We are upsetting the atmosphere upon which all life depends. In the late 80s when I began to take climate change seriously, we referred to global warming as a "slowmotion catastrophe" one we expected to kick in perhaps generations later. Instead, the signs of change have accelerated alarmingly.
Our personal consumer choices have ecological, social, and spiritual consequences. It is time to re-examine some of our deeply held notions that underlie our lifestyles.
Climate change is such a huge issue that it requires strong, concerted, consistent and enduring action by governments.
There is a natural greenhouse effect that contributes to warming. Greenhouse gases trap heat and thus warm the Earth because they prevent a significant portion of infrared radiation from escaping into space.
We don't have time for a meeting of the Flat Earth Society.
There is a sufficiency in the world for man's need but not for man's greed.
We have to face the reality of climate change. It is arguably the biggest threat we are facing today.
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.
I'm no longer sceptical. I no longer have any doubt at all. I think climate change is the major challenge facing the world.
Human use of fossil fuels is altering the chemistry of the atmosphere; oceans are polluted and depleted of fish; 80 per cent of Earth's forests are heavily impacted or gone yet their destruction continues. An estimated 50,000 species are driven to extinction each year. We dump millions of tonnes of chemicals, most untested for their biological effects, and many highly toxic, into air, water and soil. We have created an ecological holocaust. Our very health and survival are at stake, yet we act as if we have plenty of time to respond.
As governor I have seen the tremendous changes over the last few years; the amount of land that we have lost, the trees that we have lost, the homes that we have lost, lives that have been lost, and it is due to a large extent to global warming.
The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists, but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.
Think about this: terrorism, epidemics, poverty, the proliferation of weapons of mass destruction-all challenges that know no borders-the reality is that climate change ranks right up there with every single one of them.
Unless we free ourselves from a dependence on these fossil fuels... we are condemning future generations to global catastrophe
Today we're seeing that climate change is about more than a few unseasonably mild winters or hot summers. It's about the chain of natural catastrophes and devastating weather patterns that global warming is beginning to set off around the world.. the frequency and intensity of which are breaking records thousands of years old.
We consider it vital that the community of nations be drawn together in an orderly, disciplined, rational way to review the history of our global environment, to assess the potential for future climate change, and to develop effective programs.
For the sake of our children and our future, we must do more to combat climate change.
Even as I speak, the very last polar bear may be dying of hunger on account of climate change, on account of us. And I sure miss the polar bears. Their babies are so warm and cuddly and trusting, just like ours.
What we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return
I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while.
Two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves and deal with the underlying causes of global warming.
The impact of climate change is a tremendous risk to the security and well-being of our countries.
This is the new politics. Personal responsibility. Not leaving it to others. I am my planet's keeper.
The earth, our home, is beginning to look more and more like an immense pile of filth. In many parts of the planet, the elderly lament that once beautiful landscapes are now covered with rubbish.
Climate change poses clear, catastrophic threats. We may not agree on the extent, but we certainly can't afford the risk of inaction.
