The saddest fact of climate change – and the chief reason we should be concerned about finding a proper response – is that the countries it will hit hardest are already among the poorest and most long-suffering. – Bjorn Lomborg
The mammoth was basically done in by climate change. The last ones survived on Wrangel Island, north of Chukotka, until 3,700 years ago. According to Eveny mythology, mammoths scooped up dirt with their tusks to form the first dry land. – Alex Shoumatoff
It’s the poorer people in tropical zones who will get really hit by climate change – as well as some ecosystems, which nobody wants to see disappear. – Bill Gates
People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change. – Bill Gates
The only thing that will really change global warming in the long run is if we radically increase the speed with which we get alternative technologies to deal with climate change. – Bjorn Lomborg
The U.S. news media have a critical role to play in educating the public about climate change. – Amy Goodman
We need to start by having a conversation about climate change. It would be irresponsible to avoid the issue just because it’s uncomfortable to talk about. – Al Franken
In the U.S. I think there are really two reasons we should pursue energy policy. One is climate change, and the second is this notion that the oil market is cartel-ized by people, some of whom are friendly, some of whom are not, some of whom are in a more ambivalent position to us. – Brad Carson
By the time we see that climate change is really bad, your ability to fix it is extremely limited… The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while. – Bill Gates
Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature. – Alan Lowenthal
If you look at all the serious scientists in the world, there is no big disagreement on the basics of this… it would be absolute lunacy to act as if climate change is not occurring. – Nicholas Stern
The growing evidence of climate change is forcing attention on carbon emissions and their reduction. – Gordon Brown
We cannot compromise with the earth; we cannot compromise with the catastrophe of unchecked climate change, so we must compromise with one another. – Gordon Brown
The damage that climate change is causing and that will get worse if we fail to act goes beyond the hundreds of thousands of lives, homes and businesses lost, ecosystems destroyed, species driven to extinction, infrastructure smashed and people inconvenienced. – David Suzuki
It is our duty as states, citizens, and industry leaders to make the energy transition a reality with the ultimate aim of reconciling two major priorities: to meet ever-increasing demand and to confront the complex issue of climate change. – Christophe de Margerie
I think governments will increasingly be tempted to rely on Silicon Valley to solve problems like obesity or climate change because Silicon Valley runs the information infrastructure through which we consume information. – Evgeny Morozov
There is no question that climate change is happening; the only arguable point is what part humans are playing in it. – David Attenborough
Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil. – Frances Beinecke
Though Africa is not responsible for emitting greenhouse gases, it is suffering the consequences of climate change. – Francois Hollande
We can look back through ice-core data and see over 800,000 years, relationships between carbon dioxide and the temperature of the world. So those people who deny the importance of climate change are just wasting their time. They’re also being diversionary because if we don’t act the risks are enormous. – Nicholas Stern
Solving climate change is a complex topic, but in a single crude brush-stroke, here is the solution: the price of carbon dioxide must be such that people stop burning coal without capture. – David J. C. MacKay
I have often spoken about the importance of intentionality in philanthropy: that it has to stir the soul. This is true whether you are feeding the homeless, mentoring a child or working on climate change. – Charles Bronfman
I’m not as convinced as a lot of people are that man-made climate change is the threat they think it is. – Chris Stewart
Too often, the air conditioners we use to cool down also contribute to climate change – the very force that’s fueling extreme heat. – Frances Beinecke
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. – P. J. O’Rourke
Some people will deny anything that displeases or scares them: unusual pain in their chests, unwanted lumps beneath their skin, or the fact that humans share ancestry with apes are a few examples. Another is climate change. – Michael Specter
The Keystone XL pipeline is a threat to our nation. It would increase pollution and intensify climate change for generations to come. We must raise our voices and demand our leaders reject this dirty scheme. – Frances Beinecke
I’m at one with Ed Miliband in saying that it’s important that people have the right to express their democratic voices and also their deep concerns about climate change because we have a planet in peril. – Douglas Alexander
The bottom line is clear: Climate change is a reality, and it is having a real impact. – Eric Schneiderman
