Non-Profit in the Spotlight: Aspen Global Change Institute - Part 4

In an effort to increase awareness and promote further academic understanding and research on global climate change, the Aspen Global Change Institute (AGCI) has teamed up with Colorado Mountain College to create an online database titled From the Horses Mouth. This resource is geared toward high school and undergraduate science classes. The database contains video and research from workshops and conferences hosted by AGCI. The subjects range from butterflies to atmospheric chemistry. 

Elise Osenga, a Research Associate for AGCI, and James Arnott, AGCI's Program Director, discuss the new database, its importance in the scientific community, and ways AGCI is looking forward and preparing for the uncertain future of climate change.

Climate Change and Conflict and the Media

ROGER ADAMS, HOST: Global temperatures on are the rise, and scientists predict that that will make for more extreme weather events—things like higher temperature spikes, drought, and more intense storms. And a team of researchers has made headlines by quantifying how much increased violence comes from extreme shifts in climate.

Aspen Public Radio’s science reporter Ellis Robinson, joins us on Valley Roundup. Hey Ellis.

The Water Delivery Man Problem

Optimal route for the 33-city traveling salesman problem in the 1962 Car 54 contest. Proctor & Gamble sponsored a $10,000 grand prize for the winning entry. Mathematicians Robert Karg and Gerald Thompson tied for first place.

There is a problem that has vexed mathematicians for the greater part of the past century. Currently, there is no solution, and nobody knows for certain whether or not one exists. But cracking the code would be a huge breakthrough both in theoretical mathematics and practical everyday applications. Ellis Robinson brings the story, starting with a description of the problem from physicist Eddie Farhi.

Study: River Forecasting in Rockies Needs Dusting

Dust on snow is easily visible to human eyes. And Satellites too. Burgess-Bryant is involved in a project that assesses dustfall on snowpack using satellite imagery.

Snow in the Upper Colorado River Basin provides water for seven states.  Farmers, factories, and families alike depend on this water, and a considerable amount of effort goes into understanding and forecasting how much melt is going to come from the snowpack, and when.

Geoengineering: The Technological Fix to Climate Change?

Schematic showing the major geoengineering strategies in the scientific literature. Among those discussed in this piece are aerosols in the stratosphere and iron fertilization of the oceans.

You may have missed it, but last week national headlines read, “the CIA wants to control the weather.”  Those headlines came on the heels of the media learning the CIA was funding a report on geoengineering. It’s an idea that’s akin to a man-made thermostat for the globe.  Aspen Public Radio’s Science Reporter explains what geoengineering is, why you need to know about it, and why the CIA is involved.
