Obama's big initiative will be some sort of cap-and-trade scheme for carbon dioxide emissions.
Back then, it took 7, 000 years for carbon dioxide to reach 80 ppm, Tans said.
In fact, he says, no one has come up with similar gismos for carbon dioxide.
Back then, it took 7, 000 years for carbon dioxide to reach 80 parts per million, Tans said.
Dan Kiselman, a Swedish astronomer, will use a telescope in the Canary Islands to look for carbon dioxide.
The Keystone plant in Pennsylvania tops the list for mercury emissions, and the Scherer plant in Georgia is the dirtiest for carbon dioxide emissions.
CNN: Nature - America's most wanted: Power plants urged to clean up their act
Rescuers have long monitored patients' breathing tubes for carbon dioxide to make sure the device was correctly placed in the windpipe instead of the esophagus.
As for carbon dioxide emissions, their impact is, at worst, minimal.
The flip side to this increased focus on reducing carbon dioxide emissions is that, industrially at least, the demand for carbon dioxide as an input into processes is increasing.
Land masses, and their inhabitants, emit methane without then sucking any of it back up, which makes inverse modelling easier than for carbon dioxide (which has sinks, in the form of photosynthesising plants, as well as sources).
The cap-and-trade program for carbon dioxide is modeled, generally, after an existing one to cut sulfur dioxide one that was enacted in 1990 as part of the Clean Air Act with the approval of the elder President Bush.
The estimate for atmospheric carbon dioxide for that period is two to four times preindustrial levels, or roughly between 560 parts per million and 1120 parts per million.
FORBES: Could Fish Fossils Help Us Better Predict Climate Change?
At the current low levels of atmospheric carbon dioxide, rubisco in C3 plants can be fooled into substituting oxygen molecules for carbon-dioxide molecules.
WSJ: Harrison H. Schmitt and William Happer: In Defense of Carbon Dioxide
European leaders have also agreed to institute new binding EU-wide targets for reducing carbon dioxide emissions.
The far North Atlantic is globally significant because it acts as a sink for atmospheric carbon dioxide.
CNN: Could volcanic eruptions signal boom time for ocean life?
Its most recent glitch was a leak that disabled the apparatus for removing carbon dioxide from the air.
For air capture to work it needs to find people with a real economic need for the carbon dioxide it produces.
This is not Spitzer's first time taking on utilities, but it is the first time he is suing them for releasing carbon dioxide, which is the gas released with every human exhale.
"The high latitude North Atlantic Ocean is a globally important ocean region, as it is a sink for atmospheric carbon dioxide and an area where deep water formation takes place, " Prof Achterberg observed.
In September 2009, the appeals court ruled that plaintiffs could sue American Electric Power Co. and five other leading utility companies for their carbon dioxide emissions (which had been already been approved by government issued permits).
But he went much further, acknowledging the scientific case for cutting global carbon dioxide emissions by 60% or more.
Hodel knew there was a demand for all that carbon dioxide.
FORBES: Sinopec's Clean Coal Plan Shows It's Set To Buy Chesapeake's Texas Oil Fields
The other raw material for photosynthesis, carbon dioxide, will be supplied as the exhaust from industrial plants such as power stations, oil refineries and natural-gas processors.
It would be a mistake to think of geo-engineering as a substitute for curbing carbon-dioxide emissions not merely because of the acidification of the oceans, but also because if you ever stop fertilising the oceans or spraying the atmosphere or whatever, the problem will rapidly return.
Last year a Dutch study found that draining Indonesian swamps to make way for oil-palm plantations resulted in 33 tonnes of carbon dioxide emissions for each tonne of palm oil produced, by speeding up the decomposition of the peaty soil.
Because producing a requisite amount of electricity from gas results in estimate about 50% of the carbon dioxide for the same coal-based electricity, the only way to meet the proposed standard is to capture the outgoing carbon dioxide, pipe it somewhere, and bury it.
FORBES: Guided By Questionable Science, The EPA Seeks To "Necessarily Bankrupt" The People
In theory, the country could see mandates for renewable fuel use, investment in the storage of carbon dioxide and punishment for companies that engage in price gouging.
That's hardly all that goes into making the case for the benefits of carbon dioxide.
WSJ: Harrison H. Schmitt and William Happer: In Defense of Carbon Dioxide
Critics point out, for instance, that carbon dioxide does not just warm the atmosphere.
That plan requires large power producers to purchase credits for each ton of carbon dioxide emitted.
