NASA climatologists DID make those claims, based on computer models by the same James Hansen who later discovered and warned Congress about global warming.

"If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age."
So YOU are exposed as the lying hate agitator.

"Hansen has advanced an alternative view of global warming wherein he
last 100 years has been driven mainly by greenhouse gases other than carbon dioxide (such as methane)."

"But we argue that rapid warming in recent decades has been driven mainly by non-CO2 greenhouse gases ..."
The spray can protesters may have been ignorant fools but professional NASA climatologists clearly DID warn of an Ice Age, based on Hansen's computer model of atmospheric radiative heat transfer.
Everything is getting mixed up here. The aerosols that Rasool and others were talking about are not from spray cans, but primarily from burning fuels and from volcanoes. Those aerosols -- silicates and sulfates for the most part -- generally reflect sunlight. Carbon particles, also considered to be aerosols, absorb sunlight. The models DID accurately predict a half-degree temperature drop after the Pinatubo eruption:

Rasool's 1971 paper said that CO2 caused surface warming, and that aerosols caused cooling. If the level of aerosols were multiplied by four, said Rasool, we could have an ice age (a highly speculative conclusion). That multiple of aerosol output did not happen. Instead, we have increases in CO2.
It also appears that Rasool's paper was inaccurate in predicting the effect of ever-higher levels of CO2. The self-limiting phenomenon that was predicted from the math has not been observed in reality.
And the burning wells of IRAQ and the neighboring country put up so much nasty sulfur and carbon that the warming chilled and moderated the effect. But we will be paying for that for years in pollution.
Yeah, there was... Came from the same kind of Government spawned lunatics that are now selling you the guilt trip of humans being the major contributor to Global warming. A little know secret is that the internet NG's are overloading the system causing all these problems.. ;-p
You are correct. I don't see why you started talking about silicon based life forms from space heating the planet so it's suitable for their species and then turn around and pretend you never mentioned it.
I'll just chalk it up as another symptom of your rather obvious mental problems. Don't worry about it; this is a very tolerant group.
Only among journalists and people with no connection to science. Here's most of the story:

Scientists dismissed it pretty quickly. Much of the chatter stemmed from Rasool's paper, which I mentioned before, and right-wing pundit Lowell Ponte's 1976 book, _The Cooling_. IIRC, it was a best-seller, and Ponte was on talk shows all over the airwaves.
Oh , and try reading the label on a can of spray anything ... or better yet , the msds for almost any pressurized can . EVERY ONE I looked up (and a couple that have it printed right on the can) shows butane/isobutane and/or propane as a propellant gas .
