Sentences with phrase «peak emissions within»

Yet with the need to peak emissions within 10 years, gas turbines will be unacceptably high in emissions in the short run, unless CCS is part of their utilization.

Not exact matches

«Carbon reductions won't hinder Chinese growth: Professor sees coal use peaking within next decade, emissions dropping soon after.»

Meanwhile, leaders in China, analysts there say, are seriously debating a 2025 peak year for greenhouse gas emissions as well as an absolute cap on coal within the next five years.

The report concludes that global emissions must peak then decline rapidly within the next five to ten years for the world to have a reasonable chance of avoiding the very worst impacts of climate change.

To stay within the budget, global emissions would have to peak by 2020, and then become negative — with more CO2 being taken out of the atmosphere by plants and the oceans than is put into the air each year — by 2090.

To reach our 2025 goal, we'll need to more rapidly slow the growth of power sector greenhouse gas emissions so they peak within 10 to 15 years, and decline thereafter.

[Comment 25] To reach our 2025 goal, we'll need to more rapidly slow the growth of power sector greenhouse gas emissions so they peak within 10 to 15 years, and decline thereafter.

In as much that we have to peak GHG emissions within the next decade and see them rapidly dropping over following decades, the video presents is a well founded message.

The ability of a band to shape the temperature profile of the whole atmosphere should tend to be maximum at intermediate optical thicknesses (for a given band width), because at small optical thicknesses, the amounts of emission and absorption within any layer will be small relative to what happens in other bands, while at large optical thicknesses, the net fluxes will tend to go to zero (except near TOA and, absent convection, the surface) and will be insensitive to changes in the temperature profile (except near TOA), thus allowing other bands greater control over the temperature profile (depending on wavelength — greater influence for bands with larger bandwidths at wavelengths closer to the peak wavelength — which will depend on temperature and thus vary with height.

For both pathways, keeping within budget means that a sustainable emissions peak has to come very soon.

In fact, keeping 2ºC within reach means that even if Annex I emissions drop at a rate that's steep enough to bring them to the stringent edge of the 25 - 40 % range (that is, 40 % below 1990 levels in 2020), then non-Annex I emissions will need to have peaked and begun to decline by 2020.

We came up with a program to accomplish something audacious: stopping once and for all the centuries - long rise in global greenhouse gas emissions and seeing them peak, level off and begin to decline within the next five years.

The Paris agreement seeks no less than a peaking of greenhouse - gas emissions «as soon as possible» and a de-carbonized global economy within the second half of the century.

And after another quick scan, I find table SPM.6 from the Synthesis which says emissions would need to peak sometime before the middle of the century to limit temperature rises to under 4 degrees (with a peak by 2015 to achieve less than 2 degrees warming)... I think most would agree that some degree of «drastic action» is going to be required to achieve a peak in emissions within this time frame, particularly while we have guys like you running around, would you not?

The report concludes that global emissions must peak then decline rapidly within the next five to ten years for the world to have a reasonable chance of avoiding the very worst impacts of climate change.

By comparison, CO2 interacts with radiant energy, at an absorption / emission peak of ~ 15μm wavelength (within a spread from 13.5 to 17 μm).

Those trajectories considered here that do not peak near 2200 have all warmed to within a small fraction of their peak warming by this date, and therefore the emissions emitted in these pathways after 2200 only serve to maintain temperatures, and not to induce more warming.

A recent report by the German Advisory Council on Global Change (WGBU) assessed what it would take to have a good chance of remaining within the 2ºC guardrail.25 The study concluded that even a delay in the peaking year to 2015 means that global emissions must fall at a rate close to 5 per cent per annum.

Even with optimistic assumption about the peak year for global emissions and rates of emissions reductions thereafter, the best estimate is for warming to reach 4 °C in the 2070s or 2080s, well within the life - spans of children born today.

The take - home message: The report concludes that global emissions must peak then decline rapidly within the next five to 10 years for the world to have a reasonable chance of avoiding the very worst impacts of climate change.

Our analysis shows that China's emissions might not peak until 2030, but by then its annual emissions could amount to half of the carbon budget — what is allowed in order to stay within the 2 °C warming target.

«To avoid the worst outcomes, we need to immediately adopt an emission reduction scenario in which emissions peak within the next two decades and then decrease very significantly, replacing fossil fuels with cleaner energy sources like solar and wind.»
