Forecasting Bird Migration with Weather Radar and Models

From The Cliff Mass Weather Blog – Re-Blogged From WUWT

We are now in the midst of the big bird migration time of the year and weather radar can help documents the huge flux of birds overhead.

But even more fascinating, we can skillfully predict bird migration using numerical weather prediction.

One of my favorite sites  to check out bird migration is BirdCast, run by the Cornell Laboratory of Ornithology.  I really appreciate this group and as an undergrad at Cornell I frequently visited their Sapsucker Woods Wildlife Sanctuary.

The World’s First and Only “Climate Refugees” – Ancient Africans

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

It has been argued (unsuccessuly) that the current change in climate will cause millions to billions of “climate refugees”. Some of these claims have been so “over the top” that they were quietly withdrawn and swept under the rug. Here, we have a real case of climate refugees based on natural variation of the climate.

From the UNIVERSITY OF ARIZONA and the “natural variation before the SUV is wot dun it” department:

Ancient humans left Africa to escape drying climate

Humans migrated out of Africa as the climate shifted from wet to very dry about 60,000 years ago, according to research led by a University of Arizona geoscientist.

First Peoples: The Warming Alarm-Dog That Didn’t Bark

By Alec Rawls – Re-Blogged From http://www.WattsUpWithThat.com

Beneficial climate change allowed modern humans to emigrate out of Africa and spread around the globe says the new PBS documentary “First Peoples,” but it fails to mention that the era it designates as “good times” was several degrees warmer than today.

A critical moment in human history is intoned with intense drama (21:08-21:52 here):

The movement of prehistoric people was affected by the climate, which fluctuated over thousands of years.

I turned up the volume, knowing that if there was anything a warming alarm-dog could find to bark about, it was about to be featured front and center.

In bad times the Sahara was an un-crossable barrier, but in good times, when the climate was wet, the desert disappeared. Any adaption that emerged in one part of Africa could spread to other parts of the continent….
