It Is Not Too Late
One of the world's leading climate scientists, Dr. James Hansen, provides a good general overview of the pitfalls and possibilities in regard to addressing changing climate. He delivers the message that though climate change may be close to a tipping point beyond which cataclysmic change is inevitable, we have not yet crossed this threshold and it is not too late. Even as ecological collapse looms, it is good to hear from the father of global warming concern that there is hope. Of course, this presupposes that unprecedented political will is quickly mobilized to achieve massive reductions in greenhouse gas emissions and energy conservation.
It's not too late
The Earth's climate is nearing, but has not passed, a tipping point beyond which it will be impossible to avoid climate change with far-ranging undesirable consequences. These include not only the loss of the Arctic as we know it, with all that implies for wildlife and indigenous peoples, but losses on a much vaster scale due to rising seas.
