Ethanol adds to global warming

Ethanol adds to global warming

The widespread use of ethanol from corn could result in nearly twice the greenhouse gas emissions as the gasoline it would replace because of expected land-use changes, researchers concluded Thursday. The study challenges the rush to biofuels as a response to global warming.

The researchers said that past studies showing the benefits of ethanol in combating climate change have not taken into account almost certain changes in land use worldwide if ethanol from corn — and in the future from other feedstocks such as switchgrass — become a prized commodity.
"Using good cropland to expand biofuels will probably exacerbate global warming," concludes the study published in Science magazine.
The researchers said that farmers under economic pressure to produce biofuels will increasingly "plow up more forest or grasslands," releasing much of the carbon formerly stored in plants and soils through decomposition or fires. Globally, more grasslands and forests will be converted to growing the crops to replace the loss of grains when U.S. farmers convert land to biofuels, the study said.

California to Control Global Warming

A bold proposal to control global warming gases from California automobiles was pulled Tuesday as the Assembly cut off debate on measures carried over from last year.

Assemblyman Ira Ruskin (D-Redwood City) said he would reintroduce the California Clean Car Discount Act next month with unspecified amendments that he hopes will satisfy undecided Assembly members. The bill would impose one-time surcharges of up to $2,500 on gas guzzlers and use the money to give rebates on cars and light trucks that emit less carbon dioxide and other greenhouse gases.Ruskin said he was about four votes short of the total needed to pass the bill, which was strongly opposed by auto dealers and manufacturers.

Global warming a hoax

As a plant scientist, I am concerned that Idaho and most states are planning to limit and reduce Carbon Dioxide (CO2) emissions. This is being done to supposedly reduce global warming. The states are adopting the 1997 Kyoto Climate Treaty which the U.S. Senate rejected 95-0 because it would destroy our economy while exempting developing nations like China which do not control pollution.CO2 is not a pollutant and is not causing global warming. CO2 is necessary for life on the planet, as plants utilize CO2 to produce the oxygen we breathe and the food we eat! Global warming now and cooling of the 40’s to mid-seventies is caused by solar activity. We have an active sun now! The earth has been warming for 300 years with most of the increase prior to increased CO2 levels.
Also, 279 research project reports have shown that increasing CO2 increases crop production. Higher levels of CO2 is creating a lush environment for plants and animals and will improve the health (more oxygen), longevity and prosperity of all people.Over 20,000 U.S. scientists have signed a petition opposing man-caused global warming and the benefits of increased CO2 levels, but the mass media totally ignore them. John Coleman, founder of The Weather Channel, stated that man-caused global warming is the biggest hoax ever perpetrated on mankind.The biased United Nation’s panel and Al Gore are promoting a lie to scare us into a U.N. global government. The bottom line is that we need to produce more energy, not less. We have a 300 year U.S. supply of crude oil and unlimited nuclear power. There is no scientific reason to limit CO2 production because it is not causing global warming!
