Barack Obama Quotes

The biggest drag on global growth in the coming decade will be the impact of energy on the environment.

The only way we can hope to combat climate change, protect our precious land and water, and prevent future extreme weather disasters is to cut the carbon pollution that’s warming our planet, and replace dirty energy sources with clean, renewable sources.

Most reputable scientists agree that climate change is real and that the effects are likely to be bad. But nobody can say for sure exactly what 'bad' means. The safest and most equitable way out of this horrific mess is simple: cut fossil-fuel emissions.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

The second thing is, if you want to do something about global warming, you have to think much more long-term. There is something wrong with saying we should start using renewables now, while they are still incredibly expensive.

When you boil down the real facts and statistics of what carbon dioxide is doing to this planet... to not feel like you have to do something... I don't think you're human.

If 98 doctors say my son is ill and needs medication and two say, “No, he doesn’t, he is fine,’ I will go with the 98. It’s common sense-the same with global warming. We go with the majority, the large majority...The key thing now is that since we know this industrial age has created it, let’s get our act together and do everything we can to roll it back.

There is only one possible route of action, Greenhouse gases have to be radically reduced and it has to happen worldwide. Until now, the US has kept its eyes shut to this emergency. Americans make up a mere 4 percent of the population, but are responsible for close to a quarter of emissions.

Global warming' is just the latest in a long line of hysterical crusades to which we seem to be increasingly susceptible.

World leaders need to realize that the cost of transforming the global energy system is far less than coping with the consequences of burning the planet's remaining fossil fuels.

Clinton understands that climate change is real, is caused by human activity and is one of the great environmental crises facing our planet. She knows that we must transform our energy system away from fossil fuels and move aggressively to energy efficiency and sustainable energy.

I think global warming is the gravest threat. With global warming, it's the product of a war between old energy - between the carbon cronies, who, by the way, could not stay in business in a true free market capitalism.

And by the way, the United States is the biggest cause in global warming pollution. And we're doing the least about it. I find that personally embarrassing.

While the leading environmental alarmists burn fossil fuels like they're going out of style, the United States under President Trump has led the world in reducing carbon emissions.

Many are outspoken about the climate crisis, but conveniently ignore the fact that support for fossil fuels is not just incompatible with curbing emissions but dangerously counterproductive.

Twenty-five years ago people could be excused for not knowing much, or doing much, about climate change. Today we have no excuse. No more can it be dismissed as science fiction; we are already feeling the effects.

I believe, along with Pope Francis and almost all scientists, that climate change is threatening this planet in horrendous ways, and that we have to be aggressive in transforming our energy system away from fossil fuel and defeat the Keystone Pipeline.

If what the science tells us about climate change is correct, then unabated it will result in catastrophic consequences for our world.

We are on track for a 3.5 deg C rise by 2040 (i.e. 4.2 deg C relative to pre-industrial)... When I look at this data, the trend is perfectly in line with a temperature increase of 6 degrees Celsius, which would have devastating consequences for the planet. We have 5 years to change the energy system, or have it changed

...climate change is accelerating. It threatens our well being, our security, and our economic development. It will lead to uncontrollable risks and dramatic damage if we do not take resolute countermeasures.

But no matter how big the effort to push a propaganda line might be, climate change is bigger. This, undoubtedly and regrettably, is the biggest immediate long-term environmental challenge we face. A failure to concretely come to some policy outcome on climate change has not only a negative environmental impact but also social and economic consequences for us.

Climate change is real, caused by human activity and already devastating our nation and planet. The United States must lead the world in combating climate change and transforming our energy system away from fossil fuels and toward energy efficiency and sustainability.

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.

The U.S. has historically been the world's largest contributor to climate change.

The evidence for human-made climate change is overwhelming.
