We are Christian and Jewish and Muslim and Hindu and none of the above. We are gay and straight. We are black, brown, white, and innumerable combinations. We are young and old, female and male, with and without disabilities, urban and rural, and liberal and conservative. Every one of us is an equal American.

When I was first elected to the Senate, I was fortunate to be appointed to the Intelligence Committee. There, I saw up close the dedication and commitment of the men and women of our intelligence agencies.

Whatever the motivation of the 'Wall Street Journal' and other right-wing publications, it is clearly long past time for the climate denial scheme to come in from the talk shows and the blogosphere and have to face the kind of an audience that a civil RICO investigation could provide.

When counting on learning from innovation, there are great successes but also failures. The Wright Brothers invented the aircraft and started an amazing process of innovation, where we now have planes that carry 500 passengers. Along the way there were some silly looking vehicles that crashed early on.

The global climate is a complex interactive system, with all kinds of nonlinear feedback loops.

In 2007, I received a National Geographic Expeditions Council grant to go around the top of the world and talk to Arctic people about how they've been impacted by climate change.

It really gets on my goat that people keep quoting Dorothea Mackellar's 'My Country' as proof that there is no such thing as climate change. A poem written more than 100 years ago by a homesick 19 year old versus an ever-increasing body of refereed scientific thought... hmm, hard to know which way to jump, really.
