Freezes

(July 3, 2026)

For all the media’s huffing and puffing over western Europe’s “climate-change heatwave,” the planet cooled in June.

UAH’s satellite-based lower troposphere record has June 2026 at +0.46C above the norm, down from +0.53C in May — a clear monthly fall all while headlines tried to turn one regional European hot spell into proof of a planetary catastrophe.

According to a World Weather Attribution report — and dutifully recycled by the usual activist rags — western Europe’s recent heatwave was “impossible without the climate crisis.”

Reuters led with the same line, adding that the “soaring night-time temperatures” were made 100 times more likely. The Guardian went further, calling it the “worst ever and impossible without climate crisis,” and claiming the heat was “only possible because of fossil-fuel burning.” Euronews warned that “climate change is running rampant,” while El País spelled out the sermon in its headline: “It’s not just hot, it’s climate change.” Etc. Etc. Etc.

The European heat was real. But it was weather. It was circulation. That is what blocking highs do.

Overall, the planet cooled 0.07C in June.

Fossil fuel emissions have rapidly worsened European heatwaves in just a few decades

(June 26, 2026)

Heatwaves pose a serious threat to human health and have profound impacts on ecosystems. During the summer of 2022, more than 60,000 people across Europe died as a result of extreme heat. Even in the following summer, which was significantly cooler, over 47,000 heat-related deaths were recorded (Gallo et al., 2024). Last year, the first heatwave in Europe, also hitting at the end of June, cost an estimated 2,300 people their lives in only 12 European cities (Grantham Institute, 2025).

Europe’s Deadly Heatwave: Climate Change Tripled the Death Toll, Finds Study

(July 11, 2025)

A searing heatwave that swept across parts of Europe in late June 2025 has been linked to nearly 2,300 excess deaths, according to a rapid attribution study conducted by scientists from Imperial College London and the London School of Hygiene & Tropical Medicine.

The analysis shows that global warming raised temperatures during this heatwave by 2 to 4°C above what they would have been in a world without human influence. This increase, though seemingly modest, had deadly consequences when combined with ageing infrastructure, dense urban environments, and inadequate heat preparedness in many parts of Europe. Temperatures soared well beyond seasonal norms, straining public health systems and exposing gaps in cities’ ability to protect residents.

Researchers focused on data from June 23 to July 2 and 12 European cities in Italy, Spain, Portugal, France, the UK, Greece, Croatia, and Hungary.

The Shrinking of the Heliosphere Due to Reduced Solar Wind

(December 2009)

Abstract. The heliosphere is the space within which the solar wind dominates and the solar interplanetary magnetic field prevails. Its boundary is determined by the balance between stellar and solar winds. Owing to the present reduction in the solar wind pressure, one would expect that the stellar wind would push the heliosphere inward leading to its shrinkage. In this paper we calculate the extent of the heliosphere at different solar wind status. Backward estimation of the extent of the heliosphere since 1890 is done. It is found that the heliosphere oscillated between 75 and 125 AU between 1890 – 2010. Most important is the forecast of the shrinkage and oscillations of the heliosphere and their implications on the earth. The shrinkage of the heliosphere would allow more invasions of cosmic rays to the earth and planets, increased cloud cover and a cooler Earth.

1.4 Prediction of the State of solar Activity During The Next Few Decades

Weak solar cycles occur at the bottom of Wolf-Gleissberg cycles. They tend to occur in series of 3-4 cycles. A single weak cycle also occurs in between the two maximums of Wolf-Gleissberg cycle. Since the last weak solar cycles occurred around 1900 while the previous ones occurred around 1800 then the newly started cycle 24 should be a weak solar cycle. However, owing to the 200-years de Verie cycle of the sun, it is more likely that the status of the coming solar activity would be something like those weak cycles around 1800 as shown in Fig 1. Svalgaard (2005) also predicted that cycle 24 would be the lowest so far in the past 100 years with the maximum sunspot number around 75.

Sun‘s protective ‚bubble‘ is shrinking

(October 18, 2008)

The scientists hope the IBEX mission will allow them to gain a better understanding of what happens at this boundary and help them predict what protection it will offer in the future.

Without the heliosphere the harmful intergalactic cosmic radiation would make life on Earth almost impossible by destroying DNA and making the climate uninhabitable.

Measurements made by the Ulysses deep space probe, which was launched in 1990 to orbit the sun, have shown that the pressure created inside the heliosphere by the solar wind has been decreasing.

Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 mT). The magnetic-field effect on CO2 solubility is twice as large, from which we surmise that geomagnetic field variations modulate the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic dipole moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

‘A wave of truth’: COP30 targets disinformation threat to climate action

Brazil’s President Luiz Inácio Lula da Silva set the tone at the opening session, declaring that the battle for truth has become just as critical as the fight to cut emissions. COP30 must mark “a new defeat for climate denialists,” he said.

On Wednesday, 12 nations – including Brazil, Canada, France, Germany and Spain – signed onto the first-ever Declaration on Information Integrity on Climate Change, pledging to fight back against the flood of false content and protect those on the frontlines of truth: environmental journalists, scientists and researchers.

The declaration, unveiled under the Global Initiative for Information Integrity on Climate Change, calls for concrete steps to dismantle networks of climate lies and shield evidence-based voices from harassment and attacks.

More than a planetary fender-bender: New study finds Earth collided with dense interstellar cloud, possibly affecting life on planet

(June 10, 2024)

Evidence of a long-ago collision involving the Earth was there in the form of specific radioactive isotopes deposited across the Earth and Moon. There were, however, skeptics.

But now researchers have tracked the sun’s path through the Milky Way back to a crash 2 to 3 million years ago with a dense interstellar cloud. The event was so violent it appears to have collapsed the sun’s protective bubble around the solar system and possibly even affected life on Earth.

(…)

“We don’t often discuss the impact of astrophysics on Earth because the astronomical timescales are very long, and the human species emerged on Earth just a few million years ago,” Loeb said. “But a few million years ago there was the potential for us to be passing through a very dense cloud. We didn’t work out the biological implications, but it’s clear that if you shrink the heliosphere to within the orbit of the Earth around the sun, we are not protected anymore. It could have significant implications for life on Earth.”

The fact that the MF effect is similar among the molecular gases suggests that effects seen with air are not due to the paramagnetic susceptibility of O 2, which is too small to explain the observed magnetic-field effects in terms of magnetization effects.

The technology: A solar panel that produces hydrogen

Air contains moisture. The water molecules in the air are captured by the panel when the airstream enters the device.

Solhyd technology can be applied in many locations around the globe. Only the most arid places on Earth are expected to be too dry for hydrogen panels to work efficiently.

Successful production of hydrogen panels

(November 15, 2024)

Solhyd not only develops technology to produce hydrogen from air and sunlight. We also develop methods to produce that technology in a cost-effective and reliable manner. Efficient production, with cost reductions driven by scale benefits, will eventually lead to the lowest cost approach to make hydrogen from solar energy.

We took the first step in that process this year.

Green energy breakthrough thanks to KU Leuven scientists

(02 October 2019)

For over a decade, Professor Johan Martens and Drs. Tom Bosserez, Jan Rongé and Christos Trompoukis have been developing a ‘solar hydrogen panel’, i.e. a solar panel that can create hydrogen from the water vapour in the air. Using sunlight, moisture taken from the air – i.e. no liquid water – is split into hydrogen on the one hand, and oxygen molecules on the other.

The panel is able to directly convert no less than 15 per cent of sunlight into hydrogen gas, Which is a world record

3 Things Scientists Need to Know About the IPCC

(September 1, 2015)

Now let’s take a look at point #2: Scientists are not in charge at the IPCC. Its latest report contains 60 chapters and totals more than 7,000 pages. Many good, sincere scientists toiled away on their own small portion of that enormous report. These people no doubt did their best to be honest and accurate.

But here’s the problem: almost no one will ever read that 7,000-page report. (…)

Everyone knows this. Which is why the IPCC also produces documents in the 20 to 30-page range bearing the title: Summary for Policymakers. (…)

In fact, IPCC authors only draft these summaries. And then something incredible transpires.
A big IPCC meeting takes place. Attended by governments. Although some people in the room are scientists, the vast majority are diplomats, politicians, foreign affairs specialists, bureaucrats, and assorted other officials. These people then spend the next week re-writing the summary authored by scientists.(…)

But the bad news doesn’t stop there. There’s actually a step in the IPCC process in which the original, lengthy report gets amended so that it conforms to the politically-negotiated Summary. I am not making this up.

Earth got hammered by cosmic rays 41,000 years ago due to a weak magnetic field

(24 April 2024)

The question is, Do periods of low magnetosphere intensity also correlate with major upheavals in Earth‘s biosphere, the complete zone of our planet over which life exists, ranging from mountaintops to the deepest ocean trenches?

„Understanding these extreme events is important for their occurrence in the future, space climate predictions, and assessing the effects on the environment and on the Earth system,“ Sanja Panovska, a scientist at GFZ Potsdam in Germany, said in a statement.

A global environmental crisis 42,000 years ago

(19 Feb 2021)

Do terrestrial geomagnetic field reversals have an effect on Earth‘s climate? Cooper et al. created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch. The authors modeled the consequences of this event and concluded that the geomagnetic field minimum caused substantial changes in atmospheric ozone concentration that drove synchronous global climate and environmental shifts.

(…)

We precisely characterize the geomagnetic reversal and perform global chemistry-climate modeling and detailed radiocarbon dating of paleoenvironmental records to investigate impacts. We find that geomagnetic field minima ~42 ka, in combination with Grand Solar Minima, caused substantial changes in atmospheric ozone concentration and circulation, driving synchronous global climate shifts that caused major environmental changes, extinction events, and transformations in the archaeological record.

(…)

In addition, chronological uncertainties are complicated in radiocarbon-dated terrestrial and marine records around the Laschamps because of the elevated production of C and Be, cosmogenic radionuclides resulting from the substantial increase in high-energy cosmic radiation reaching the upper atmosphere. The high Be flux has been well described from Greenland and Antarctic ice core records (6, 20, 21), which reveal synchronous century-long Be peaks across the Laschamps that appear to reflect a series of pronounced Grand Solar Minima (GSM; prolonged periods of low solar activity similar to the Spörer and Maunder Minima: 1410 to 1540 CE and 1645 to 1715 CE), with unknown climate impacts (20, 21).

Effects of Earth’s magnetic field — Science News, November 21, 1970

„Earth’s magnetic field has frequently reversed at intervals of 1 million to 100 million years. A few scientists now suspect that these reversals may have had drastic effects on terrestrial life.… During the past 2.5 million years, eight species of one-cell marine animals called Radiolaria became extinct. Six of these extinctions occurred simultaneously throughout their geographic range immediately following magnetic reversals.“

Scientists link Earth’s magnetic reversals to changes in planet’s life and climate

(April 19, 2021)

The researchers examined the rings of the tree to look for changes in the amount of carbon-14 over a period of years, Gramling explains. Carbon-14 is useful not only for dating things, but because the interaction of cosmic rays with molecules in the atmosphere produces a lot of it. And when the Earth has a weakened magnetic field, more cosmic rays hit the planet.

The scientists indeed found a large spike in carbon-14 in the tree, which they could then compare with the rock record that indicated a magnetic reversal. (…)

In addition, there is the documented rise in cave art right about 41,000-42,000 years ago, Gramling points out.

Possible Eoarchean Records of the Geomagnetic Field Preserved in the Isua Supracrustal Belt, Southern West Greenland

(24 April 2024)

The preservation of a temperate climate and liquid water on early Earth depends critically upon the strength of the magnetosphere (Sterenborg et al., 2011; Tarduno et al., 2014). Recent atmospheric escape models have suggested that both weak (<10 μT) and strong (>1 mT) magnetic fields could substantially enhance atmospheric escape under present-day solar wind conditions via the polar wind or cusp escape, respectively (Gronoff et al., 2020; Gunell et al., 2018; Lundin et al., 2007). During the Archean, the Sun was rotating faster, generating a stronger stellar dynamo and therefore the solar wind was more intense than today (Vidotto, 2021). An increased solar wind strength causes greater interaction with the upper atmosphere and greater escape of ions assuming a constant level of protection from Earth‘s magnetosphere. Previous magnetohydrodynamic simulations have suggested that if Earth‘s magnetic field was half its present day strength 3.5 Ga ago, the area of the polar cap (the area containing open dipolar magnetic field lines, allowing atmospheric escape via the polar wind) could increase by up to 50% (Sterenborg et al., 2011).

The Earth’s Magnetic Field Is At Least 3.7-Billion-Years Old, New Evidence Shows

The age of the Earth’s magnetic field remains under question in part because we don’t fully understand what causes it today. We know it is a product of movements in the molten outer core, whose high iron content turns convection currents into a dynamo, and these currents in turn are produced by the solidification of the inner core.

Earth‘s magnetic field formed before the planet‘s core, study suggests

(24 April 2024)

Today, the magnetic field is driven by the churning of the liquid part of the core and the transfer of heat from the solid inner core to the convective outer core as the former cools. But researchers think the core didn‘t solidify until about a billion years ago.

25.04.2024 - 23:40 [ United States Geological Survey ]

How does the Earth‘s core generate a magnetic field?

The Earth‘s outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. This sets up a process that is a bit like a naturally occurring electrical generator, where the convective kinetic energy is converted to electrical and magnetic energy. Basically, the motion of the electrically conducting iron in the presence of the Earth‘s magnetic field induces electric currents. Those electric currents generate their own magnetic field, and as the result of this internal feedback, the process is self-sustaining so long as there is an energy source sufficient to maintain convection.
