Russian scientists have discovered that volcanic particles can help cool the Earth, a leading environmental scientist said yesterday. The world's temperature can drop 0.5 to 1 C a year if 1 ...

Scientists Resort to Once-Unthinkable Solutions to Cool the Planet Three geoengineering projects seek to alter the chemistry of the atmosphere and the ocean. Critics warn of unintended consequences.

And small particles are the worst: “particles less than 2.5 micrometers in diameter, also known as fine particles or PM2.5, pose the greatest risk to health,” according to the EPA.
