A new White House report on climate change has a simple but powerful message: the future is now. In California, the current drought, milder winters, hotter summers and wildfires can all be chalked up to growing levels of greenhouse gases trapped in the atmosphere. Weatherman Bill Martin of KTVU in Oakland was the only California meteorologist invited to the White House this week for scientific briefings and a chat with President Obama. The strategy? Bypass the usual political reporters who cover Washington. We talk with Martin about how this week's report was different from past warnings about climate change.
