Crucially, lower greenhouse gas emissions scenarios did not always lead to widespread tree mortality.

The researchers analyzed climate suitability projections over time for 513 species across 274 national parks, under a high and low greenhouse gas emission scenario.

The low greenhouse gas emissions scenario (RCP4.5 *) delays average climate departure to 2069 but does not prevent it.

Not exact matches

Headed toward an 8 F rise in warming Other such low - probability but high - risk scenarios mentioned in the report include ecosystem collapses, destabilization of methane stored in the seafloor and rapid greenhouse gas emissions from thawing Arctic permafrost.

She and her team then projected excess deaths from heat under a low and a high greenhouse gas emissions scenario, incorporating adaptation patterns.

Two global scenarios, one of low greenhouse - gas emissions and the other of medium emissions, were created for each model.

If nations continue to increase their emissions of greenhouse gases in a «business - as - usual» scenario, the U.S. ratio of daily record high to record low temperatures would increase to about 20 to 1 by midcentury and 50 to 1 by 2100.

In our study we also showed that, while difference between high and low immigration scenarios is 70 Mt of greenhouse gas emissions in Australia's by 2020, the world's greenhouse gas emissions would increase by less than half of this amount since immigrants to Australia come from countries that have per capita emissions levels less than half of Australia's (around 42 %).

Shifting currents, increased freshwater input from melting sea ice and glaciers, and changes in upper and lower sea - level circulation patterns are already occurring, and they'll progress rapidly if anthropogenic greenhouse gas emission continues under a business - as - usual scenario.

Heat stress is projected to increase as a result of both increased summer temperatures and humidity.55, 61 One study projected an increase of between 166 and 2,217 excess deaths per year from heat wave - related mortality in Chicago alone by 2081 - 2100.62 The lower number assumes a climate scenario with significant reductions in emissions of greenhouse gases (B1), while the upper number assumes a scenario under which emissions continue to increase (A2).

The modeling results indicate that, if nations continue to increase their emissions of greenhouse gases in a «business as usual» scenario, the U.S. ratio of daily record high to record low temperatures would increase to about 20 - to - 1 by mid-century and 50 - to - 1 by 2100.

However, the model results are important because they show that, in all likely scenarios of future greenhouse gas emissions, record daily highs should increasingly outpace record lows over time.

Lam and team used climate models from the Intergovernmental Panel on Climate Change to examine the economic impacts of climate change on fish stocks and fisheries revenues under two different emissions scenarios: a high - emission scenario, in which the rates at which greenhouse gases are pumped into the Earth's atmosphere continue to rise unchecked, and a low - emission scenario under which ocean warming is kept below two degrees Celsius.

The radiative forcing estimates are based on the forcing of greenhouse gases and other forcing agents.5 The four selected RCPs were considered to be representative of the literature, and included one mitigation scenario leading to a very low forcing level (RCP2.6), two medium stabilization scenarios (RCP4.5 / RCP6) and one very high baseline emission scenarios (RCP8.5).

The emission pathway is representative of scenarios in the literature that lead to very low greenhouse gas concentration levels.

Over the remainder of this century, aggressive and sustained greenhouse gas emission reductions by the United States and by other nations would be needed to reduce global emissions to a level consistent with the lower scenario (B1) analyzed in this assessment.15

Dr. Romm helped lead the administration's climate technology policy formulation, and initiated, supervised, and publicized a comprehensive technical analysis by five national laboratories of how energy technologies can reduce greenhouse gas emissions at low - cost: Scenarios of U.S. Carbon Reductions.

A few years ago Hal Turton and I modeled the effect of high versus low immigration scenarios on expected growth of Australia's greenhouse gas emissions.

A report by the Sussex Energy Group and Tyndall Centre for Climate Change Research entitled China's Energy Transition: Pathways for Low Carbon Development set out four different scenarios for low - carbon development in China in an attempt to demonstrate how China's economic development can be decoupled from carbon emissions growth — allowing its economy to expand by some 8 to 13 times while presumably stabilizing greenhouse gas concentrations in the atmospheLow Carbon Development set out four different scenarios for low - carbon development in China in an attempt to demonstrate how China's economic development can be decoupled from carbon emissions growth — allowing its economy to expand by some 8 to 13 times while presumably stabilizing greenhouse gas concentrations in the atmosphelow - carbon development in China in an attempt to demonstrate how China's economic development can be decoupled from carbon emissions growth — allowing its economy to expand by some 8 to 13 times while presumably stabilizing greenhouse gas concentrations in the atmosphere.

That's in the IPCC AR4 Working Group 1, Summary for Policymakers, so one doesn't have to read very far to see what the IPCC actual projections are... that the projected trends are significantly lower than what Monckton claims and the fact that they are fairly scenario - independent over the next 20 years or so (which isn't that surprising given that it takes a while for the emissions in the various scenarios to diverge significantly and that half of the rise is projected to be due not to ANY additional emissions but simply to the greenhouse gases already present in the atmosphere).

The rate of increase depends on whether global greenhouse gases follow a low or high emission scenario.
