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.
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.
It is just human nature to take time to connect the dots, I know that. But I also know that there can be a day of reckoning when you wish you had connected the dots more quickly.
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.
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.
Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.
As many know, the Chinese expression for "crisis" consists of two characters side by side. The first is the symbol for "danger," the second the symbol for "opportunity."
The insistence on complete certainty about the full details of global warming-the most serious threat we have ever faced-is actually an effort to avoid facing the awful, uncomfortable truth: that we must act boldly, decisively, comprehensively, and quickly, even before we know every last detail about the crisis. Those who continue to argue that the appropriate response is merely additional research are simply seeking to camouflage timidity or protect their vested interest in the status quo.
The mountain glaciers in every region of the world are melting, many of them at an accelerated rate, threatening drinking supplies - drinking water supplies and agricultural water supplies. We have these record storms, drought, floods, fires, three deaths (ph) in the American West, climate refugees beginning now, expected to rise to the hundreds of millions unless we take action.
Humanity is sitting on a time bomb. If the vast majority of the world's scientists are right, we have just ten years to avert a major catastrophe that could send our entire planet's climate system into a tail-spin of epic destruction involving extreme weather, floods, droughts, epidemics and killer heat waves beyond anything we have ever experienced - a catastrophe of our own making.
Believe in the power of your own voice. The more noise you make, the more accountability you demand from your leaders, the more our world will change for the better.
The climate crisis is the greatest challenge humanity has ever faced. From not only the warming of the earth with higher global temperatures, but also from strengthening storms and expanding droughts to melting ice and rising seas, the costs of carbon pollution are already being felt by governments, corporations, taxpayers and families around the world. The climate crisis will affect everything that we love and alter the course of our future. Now, more than ever, we must come together to solve this global crisis. We must act decisively, rise to the occasion and solve this monumental challenge.
