Sentences with phrase «gtc scenario»

In contrast, the 1000 GtC scenario, although nominally designed to yield a fast - feedback climate response of ∼ 2 °C, would yield a larger eventual warming because of slow feedbacks, probably at least 3 °C.

Global temperature in 2100 would be close to 1 °C in the 500 GtC scenario, and it is less than 1 °C if 100 GtC uptake of carbon by the biosphere and soil is achieved via improved agricultural and forestry practices (Fig. 9).

Global temperature in 2100 would be close to 1 °C in the 500 GtC scenario, and it is less than 1 °C if 100 GtC uptake of carbon by the biosphere and soil is achieved via improved agricultural and forestry practices (Fig. 9).

If all of the currently attainable carbon resources [estimated to be between 8500 and 13.600 GtC (4)-RSB- were burned, the Antarctic Ice Sheet would lose most of its mass, raising global sea level by more than 50 m. For the 125 GtC as well as the 500, 800, 2500, and 5000 GtC scenarios, the ice - covered area is depicted in white (ice - free bedrock in brown).

Not exact matches

«One of the proposed scenarios,» comments Romano Corradi, director of the GTC and another of the authors «is the presence of a component in the gas which is different from that which we normally find, poor in hydrogen and rich in heavier elements such as oxygen and carbon.

The CDR potential and possible environmental side effects are estimated for various COA deployment scenarios, assuming olivine as the alkalinity source in ice ‐ free coastal waters (about 8.6 % of the global ocean's surface area), with dissolution rates being a function of grain size, ambient seawater temperature, and pH. Our results indicate that for a large ‐ enough olivine deployment of small ‐ enough grain sizes (10 µm), atmospheric CO2 could be reduced by more than 800 GtC by the year 2100.

In contrast, 2 °C scenarios have total emissions of the order of 1000 GtC.

Cumulative fossil fuel emissions in this scenario are ∼ 129 GtC from 2013 to 2050, with an additional 14 GtC by 2100.

The ecological and environmental implications of scenarios with carbon emissions of 1000 GtC or greater, as discussed below, would be profound and should influence considerations of appropriate energy strategies.

With the stable climate of the ∼ 1 °C scenario it is plausible that major efforts in reforestation and improved agricultural practices [15], [173], [175]--[177], with appropriate support provided to developing countries, could take up an amount of carbon comparable to the 100 GtC in our ∼ 1 °C scenario.

Now let us compare the 1 °C (500 GtC fossil fuel emissions) and the 2 °C (1000 GtC fossil fuel emissions) scenarios.

So the fact that 545 GtC are reached too late doesn't even refer to the usual climate model scenarios.

How Antarctic ice would be affected by different emissions scenarios (GTC = gigatons of carbon).

Other marine - based drainage systems become unstable under higher emission scenarios, until most of the marine ice is eventually lost to the self - reinforcing feedback after about 2500 GtC of cumulative carbon release

Compared to the existing IPCC models, terrestrial carbon cycle processes could provide an additional net feedback of 400 GtC or more over this century following the RCP8.5 scenario.

Cumulative fossil fuel emissions in this scenario are ∼ 129 GtC from 2013 to 2050, with an additional 14 GtC by 2100.

Our reforestation scenarios assume that today's net deforestation rate (∼ 1 GtC / year; see [54]-RRB- will stay constant until 2020, then linearly decrease to zero by 2030, followed by sinusoidal 100 GtC biospheric carbon storage over 2031 — 2080.

They note that their results are consistent with those of M2009, as the A2009 scenarios that yield 2 °C warming have 400 — 500 GtC emissions during 2000 — 2049; M2009 find 393 GtC emissions for 2 °C warming, but M2009 included a net warming effect of non-CO2 forcings, while A2009 neglected non-CO2 forcings.

With the stable climate of the ∼ 1 °C scenario it is plausible that major efforts in reforestation and improved agricultural practices [15], [173], [175]--[177], with appropriate support provided to developing countries, could take up an amount of carbon comparable to the 100 GtC in our ∼ 1 °C scenario.

With the stable climate of the ~ 1 °C scenario it is plausible that major efforts in reforestation and improved agricultural practices, with appropriate support provided to developing countries, could take up an amount of carbon comparable to the 100 GtC in our ~ 1 °C scenario.

For example, the comparison of the A1B and B2 marker scenarios indicates that they have similar emissions of about 13.5 and 13.7 GtC by 2100, respectively.

We therefore examine the human health benefits of increasing 21st - century CO2 reductions by 180 GtC, an amount that would shift a «standard» 2 °C scenario to 1.5 °C or could achieve 2 °C without negative emissions.
