A week ago,oilpan4 asked for some proof about this and a few other topics.I was reading the book,CENSORING SCIENCE,by physicist,Mark Bowen,2008,Dutton/Penguin,N.Y.,N.Y..,a little over 300-pages of text.
I'm just gonna put some dates and bullets up,and if anyone wants to discuss it,we can go from there.
*mid-Pliocene,about 3-million years ago,Earth is 3-C warmer,and sea-level 50-115-feet higher.
*18,000 years ago was last glacial maximum,at 4.5C (8F) cooler,with ave,global temp of 51-F.
*14,000 years ago,was the end of the glaciation,with sea-level rise of 3-feet,per twenty-years,for 400-years (15-feet/century).
*In 1784,Benjamin Franklin introduced the 'parasol effect',associated with atmospheric global dimming (dust and aerosols).
*1870 is considered 'pre-industrial',with atmospheric concentration of 280 ppmv,and average global temperature of 58-F.
*1870's global temperature without the atmosphere,= zero-F.
*1896,Svante Arrhenius connects man-made carbon dioxide with global warming.
*1961,meterologist,J.Murray Mitchell,U.S.Weather Service,introduces notion of
ast few decades of Earth cooling (global cooling).His data set is limited to
20-degrees North latitude and polewards,with no data from geographically below.The facts were: The entire northern hemisphere had warmed,and the rest of the world had warmed,from 1940-1961.
*1963-1965,Earth experiences three years of global cooling as a result of the parasol effect of dust and aerosols from the 1963 Mount Agung,volcanic eruption,Indonesia.
*1967,NASA begins its The Global Atmospheric Research Program
*1971,Rasool,and Schnieder,paper,Science,suggests 'global cooling', as a consequence of the parasil effect of the anthropogenic 'volcano',from tailpipes and smokestacks.As soon as it's published,Stephen Schneider discovers a mathematics error,but it's too late.
*1971,paper,Science,about atmospheric droplets in Venusian atmosphere,by John Lewis,MIT.
*1973,Hansen and Lacis,publish,solar radiation model for Earth.
*1974,Rowland and Molina make connection between DuPont 'Freon',and the ozone-hole.(CFCs are the strongest known greenhouse gas,plus they photo-chemically,biodegrade into chlorine,which destroys stratospheric atmospheric ozone,the only thing that protects us from lethal UV radiation.
*1974,Stephen Schneider,publishes his second Science article,correcting for his 1971 error,plus predicting that anthropogenic greenhouse gas-induced global warming will overtake anthropogenic global cooling soon after 1980.
*1975,Carl Sagan's,correct guess,that Venus's temperature is a function of a runaway greenhouse effect.
*1975,Hansen proposes a climate modelling brain trust at NASA.
*1975,Hansen is found to be correct in his theory of anthropogenic aerosol cooling.
*1976,Hansen is found to be correct in his theory about non-CO2,anthropogenic greenhouse gas warming.
*1976,Hansen is found to be correct in his theory of anthropogenic carbon dioxide greenhouse warming.
*1976,anthopogenic greenhouse warming is estimated at two-watts per square-meter surface heating,day and night.
*1976,Hansen et al,paper,Science,contains 'policy recommendations'!!!!!!!!!!
*1976,book,'The Weather Machine',by Nigel Calder,speaks of imminent ice age.
*July,1977,report: National Academy of Sciences,............. business-as-usual may lead to as much as eleven degrees-F warming,by 2050.
*July,1977,the hottest since the Dust Bowl.
*1978,NASA's Pioneer spacecraft mission-Venus,launch,with polarimeter,to measure atmospheric light scatter.
*1979,Hansen's group at NASA, Goddard Institute for Space Science,begins to assemble global temperature database.
*1980,record heat,ahead of Stephen Schneider's 1974 prediction.
*1981,Hansen et al., publish first comprehensive work on global warming,including 'guess' that anthopogenic non-carbon dioxide greenhouse gas effects,and parasol effects of anthropogenic aerosols are cancelling each other out.
*1981,Reagan-Bush appointee Fred Koomanoff,slashes Hansen's budget,requiring layoff of five scientists.
*1981,Reagan-Bush appointee,and lead climate skeptic,Michael MacCracken swings into action.
