Sentences with phrase «point than carbon dioxide»

Not exact matches

«The findings showed no mineralogical evidence for abundant liquid water or its by - products, thus pointing to mechanisms other than the flow of water — such as the freeze and thaw of carbon dioxide frost — as being the major drivers of recent gully evolution,» the team explained in the press release.

To put these numbers in perspective, the amount of carbon dioxide the state would need to reduce, to make up for Indian Point's closure, is the equivalent of the annual greenhouse - gas emissions of more than 2.4 million passenger cars.

Researchers from the United Kingdom and Brazil also said the pair of droughts have raised concerns that the forest could be approaching a point where it ceases to be a carbon «sink,» absorbing more carbon dioxide from the atmosphere than it produces, and flips to a carbon source.

The air holds virtually no oxygen but has between a hundred and a thousand times more carbon dioxide than today, a global greenhouse so effective that the waves below may be near boiling point.

From the atmosphere's point of view, growing biomass to burn in a power plant and using the electricity to move a car avoids 10 tons of carbon dioxide emissions per acre, or 108 percent more emission offsets than ethanol.

Scientists expected the 400 ppm mark to be surpassed at an earlier date this year — and, indeed, that point came a full two months earlier than last year — and for this year to see the first monthly carbon dioxide average above 400 ppm.

At the freezing point, carbon dioxide is 30 times more soluble than oxygen and 70 times more soluble than nitrogen.

Of course, a little rain never hurt anyone, but I haven't reached my final point yet which is that a huge number of air conditioners use HFCs, a refrigerant that is far more powerful than carbon dioxide when it comes to contributing to the greenhouse effect.

John Carter August 8, 2014 at 12:58 am chooses to state his position on the greenhouse effect in the following 134 word sentence: «But given the [1] basics of the greenhouse effect, the fact that with just a very small percentage of greenhouse gas molecules in the air this effect keeps the earth about 55 - 60 degrees warmer than it would otherwise be, and the fact that through easily recognizable if [2] inadvertent growing patterns we have at this point probably at least [3] doubled the total collective amount in heat absorption and re-radiation capacity of long lived atmospheric greenhouse gases (nearly doubling total that of the [4] leading one, carbon dioxide, in the modern era), to [5] levels not collectively seen on earth in several million years — levels that well predated the present ice age and extensive earth surface ice conditions — it goes [6] against basic physics and basic geologic science to not be «predisposed» to the idea that this would ultimately impact climate.»

But the truth is that the ocean recirculates that extra load and, at some point, will release some of it back to the atmosphere, where it will keep raising temperatures, even if future carbon dioxide emissions were to be much lower than they are now.»

Their results showed that the forest's ability to store more carbon dioxide than it emitted had weakened over the last few years - to the point where it has now become a net emitter of carbon.

Air bubbles trapped in the ice and chemical clues about atmospheric carbon levels in corals have shown that there is now more carbon dioxide in the air than at any other point in the history of human civilization.

In his point # 6 (Scale of Task), he states: «Scientists describe warming of two degrees Celsius (2C) not as the boundary for dangerous climate change, but as representing a boundary between dangerous and extremely dangerous CLIMATE CHANGE, pointing to a safe boundary as being under 350 parts per million carbon dioxide equivalent (ppm CO2e), more than 120 ppm CO2e below the current level.

-LRB-... besides to point out that «the uncertainty in climate projections associated with the physical climate model is smaller than the uncertainty associated with the models of emission scenarios that are used to project carbon dioxide emissions»)
