National Post] An influential group of scientists led by James Hansen, the former NASA scientist often credited with having drawn the first major attention to climate change in 1988 congressional testimony, has published a dire climate study that suggests the impact of global warming will be quicker and more catastrophic than generally envisioned.
The research invokes collapsing ice sheets, violent megastorms and
even the hurling of boulders by giant waves in its quest to suggest that
even 2 degrees Celsius of global warming above pre-industrial levels
would be far too much. Hansen has called it the most important work he
has ever done.
The sweeping paper, 52 pages in length and with 19 authors, draws on
evidence from ancient climate change or “paleo-climatology,” as well as
climate experiments using computer models and some modern observations.
Calling it a “paper” really isn’t quite right – it’s actually a
synthesis of a wide range of old, and new, evidence.
“I think almost everybody who’s really familiar with both paleo and
modern is now very concerned that we are approaching, if we have not
passed, the points at which we have locked in really big changes for
young people and future generations,” Hansen said in an interview. Read More
