Scientists have discovered a major paradox in nature: clean air promotes global warming, while pollution keeps our planet cool.
A team of international researchers has found that today’s pollution rates are 30 percent lower than in 2000, but global warming from the emission of carbon dioxide has increased by as much as 50 percent.
Pollutant particles, such as sulfates or nitrates, are known for their reflective properties and are most commonly found in exhaust gases.
The team desperately proposes to use aerosols again, using a controversial form of geoengineering.
Called solar engineering, this method involves releasing sulfate particles into the stratosphere, which in turn will cause reflective haze around the world, Science.org reports.
The study, led by the University of Leipzig, offers good news for human health – these particles are linked to millions of deaths each year – but is bleak for what the future holds for humanity.

While pollution has fallen by 20% since 2000, global warming from carbon emissions has increased
The team found that ocean temperatures have been rising since 2000, which they say is again because the world has adopted policies that reduce the use of aerosols.
Johannes Coas, a climate scientist at the University of Leipzig and lead author of the study, told Science.org that the study was conducted with instruments on NASA’s Terra and Aqua moons, both of which collect data on Earth’s atmosphere.
These devices also collect information about radiation entering and exiting the Earth, which helps research understand the increase in infrared heat held by greenhouse gases.
Another instrument on satellites showed a decrease in reflected light coming from Earth.

Venkachalam Ramaswamy, director of the National Oceanic and Atmospheric Administration Laboratory of Geophysical Fluid Dynamics, told Science.org that there can only be one explanation for this: cleaner air. Dynamic laboratory. “It is very difficult to find alternative causes for this,” he said.
With all this data, the team was able to analyze haze in the atmosphere, which allowed them to identify the haze over North America, Europe and East Asia that had largely cleared between 2000 and 2019.
The findings led to the idea of sending pollutant particles back into the atmosphere, which would in turn reflect solar radiation back into space and ultimately limit or reverse anthropogenic climate change.
The team desperately proposes to recycle aerosols, but to use controversial geoengineering in the process. This method was proposed by the Stratospheric Controlled Turbulence Experiment, which is funded by Microsoft founder Bill Gates.

This first $3 million test will use a high-altitude scientific balloon to lift about four pounds of calcium carbonate dust — the size of a minute bag — into the atmosphere 20 miles above the New Mexico desert.
This would sow a tubular field half a mile long and 100 yards in diameter.
Over the next 24 hours, the balloon will again be guided through this artificial cloud by propellers as onboard sensors monitor the dust’s ability to reflect the sun and its effect on the thin surrounding air.
However, SCoPEx has been put on hold for fear that it could set off a catastrophic chain reaction, causing climate devastation in the form of severe droughts and hurricanes, killing millions of people around the world.
