Elon Musk Quotes

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.

Is the mean temperature of the ground in any way influenced by the presence of heat-absorbing gases in the atmosphere?

The greenhouse effect is something you can observe experimentally - and most people have observed the greenhouse effect themselves, in greenhouses. Yes?

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.

It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up.

Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.

Venus has a runaway greenhouse effect. I kind of want to know what happened there because we're twirling knobs here on Earth without knowing the consequences of it. Mars once had running water. It's bone dry today. Something bad happened there as well.

Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.

Al Gore likes to say that mankind puts 70 million tons of carbon dioxide into the atmosphere every day. What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas-water vapor-into the atmosphere every day and removes about the same amount every day. While this does not 'prove' that global warming is not man-made, it shows that weather systems have by far the greatest control over the Earth's greenhouse effect, which is dominated by water vapor and clouds.

You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on... So it's a fixer-upper of a planet.

Eighty per cent of global warming comes from livestock and deforestation.

There is no doubt that we should take solar radiation into account. We have seen ground temperatures rising since 1975, and it is important to know to what extent that has been caused by the sun or by carbon dioxide.

The society of life on Mars, or the challenge of making Mars more livable, will have significant benefits on our attempts to modify and change in some ways the environment here on Earth.

Global Warming

We now know beyond a doubt that global warming is a reality. And the question we must all answer is, what are we going to do about it?

Climate Change is a fact!

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.

We recognize that greenhouse gas emissions are one of the factors affecting 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 models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.

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.

I'm often asked whether I believe in Global Warming. I now just reply with the question: "Do you believe in Gravity?"

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.

It does not matter whether we burn fossil fuels with malice or with love. As far as the atmosphere is concerned, it is not concerned. It is a collection of gases.
