Now Rogers faces a potentially crippling threat--a "stroke-of-the-pen risk, " he calls it--if Congress imposes the wrong kind of controls on global-warming gases.
For the last five years the UN has run a program to encourage developing countries to cut down on emissions of global-warming gases.
Converting cow manure into methane biogas is said to be environmentally friendly, instead of allowing manure to decompose and create global warming gases.
There is a debate among environmentalists now about whether the move away from nuclear power will actually lead to a rise in emissions of global warming gases.
Viewed that way, the agreement to fund reforestation projects is an important development because it addresses the source of 20% of global warming gases while connecting developing and industrial economies, he said.
So they sent a delegation to talk about other issues and to talk about businesses that could participate in the US approach which is one of a voluntary effort to cut global warming gases.
This news confounds the narrative about coal that has started to take hold in the U.S. The story goes that coal, nudged toward extinction by a glut of cheap, domestic natural gas and stiffening regulations, will begin to disappear as a fuel source and cause emissions of global-warming gases to decline.
FORBES: As Coal Use Drops In U.S., China and India Burn Even More
To see if insects really might be a more sustainable food source than livestock, Oonincx and his colleagues analyzed what global warming gases insects might generate as a result of respiration, the production of their feed, distribution networks to stores where they would get sold and emissions from the heating of climate-controlled rearing facilities.
This type of shift has occurred repeatedly in the last century, both before and during (modest) global warming from greenhouse gases.
FORBES: Climate Change Alarmists Can't Seem To Buy A Major Hurricane
That has prompted some to speculate that the Earth may be entering another cool period that could offset the warming caused by greenhouse gases trapping heat in the planet's atmosphere.
The warming effect caused by greenhouse gases rose 29% since 1990 and 1.4% over the last 12 months ending Dec. 31, 2010.
But the law's supporters argue that other places will inevitably regulate greenhouse gases as global warming begins to bite and that Californian businesses will benefit from being in the vanguard of this trend.
The academics advocate concentrating first on short-term fixes for greenhouse gases or other warming agents, such as black carbon - particles emitted from the incomplete burning of fossil fuels, principally in diesel engines and wood stoves.
These match climate models' predictions of what happens when warming is induced by greenhouse gases better than it matches predictions of the result of changes in the sun's activity, the main alternative hypothesis for what might be causing the climate to change.
The earth, after all, may be going through one of its warming phases whether we release greenhouse gases or not.
They export large amounts of wastes including household and industrial wastes, waste water and the gases linked with global warming.

Consider the Kyoto Protocol, an international agreement between 181 countries designed to reduce the emissions of gases that cause global warming.
Global warming theory holds that certain atmospheric gases warm the earth.
California, of course, has led the way toward cleaner vehicles, often adopting stricter laws than the federal government to control greenhouse gases and combat global warming.
FORBES: With Driverless Cars, Once Again It Is California Leading The Way
Electric cars help fight global warming because they contribute less greenhouse gases to the atmosphere than gasoline-powered cars, even if the electricity is made in a coal-fired power plant.
The regulations also bar federal agencies from assessing emissions of the gases blamed for global warming on species and habitats, a tactic environmentalists have tried to use to block new coal-fired power plants.
On energy, 53% of survey participants said they approved of a proposal that would require companies to reduce greenhouse gases that cause global warming, even if it would also mean higher utility bills for consumers.
At one panel discussion, Jan Shori, general manager of the Sacramento Municipal Utility District, the sixth-largest community-owned electric utility in the country, noted the state of California's ambitious goals to reduce carbon dioxide and other gases blamed for global warming.
Well, that's the only idea that we're trying to talk about when it comes to these greenhouse gases that are causing global warming.
This shows the behind-the-scenes work of the United States, the one G8 nation that did not sign the Kyoto global warming protocol and agree to reduce greenhouse gases.
The problem: Harnessing energy that doesn't generate the gases said to lead to global warming remains a difficult, gritty business.
If you believe that man-made gases are the cause of global warming, then address methane, which has a much more devastating effect than CO2.
That is because cars produce local air pollution, which damages human health and the environment, and also produce greenhouse gases, which contribute to global warming.
Human influence on climate change is not accepted by everyone but most scientists now believe that we are responsible for warming the world through the large amounts of gases released by our industries.
