Sentences with phrase «than greenhouse gases»

Results on the importance and contribution from anthropogenic forcings other than greenhouse gases vary more between different approaches.

Now that the cold war is over, we have to generate a common enemy to support science, and what better common enemy for the globe than greenhouse gases?

The sources of black carbon — and its effects on climate — are even more diverse than greenhouse gases.

And it's more than a greenhouse gas problem — engine exhaust particles could increase warming by some 17 - 78 percent, the researchers say.

They also found that reasonable combinations of greenhouse gas and aerosol patterns are more easily detected than the greenhouse gas pattern on its own.

They also find that anthropogenic forcings other than greenhouse gases have offset about 60 % of the warming that would have occurred if greenhouse gases had acted on their own.

(12/03/2008) Producing biofuels from oil palm plantations established on degraded grasslands rather than tropical rainforests and peat lands would result in a net removal of carbon from the atmosphere rather than greenhouse gas emissions, report researchers writing in Conservation Biology.

However, the net effect in terms of forcing is only about 0.27 W / m ^ 2 — much less than greenhouse gas forcing.

Natural Variability Doesn't Account for Observed Temperature Increase In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed since 1880.

It's a staggering amount of carbon, but so far less than the greenhouse gases emitted by countries like the United States or China.

For comparison, the number is more than the greenhouse gas production than all of Canada combined, scientists said.

However, particles are more challenging to model than greenhouse gases, and soot particles are particularly tricky to simulate correctly.

On the other hand, scattering sulfate aerosols are less efficient than greenhouse gases in changing the surface temperature for a given forcing.

Russian physicists Galina Mashnich and Vladimir Bashkirtsev believe that solar variability is having more of an effect on global temperatures than greenhouse gases and expect the sun to enter a less active phase over the next few decades.

However, Stott et al. (2003b), using the same solar reconstruction but a different model, are not able to completely rule out the possibility that solar forcing might have caused more warming than greenhouse gas forcing over the 20th century due to difficulties in distinguishing between the patterns of response to solar and greenhouse forcing.

Such trends mean scientists and policymakers will have to factor in how synthetic climate forcers other than greenhouse gases will change temperature, rainfall and weather extremes.

It's pretty obvious to anyone who looks back far enough that air quality regulations have had a huge impact, at least when it comes to pollutants other than greenhouse gases.

The believers will say something like, «well, something makes the planet warmer than what the sun can do by itself — what else can it be other than greenhouse gases; CO2 in particular?»

IMF says in these countries, air pollution other than greenhouse gases, and congestion from incorrectly priced fuels, cause an extra $ 57.50 in damage per ton of carbon dioxide, although the damage is not from the CO2.

Air pollution other than greenhouse gases, and congestion from incorrectly priced fuels, cause an extra $ 57.50 in damage per ton of carbon dioxide, even though it is not the CO2 doing the damage.

• Some renewables decrease pollution other than greenhouse gases, pollutants that damage human health (as well as ecosystems and agriculture).

But if, as the Economist article suggests, the figure is lower, that could mean factors other than greenhouse gases are also responsible.

Many of the usual suspects seem to be taking this paper as a sign that NASA has published a report indicating that changes in aerosols are responsible for global warming; rather than greenhouse gases.

Post-1940s «Agricultural Intensification» Caused Deep Cooling, 400 % Crop Growth In a new paper published in Geophysical Research Letters, three MIT scientists assert that the human influence on the climate of the Central United States is dominated by agricultural activity rather than greenhouse gas (GHG) emissions.
