Over the last week or so, I have been blogging about the impacts of climate change on several of our BioGems.  From  the tundra of America's Arctic in Alaska to the tropics of Costa Rica, all of our BioGems are at risk not only from short-sighted schemes, but also from higher temperatures, shifting weather patterns, and altered habitats.  We have been urging our more than 600,000 BioGem Defenders and other citizens to join NRDC and 350.org in taking action on October 24th to pressure politicians worldwide to take decisive action to curb emissions of carbon dioxide which have already concentrated in the atmosphere at more than 350 ppm - which scientists say is the safe upper limit. There are plans for more than 4500 events in 181 countries.     

Here are photos of my colleagues in our offices across the United States taking a stand for 350 and the protection of our ultimate biological gem - the Earth:
