Sentences with phrase «same average emissions»

Not exact matches

This average meal uses up to 17 times more petroleum products, and increases carbon dioxide emissions by the same amount, compared to an entirely local meal.

In his new paper, Lovejoy applies the same approach to the 15 - year period after 1998, during which globally averaged temperatures remained high by historical standards, but were somewhat below most predictions generated by the complex computer models used by scientists to estimate the effects of greenhouse - gas emissions.

Keystone XL itself would exacerbate that — the U.S. State Department notes that the greenhouse gas emissions from just the pipeline's pumps would be 4.4 million metric tons per year, roughly the same as one average U.S. coal - fired power plant.

On the contrary — averaging fuel consumption of 9.0 litres / 100 kilometres (equal to 26.1 mpg US) and CO2 emissions of 210 grams per kilometre in the EU test cycle, the new top model offers the same superiority also in this respect as the BMW Z4 sDrive35i with Sport Automatic.

The same goes for the CO2 - minimising BMW 320d EfficientDynamics Edition, whose peak output of 120 kW / 163 hp contrasts with average fuel consumption in the EU driving cycle of 4.1 l / 100 km (68.9 mpg imp) and CO2 emissions of 109 g / km.

At the same time a 5.9 L / 100 km combined fuel consumption average is claimed, along with CO2 emissions of just 139g / km.

63 percent of respondents said the United States should move forward to reduce greenhouse gas emissions, regardless of what other countries do... In the same poll, the public supported — by a margin of 63 percent to 37 percent — requiring electric utilities to produce at least 20 percent of their electricity from renewable energy sources, even if that would cost the average household an extra $ 100 per year.»

Absent emission, absorption, reflection, scattering, and refraction outside of a sphere with radius 1, and assuming steady state, the flux coming out of such a sphere is the same as the flux coming out of any closed surface enveloping that sphere; the area of a sphere is proportional the square of the radius, so the average flux per unit area going through successively larger spheres follows an inverse square law.

For a small amount of absorption, the emission upward and downward would be about the same, so if the upward (spectral) flux from below the layer were more than 2 * the (average) blackbody value for the layer temperature (s), the OLR at TOA would be reduced more than the net upward flux at the base of the layer, decreasing CO2 TOA forcing more than CO2 forcing at the base, thus increasing the cooling of the base.

2: Our Changing Climate, Key Message 5).2 Regional climate models (RCMs) using the same emissions scenario also project increased spring precipitation (9 % in 2041 - 2062 relative to 1979 - 2000) and decreased summer precipitation (by an average of about 8 % in 2041 - 2062 relative to 1979 - 2000) particularly in the southern portions of the Midwest.12 Increases in the frequency and intensity of extreme precipitation are projected across the entire region in both GCM and RCM simulations (Figure 18.6), and these increases are generally larger than the projected changes in average precipitation.12, 2

California, which leads the «union» states in carbon - reducing policies, cut emissions by 1.5 million metric tons in 2013 (compared with 2012); at the same time, its economy grew at a faster pace than the national average.

Christy is correct to note that the model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).

If global greenhouse gas emissions continue to rise at the same pace that they did in the first decade of this century, ski resorts could see half as many sub-freezing days compared to historical averages by late century.

Climate economists argue, for instance, for a globally harmonized carbon tax even as they acknowledge the extraordinary moral, political and economic obstacles to asking the average African to pay the same toll on her emissions as the average European.

I think it's worth noting that even running on pure coal - electricty, a plug - in hybrid electric today would have much lower emissions of greenhouse gasses than the average new car today running on gasoline, and about the same emissions as a regular hybrid.

For all of its warnings, and despite a steady escalation of greenhouse gas emissions into the atmosphere, the planet's average surface temperature has remained pretty much the same for the last 15 years.

Projected global average temperature rise above pre-industrial levels under a range of future scenarios, «business as usual» (BAU), which assumes no mitigation efforts are made (RCP8.5); «mitigation», which assumes moderate emissions (RCP4.5) without negative emissions, «carbon dioxide removal» (CDR), which assumes moderate emissions with long - term CO2 removal; and «solar radiation management» (SRM), which is the same as the CDR pathway but also includes enough SRM to limit temperatures to 1.5 C by 2100.

Gensler's work on designing more energy efficient buildings saves the equivalent of 3.2 years» worth of carbon emissions from an average coal power plant — the same as taking 2.34 million passenger vehicles off the road for one year.

As a result of declining demand and this generation shift, power sector emissions fell by roughly the same amount in 2017 as the 2005 - 2016 annual average (Figure 2), though less than in 2016 and 2015 specifically.

Each sticker will include an index that compares the emissions of global warming gases from the vehicle with the average projected emissions from all vehicles of the same model year, and identifies the vehicle model within its class with the lowest emissions of that model year.

Say I have data on average precipitation for the last 30 years in the Southwest United States, as well as simulations from 20 different climate models of current and future precipitation in the same region, and I want to know what the expected change in precipitation will be at the end of this century under a specific emissions scenario.
