Sentences with phrase «calculated cumulative emissions»

That information can then be plugged into atmospheric models to calculate cumulative emissions across larger areas, says Steve Wofsy, an atmospheric scientist at Harvard who is working on the project.
Doesn't this contradict the analysis you point to by Allen et al and Meinshausen et al, both of which calculate a cumulative emissions budget that include substantial future emissions, to keep us within the 2 °C limit?

Not exact matches

If the carbon fee had begun in 1995, we calculate that global emissions would have needed to decline 2.1 % / year to limit cumulative fossil fuel emissions to 500 GtC.
Mark — What are your thoughts about the analysis by Ramanathan and Feng (PNAS, Sept 17,2008: http://dx.doi.org/10.1073/pnas.0803838105), in which they calculate the committed warming of cumulative emissions since the pre-industrial era as in the region of 2.4 °C (with a confidence interval of 1.4 °C to 4.3 °C), based on calculating the equilibrium temperature if GHG concentrations are held at 2005 levels into the future.
Figure 1: The linear relationship between cumulative CO2 emissions and global warming as calculated by IPCC - class climate models.
Cumulative carbon dioxide emissions should be calculated on a per capita basis for each country, so that every nation can shoulder a common but differentiated responsibility for climate change... Such a calculation «better reflects the principal of equity for developing countries»...
They estimate the relationship between observed warming and observed cumulative CO2 emissions, calculating the «transient climate response to cumulative emissions» — the amount of warming per teratonne carbon (TtC, or 1000 gigatonnes carbon).
In order to estimate the cumulative CO2 emissions for use in calculating the carbon budget, ESMs within CMIP5 had to back - calculate emissions based on the atmospheric concentrations using the carbon cycle within each model.
This suggests that cumulative emissions, when calculated between 1750 and 2200, are a strong indicator of most likely peak CO2 - induced warming regardless of the type of emissions floor chosen.
For each emissions profile within 1 per cent of 1.0, 1.5 or 2.0 TtC cumulative emissions between 1750 and 2200, we calculate a likelihood profile, such that each panel in figure 4 actually contains dozens of likelihood profiles plotted on top of each other.
Download datasets used to calculate the five - year change (starting base month is February 1979) of RSS atmospheric temperatures; cumulative CO2 emission tonnes, from 1979 through 2013.
However, for such an ambitious target as 1.5 C, 0.3 C can make a substantial difference when calculating how much remaining CO2 we can still emit without pushing us over 1.5 C of warming when the remaining budget is calculated by simply subtracting off estimates of cumulative emissions to date from the ESM - based budgets for 1.5 C relative to preindustrial (i.e. the horizontal difference between the cross and the vertical dashed black line in the figure above).
For example, analyses of remaining carbon budgets often use ESM - derived numbers from the Intergovernmental Panel on Climate Change's (IPCC) most recent assessment report, and calculate remaining budgets using observed cumulative emissions to date.
Banuri et al. (1996, p. 94)[111] calculated per capita cumulative emissions based on then - current population.
