Researchers say that leaded gas may have slowed global warming during the middle of the 20th century, New Scientist is reporting.
Lead particles in the atmosphere help form ice crystals, which help create clouds that aid global cooling by reflecting sunlight away from the planet.
The slowing of global warming between 1940 and 1980 may have been due to use of leaded gas, which was phased out because of air pollution concerns.
Soooo, lead is good? I’m confused.
I wonder if this will start a “leaden the air” movement.
When unleaded gas first became available, it cost more than leaded gas. But lead was an additive to gas, not a natural part of the refining process. They made us pay more for them NOT to do something. That’s genius.
