“I’m probably the wrong person to ask. My partner in much of this work [climate movement], who really came up with the divestment campaign with me, Naomi Klein, I think has written powerfully about this.”

We use the web to help people organize in the flesh, and then we take the images of those events and put them back on the web to make them add up to more than the sum of their parts.

A voluntary simplification of life-styles is not beyond our abilities, but it is probably outside our desires.

We can either save the planet from catastrophic warming, or protect fossil fuel CEOs. Not both. Do the math(s)

In fact, corporations are the infants of our society – they know very little except how to grow (though they’re very good at that), and they howl when you set limits. Socializing them is the work of politics. It’s about time we took it up again.

Certainly, packets of sea ice, in say the Arctic, which have failed to fully reform in the last couple of years.

In the States we’ve had by far the largest demonstrations in the last few years. The largest civil disobedience actions about anything in US history in the last 30 years have all been centred around the climate.

We’re not at the point of trying to stop global warming; it’s too late for that. We’re trying to keep it from becoming a complete and utter calamity

It’s off the charts – and if you don’t believe the scientists, ask the insurance industry, the people we pay to analyze risk in our society.

You can have a healthy fossil-fuel balance sheet, or a relatively healthy planet

If one wanted to stigmaitise, that’s how one would do it – lots and lots of people saying “we’re severing our ties”.

Probably nothing that we have ever managed to do quite equals the basic undermining of the physical stability of the planet on which most of the world’s poor people depend.

“Science,” of course, replaced “God” as a guiding concept for many people after Darwin. Or, really, the two were rolled up into a sticky ball. To some degree this was mindless worship of a miracle future, the pursuit of which has landed us in the fix we now inhabit.

Without a movement pressing for change, there’s little hope. We’ve got to work the political system to make this happen fast. The physics and chemistry are daunting. The resources on the other side are very large.

It is unbelievably sad and ironic that the first victims of global warming are almost all going to come from places that are producing virtually none of the problem.

We’d won the argument 15 years before, we were just losing the fight. And so it became clear to some of us that we would need to organise to fight, that we weren’t going to win.

I think we need to go straight at the fossil fuel industry.

What we do to animals directly impacts everything, because we are all connected. It disrupts the food chain, it funds terrorism (ivory), it changes our climate, our oceans, it starts wars.

Diplomats are useful only in fair weather. As soon as it rains they drown in every drop.

We should be treating, I think, the whole issue of climate change and global warming with a far greater degree of priority than I think is happening now.

One of the main reasons for the conflict in Syria, and the terrorism that it’s spawned, is climate change and drought.

I think we’re going to find, with climate change and everything else, things like global warming and goodness knows what else and the cost of fuel for a start, that things are going to become very complicated.

Climate change should be seen as the greatest challenge to face man and treated as a much bigger priority in the United Kingdom.

It is baffling, I must say, that in our modern world we have such blind trust in science and technology that we all accept what science tells us about everything – until, that is, it comes to climate science.

Scientists with access to data from Navy submarines traversing underneath the North polar ice cap have warned that there is now a 75 percent chance that within five years the entire ice cap will completely disappear during the summer months.
