Opinion | A Prophet of Doom James Hanson Was Right About the Climate – by Justin Gillis – NYT

“June 23 turned out be a blistering day in Washington, and much of the nation was suffering through a drought and heat wave. Dr. Hansen took his seat in a Capitol Hill hearing room and laid out the scientific facts as best he understood them.He had thought up a good line the night before, during the Yankees game, but in the moment he forgot to deliver it.

When the hearing ended, though, reporters surrounded him, and he remembered.  “It is time to stop waffling so much,” he said, “and say that the evidence is pretty strong that the greenhouse effect is here.”

His near certainty that human emissions were already altering the climate caught the attention of a sweltering nation, catapulting Dr. Hansen to overnight fame. That year, 1988, would go on to be the hottest in a global temperature record stretching back to the 19th century.With the perspective of three decades, it is fair to ask: How right was his forecast?”

. . . .

“So while his temperature forecast was not flawless, in a larger sense, Dr. Hansen’s 1988 warning has turned out to be entirely on target. As emissions have soared, the planet has warmed relentlessly, just as he said it would; 1988 is not even in the top 20 warmest years now. Every year of this century has been hotter.

The ocean is rising, as Dr. Hansen predicted, and the pace seems to be accelerating. The great ice sheets in Greenland and Antarctica are dumping ever-rising volumes of water into the sea. Coastal flooding is increasing rapidly in the United States. The Arctic Ocean ice cap has shrunk drastically.

If his warning in 1988 had been met with a national policy to reduce emissions, other countries might have followed, and the world would be in much better shape.      . . . . “

David Lindsay:  Thank you Justin Gillis. Here is one of my favorite comments at the NYT.com:

Words don’t quite convey just how accurate Hansen’s predictions were. See
http://www.realclimate.org/index.php/archives/2018/06/30-years-after-han…
for a graph comparing his three scenarios with what actually happened. How anyone can look at that graph and claim Hansen was “wrong” in his predictions, as several commenters here have already done, is beyond me. Science is not a matter of opinion. Human-caused climate change is as real and undeniable as gravity.
