Global Warming on Earth Has Begun!The greatest priority for Earth at this time, is not to handle our monetary system, the corrupt politicians, drugs, the news media or even the atomic bomb. The problem is the continuous and expanding byproducts from burning fossil fuels i.e. pollution. "Since 1850 there has been a mean rise in global temperature of approximately 1� C (approximately 1.8� F). It was thought that this rise could just be part of a natural fluctuation; such fluctuations have been recorded for tens of thousands of years and operate in short-term as well as long-term cycles. " However, 1995 was the warmest year on record, according to the British Meteorological Office. A United Nations panel of scientists attributed the warming to human influence and predicted that if greenhouse-gas emissions [carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons] are not reduced, the average global temperature will rise by 1.0� to 3.5� C (1.8� to 6.3� F), with a best estimate of 2.0� C (3.5� F), by 2100, causing sea level to rise by 20 inches; further warming an sea-level rise would follow. The potential consequences of global warming are so great that many of the world's top scientists have urged immediate action and have called for international cooperation on the problem. How Bad is Global Warming - and What is Global Warming?The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP). The IPCC conference in Rome 1995 concludes that there are now clear signs of man-made climate changes, and that pollution from our cars, trucks, factories and power plants is a cause of it. The figure below show the current global temperature and the future predictions. You may also read more about these scary facts and statistics from NCDC, including the increasing tornado trends and the above average rain-falls. NASA scientists have announced that 1995 was the hottest year on record. The year saw killer heat waves from Chicago to Moscow to parts of India, a record number of tropical storms in both the Atlantic and the Pacific, and resurgent tropical diseases, like dengue fever. Dengue fever, a painful life-threatening disease endemic to tropical regions, broke out on the Texas border in the fall of 1995. (See also The National Climatic Data Center (NCDC), which is the world's largest active archive of weather data.)
Expected consequences of increased greenhouse effect are many. 1996 began with devastating snow storms and floods along the East Coast, a major heat wave on the West Coast and aberrant weather patterns in the Heartland of the United States. National Oceanic and Atmospheric Administration (NOAA) scientists report that these weather extremes, even the snow storms, are consistent with what global climate change is likely to bring. Here is an article on President Clinton calling for steps in curbing global warming. What is the Solution to Global Warming?One possible solution is to capture and store CO2 - a byproduct of burning fossil fuels - in underground storage. Dr. S. Julio Friedmann, Lawrence Livermore National Laboratory held a talk at PARC (Palo Alto Research Center) about this topic on April 12, 2007. Here is a quick summary of his talk:
The carbon capture and
storage is complete mishmash of economic, technological and political
factors. Geological storage of CO2 is the cheapest form of dealing with
pollution from burning fossil fuels.
CO2 capture and storage costs about $30 per ton to store CO2 under the ground, and it can deal with 15-50% of the world's CO2 emission problem..
Prof. Friedman showed several
pictures and charts from a Norwegian oil-platform that has been using CO2
recapture and storage for 10 years. He said there is a $50/ton tax on CO2
emissions, so the Norwegian government is doing the right thing to prompt
the oil company to take action to store the CO2.
There is another large scale
CO2 project running in Sleipner in the Norway sea, Weyburn in Canada and
Algeria (by oil company BP).
Forestation (planning and
growing trees etc) is more expensive that geological CO2
capture/storage. Forestation cost around $50/ton of CO2 capture and
storage.
China builds about 2 new coal
power plants per week, and they are using 1960s technology!!!!
The USA has more than 100 new
coal burning plants ready to be approved and built - as of year 2007 !!!!!
Hydrogen fuel is the cheapest
energy alternative - even when burning fossil fuels to generate hydrogen and
the use of CO2 recapture technology.
Current CO2 technology does not
need any new technology to be invented or proven - and it costs about US $30
per ton of CO2 for capture and storage. Some US companies are talking about
several new technologies that will lower this cost even more.
California has a new law that
stops any power company outside of California to sell electricity to
California without being certified low-emission power plants.
Many good things have started to
take place around the world. Also, California is leading the world
in
technology, political and regulatory framework to deal with CO2 storage and
capture, and it is an excellent export opportunity for California.
You can watch the Prof. Friedmann's video of the entire one hour presentation here: Video: What Organizations has the Most to Gain from Burning Fossil FuelWhat organizations do you think has the most to gain by continuing the trend of burning fossil fuel? ... And, why are the American so interested in maintaining their influence with the Middle East? I hope you can guess the answer: it is "black gold" - also called oil. However, aren't there any alternative fuels? The hydrogen engine has been called the "clean motor." And it certainly is. The only byproduct is water, since the motor only burns hydrogen combined with oxygen gas. We already have the technology to build and use clean engines, but somehow we are still not getting the technology into mass-production. Read an interesting paper by Prof. A. Oppenheim, University of California, Berkeley, who says we can development a clean combustion engine - by "bridging the gap between the progress of science and its engineering implementation". Major auto-makers in no oil producing countries (like Germany and Japan) have already built prototypes. Here are a few pictures of the cars that have been built and are using clean hydrogen fuel - producing zero smog emission. Hydrogen engines are now a real practical science - available as you read this: -
