Here’s a spooky graph of annual hours of sunshine on Krakow, in Poland. Hours of sunshine have been rising since 1980 — much like temperatures. It’s almost like CO2 has been irrelevant all along.
Thanks to Kenneth Richard at NoTricksZone. He writes that cloud cover changes are far more influential than man made CO2 is. The clouds have cleared over the last 46 years with the people of Krakow enjoying 500 more hours of sunlight each year and about 2.3°C of warming.
The research team, Marsz et al., 2025, estimate that radiative forcing by CO2 explained only 3.6% of the variance of temperatures, while changes in sunshine hours explained a whopping 58%.
Look at this graph~!
What if, all around the world, the clouds cleared in the last 40 years which let in more sunlight, and warmed the world, and all the carbon obessessed models were barking up the wrong tree. And the clouds in turn, were controlled by something like phytoplankton releasing cloud seeding particles, magnetic field changes, or jet streams shifting?
Kenneth Richard noticed another paper about Nigeria that reported a similar trend. And another in Brazil that showed that most regions also had less cloud cover now than they used to have.
In most regions of Brazil, sunshine hours are increasing

Looks like Good Science to me and no Modelling.

Less cloud results in lower night-time temperatures due to radiative energy loss. The paper is arguing that the temperature increase is partially due to change in cloud structure. This is likely a localised phenomena.

“Cloud condensation nucleus (CCN)—an atmospheric aerosol particle with a diameter typically less than 1 μm that facilitates the condensation of water vapor.
The presence of cloud condensation nuclei is essential for the formation of cloud droplets in the atmosphere and, consequently, for the formation of clouds themselves. The spontaneous coalescence of water molecules without the involvement of cloud condensation nuclei is highly unlikely and requires a partial pressure of water vapor many times greater than the saturated vapor pressure—conditions that practically never occur in the atmosphere.”
The main source of CCNs are organic sulfur compounds produced by oceanic phytoplankton:
“Marine phytoplankton produces DMSP (dimethylsulfonylpropionate), which breaks down into dimethyl sulfide (DMS). DMS is released into the atmosphere and initiates cloud formation, influencing the Earth’s climate.”

This was Lord Christopher Monckten’s thesis more than a decade ago. As likely as any other explanation for very slight warming of the ocean associated with very slight warming of the air and very slow monotonic increase in CO2 content. And not an End of Days alarmist religion like man made CO2 driven rapid tipping point Global Warming.
The imminent catastrophe was proposed by Al Gore in 1988 along with many, many predictions of disasters, all of which have proven wrong over 40 years. Comedy in 1990 It was funny at the time.
However Australian politicians and public service scientists don’t know how to take a joke. (BOM, CSIRO, Chief Scientist,Universities)
Meanwhile now billionaire and ex Vice President Al Gore is still laughing all the way to the bank. And invited to repeat his most famous tales of imminent disaster. For old times sake and a bit of a chuckle. Just like Snowy II, the greatest show in Australia since the Gold Rush of 1851 when 40% of the World’s gold came from Melbourne.

There is also a possible effect of pollution control, which started over 50 years ago.

My father came back from a trip to Los Angeles and complained that his eyes had watered all the 3 days there.

Sulfur compounds in the air are highly hygroscopic, which is why they serve as good condensation nuclei. It is likely that air ionization can also influence the formation of water droplets, just as the burning of coal and wood does.

The rise in temperature in a specific region of the continent is also influenced by the blocking of the zonal circulation. For example, this circulation is currently blocked over the Atlantic, where stationary low-pressure systems prevail and the surface temperature of the North Atlantic is low. In contrast, a high-pressure system formed by the jet stream prevails over Western Europe. The prolonged persistence of this high-pressure system allows the continental surface to heat up to extreme levels.
