Sentences with phrase «emissions curves for»

He restated the longstanding mantra from China on climate, saying the responsibility for blunting emissions curves for greenhouse gases will remain with industrialized powers for a long time to come.

(Note, by the way, that what is true for a radiating object is that the amount of radiation emitted AT ANY PARTICULAR WAVELENGTH is an increasing function of the temperature, a fact that is not always obvious because people often tend to normalize the emission curves when showing emission curves for different temperatures on the same graph.)

«That flat torque curve is there for emissions reasons, because it suits the drive - cycle used in testing,» says Turner.

But the torque curve is more linear for better off - line performance, said John Schutz, director of powertrain and emissions for Nissan Research and Development Inc..

A long list of technologies has been engineered to provide 255 horsepower, a unique three - stage torque curve, very low emissions, high fuel efficiency for a truck, and instantaneous throttle response.

Eventually, by shaving away the two tails of the global development and emissions curve, while also aggressively pushing for efficiency and new energy choices among the global middle class, a happy medium with far lower emissions could be achieved, according to the paper.

He recently wrote a Policy Forum paper in Science reviewing his and other research on widespread misunderstanding of this kind of risk, including a 2007 study he was a co-author of in which 84 percent of 212 M.I.T. participating grad students drew curves for proposed emission trends that would result in concentrations continuing to climb.

He wrote a fascinating piece for the journal Science on the results of a study testing hundreds of very smart M.I.T. students to see if they could draw an emissions curve that would stop the level of carbon dioxide in the atmosphere from rising.

The task on emissions is twofold — to bend the curve of gas releases using regulations, incentives, education and standards, but (more importantly, to me) also to build the intellectual infrastructure and innovative, globally - collaborative culture that will be required for the next generation to take that curve down toward zero even as humanity's energy needs continue to rise.

Thus, solar cycle variations may or may not explain this «dip» (one similar - looking dip in two curves is not a significant correlation and could easily be coincidence; there is a better - founded explanation for this «dip» resulting from cooling by aerosol emissions — see the figure from Hansen et al. coming up below).

The TAR showed sea level rise curves for a range of emission scenarios (shown in the Figure above together with the new observational record of Church and White 2006).

Apparently, environmental Kuznets curves work in the case of cleaning up car emissions because localised pollution provokes local pressure to improve the environment, whereas CO2 emissions are generalised and so subject to the «tragedy of the commons» (I typed «tragedy of the cosmos», which would be a good title for something or other).

Modeled carbon isotope curves (CIEs) for 3 different emissions sources over 4 different emission timeframes.

Lots of black body curves but not used to thinking about emission spectrum for a gas.

Taken another way, from a climate perspective, the total area under the emissions trajectory matters more for peak warming than the shape of that curve.

Fitting CDIAC emissions and land - use - change data to the Keeling curve gave a much better fit at 285 years than 287, so for the purposes of illustrating the follownig I've gone with that as a round number for the time being though clearly this needs closer inspection.)

However please understand that I'm using CO2 as a relatively well - quantified proxy (thanks to both the CDIAC data and the Keeling curve) for all climate - relevant side - effects of rising human population and technology, of which CO2 emissions is just one component.

Even if it increases for population (i.e. population grows more slowly in future), any matching decrease in doubling time for per - capita energy consumption will offset that increase and CO2 emissions will therefore continue to follow the curve.

That would not really impact the emissions curve worldwide for very long.

Also, when you compare the mathematical growth curves for atmospheric CO2 and human emissions the numbers for the RE simply do not add up.

And for those of you who are not as familiar with it, essentially what the Paris agreement did was, for the first time, mobilize 200 nations around the world to sign up, agree to specific steps they are going to take in order to begin to bend the curve and start reducing carbon emissions.

By contrast, RCP 8.5 seems fairly close to what we are doing now — though with the agreement of the US and China, the world's largest emitters, to curb emissions, and with optimism in the air for international agreement in Paris at the end of 2015, there is some room at present to hope that we may, over the next few years, begin to bend the Keeling curve downward a bit.

What I do not see is that what you suggest would have any significant impact on changing the growth curve for CO2 emissions worldwide.

-- New technology of this sort tends to follow an exponential growth curve, so that if properly managed it could become mature within a few decades, being then able to balance existing emissions and start a drawdown process that could quickly make up for the previous century's emissions.

This occurs because the cumulative totals include contributions for portions of the emissions floor that are emitted after the time of peak warming, which can have no effect on peak warming, as illustrated by the green curves in figure 1.

If one were to take the model and plot a curve of emission versus wavelength rather than simply summing up the values (integrating over wavelength), it would show a spectral curve of a black body at 288.2 k with the absorption lines of the atmosphere dipping down to the point where there is a spectral curve for a lower temperature at which there is emission going on in the wavelength bands associated with ghg absorption.

The steepness of these curves superimposed on actual national ghg emissions levels is an indication of the enormity of the challenge for the international community because the emissions reduction curves are much steeper than reductions that can be expected under projections of what current national commitments are likely to achieve if fully implemented.

The chart's two ten - year moving average curves for the respective periods indicate a similarity that is striking, especially considering that modern human CO2 emissions are many multiples larger than the pre-1950 emissions.

Expensive short term acitons won't change the long term curve for emissions.

However, we know that the emission has been increasing for those 20 years throughout, and hence the CO2 concentration curve should be superlinear.

«Maybe the single most encouraging factor here is that the [climate] policies that China has put in place are in fact beginning to bend its emissions curve downward,» says Elliot Diringer, executive vice president of the Center for Climate and Energy Solutions, a nonprofit in Arlington, Va..

The emission curve (looking down from space) for the tropical Pacific in «clear - sky» conditions (ie, ignoring the 65 % of the time that clouds are present) tells an interesting story very similar to what the top post article says.

[16] Nasir M, Rehman F. Environmental Kuznets curve for carbon emissions in Pakistan: an empirical investigation.

There has to be an exploration of ways where these two seemingly opposed issues of economic development and low carbon can actually become complementary Unfortunately there is no historical precedent for an increase in energy without increased greenhouse gas emissions, which makes me extremely skeptical of «greenhouse gas Kuznets curves.»

Here emission curves are developed for advanced biofuel supply chains to enhance understanding of the relationship between biofuel supply and its potential contribution to climate change mitigation while accounting for landscape heterogeneity.

Even a casual inspection of the curves shows that the Paris pledges from the big three will provide no room for future emissions for all of the other countries in the 2 degree case.

If CO2 emissions from fossil fuels were the primary driver of the observed increase in CO2 the drop in CO2 emissions from 31915.9 mt in 2008 to 31338.8 mt in 2009 followed by the rapid increase to 33158.4 mt in 2010 would have influenced this curve in some noticible fashion if your contention about CO2 emissions from fossil fuels being the prime source for the observed increase is correct.
