SHOCK: The ‘Father of global warming’, James Hansen, dials back alarm
James Hansen: We Have a Little More Time After All (Whew!)
By Robert Bradley Jr.
“Contrary to the impression favored by governments, the corner has not been turned toward declining emissions and GHG amounts…. Negative CO2 emissions, i. e., extraction of CO2 from the air, is now required.”
– James Hansen, “Young People’s Burden.” October 4, 2016.
“The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts.”
What a difference a few months make!
Just in time for holiday season, and for the Trump Administration, the father of the climate alarm, formerly a climate scientist with NASA/GISS, and now a full-time scientist/activist, has ameliorated his grand climate alarm. The 10-year ultimatum announced in 2006, made more dire in 2009 and since, is now moderated.
The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts. However, despite uncertainties about some climate processes, we know enough to say that the time scale on which we must begin to reduce atmospheric GHG amounts is measured in decades, not centuries. Given the fact that the fastest time scale to replace energy systems is decades, that means that we must get the political processes moving now. And that won’t happen until the public has understanding of what is actually needed and demands it.
