Not exact matches

The models also include the greenhouse gas emissions and other pollutants that result from these processes, and they incorporate all of that information within a global climate model that simulates the physical and chemical processes in the atmosphere, as well as in freshwater and ocean systems.

As roughly 30 percent of global permafrost carbon is concentrated within 7 percent of the permafrost region in Alaska, Canada, and Siberia, this study's findings also renew scientific interest in how carbon uptake by thermokarst lakes offsets greenhouse gas emissions.

To get a sense for how this probability, or risk of such a storm, will change in the future, he performed the same analysis, this time embedding the hurricane model within six global climate models, and running each model from the years 2081 to 2100, under a future scenario in which the world's climate changes as a result of unmitigated growth of greenhouse gas emissions.

(1) continue to actively promote, within the International Civil Aviation Organization, the development of a global framework for the regulation of greenhouse gas emissions from civil aircraft that recognizes the uniquely international nature of the industry and treats commercial aviation industries in all countries fairly; and

Because that's about how much time we have to stop the increase in greenhouse gas emissions and begin steep reductions that will bring emissions to near zero within another ten years at most, if we are to have any hope of avoiding the most catastrophic consequences of global warming.

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.

As we seek to increase production of oil and natural gas to meet growing global energy demand, we are committed to mitigating greenhouse gas emissions within our operations.

Globally, deforestation and land use change contributes to approximately 13 % of global greenhouse gas emissions, with deforestation representing the large majority of emission within that category.

Global warming is changing the movement of carbon within northern ecosystems to the point where the Arctic could become a net source, rather than sink, of greenhouse gas emissions.

In order to keep temperatures within this range, the IPCCâ $ ™ s Fourth Assessment Report argues that global greenhouse gas (GHG) emissions must start declining by 2015.2 For industrialized countries, which are responsible for most of the GHGs already in the atmosphere, this implies implementing drastic cuts immediately; the latest IPCC Report suggests that compared to 1990 levels, industrialized countries might have to reduce their emissions by 25 to 40 per cent by 2020 and 80 to 95 per cent by 2050.3 Thus, there is little time left to avoid the worst impacts of climate changeâ $» ambitious action is required now.

Using data collected by and within 160 countries, the researchers estimate that global tourism in 2013 accounted for greenhouse gas emissions equivalent to 4.5 billion metric tons of CO2, or about 8 % of global emissions that year.

A doubling of the pre-industrial levels of atmospheric CO2 of roughly 280 parts per million, which could occur within decades unless people curb greenhouse - gas emissions, could eventually boost global average temperatures by around 9 degrees C.»

Paragrap 17 «Notes with concern that the estimated aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined contributions do not fall within least - cost 2 ̊C scenarios but rather lead to a projected level of 55 gigatonnes in 2030, and also notes that much greater emission reduction efforts will be required than those associated with the intended nationally determined contributions in order to hold the increase in the global average temperature to below 2 ̊C above pre-industrial levels by reducing emissions to 40 gigatonnes or to 1.5 ̊C above pre-industrial levels by reducing to a level to be identified in the special report referred to in paragraph 21 below;»
