Chevron wants to begin a billion-dollar construction project at its Richmond refinery after environmentalists sued to stop a similar plan a few years ago. The company points to the environmental impact report and says the new facility will be cleaner and safer, but community advocates worry the plan could increase pollution.
In a report released this week, the Intergovernmental Panel on Climate Change said it will take very ambitious efforts -- a reduction in greenhouse gas emissions by up to 70 percent by 2050 -- to keep climate change at acceptable levels. The dire predictions have some asking whether it's time to think about geo-engineering: an attempt to use large-scale, high-tech methods to cool the planet. These ideas have included launching giant mirrors into space or fertilizing the oceans with iron to stimulate phytoplankton growth.
Climate change is threatening life and livelihood across the planet according to a new report by the Intergovernmental Panel on Climate Change. The latest in a series of reports from the U.N. panel, this is the first time the panel calls for adaptation to climate change and points to ways to prepare for the massive changes coming, including protecting against sea level rise, increasing crop yields, and beefing up disaster response. We'll discuss the report with a few of its authors.
