Astronomy lectures and climate change

From the Silicon Valley Astronomy Lectures...a very interesting talk:

Take an entertaining and enlighting journey with astronomer and popular author Dr. David Grinspoon through the history of our solar system, discovering run away greenhouses and snowball planets. Compare the evolution of Venus, Earth, and Mars over the years and learn how studying the evolution of other planets can help us understand and predict climate change on Earth.

leading forward

One of the goals when teaching is to "lead forward'; that is create an
environment that sparks interest and wonder. If a teacher can manage to provide
a glimpse into the breathtaking world of life long learnig they are doing their
job.

The "thousand year model" is a great way to introduce astronomy to just
about any one and is an especially good "mini" field trip set up for school
kids. It creates an experiential excersize of our own solar system that seems to
stick with them.

Maybe you know some teachers who might be interested in it if they aren't already aware of it, but try it yourselves if you ever have some time to take a long walk -it's amazing!
