Sentences with phrase «cumulative carbon emissions over»

In addition to it's focus on temperature increase, the report also suggests the use of cumulative carbon emissions over time as a valuable metric for linking emissions to impacts.

Not exact matches

Extrapolating from their forest study, the researchers estimate that over this century the warming induced from global soil loss, at the rate they monitored, will be «equivalent to the past two decades of carbon emissions from fossil fuel burning and is comparable in magnitude to the cumulative carbon losses to the atmosphere due to human - driven land use change during the past two centuries.»

But a carbon tax that increases over time at a persistent and predictable rate would minimize the expected economic cost of achieving any climate target (targets that depend, given the way the climate system works, on cumulative emissions over many decades).

Holding concentrations or temperature (more remotely) to a particular target therefore means limiting cumulative emissions of, say, carbon over time... a limited amount of time if we are talking about an iterative approach, and over a long period of time if we are talking about reducing the likelihood of some very nasty consequences well after we (but not our grandchildren — if we are lucky enough to have some) are gone.

They argue that keeping the most likely warming due to CO2 alone to 2 °C will require us to limit cumulative CO2 emissions over the period 1750 — 2500 to 1 trillion tonnes of carbon.

A carbon budget is the cumulative amount of carbon dioxide (CO2) emissions permitted over a period of time to keep within a certain temperature threshold.

By aggregating savings since 2008, this equates to a cumulative 8,178,000 tonnes of carbon emissions that have been avoided over the entire period.

They could cut cumulative carbon dioxide emissions by 34 billion metric tons, more than the total emissions from fossil fuels in this country over six years.

A number of recent studies have found a strong link between peak human - induced global warming and cumulative carbon emissions from the start of the industrial revolution, while the link to emissions over shorter periods or in the years 2020 or 2050 is generally weaker.

«In our mor recent global model simulations the ocean heat - uptake is slower than previously estimated, the ocean uptake of carbon is weaker, feedbacks from the land system as temperature rises are stronger, cumulative emissions of greenhouse gases over the century are higher, and offsetting cooling from aerosol emissions is lower.

Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.

Overall, although natural gas is a non-renewable fossil fuel that emits carbon dioxide, the cumulative emissions saved by fuel switching over the next decade from coal to natural gas are likely to prove far cheaper than the removal of carbon dioxide from the atmosphere in future decades.

Because all 2013 Intergovernmental Panel on Climate Change scenarios — except Representative Concentration Pathway 2.6 (RCP2.6), which leads to the total radiative forcing of greenhouse gases of 2.6 W m − 2 in 2100 — imply that cumulative carbon emission will exceed 1,000 Gt in the twenty - first century, our results suggest that anthropogenic interference will make the initiation of the next ice age impossible over a time period comparable to the duration of previous glacial cycles.»
