Climate change - for so long an abstract concern for an academic few - is no longer so abstract. Even the Bush administration's Climate Change Science Programme reports 'clear evidence of human influences on the climate system.'
The U.S. has fallen well behind Europe in recognizing climate change and the implications of climate change.
Is there climate change? I live in the shadow of some of the greatest climate change the world has ever seen. It's called the Rocky Mountains. When the glaciers went back.
The water issue is critically related to climate change. People say that carbon is the currency of climate change. Water is the teeth.
It appears that President Obama is making great progress on climate change, he is changing the political climate in the country back to Republican.
One of the biggest obstacles to making a start on climate change is that it has become a cliche before it has even been understood
The trouble with climate change is it's an extraordinarily diverse and complex issue, but for example if the BBC would let me make some of the programmes I'd like to make on climate change, I bet you there would be a change of emphasis.
We need healthy forests if we want to protect our climate. As the climate changes, forests become more vulnerable to insect outbreaks, droughts and wildfires. Simultaneously, when our forests are destroyed, their carbon is released back into the atmo...
Around the world, climate change is an existential threat - but if we harness the opportunities inherent in addressing climate change, we can reap enormous economic benefits.
Maybe climate change is a threat, and maybe climate change has been tarted up by climatologists trolling for research grant cash. It doesn't matter.
Climate change is real. Climate change is being substantially increased by humans and the carbon we put into the atmosphere. And it appears to be speeding up. If science has made any mistakes, science has been underestimating it.
As long as scepticism is based on a sound understanding of science it is invaluable, for that is how science progresses. But poor criticism can lead those who are unfamiliar with the science involved into doubting everything about climate change pred...
Climate change is very real.
We are already experiencing the symptoms of climate change, especially with a hotter and drier climate in southern Australia - the rush to construct desalination plants is an expensive testament to that.
I believe climate change is real - and I believe we have to act to protect the climate as fast as we possibly can.
Geoengineering - the deliberate, large-scale manipulation of the earth's climate to offset global warming - is a nightmare fix for climate change.
Clean air and a healthy climate benefit all of us, but it will take a diverse coalition to step up to the threat posed by unchecked climate change.
Being told about the effects of climate change is an appeal to our reason and to our desire to bring about change. But to see that Africans are the hardest hit by climate change, even though they generate almost no greenhouse gas, is a glaring injust...
Climate change is a controversial subject, right? People will debate whether there is climate change... that's a whole political debate that I don't want to get into. I want to talk about the frequency of extreme weather situations, which is not poli...
We have great international experts within India telling us that the climate is changing, and actions has to be taken, otherwise China and India would be the countries most to suffer from climate change.
I do believe in the Bible as the final word of God. And I do believe that God said the Earth would not be destroyed by a flood. Now, do I believe in climate change? In my trip to Greenland, the answer is yes. The climate is changing.
