It’s hard for the average citizen to read the news these days and not be worried for the future of the planet. We are told that 13 of the last 16 years have been the warmest on record. We hear that coastal cities such as New York and Atlantic City, as well as nearly all of Florida, are at risk of flooding due to unprecedented sea-level rise. We are told that the wildfires in California and Greece are the worst ever recorded, and that these fires represent a “new normal” because of man-made climate change.
But to get a good gauge of such predictions, it is wise to look at how similar predictions have turned out in the past. So, don’t sell your beachfront property just yet.
Beginning back in 1988, certain scientists have been predicting climate doom, some of which should already be evident. That was the year when James Hansen, then the head of the NASA Goddard Institute for Space Studies, testified before Congress that the greenhouse effect was causing warming on Earth and that man was at least partially responsible for it.
“Global warming has reached a level such that we can ascribe with a high degree of confidence a cause and effect relationship between the greenhouse effect and observed warming,” Hansen told Congress. “It’s already happening now.”
