Heat and History

October 24, 2013

“And it is really in the past 20 years that the warming signal from that region has been just stunning,” he added. “All of Baffin Island is melting, and we expect all of the ice caps to eventually disappear, even if there is no additional warming.”

Hottest it’s been up there in a way-long time.

Like maybe, 120,000 years? And the big heat just started about a century ago, excelerated in the 1970s, and is tripping right along into the nowadays — some new research joins the rising number of the quicker-than-we-first-figured genre.
The guy quoted above is Gifford Miller, a researcher at the University of Colorado, Boulder, and lead author of the new study published online in Geophysical Research Letters.
Climate change is bringing change — warmth.
From UPI:

Since Earth was in a long glaciation period prior to that time, it means Canadian Arctic temperatures today likely have not been matched or exceeded for roughly 120,000 years, Miller said.
“The key piece here is just how unprecedented the warming of arctic Canada is,” he (Miller) said.
“This study really says the warming we are seeing is outside any kind of known natural variability, and it has to be due to increased greenhouse gases in the atmosphere.”
Temperatures across the Arctic have been rising substantially in recent decades as a result of the buildup of greenhouse gases in Earth’s atmosphere, the researchers said.
Previous studies by CU-Boulder scientists in Greenland found temperatures on the ice sheet have climbed 7 degrees Fahrenheit since 1991.

Despite all this “unprecedented” heat in the Arctic region, supposedly the tropics will be the first area to get smacked hard by climate change. Another study earlier this month raised alarms about the speed of change on the equator and thereabouts. Published in Nature, the report concluded: Unprecedented climates will occur earliest in the tropics and among low-income countries, highlighting the vulnerability of global biodiversity and the limited governmental capacity to respond to the impacts of climate change.
Soon, the consequences for all humanity.
From the LA Times:

“Regardless of the scenario, changes will be coming soon,” said Camilo Mora, an assistant professor of geography at the University of Hawaii, Manoa, and the study’s lead author.
“Within my generation, whatever climate we were used to will be a thing of the past.”

History has finally caught up with us.
