Reducing emissions of those gases will require getting people to change their behavior in many different ways, some of them impossible to identify until we have a much better grasp of green technology.
Continued emissions of these gases will cause further climate change, including substantial increases in global average surface temperature and important changes in regional climate.
Mr. Hagel has repeatedly said in recent months that he believes global warming is at least partly caused by
emissions of gases from human activities, but he has opposed both the Kyoto Protocol and legislative moves to limit carbon dioxide emissions.
David Archer of the University of Chicago has again done yeoman's service by posting a detailed look at this paper on Realclimate (along with last Monday's methane paper, discussed here, providing a new and higher estimate
of emissions of this gas across the United States).
Natural
emissions of the gas make up about 40 % of the 440 Teragrammes of carbon emitted in the form of methane each year; the bulk of these natural emissions come from wetlands.
Despite the well - known fact that
human emissions of the gas make up just a fraction of one percent of the greenhouse gasses present naturally in the atmosphere, supporters of man - made global - warming theories insist that humanity must, under UN guidance, destroy the economy to reduce emissions and stave off alleged disaster.
Martin Zimmerman, vice president of governmental affairs for Ford, said in a conference call Yesterday that the Kyoto agreement sets an unrealistic timetable for reducing
emissions of gases linked to global warming, and excludes developing nations where such emissions are likely to increase.
If similar results are found in other urban areas, then unknown urban sources could account for 7 to 15 per cent of humans»
global emissions of the gas, the researchers calculate — far more than was thought (Geophysical Research Letters, DOI: 10.1029 / 2009gl039825).
Many in the developing world see the whole idea of geoengineering as a ruse by industrialised nations to excuse them from making serious cuts in
emissions of the gases causing climate change.
Due to the inclusion of the response times for the climate system, the GTP values for pulse
emissions of gases with shorter lifetimes than the reference gas will be lower than the corresponding GWP values.
But frequently the greatest community liability — and the greatest environmental danger — is
smelly emissions of gases (primarily methane) from the large lagoons characteristic of the industry
Interestingly, the human -
induced emissions of the gases in Southern Asia, including China and India, had a larger net warming effect compared to other areas.
In addition, developed nations are making mistakes when
reporting emissions of the gases, called hydrofluorocarbons, or HFCs, to the U.N. Framework Convention on Climate Change (UNFCCC), the study finds.
The Edison Electric Institute, which represents electric companies in all 50 states, declined to comment directly on the EPI's findings, but said the industry had already reduced
emissions of the gases blamed for causing climate change.
«What we need is «ground truth» — something reporting from the surface saying, «Hey, there's a Marsquake,» or «Hey, there's
unusual emissions of gas,»» McGovern added.
A team of researchers from universities in Sweden and the US says methane is increasing in the atmosphere fast enough for
emissions of the gas possibly to rise by between 20 % and 50 % before the end of the century.
Yet as New Englanders trade in sport utility vehicles for hybrid cars and move toward more climate - friendly technologies, the exporting of old equipment represents a significant leak in the expanding worldwide effort to
plug emissions of gases that trap the sun's heat.
James E. Hansen, the top climate scientist at NASA, was quoted in The New York Times in January as saying he had been threatened with «dire consequences» by some NASA political appointees if he continued to call for limits
on emissions of gases linked to global warming.
The
anthropogenic emissions of these gases have been increasing rapidly since the beginning of the industrial era and their mean lifetime in the atmosphere is long (about 10 years for CH4, 100 years for N2O and much longer for CO2).
This open - source research paper
investigates emissions of gases and particles from the combustion of fossil fuels and biofuels in Africa, that are expected to increase significantly in the near...
Without new agreements to foster emerging technologies such as solar and wind power and burial of carbon dioxide underground,
world emissions of the gas should hit 40.4 billion metric tons by 2030, up from 29 billion metric tons in 2006, said the Energy Information Administration, the independent statistics arm of the Department of Energy.
Guenther gained prominence through his systematic advancement of groundbreaking measurements and modeling of biogenic emissions, which led to his development of the Model
of Emissions of Gases and Aerosols from Nature, or MEGAN.
The EU considers itself at the forefront of the fight against climate change and as a bloc it's on track to meet its obligations under the Kyoto Protocol, which limits
the emissions of gases that warm the planet.
The potential problems are of such magnitude, however, that if we wait for irrefutable evidence before taking steps to halt
the emission of gases and the destruction of rainforests, it will be too late (quite literally) to «stem the tide».
Stabilizing — and ultimately eliminating —
emissions of that gas will be the key to avoiding catastrophic climate change.
This stability in methane levels had led scientists to believe that
emissions of the gas from natural sources like livestock and wetlands, as well as from human activities like coal and gas production, were balanced by the rate of destruction of methane in the atmosphere.
The aim will be to target new cuts in
emissions of the gases that cause acid rain, to give maximum benefit to the environment.
