Sentences with phrase «doubling of atmospheric carbon dioxide»

An international team examining the impact of ocean acidification on coral has found that a key reef - building coral can, over a relatively short period of time, acclimate to a doubling of atmospheric carbon dioxide levels.

Indeed, the team estimates that this cooling effect could reduce by two - thirds the predicted increase in global temperatures initiated by a doubling of atmospheric carbon dioxide.

The second simulation overlaid that same weather data with a «pseudo global warming» technique using an accepted scenario that assumes a 2 - to 3 - degree increase in average temperature, and a doubling of atmospheric carbon dioxide.

Doubling of atmospheric carbon dioxide would heat the world more than many climate models suggest

Earth's climate may warm considerably more than expected in response to a doubling of atmospheric carbon dioxide, a new study hints.

These questions, percolating for a few months in the blogosphere, came to a head with a recent article in The Economist questioning climate sensitivity — the amount of surface warming expected for a doubling of atmospheric carbon dioxide levels.

The study projects that a doubling of atmospheric carbon dioxide (CO2) concentrations over pre-industrial levels will increase global temperatures by between 1.2 °C and 2.9 °C, with 1.9 °C being the most likely outcome.

Parkinson's study, which was published in 1979, found that a doubling of atmospheric carbon dioxide from preindustrial levels would cause the Arctic to become ice - free in late summer months, probably by the middle of the 21st century.

We know the planet will warm between about 1.5 and 4.5 °C in response to the increased greenhouse effect from a doubling of atmospheric carbon dioxide (the «climate sensitivity»).

In their model, the researchers were able to tease out the impacts of one factor at a time, which allowed them to investigate and quantify the monsoon response to the doubling of atmospheric carbon dioxide, increased temperatures and other individual changes.

Unfortunately it finds that clouds will act to amplify global warming, suggesting that the planet will warm at least 3 °C in response to a doubling of atmospheric carbon dioxide, which also suggests at least 4 °C global surface warming by 2100 if we continue with business as usual policies.

The second simulation overlaid that same weather data with a «pseudo global warming» technique using an accepted scenario that assumes a 2 - to 3 - degree increase in average temperature, and a doubling of atmospheric carbon dioxide.

Our DOE Comment focuses entirely on the new science concerning the equilibrium climate sensitivity, that is, how much the earth's average surface temperature will increase from a doubling of the atmospheric carbon dioxide content.

They range from a relatively trivial impact — less than one degree Celsius warming from a doubling of atmospheric carbon dioxide — to more than five degrees.

Positive feedback means runaway warming «One of the oft - cited predictions of potential warming is that a doubling of atmospheric carbon dioxide levels from pre-industrial levels — from 280 to 560 parts per million — would alone cause average global temperature to increase by about 1.2 °C.

Climate Sensitivity: The amount the earth will warm with a doubling of atmospheric carbon dioxide (CO2) has been a major issue for years.

So, multiply 0.49 °C / W / M2 by 3.7 W / m2 and you get, according to IPCC's previous numbers, that a doubling of the atmospheric carbon dioxide concentration produces a global temperature rise of roughly about 1.8 °C (at the time of doubling, i.e., in a transient sense).

This value is 20 percent lower than the value calculated with the IPCC AR4 numbers, and leads to a 1.44 °C temperature rise at the time of a doubling of atmospheric carbon dioxide, a weenie.05 °C / decade between now and when (if?)

We have two new entries to the long (and growing) list of papers appearing the in recent scientific literature that argue that the earth's climate sensitivity — the ultimate rise in the earth's average surface temperature from a doubling of the atmospheric carbon dioxide content — is close to 2 °C, or near the low end of the range of possible values presented by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

Regarding the sensitivity of the climate to the increased greenhouse effect, Dessler pointed out that the 2014 IPCC report matched the 2001, 1995, and 1990 reports, estimating an eventual global surface warming of 1.5 — 4.5 °C in response to a doubling of atmospheric carbon dioxide.

Studies show that a doubling of atmospheric carbon dioxide is likely to reduce coral calcification more than 30 percent.

A key example of this balancing process concerns the best value of what is known as the climate sensitivity, that is the increase in global average temperature associated with a doubling of atmospheric carbon dioxide that, unless severe mitigating action is taken, is likely to occur during the second half of the 21st century.

In his book Spencer contends that short - term fluctuations in the energy balance and surface temperature are consistent with a low climate sensitivity: «A careful examination of the satellite data suggests that manmade warming due to a doubling of atmospheric carbon dioxide could be less than 1ºC — possibly much less.»
