John Holdren Quotes

People are seeing the impact of climate change around them in extraordinary patterns of floods and droughts, wildfires, heatwaves and powerful storms.

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.

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

The signs of climate change are visible across the nation, from the drought-stricken fields of Central California to the flooded streets of Michigan. Extreme weather is turning people's lives upside down and costing communities millions of dollars in damaged infrastructure and added health care costs.

For millions of Americans, climate change is no longer just a chart or a graph. It's the smoke on our tongues from massive wildfires. It's the floodwater invading our homes and record-breaking hurricanes and heat waves.

Climate change respects no borders.

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

In particular, Australia, because of its ancient geography, soil profile and distinctive weather patterns, is more adversely affected by climate variability than some other continents.

Climate change is real.

Global climate change has a profound impact on the survival and development of mankind. It is a major challenge facing all countries.

I don't like the term 'global warming,' because it's misleading. It implies something that's mainly about temperature, that's gradual, and that's uniform across the planet. And in fact, temperature is only one of the things that's changing.

Climate change is also clearly a matter of huge interest and concern for the scientific community.

If this ice melts in Greenland it can shut down the Gulf Current.

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

I believe global warming and climate change are real threats to our planet.

Climate change is very real.

Pollution from human activities is changing the Earth's climate. We see the damage that a disrupted climate can do: on our coasts, our farms, forests, mountains, and cities. Those impacts will grow more severe unless we start reducing global warming pollution now.

Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts.

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

My view is that climate changes have happened in the last 80 years, that is, the world has got a little bit warmer, although not as warm as it has been in Medieval times, or the Bronze Age.

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

Climate change is here. We have to learn how to deal with it.

Climate Change is a fact!

The risks brought about by climate change are a major concern. It goes without notice—unless people find out that 12 of the last 13 biggest climatic disorders have occurred in the last 10 years.

Climate change has been going on as long as the planet is here. There will be a little bit of it. We can’t stop it.
