Bill Nye Quotes

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 best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.

Whether the process proves to be Kyoto or something else, let's acknowledge the urgency of global warming.

Global warming and climate change is a big problem. It requires a big solution.

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.

If we're concerned about climate change as a country, we should have policies that make sure our great-grandchildren have a planet that's healthy and strong.

The fight against global warming is a humanitarian issue - how the planet can be preserved - and it is also an issue of considerable economic importance, of what we call green growth.

I agree with the overwhelming majority of scientists who recognize that climate change is real, and it's essential that our country honors its commitment to work with the rest of the world to cut carbon pollution and address this crisis together.

We need to take urgent action on climate change.

The truth is that we're at a critical juncture in the history of our species and if we don't act soon, we could inhabit a world we don't recognize anymore. But the most important truth is that we are capable of stopping climate change before the worst of its consequences are locked in. The solutions exist - all we need is the will to do something about it.

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 enough of us stop looking away and decide that climate change is a crisis worthy of Marshall Plan levels of response, then it will become one.

I'm about to embark on what may be as important as an initiative as anything I do as President, trying to nudge the world in the direction of doing something serious about climate change.

The problem [of climat changing] is only getting worse - that to me underscores that we need a transformative solution.

If there is no cost to be paid for the indiscriminate dumping of pollution into the earth's atmosphere, then it should be a surprise to no one that today we will dump another 70 million tons of global warming pollution into the thin shell of atmosphere surrounding our planet. ... We have to [act] this year, not next year. Mother Nature does not do bailouts.

China and India will take the global leadership on climate change: they are suffering for it.

When it comes to dealing with the world's climate and energy challenges, I have a simple rule: change America, change the world.

What do we do about climate change bearing down upon us?

You will not solve global climate change by hitting the delete button.

We run enormous risks and we know what kind of reductions of greenhouse gases are necessary to drastically reduce risks. Reducing emissions by half by 2050 is roughly in the right ballpark. It would bring us below 550 ppm.

Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.

If each one of us does our bit, we will be helping to keep global warming from harming our countries.

There's no shortage of Democrats who are at least as committed as Schwarzenegger to reducing greenhouse gases.

I am now certain that we have no alternative but to reduce urgently the levels of carbon that we are still pumping into the atmosphere as though tomorrow simply didn't matter. If we don't act collectively and individually, our children and their children will reap a whirlwind which will obliterate their civilisation.

I think that once people understand the great risks that climate change poses, they will naturally want to choose products and services that cause little or no emissions of greenhouse gases, which means 'low-carbon consumption.' This will apply across the board, including electricity, heating, transport and food.
