You do realize how completely full of shit you are, correct? Here is what Dr. Hansen published in 1981, the link leads to the full article, so you can educate yourself as to what the scientists were really stating in the '80's.No ,it isn't a clear and present danger. I have studied it.
It's about time we go back to the impending Ice Age as projected in the 80's.
Lots of folks have staked their careers on Global Warming/Climate Change/ hoopla ... Not like they are ever going to admit they might be a little off.
The same type folks that want to express driving a Prius here will go further towards fixing Global Warming than any of the other countries we share the globe with cleaning up their act.
It is all headed for United Nations bull ... Won't be long until we are trading Carbon Credits on Cricket Futures ... Cleaning up the air and feeding the poor at the same time.

Summary. The global temperature rose by 0.20C between the middle 1960's and
1980, yielding a warming of 0.4°C in the past century. This temperature increase is
consistent with the calculated greenhouse effect due to measured increases of
atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar
luminosity appear to be primary causes of observed fluctuations about the mean trend
of increasing temperature. It is shown that the anthropogenic carbon dioxide warming
should emerge from the noise level of natural climate variability by the end of the
century, and there is a high probability of warming in the 1980's. Potential effects on
climate in the 21st century include the creation of drought-prone regions in North
America and central Asia as part of a shifting of climatic zones, erosion of the West
Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the
fabled Northwest Passage.

Lacis, A., J. Hansen, P. Lee, T. Mitchell, and S. Lebedeff, 1981: Greenhouse effect of trace gases, 1970-1980. Geophys. Res. Lett., 8, 1035-1038, doi:10.1029/GL008i010p01035.
Increased abundances were measured for several trace atmospheric gases in the decade 1970-1980. The equilibrium greenhouse warming for the measured increments of CH4, chlorofluorocarbons and N2O is between 50% and 100% of the equilibrium warming for the measured increases of atmospheric CO2 during the same 10 years. The combined warming of CO2 and trace gases should exceed natural global temperature variability in the 1980s and cause the global mean temperature to rise above the maximum of the late 1930s.

And his predictions were 300% off while the CO2 levels were far higher than even he predicted. Not a source I would use.
