@hightor,
As far back as Great Gatsby, jerks with too much time on their hands thought maybe Earth was gonna fall into the sun. There's always prophecies.

In 1967, they thought all crops would die by 1975.
In 1969, everyone would turn to steam by 1989.
In 1970, there will be an ice age by 2000.
Also in 1970, they predicted water rationing by 1974 and food rationing by 1980.
In 1971, new ice age.
In 1972, they push back the ice age to 2070.
In 1974, another ice age?
In 1974, ozone depletion (we got rid of CFCs)
In 1976, the cooling.
In 1980, acid rain kills life in lakes (but 10 years later, they found it wasn't a problem)
In 1978, "no end to cooling trend" (but NASA found a slight warming trend)
In 1988, they forecasted a drought (but that was the last really dry year, followed by record wet)
In 1988, they predicted temperatures over 90 in Washington DC (notice the shift toward warming, after ice age predictions all failed), but the last truly warm year was way back in 1911.
In 1988, they predicted Maldives underwater in 30 years (2018, not 30 years from now)
In 1989, the rising seas will obliterate nations by 2000.
In 1989, NY West Side Highway underwater by 2019.
In 2000, children won't know what snow is.
In 2004, Britain will have Siberian climateby 2020.
In 2008, Arctic will be ice free by 2018. Also, Al Gore warns by 2013.
In 2009, we have just 8 years to save the planet.
In 2014, just 500 days to avoid climate change.
But the Earth is still standing.
And btw, no thanks to them. After the acid rain thing, we started making alot of plastic, because the paper mill acid was concerning people. Now plastic litters the oceans.
