John Holdren Climate Quotations

My understanding is that Exxon, in particular, did fund a variety of small think tanks to generate what amounts to propaganda against understanding of what climate change was doing, the human role in causing it.

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

Issues of energy, climate change, nuclear arms control and non-proliferation are all big deals. These are problems that we have to get right globally, not just nationally, and there are big benefits in cooperating, in terms of sharing costs, in terms of sharing risks, in terms of propagating the best answers.

The whole climate is changing: the winds, the ocean currents, the storm patterns, snow packs, snowmelt, flooding, droughts. Temperature is just a bit of it.

Any objective look at what science has to say about climate change ought to be sufficient to persuade reasonable people that the climate is changing and that humans are responsible for a substantial part of that - and that these changes are doing harm and will continue to do more harm unless we start to reduce our emissions.
