Although the future trajectory of dichloromethane is uncertain, without any regulations on emissions, it is likely concentrations will fall somewhere in between the ranges presented here.

Our new paper shows that «on the ground» management can help polar bears into a better future IF we also strongly mitigate temperature rise by lowering future emissions from their current trajectory.

Although this will significantly raise its projected greenhouse gas emissions, the present study has identified numerous measures which can be taken to shift this future development pathway on to a lower carbon and more climate friendly trajectory.

In the near term, federal policy could: i) level the playing field between air captured CO2 and fossil - fuel derived CO2 by providing subsidies or credits for superior carbon lifecycle emissions that account for recovering carbon from the atmosphere; ii) provide additional research funding into air capture R&D initiatives, along with other areas of carbon removal, which have historically been unable to secure grants; and iii) ensure air capture is deployed in a manner that leads to sustainable net - negative emissions pathways in the future, within the framework of near - term national emissions reductions, and securing 2 °C - avoiding emissions trajectories.

The future concentrations of LLGHGs and the anthropogenic emissions of sulphur dioxide (SO2), a chemical precursor of sulphate aerosol, are obtained from several scenarios considered representative of low, medium and high emission trajectories.

The trajectory of future emissions thus has the potential to greatly influence air quality over most of the world's highly populated areas.

Based on this source list, future CH4 emission trajectories depend upon such variables as volumes of fossil fuels used in the scenarios, regional demographic and affluence developments, and assumptions on preferred diets and agricultural practices.

Emission trajectories - These are projections of future emission pathways, or observed emission patterns.

The team will also look at future regional development trajectories, their emissions implications, and equity implications.

The main purpose of the first phase (development of the RCPs) is to provide information on possible development trajectories for the main forcing agents of climate change, consistent with current scenario literature allowing subsequent analysis by both Climate models (CMs) and Integrated Assessment Models (IAMs).1 Climate modelers will use the time series of future concentrations and emissions of greenhouse gases and air pollutants and land - use change from the four RCPs in order to conduct new climate model experiments and produce new climate scenarios as part of the parallel phase.

The latter two factors already vary greatly among countries, and national policies can affect future trajectories of GHG emissions directly as well as indirectly through policies affecting economic growth and (energy) consumption.

The paper by Granier et al. (2011) provides an assessment of a range of historical emissions data as context for the harmonized emissions used as a common starting point for the future trajectories of the RCPs.

While other areas such as industrial energy use and non-CO2 gases would be harder to incorporate, these upward shifts in ambition from willing actors will at a minimum make it more tractable for the U.S. to re-engage on a broader emissions reduction trajectory under a future administration.

The sources of uncertainty are many, including the trajectory of greenhouse gas emissions in the future, their conversion into atmospheric concentrations, the range of responses of various climate models to a given radiative forcing and the method of constructing high resolution information from global climate model outputs (Pittock, 1995; see Figure 13.2).

Depending on the balance between the anthropogenic drivers impacting marine pH, the trajectories of future pH of some coastal ecosystems will range from steep acidification, several-fold faster than expected from anthropogenic CO2 emissions alone, to basification.

Under that law, EPA's conclusion — that such emissions are pollutants that endanger the public's health and welfare — could trigger a broad regulatory process affecting much of the U.S. economy as well as the nation's future environmental trajectory.

A new Climate Change Authority, headed by former reserve bank governor Bernie Fraser, will advise the government on the future emissions caps within the emissions trading scheme, national emissions trajectories, and many other aspects of the scheme including the role of price floor and ceiling after the initial three years.

The exact warming resulting from this delay depends on the trajectory of future CO2 emissions but using one business - as usual - projection we estimate an increase of 3/4 °C for every 15 - year delay in CO2 mitigation.
