Bill McKibben Quotes

If there's horrible flooding in Pakistan or a horrible heat wave in Texas, we're no longer able to call it an act of God, or a natural disaster, or something like that, the way we could have through all of human history until 35 or 40 years ago.

In the last two years 24 countries have set new all-time temperature records. We've seen flooding on an epic scale in every continent .

If left unchecked, global change will create violent conflict, torrential storms, shrinking coastlines, and irreversible catastrophe.

With nine degrees of warming, computer models project that Australia will look like a disaster movie. Habitats for most vertebrates will vanish. Water supply to the Murray-Darling Basin will fall by half, severely curtailing food production.

So imagine a world 6 degrees warmer. It's not going to recognize geographical boundaries. It's not going to recognize anything. So agriculture regions today will be wiped out.

Every day, it seems, a new extreme weather catastrophe happens somewhere in America, and the media's all over it, profiling the ordinary folks wiped out by forest fires, droughts, floods, massive sinkholes, tornadoes.

Global warming is the foreboding thunder in the distance. Ocean acidification is the lightning strike in our front yard, right here, right now.

The entire North Polar ice cap is disappearing before our very eyes. It's been the size of the continental United States for the last 3 million years and now 40 percent is gone and the rest of it is going.

Droughts come and go, but this one is so extreme that it will doubtless affect the discussion of climate change.

Here in New York, we are already seeing how climate change contributes to increasingly violent and extreme weather that has cost us dearly, in both damage and in lives.

Climate change is the biggest issue facing our planet. Extreme weather hit every populated continent in 2018, killing, injuring and displacing millions.

In the current scenario of climate change, predictions of extreme weather events are becoming difficult.

Americans are worried about climate change because they can already witness its effects. They see its signature in the drought in California, where record heat has dried the state's fertile soil.

Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.

Our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change. The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year [2011] can each be attributed to climate change. The odds that natural variability created these extremes are minuscule, vanishingly small. To count on those odds would be like quitting your job and playing the lottery every morning to pay the bills.

Humanity is sitting on a time bomb. If the vast majority of the world's scientists are right, we have just ten years to avert a major catastrophe that could send our entire planet's climate system into a tail-spin of epic destruction involving extreme weather, floods, droughts, epidemics and killer heat waves beyond anything we have ever experienced - a catastrophe of our own making.

I sometimes wish we could have, over the next five or ten years, a lot of horrid things happening-you know, like tornadoes in the Midwest and so forth-that would get people very concerned about climate change.

Today we're seeing that climate change is about more than a few unseasonably mild winters or hot summers. It's about the chain of natural catastrophes and devastating weather patterns that global warming is beginning to set off around the world.. the frequency and intensity of which are breaking records thousands of years old.

We have to, in the next ten years, begin to decrease the rate of carbon dioxide emissions and then flatten it out. If that doesn't happen in ten years, we're going to be passing certain tipping points. If the ice sheets begin to disintegrate, what can you do about it? You can't tie a rope around an ice sheet.

What's at risk [in 100 years] if we do not take action, truly is the survival of civilization as we know it... Literally that is the case. We have seen global warming so far of just a little bit less than one degree Celsius and look at what's happened. Superstorm Sandy. Boulder Colorado. All these fires. Hurricane Irene one year before.

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

Our climate is changing. And while the increase in extreme weather we have experienced in New York City and around the world may or may not be the result of it, the risk that it may be - given the devastation it is wreaking - should be enough to compel all elected leaders to take immediate action.

We have at most ten years - not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions... We are near a tipping point, a point of no return, beyond which the built in momentum and feedbacks will carry us to levels of climate change with staggering consequences for humanity and all of the residents of this planet.

A couple degrees warmer would be good for humanity and planet, especially with more plant-fertilizing carbon dioxide in the air. [...] But a couple degrees colder would bring serious adverse consequences for habitats, wildlife, agriculture and humanity."

By 2040, the Sahara will be moving into Europe and Berlin will be as hot as Baghdad. Atlanta will end up a kudzu jungle. Phoenix will become uninhabitable, as will parts of Beijing (desert), Miami (rising seas) and London (floods). Food shortages will drive millions of people north, raising political tensions.
