NOAA : Dust makes planets cold
(PhysOrg.com) — A new study led by the U.S, National Oceanic and Atmospheric Administration (NOAA) shows that tiny particles that make their way all the way up into the stratosphere may be offsetting a global rise in temperatures due to carbon emissions. And while scientists cannot yet say with any certainty where exactly the particles are coming from, they are saying that they have confidence that such particles have likely muted global temperature gains by as much as a third of what they would have been. They team, led by John Daniel, a physicist at the NOAA Earth System Research Laboratory (ESRL) in Boulder, CO, has published their results in Science.
Hansen : Dust makes planets very hot
“I decided to say that Venus was so hot because a dusty atmosphere was trapping internal heat,” he recalls. That was good enough for the doctoral committee”
CO2 has similar properties. It made snow a thing of the past while simultaneously producing record snowfall. It also causes record cold – when needed to keep funding going.
