Celebrate Earth Day with and#8216;How Scientists are Making a Differenceand#8217;

OLYMPIC VALLEY, Calif. and#8212; In celebration of Earth Day, Squaw Valley Institute will present a discussion titled and#8220;How Scientists Study the Earthand#8217;s Biosphere and are Making A Differenceand#8221; with Doug Helmuth, Wednesday, April 20 at Resort at Squaw Creek, Olympic Valley. Doors open at 6:30 p.m., a no-host bar will be offered.

Last yearand#8217;s Earth Day presentation provided some fundamentals of satellite climate monitoring, historical perspectives of how and by whom it has been accomplished, and a set of Internet web sites that are valuable resources to an interested audience.

This year, using those fundamentals, Helmuthand#8217;s presentation will move several steps closer to how todayand#8217;s space-based sensors collect and filter out relevant climate signatures, and how climate scientists piece together those signatures during longer time spans to make best projections of what is likely to happen given certain assumptions and conditions. Two specific examples will be explored that represent and#8220;qualified successand#8221; and effective and#8220;public influenceand#8221; about negative climate consequences and#8212; ozone hole of Antarctica and rampant deforestation in parts of South America and Africa.

By the conclusion of the program, attendees will have a better understanding of how scientists are studying the earthand#8217;s biosphere and making a difference.

Tickets are $10 for adults. Children and students are free. For tickets or more details visit http://www.squawvalleyinstitute.org or call 530-581-4138.
