ENVIRONMENT – “Chasing Ice,” a fascinating and award-winning National Geographic documentary about adventure-scientist documenting changes in the arctic will be presented by the Idaho Conservation League and other local environmental groups on Monday, 7 p.m., at the Panida Theater in Sandpoint.
Read on for details about the making of this 2012 film, and why local groups are bringing the stunning images to the big screen in North Idaho.
ENVIRONMENT – Sustainability expert Gloria Flora will be in Spokane this week to discuss how women worldwide are confronting the challenge of climate change.
The free public lecture titled, “If You Can’t Stand the Heat: Women and the Global Response to Climate Change” at 5:30 p.m., Friday (March 22) in the Wolff Auditorium of Gonzaga University's Jepson Center.
The lecture is part of the Gonzaga Environmental Studies Speaker Series — which recently sponsored Dr. Jane Goodall — and is sponsored by the Gonzaga environmental studies, and women’s and gender studies departments.
Read on for more details about Flora and her quest to keep flora and fauna functioning on earth.
CLIMATE CHANGE — Out of sight, out of mind. Next thing you know, they're extinct.
And it's happening faster than ever to fish species, according to a recent study detailed in a Columbia Basin Bulletin report.
From 1900-2010, freshwater fish species in North America went extinct at a rate 877 times faster than the rate found in the fossil record, while estimates indicate the rate may double between now and 2050, the Bulletin reports.
This new information comes from a U.S. Geological Survey study to be published in the September issue of the journal BioScience.
In the fossil record, one freshwater fish species goes extinct every 3 million years, but North America lost 39 species and 18 subspecies between 1898 and 2006. Based on current trends in threatened and endangered fish species, researchers estimate that an additional 53-86 species of freshwater fish may be extinct by the year 2050.
Since the first assessment of extinct North American freshwater fishes in 1989, the number of extinct fishes increased by 25 percent.
“This study illustrates the value of placing current events into the context of deep geologic time, as rocks preserve an unbiased record of natural rates of processes before human activities began to alter the landscape, the atmosphere, the rivers, and oceans,” said USGS Director Marcia McNutt.
