David Tennant Quotes

Every footstep we take, every action has a consequence. We breathe in weather, but we breathe out CO2. We're responsible for weather and for climate.

What do we do about climate change bearing down upon us?

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.

We are on track for a 3.5 deg C rise by 2040 (i.e. 4.2 deg C relative to pre-industrial)... When I look at this data, the trend is perfectly in line with a temperature increase of 6 degrees Celsius, which would have devastating consequences for the planet. We have 5 years to change the energy system, or have it changed

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.

CO2 is the exhaling breath of our civilization, literally... Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past.

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

The pace of global warming is accelerating and the scale of the impact is devastating. The time for action is limited - we are approaching a tipping point beyond which the opportunity to reverse the damage of CO2 emissions will disappear.

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

Global warming and climate change is a big problem. It requires a big solution.

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.

Every day, we're learning about what's happened with global warming and what's happening all around the world, and our employees and our customers are really feeling that it's time to step up and make a difference.

On this 50th Earth Day, we face a crisis unknown to those who gathered on the first Earth Day - the climate crisis.

We need to take urgent action on climate change.

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

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.

Humanity is sitting on a time bomb. If the vast majority of the world's scientists are right, we have just ten years to avert a major catastrophe that could send our entire planet's climate system into a tail-spin of epic destruction involving extreme weather, floods, droughts, epidemics and killer heat waves beyond anything we have ever experienced - a catastrophe of our own making.

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.

I’ve starred in a lot of science fiction movies and, let me tell you something, climate change is not science fiction, this is a battle in the real world, it is impacting us right now.

The hard truth is carbon pollution has built up in our atmosphere for decades now. And even if we Americans do our part, the planet will slowly keep warming for some time to come.

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.

If we did not take action to solve this crisis, it could indeed threaten the future of human civilization. That sounds shrill. It sounds hard to accept. I believe it's deadly accurate. But again, we can solve it.

The science [of global warming] is beyond dispute... Delay is no longer an option. Denial is no longer an acceptable response
