Climate Change Links

Learn more about the history of the Earth’s climate and climate modeling at these online resources to go along with Episode 6 of Walkabout the Galaxy, our special Memorial Day discussion of global climate change.

There are a lot of excellent graphical representations of climate data at this site, aggregated from various source sites. http://www.skepticalscience.com/graphics.php

NASA’s climate science portal page is here.

This site addresses some of the common claims against evidence for global climate change or global warming. (You can also easily find on line roughly a gazillion sites providing arguments denying present or imminent climate change.)

The Intergovernmental Panel on Climate Change (IPCC) publishes exhaustive reports on climate change including analysis of climate data and model projections under a variety of different assumptions about future greenhouse gas emission. Their most recent report (AR5) is available at their site.

Episode 5: Crashing into the Moon, and a report from Vienna

Episode 5 goes live May 19, and Josh and Addie welcome Walkabout-er Tracy Becker for a discussion of the LADEE mission which recently expired by crashing onto the Moon. Josh describes getting lost at the European Geosciences Union meeting in Vienna and likens it to getting sliced into tiny pieces. Here’s a link to the movie Cube discussed before getting around to lunar science. Also hear Josh confuse Colorado with Central Florida. So embarrassing!

Saturn’s Dynamic Moons

Addie and Josh discuss two of Saturn’s 60-plus moons, and one of them may not even be a moon. Yet. Intrigued? Check out Episode 4, available now, to hear about the discovery of the subsurface water lake on the moon Enceladus and a baby moon named “Peggy”. Because what is more awesome than a baby moon named Peggy?

Odd Asteroids

In Episode 3, now available on iTunes, we welcome Professor Tom Statler (University of Ohio and University of Maryland) who tells the fascinating story of how sunlight can make an asteroid literally fly apart, and one was caught in the act by the Hubble Space Telescope. The process is called YORP, and yes, it does have to do with the Muppets. Also we ponder the amazing case of an outer-solar-system asteroid (a “Centaur”) that apparently has two narrow rings circling it.
