Buzz Aldrin Quotes

When you have energy companies like Shell and British Petroleum, both of which are perhaps represented in this room, saying there is a problem with excess carbon dioxide emission, I think we ought to listen.

Humans have obviously contributed a great deal of carbon to the atmosphere. So we are warming the planet up.

There is a majority of scientists that say that global carbon emissions by humans causes some changes in the climate.

We recognize that greenhouse gas emissions are one of the factors affecting climate change.

Climate change is real. Climate change is being substantially increased by humans and the carbon we put into the atmosphere. And it appears to be speeding up. If science has made any mistakes, science has been underestimating it.

Carbon dioxide isn't the only greenhouse gas out there. Other substances, such as water vapor and nitrous oxide, also trap heat to varying degrees.

Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.

Humans are contributing to additional carbon dioxide in the atmosphere.

Burning fossil fuels emits carbon dioxide. And carbon dioxide is a greenhouse gas that traps heat in the atmosphere. There is no debate about that. The link is as certain as the link between smoking and cancer.

We must act to reduce the increasingly dangerous and destructive levels of carbon pollution that account for practically all of global climate change.

I have not been one who believed in the global warming. But I tell you, they are making a convert out of me as these blistering summers. They have broken heat records in a number of cities already this year and broken all-time records and it is getting hotter and the ice caps are melting and there is a build up of carbon dioxide in the air. We really need to address the burning of fossil fuels.

The U.S. has historically been the world's largest contributor to climate change.

Chinese emissions are a problem not just for its own people but also for the world. It has now overtaken the U.S. as the biggest carbon emitter; most of the coal that is burned anywhere on Earth is burned in China.

I don't think global warming is to do with us, I think it's a natural circle. I don't think a few Ferraris make that much difference.

Climate change is real.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other.

When it comes to global warming, coal is the gorilla in the room.

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 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 a really abstract thing in most of the world.

You see, the Greenhouse Effect is a direct result of burning fossil or old carbon fuels.

CO2 is not a pollutant in any normal definition of the term.
