Barack Obama Quotes

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

Unless we stop dumping 70 million tons of global warming pollution into the atmosphere every 24 hours, which we are doing right now ... the continued acceleration of this pollution would destroy the future of human civilization.

Science is warning us that if we do not quickly reduce the global warming pollution that is trapping so much of the heat our planet normally radiates back out of the atmosphere, we are in danger of creating a permanent 'carbon summer'.

If there is no cost to be paid for the indiscriminate dumping of pollution into the earth's atmosphere, then it should be a surprise to no one that today we will dump another 70 million tons of global warming pollution into the thin shell of atmosphere surrounding our planet. ... We have to [act] this year, not next year. Mother Nature does not do bailouts.

Climate change is real and humans do contribute to those changes.

We are upsetting the atmosphere upon which all life depends. In the late 80s when I began to take climate change seriously, we referred to global warming as a "slowmotion catastrophe" one we expected to kick in perhaps generations later. Instead, the signs of change have accelerated alarmingly.

Climate change is real and it is caused to a significant extent by human activity.

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.

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.

No country can hide from the dangers of carbon pollution

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.

I'm not a global warming believer. I'm not a global warming denier. I'm a global warming agnostic who believes instinctively that it can't be very good to pump lots of CO2 into the atmosphere but is equally convinced that those who presume to know exactly where that leads are talking through their hats.

The cumulative amount of man-made global pollution that's in the atmosphere now traps as much extra heat energy every day as would be released by 400,000 Hiroshima-class atomic bombs exploding every day. It's a big planet, but that's an awful lot of energy.

I have voted that climate change is happening and it's also caused by man.

The evidence for human-made climate change is overwhelming.

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.

The truth is, as most of us know, that global warming is real and humans are major contributors, mainly because we wastefully burn fossil fuels.

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

Coal is responsible for as much atmospheric carbon dioxide as other fossil fuels combined and it still has far greater reserves. We must stop using it.

My goal is to leave this planet with the biggest carbon footprint I can possibly leave.

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.

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

You may be able to fool the voters, but not the atmosphere.

The biggest drag on global growth in the coming decade will be the impact of energy on the environment.

Clearly there’s going to be an impact. So I’m not disputing that increasing CO2 emissions are in the atmosphere is going to have an impact. It will have a warming impact. It’s an engineering problem and it has engineering solutions.
