Ancient Landscapes Point to Dramatic Climate Change

By Tim Radford
Climate News Network

LONDON—Chinese and US scientists have uncovered prehistoric evidence of mass migration triggered by climate change.

Something occurred 4,200 years ago—a collapse of the monsoon system, the sapping of the groundwater, the sudden drainage of a lake—that brought a Neolithic culture to an end and left nothing but sandy landscapes in China’s Inner Mongolia region.

Archaeological evidence has revealed the jade carvings that once marked the Hongshan culture, along with evidence of hunting, fishing and even commercial traffic with Mongolian shepherds. And then the artefacts stop.

There is a 600-year period marked by no evidence of human settlement at all. Where there had once been streams, lakes grassland and forest, and a flourishing new Stone Age culture, only shifting sand dunes remained.

New Climate Change Study Calls For Urgent Action To Prepare NYC

Gothamist

We can keep debating global climate change (it's real!) until the last polar bear takes its final gasping breath. But let's never forget that this seaside city is in imminent danger—a new study confirms New York's temperatures are skyrocketing, sea levels are rising, and we're in for one hell of a grim ride.

The Mayor's Office has just released this year's incredibly bleak New York City Panel on Climate Change report today, noting that their findings "underscore the urgency of not only mitigating our contributions to climate change, but adapting our city to its risks." Not that this should be surprising at this point. Here are some fun things to look forward to, according to the report:

Mangled Jet Stream + Global Warming + Hot Atlantic Water = Boston Buried Under 8 Feet of Snow

Robert Scribbler

Boston just experienced its snowiest month on record and, yes, it really is climate change, stupid. In essence, as Michael Mann notes above, it’s a matter of oceanic and atmospheric physics.

Consider the fact that the ocean surface is warming at an unprecedented rate. Consider also the fact that this observed warming is resulting in a number of powerful south to north flows of air over ocean regions and toward the polar zone.

Hottest Year Ever

By Bruce Melton
Truthout
February 11, 2015

The last time we had this discussion was 2013, remember? Before that it was 2010. Before that it was 2005, and everything started with the Super El Nino in 1998. Statistically, saying that 2014 was the hottest year ever is a very valid thing, and if you understand statistics, I am envious of you.

But the global average temperature for these years, and every year since 1998 except 1999 and 2000, have all been virtually tied, if one is a casual civilian statistician watching or reading reporting on television or other media. But a few things have been overlooked in this and the periodic media outbursts that have preceded this event.

Climate Change Is Violence

By Rebecca Solnit, Trinity University

The following is an essay, "Climate Change Is Violence," from Solnit's anthology:

If you're poor, the only way you're likely to injure someone is the old traditional way: artisanal violence, we could call it— by hands, by knife, by club, or maybe modern hands-on violence, by gun or by car.

The Climate Science Behind New England’s Historic Blizzard

by Joe Romm
Think Progress
January 26, 2015

Another epic blizzard is bearing down on New England. There is a “big part” played by “human-induced climate change,” especially warming-fueled ocean temperatures, according to Dr. Kevin Trenberth, former head of the Climate Analysis Section at the National Center for Atmospheric Research.

I asked Dr. Trenberth to comment on the role climate change has on this latest storm, which is forecast to set records. He explained:

The number 1 cause of this is that it is winter. In winter it is cold over the continent. But it is warm over the oceans and the contrast between the cold continent and the warm Gulf Stream and surrounding waters is increasing. At present sea surface temperatures are more the 2F above normal over huge expanses (1000 miles) off the east coast and water vapor in the atmosphere is about 10% higher as a result. About half of this can be attributed to climate change.

This Map Shows Why The Midwest Is Screwed

The ongoing drought in California has been, among other things, a powerful lesson in how vulnerable America's agricultural sector is to climate change. Even if that drought wasn't specifically caused by man-made global warming, scientists have little doubt that droughts and heat waves are going to get more frequent and severe in important crop-growing regions. In California, the cost in 2014 was staggering: $2.2 billion in losses and added expenses, plus 17,000 lost jobs, according to a UC-Davis study.
