James Hansen Quotes

The effects of climate change are real and must be acted on.

We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.

With a disaster like global warming, it's too late to worry about when it's looming except to figure out how to adapt to it.

The science tells us that if we fail to reduce global warming pollution, global temperatures will rise to dangerous levels and unleash devastating extreme weather events and accelerate destructive sea level rise.

Climate change is a really abstract thing in most of the world.

It seems incontrovertible to me that there is a global warming effect and that it is going to be serious, probably not in the amount of, say, six degrees warming, but it's likely that we'll get two to three degrees warming and that will be serious enough.

Climate change is very real.

Climatologists are all agreed that we'd be lucky to see the end of this century without the world being a totally different place, and being 8 or 9 degrees hotter on average.

Anyone who says there is not a change in weather patterns is denying reality.

I don't think anybody would dispute that we're seeing a warming of the Earth.

Climate change is the Everest of all problems, the thorniest challenge facing humankind.

Global warming isn't a prediction. It is happening.

Climate change is obviously happening and there is obviously a man-made contribution.

All cities do face similar, significant trends in the future... most importantly global warming and climate change.

Climate change is transforming the world in profound ways that continue to evolve.

No challenge is more of a threat to our children than global warming.
