We are running out of time, we must have a planetary solution to a planetary crisis.

During my service in the United States Congress, I took the initiative in creating the Internet.

Science is warning us that if we do not quickly reduce the global warming pollution that is trapping so much of the heat our planet normally radiates back out of the atmosphere, we are in danger of creating a permanent 'carbon summer'.

Every nation has a moral obligation to safeguard the future.

The consensus is clear. We need an immediate and determined shift to a clean, renewable economy. The continued mass burning of fossil fuels is inconsistent with a healthy, prosperous future for our civilization.

We are close to a time when all of humankind will envision a global agenda that encompasses a kind of Global Marshall Plan to address the causes of poverty and suffering and environmental destruction all over the earth.
