In 1975, Newsweek — citing the supposed wisdom of scientists — warned of a “cooling world” and alluded to proposed remedies such as intentionally “melting the [Arctic] ice cap by covering it with black soot or diverting arctic rivers.” [some emphasis, links added]
This narrative, which was pushed in large part by the media, perished only to be replaced by another: global warming.
According to failed presidential candidate Al Gore and others, warmer temps not only meant more T-shirt weather but also polar bear drownings, rising sea levels, doom for coral reefs, and the melting of the North Polar ice cap.
Thankfully, New York City is not underwater, polar bears are prospering, coral reefs are more resilient than previously imagined, and the North Pole is doing just fine.
But the expert class whose prophecies appear to fall flat on a perennial basis now has a new worry. They have determined that the heat waves gripping Europe are not the result of a failure to stop emissions but of too much success.
A new study published in the American Geophysical Union’s peer-reviewed journal Geophysical Research Letters links the dramatic increase in summer temperatures over Europe, especially in the past decade, to the continent’s successful reduction of air pollution as part of initiatives aimed at tackling acid rain and “global warming.”
After four decades of increases, there was a “strong decrease” in sulfate aerosol emissions over Europe between 1980 and 2000, the study said.
The main human-caused source of sulfate aerosol emissions, which are also known as sulfur dioxide, is the sulfur content of fossil fuels released during combustion.
“The contribution of aerosols has a turning point around 1980, coinciding with a reduction of sulfate aerosol emissions over Europe resulting from the Montreal Protocol,” said the new study.
The Montreal Protocol was an international agreement focused on phasing out, globally, allegedly ozone-depleting substances, namely chlorofluorocarbons used in refrigeration, air conditioning, foam blowing, various aerosols, and other applications.
The treaty, which is the only universally ratified treaty in the United Nations’ history, went into force on Jan. 1, 1989.
While coinciding with the Montreal Protocol’s ratification, sulfate aerosol emissions were chiefly driven down in Europe — by an estimated 80% over the past three decades — as the result of other international protocols adopted across the continent, setting the stage for caps on industrial sulfur dioxide emissions, low-sulfur oil standards, new vehicle regulations, and the development of numerous desulfurization plants.
The study noted that “these changes have a direct impact on temperatures” — with temperatures negatively associated with aerosol levels.
Pedro Roldan-Gomez, an author of the paper who works as an earth sciences researcher at the Barcelona Supercomputing Center, told the Telegraph, “Now that the sulphates are disappearing over Europe we can see the full impact of the carbon dioxide emissions.”

Because Europe has already cut its total anthropogenic sulfur emissions by roughly 84% since 2005, each annual percentage drop removes a much smaller absolute mass of pollutants from the atmosphere compared to the large-scale reductions from 1980s to 2015.
The total decrease of air pollution since 1980 could have added 0.5 degree C. to the global average temperature. That could have caused a heat wave to be +0.5 degree C. warmer
This article is confusing climate and weather
2026 is not the first heat wave in Europe
Due to the long term trend of global warming (climate) heat waves (weather) are likely to get slightly warmer over time. This is not rocket science
