A boat skims through the melting ice in the Ilulissat fjord on August 28, 2008, on the western coast of Greenland. Flying low over the vast, white expanse of Greenland's Ilulissat glacier, one of the biggest and most active in the world, the effects of global warming in the Arctic are painfully visible as the ice melts at an alarming rate. The glacier is the most active in the northern hemisphere, producing 10 percent of Greenland's icebergs, or some 20 million tonnes of ice per day. But the glacier is in bad shape, experts warn.
Climate change has been getting a lot of attention lately. It was blamed for last year's extreme heat and for Super-storm Sandy.
President Obama raised the issue of climate change in his State of the Union address, and California just held its second cap and trade auction for greenhouse gas emission permits.
But what if we're already past the point of no return on climate change? What if a better use of our time and resources is figuring out how to adapt?
That's the question that New York Times environmental writer Andrew Revkin, UCLA climate scientist Alex Hall, and environmental historian Jon Christensen hope to address tonight at an event in Culver City.
