Here is the truth: The Earth is round; Saddam Hussein did not attack us on 9/11; Elvis is dead; Obama was born in the United States; and the climate crisis is real.
Civil disobedience has an honourable history, and when the urgency and moral clarity cross a certain threshold, then I think that civil disobedience is quite understandable, and it has a role to play.
The entire North Polar ice cap is disappearing before our very eyes. It's been the size of the continental United States for the last 3 million years and now 40 percent is gone and the rest of it is going.
We can believe in the future and work to achieve it and preserve it, or we can whirl blindly on, behaving as if one day there will be no children to inherit our legacy. The choice is ours; the earth is in balance.
Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.
The debate's over. The people who dispute the international consensus on global warming are in the same category now with the people who think the moon landing was staged on a movie lot in Arizona.
The Himalayan Glaciers on the Tibetan Plateau have been among the most affected by global warming. The Himalayas...provide more than half of the drinking water for 40% of the world's population...Within the next half-century, that 40% of the world's people may well face a very serious drinking water shortage, unless the world acts boldly and quickly to mitigate global warming.
Distributed intelligence is the key to the advancement of human civilization. Dictatorships, communist countries, monarchies in the past all eventually collapsed because of their inefficiency in moving information.
The misconception that there is serious disagreement among scientists about global warming is actually an illusion that has been deliberately fostered by a relatively small but extremely well-funded cadre of special interests, including Exxon Mobil and a few other oil, coal, and utilities companies. These companies want to prevent any new policies that would interfere with their current business plans that rely on the massive unrestrained dumping of global warming pollution into the Earth's atmosphere every hour of every day.
Scientists with access to data from Navy submarines traversing underneath the North polar ice cap have warned that there is now a 75 percent chance that within five years the entire ice cap will completely disappear during the summer months.
