NASA Discovers 'Twilight Zone' of New Air Particles

An extensive and previously unknown "twilight zone" of particles in the atmosphere could complicate scientists' efforts to determine how much the Earth's climate will warm in the future, a new study finds.

"The effects of this zone are not included in most computer models that estimate the impact of aerosols on climate," said lead author Ilan Koren of the Weizmann Institute of Science, in Israel. "This could be one of the reasons why current measurements of this effect don't match our model estimates."
