Sentences with phrase «decrease in emission rate»

Methane is a transient gas in the atmosphere, so it ought to plateau if the emission flux is steady, but the shape of the concentration curve suggested some sudden decrease in the emission rate, stemming from the collapse of economic activity in the former Soviet bloc, or by drying of wetlands, or any of several other proposed and unresolved explanations.

Not exact matches

Even if clouds were decreasing there would be the clear sky super greenhouse effect where the rate at which downwelling thermal radiation grows relative to increasing temperatures is actually higher in the tropics than the rate at which surface thermal radiation emissions increase.

First, the original emission rates of SO2 and H2SO4 (3 % of total anthropogenic SO2 emitted) in the model (including emissions, boundary conditions, and initial conditions) were decreased by a factor of 4 compared with the 2005 base case to be consistent with the decrease in measured ambient SO2 concentrations since 2005 (SI Appendix, section 1 and Fig.

The choice is between leaving CO2 emissions to the markets with every expectation of large and rapid decreases in CO2 emissions or pursuing a government regulatory and subsidy approach that is unlikely to achieve anything except a bitter political and legal fight, rapidly increasing electricity rates, and rapidly declining electricity reliability.

And even with strong international climate policies, more rapid decarbonization (the rate of decrease in emissions per unit of GDP) will require higher costs and major policy change.

Overall, the average annual SF6 emission rate for the Partnership has decreased approximately 87 percent from the 1999 baseline emission rate of 14.2 percent to 1.9 percent in 2013.

(5) explains the cause of the slowdown in global warming after around 2000 — cooling from increased Eastern SO2 emissions offset the warming caused by Western Clean Air efforts, resulting in a net slowdown in the rate of decreasing global SO2 emissions.

Danny, I meant a decrease in the emissions growth rate.

One may, however, question the studies that indicate very rapidly increasing and decreasing N2O emissions, given the main sources of N2O (these are mostly agricultural and will grow at a modest rate, in the future, but to some degree are also difficult to abate).

But in his book, Dr. Lomborg cites figures from the United States Census Bureau, the International Monetary Fund, the World Bank and the European Environment Agency to show that the rate of world population growth has actually been dropping sharply since 1964; the level of international debt decreased slightly from 1984 to 1999; the price of oil, adjusted for inflation, is half what it was in the early 1980's; and the sulfur emissions that generate acid rain (which has turned out to do little if any damage to forests, though some to lakes) have been cut substantially since 1984.

The observations of figure 17 - F dispel the myth that all the increase of the CO2 of the air is from anthropic origin; the anthropic emissions remaining in the air for a 5 years life time have surged since 2003 while the overall the CO2 growth rate has been slowly decreasing!

The US, which has had much more limited subsidies for wind and solar, has not experienced rapidly rising rates as yet (except in ultra-green California) and has decreased CO2 emissions significantly.

The projection from China is taken from Scenario 2 (a linear decrease in growth rate with emissions leveling off in 2030).

It means if CO ₂ emissions were decreased right now to a level that matches natural removal rate, that is, if atmospheric CO ₂ concentration flatlined from now on, in 70 years we could avoid a warming in the range of 0.35 °C to 0.88 °C.

The effect of this increase on the growth rate of atmospheric methane has been masked by a coincident decrease in wetland emissions, but atmospheric methane levels may increase in the near future if wetland emissions return to their mean 1990s levels.

According to analysis from Project Catalyst hitting this goal requires a 17 gigaton decrease in annual greenhouse gas emissions to 44 gigatons per year from the projected increase of global emissions of 61 gigatons by 2020 if we continue polluting at current rates (Figure 1).
