Sentences with phrase «get changes in carbon dioxide»

And we don't have to go back all that far to get changes in carbon dioxide in the atmosphere and quite unknowable albedo effects.

Not exact matches

Coral is already threatened by insidious change in sea water chemistry as ever more carbonic acid — from dissolved atmospheric carbon dioxide, the product of the combustion of fossil fuels — gets into the sea.

The next three climate ads misstate the science of climate change, incorrectly asserting rainfall and droughts are getting worse, that there has been no pause in rising temperatures, and suggesting carbon dioxide has historically caused climate change when the fact is warming has preceded rising carbon - dioxide levels in the past.

We don't get any closer to science by denying the significant possibility that we are causing significantly adverse changes in climate than we do by the ridiculous assertion that we understand the chaotic complexity of climate well enough to say with certainty how many parts per millions of carbon dioxide in the atmosphere will lead to how many degrees of global warming.

From the book «The Moral Case for Fossil Fuels»: «In 1998, Bill McKibben endorsed a scenario of outlawing 60 percent of present fossil fuel use to slow catastrophic climate change, even though that would mean, in his words, that «each human being would get to produce 1.69 metric tons of carbon dioxide annually — which would allow you to drive an average American car nine miles a daIn 1998, Bill McKibben endorsed a scenario of outlawing 60 percent of present fossil fuel use to slow catastrophic climate change, even though that would mean, in his words, that «each human being would get to produce 1.69 metric tons of carbon dioxide annually — which would allow you to drive an average American car nine miles a dain his words, that «each human being would get to produce 1.69 metric tons of carbon dioxide annually — which would allow you to drive an average American car nine miles a day.

Climate scientists know that the planet is warming, and dangerously, as a consequence of ever higher carbon dioxide levels in the atmosphere thanks to changes humans have made to the planet's atmospheric chemistry — and they know it can get worse.

When they look at climate changes in the distant past (paleoclimate), and at simulations from complex climate models, they get about the same result: if the amount of carbon dioxide in the atmosphere doubles, temperatures will rise between 2 °C and 4.5 °C, most likely 3 °C.

Efficiency is very important in the case of fossil fuel power stations because fossil fuels are a finite resource — once we use them they are gone — and when burned they produce carbon dioxide and other substances that kill people and cause climate change and ocean acidification; so it is very important to get as much electricity as we possibly can per tonne of fossil fuel.

more carbon dioxide in the lower atmosphere means more little «point sources» for more absorbed EM in the infrared part of the spectrum, (infrared that re-radiated from the earth's surface after sunlight hit it and got absorbed); and since point sources radiate in a spherical pattern, that means more «back radiation» to earth, on balance... and this changes the «standing pattern» of energy flow in and out of the earth system, creating a time differential, so it starts to re-adjust...

The good news is (at least from the perspective of science) that the role of carbon dioxide in climate change is very well established — at the theoretical level in terms of quantum physics, at the experimental level in terms of the study of the absorbtion and re-emission of radiation by carbon dioxide, at the numerical level (when equations get a little too complicated — but a good approximation can result from intensive computation by means of our fairly advanced computers), in terms of historical trends going back more than 500,000 years — and countless studies.
