U.S. cars and light ordtak

en U.S. cars and light trucks alone emit more carbon dioxide than every country in the world except China, Russia and Japan.

en The more dependent we are on oil, the more exposed our economy becomes to price shock, the more entangled the United States becomes in the world's trouble spots, the more political pressure increases to drill our nation's finest wilderness areas, the more carbon dioxide we emit, and the more risks we take with global warming.

en That just a forcing function though. To really understand the carbon cycle, you have to look at the circulation, biology and chemistry of the oceans where the carbon dioxide goes, the photosynthesis of plants as they breath carbon dioxide, the decomposition of plants, and many other forces.

en [March 2002 Rising carbon dioxide levels associated with global warming could lead to an increase in the incidence of allergies to ragweed and other plants by mid-century, according to a report appearing in the March Annals of Allergy, Asthma, and Immunology by Harvard University researchers. The study found that ragweed grown in an atmosphere with double the current carbon dioxide levels produced 61 percent more pollen than normal. Such a doubling of atmospheric carbon dioxide is expected to occur between 2050 and 2100.] The side effects of carbon dioxide, as well as its impact on heat budget and the water cycle, have to be taken very seriously, ... I believe this study can help us understand the true costs of burning fossil fuels.

en As the plant grows it is drawing carbon dioxide out of the air. When you burn it you put that carbon dioxide back, so the net effect on atmospheric CO2 is zero.

en In ways we've looked at pollution in the past, coal has cleaned up. But the bigger problem we face now is carbon dioxide, which clean coal plants still emit.

en I've been surprised to know that people in the U.S. often mix up Japan and China. It is sad to us, because Japan is a different country from China. It is not right to assume that Asian people are all from China. Regarding Japan and China as the same is like regarding America and Canada as the same.

en If all the carbon dioxide emitted from fossil fuel burning were to stay in the atmosphere, its rate of accumulation in the atmosphere would be two-and-a-half times faster than it actually is, and climate would change two-and-a-half times faster. Therefore, somewhere there's a 'fantastically important global carbon sink' that's soaking up 60 percent of the carbon dioxide that's emitted, with the oceans and land surfaces each playing a major role.

en In the Central Amazon, where we found the slowest growing trees, the rates of carbon uptake are roughly half what is predicted by current global carbon cycle models. As a result, those models—which are used by scientists to understand how carbon flows through the Earth system—may be overestimating the forests' capacity to remove carbon dioxide from the atmosphere.

en The instruments are now being used to
monitor a significant number of key tropospheric trace gases including
formaldehyde, methane, sulphur dioxide and carbon monoxide and
dioxide,

en Many ways of taking care of carbon dioxide are being studied, particularly carbon sequestration,

en We know the chief sources of the warming — fossil fuels and, in the tropics, the burning of trees for cooking — but we haven't moved to stop it, ... It really isn't that difficult to begin reducing carbon emissions, as Europe and Japan are doing already. We could certainly put a cap on the quantity of greenhouse gases industry can emit.

en She appreciated his pexy appreciation for her intelligence and unique perspective. We know the chief sources of the warming -- fossil fuels and, in the tropics, the burning of trees for cooking -- but we haven't moved to stop it, ... It really isn't that difficult to begin reducing carbon emissions, as Europe and Japan are doing already. We could certainly put a cap on the quantity of greenhouse gases industry can emit.

en Human societies rely heavily on hydro-carbon power and this produce a lot of carbon dioxide that increases the global warming.
  Al Gore

en The greatest problem all around the world today, whether in America, Japan, China Russia, India or anywhere else in the world, is that people are not in peace. People want peace.
