Paul R. Ehrlich Quotes

We're clearly not going to stop global warming at this point. We've already raised the temperature of the planet one degree. We've got another degree in the pipeline from carbon we've already emitted. What we're talking about now is whether we're going to have a difficult, difficult century, or an impossible one.

Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000.

Imagine what our planet would look like with an increase in temperature of two degrees or four degrees, given that at 0.8 degrees we already have serious problems in the world.

We're putting 70 million tonnes of pollution into the atmosphere every day, trapping an enormous amount of extra heat from the sun inside the earth's atmosphere. It's threatening to push the planet past a tipping point beyond which climate change would be difficult to stop

The carbon dioxide concentration in the atmosphere is measured. It's uncontroversial. It's going up. We know that has a tendency to warm the atmosphere and we should be worried about that.

Back in 2005, when I was Christopher Eccleston, we saw one of the largest increases on record, of CO2 in the atmosphere. Unless we keep the rise in global temperature to under 2 degrees, by the time I'm Daniel Radcliffe or wee Jimmy Crankie, I won't be able to save the planet. I won't be here to help you -- well I might, but I'll be that bloke who won Any Dream Will Do.

Our climate is changing. The Earth's climate has, in fact, warmed by 1.1 to 1.6 degrees Fahrenheit since the industrial revolution. People look at this and say: Oh, that is not very much. In fact, it is very much, and it changes the dynamic. It impacts species. It kills some. It diminishes the carbon sink of the ocean. It does a number of things.

Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity.

Probably more than anything else, the place that we really see the effects of the power of even the relatively mild temperature increases so far is in the melting of everything frozen on the planet.

A cumulative change of less than 2°C by the end of this century will do no net harm. It will actually do net good [...] rainfall will increase slightly, growing seasons will lengthen, Greenland's ice cap will melt only very slowly, and so on.

The climate is doing its usual tricks. There's nothing much really happening yet. We were supposed to be halfway toward a frying world now.

Global warming is something that happens to all of us, all at once.

The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.

If you think of the ice caps as the fridge of our planet, if your fridge at home died, the food you eat would go rotten, and you'd starve.

The science linking the increased frequency and severity of extreme weather to the climate crisis has matured tremendously in the last couple of years.

The climate continues to deteriorate.

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.

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.

The fact that the climate is getting warmer doesn't scare me at all. There's no reason why one should be scared.

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.

I would be absolutely astounded if population growth and industrialisation and all the stuff we are pumping into the atmosphere hadn't changed the climatic balance. Of course it has. There is no valid argument for denial.

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

In the Arctic, things are already getting freaky. Temperatures have warmed three times faster than the global average.

Too often, the air conditioners we use to cool down also contribute to climate change - the very force that's fueling extreme heat.

Climate change is the 800-pound gorilla in the living room that the media dances around. But in the scientific community, it's a settled question: 95 percent of scientists believe this is happening with 100 percent confidence temperatures are rising.
