Here's the truth: even if countries like the United States curb our emissions, if growing countries like India - with soaring energy needs - don't also embrace cleaner fuels, then we don't stand a chance against climate change.
There are folks who will equivocate. They'll say, 'You know, I'm not a scientist.' Well, I'm not either. But the best scientists in the world know that climate change is happening.
You are part of the first generation of officers to begin your service in a world where the effects of climate change are so clearly upon us. Climate change will shape how every one of our services plan, operate, train, equip, and protect their infrastructure, today and for the long-term.
Young people: I understand this is important to you, but as you be thinking about climate change, the economy and jobs, war and peace, maybe way at the bottom you should be thinking about marijuana.
It means joining with allies to deploy renewable energy technologies -- both at home and around the world -- to confront the very real and present danger of potentially irreversible climate change.
Many scales of climate change are in fact natural, from the slow tectonic scale, to the fast changes embedded within glacial and interglacial times, to the even more dramatic changes that characterize a switch from glacial to interglacial. So why worry about global warming, which is just one more scale of climate change? The problem is that global warming is essentially off the scale of normal in two ways: the rate at which this climate change is taking place, and how different the "new" climate is compared to what came before.
I don't feel passionately about politics, i'm not a political person. Is it easy for me to get fired up about someone's position on climate change? No, it's not. On most of these issues, I can see both sides.
You can't tackle climate change until you tackle poverty.
Climate change has taken on political dimensions. That's odd because I don't see people choosing sides over E=Mc2 or other fundamental facts of science.
This is an opportunity, I believe, for the Port and all of us to make a bold statement about how oil companies contribute to climate change, oil spills and other environmental disasters and reject this short-term lease.
What is the environmental policy of the Republican Party? When I ask that question, I get a blank stare, if I'm president of the United States, we're going to address climate change and CO2 emissions in a business-friendly way.
Can we remain indifferent before the problems associated with such realities as climate change?
Climate change disasters will displace more and more. Those who are most exposed are the poorest.
Increasingly gang violence and organized crime, together with climate change-driven natural disasters, are displacing more people as wars are fewer on the continent and political violence has decreased considerably, the NRC has decided to treat this as a humanitarian crisis.
Climate change is the greatest threat of our time.
I believe it's time for direct action on climate change, standing together as ordinary Australians to take control of our shared future.
One of the drivers of displacement and potential conflict over the next 10 to 20 years will be climate (change) - resource scarcity, climate change is going to compound the cocktail that's driving war and displacement.
The bottom billion people don't contribute at all to climate change - maybe 1 percent of emissions, they could double or triple their emissions and the climate would not be destabilised.
The poorest people in the world (particularly in low-lying areas) will suffer the most if we do not take action on climate change... that calls for any tactic that might call attention to the problem.
Twice I have testified in congress that unbiased funding on the subject of the causes of warming would be much closer to a reality if 50% of that money was devoted to finding natural reasons for climate change.
... For nearly a decade now, there has been no global warming. Even though atmospheric CO2 has continued to accumulate - up about 4 percent in the last 10 years - the global mean temperature has remained flat. That should raise obvious questions about CO2 being the cause of climate change.
If the choice is between cooking alive and wasting money unnecessarily I would rather waste some money, because long before we cook we are going to kill each other if we don't deal with climate change.
I think the people running climate change denial campaigns are sociopaths.

We have got to encourage other nations also to come along with us with the impacts of climate change, what we can do about that.
