Hansen devoted his career at NASA
to researching climate change. |
In the late 1980s, James Hansen became the first
scientist to offer unassailable evidence that burning fossil fuels is
heating up the planet.
In the decades since, as the world has warmed, the ice has
melted and the wildfires have spread, he has published papers on everything
from the risks of rapid sea-level rise to the role of soot in global
temperature changes – all of it highlighting, methodically and verifiably, that
our fossil-fuel-powered civilisation is a suicide machine.
And unlike some scientists, Hansen was never content to hide
in his office at NASA, where he was head of the Goddard Institute for Space
Studies in New York for nearly 35 years. He has testified before Congress,
marched in rallies and participated in protests against the Keystone XL
Pipeline and Big Coal (he went so far as to call coal trains "death
trains"). When I ran into him at an anti-coal rally in Washington, D.C.,
in 2009, he was wearing a trench coat and a floppy boater hat. I asked him,
"Are you ready to get arrested?" He looked a bit uneasy, but then
smiled and said, "If that's what it takes."
