Well the weather was kind enough today for me enjoy a nice bimble
Its all swings and roundabouts ;) I get alot of paperwork comethrough the office here on theories, studys, technologies relating to global warming and reducing C02 both for and against (a lot of it is never discussed in the media). There is no doubt reducing the human contribution of C02 is a good thing but C02 from human activity is not the primary reason the plant is warming. All throughout history there are large periods of time where facotors not relating to human activities have increased and reduced C02, methane, nitros oxide etc.Quote:

“All Lies”? Or are we in denial because the truth on global warming is too painful to face up to?
The survey of the world’s scientific community featured in the following extracts from the ‘Science daily’ publication article in 2009 is probably the most comprehensive of its kind ever carried out. Although completed some time ago it is still very much relevant to the debate on this thread.
A group of 3,146 earth scientists surveyed around the world overwhelmingly agree that in the past 200-plus years, mean global temperatures have been rising, and that human activity is a significant contributing factor in changing mean global temperatures.
Peter Doran, University of Illinois at Chicago associate professor of earth and environmental sciences, along with former graduate student Maggie Kendall Zimmerman, conducted the survey late last year.
The findings appear January 19 in the publication Eos, Transactions, American Geophysical Union.
In trying to overcome criticism of earlier attempts to gauge the view of earth scientists on global warming and the human impact factor, Doran and Kendall Zimmerman sought the opinion of the most complete list of earth scientists they could find, contacting more than 10,200 experts around the world listed in the 2007 edition of the American Geological Institute's Directory of Geoscience Departments.
Experts in academia and government research centres were e-mailed invitations to participate in the on-line poll conducted by the website questionpro.com. Only those invited could participate and computer IP addresses of participants were recorded and used to prevent repeat voting. Questions used were reviewed by a polling expert who checked for bias in phrasing, such as suggesting an answer by the way a question was worded. The nine-question survey was short, taking just a few minutes to complete.
Two questions were key: have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures.
About 90 percent of the scientists agreed with the first question and 82 percent the second.
In analyzing responses by sub-groups, Doran found that climatologists who are active in research showed the strongest consensus on the causes of global warming, with 97 percent agreeing humans play a role. Petroleum geologists and meteorologists were among the biggest doubters, with only 47 and 64 percent respectively believing in human involvement. Doran compared their responses to a recent poll showing only 58 percent of the public thinks human activity contributes to global warming.
"The petroleum geologist response is not too surprising, but the meteorologists' is very interesting," he said. "Most members of the public think meteorologists know climate, but most of them actually study very short-term phenomenon."
He was not surprised, however, by the near-unanimous agreement by climatologists.
"They're the ones who study and publish on climate science. So I guess the take-home message is, the more you know about the field of climate science, the more you're likely to believe in global warming and humankind's contribution to it."
For the sake of future generations, let’s hope the experts have got it wrong.
Apologies for the long post, but a very complex issue.
It's just an excuse to add more taxes. Just a big scam.
Weather is changing but it's not because of us. The whole debate about Co2 is a joke ;D
http://www.globalclimatescam.com/
"CO2 is not a pollutant. In simple terms, CO2 is plant food. The green world we see around us would disappear if not for atmospheric CO2. These plants largely evolved at a time when the atmospheric CO2 concentration was many times what it is today. Indeed, numerous studies indicate the present biosphere is being invigorated by the human-induced rise of CO2. In and of itself, therefore, the increasing concentration of CO2 does not pose a toxic risk to the planet." - John R. Christy, Ph.D. Professor of Atmospheric Sciences, University of Alabama
"Carbon dioxide is not a pollutant but a naturally occurring, beneficial trace gas in the atmosphere. For the past few million years, the Earth has existed in a state of relative carbon dioxide starvation compared with earlier periods. There is no empirical evidence that levels double or even triple those of today will be harmful, climatically or otherwise. As a vital element in plant photosynthesis, carbon dioxide is the basis of the planetary food chain - literally the staff of life. Its increase in the atmosphere leads mainly to the greening of the planet. To label carbon dioxide a "pollutant" is an abuse of language, logic and science." - Robert M. Carter, Ph.D. Professor of Environmental and Earth Sciences, James Cook University
"Carbon dioxide is not a pollutant. On the contrary, it makes crops and forests grow faster. Economic analysis has demonstrated that more CO2 and a warmer climate will raise GNP and therefore average income. It's axiomatic that bureaucracies always want to expand their scope of operations. This is especially true of EPA, which is primarily a regulatory agency. As air and water pollution disappear as prime issues, as acid rain and stratospheric-ozone depletion fade from public view, climate change seems like the best growth area for regulators. It has the additional glamour of being international and therefore appeals to those who favor world governance over national sovereignty. Therefore, labeling carbon dioxide, the product of fossil-fuel burning, as a pollutant has a high priority for EPA as a first step in that direction." - S. Fred Singer, Ph.D. Professor Emeritus of Environmental Sciences, University of Virginia
"To state in public that carbon dioxide is a pollutant is a public advertisement of a lack of basic school child science. Pollution kills, carbon dioxide leads to the thriving of life on Earth and increased biodiversity. Carbon dioxide is actually plant food." - Ian R. Plimer, Ph.D. Professor Emeritus of Earth Sciences, University of Melbourne
"Carbon and CO2 (carbon dioxide) are fundamental for all life on Earth. CO2 is a colorless, odorless, non-toxic gas. CO2 is product of our breathing, and is used in numerous common applications like fire extinguishers, baking soda, carbonated drinks, life jackets, cooling agent, etc. Plants' photosynthesis consume CO2 from the air when the plants make their carbohydrates, which bring the CO2 back to the air again when the plants rot or are being burned." - Tom V. Segalstad, Ph.D. Professor of Environmental Geology, University of Oslo
"To suddenly label CO2 as a "pollutant" is a disservice to a gas that has played an enormous role in the development and sustainability of all life on this wonderful Earth. Mother Earth has clearly ruled that CO2 is not a pollutant." - Robert C. Balling Jr., Ph.D. Professor of Climatology, Arizona State University
"C02 is not a pollutant as Gore infers. It is, in fact essential to life on the planet. Without it there are no plants, therefore no oxygen and no life. At 385 ppm current levels the plants are undernourished. The geologic evidence shows an average level of 1000 ppm over 600 million years. Research shows plants function most efficiently at 1000-2000 ppm. Commercial greenhouses use the information and are pumping C02 to these levels and achieve four times the yield with educed water use. At 200 ppm, the plants suffer seriously and at 150 ppm, they begin to die. So if Gore achieves his goal of reducing C02 he will destroy the planet." - Tim F. Ball, Ph.D. Climatology
"Many chemicals are absolutely necessary for humans to live, for instance oxygen. Just as necessary, human metabolism produces by-products that are exhaled, like carbon dioxide and water vapor. So, the production of carbon dioxide is necessary, on the most basic level, for humans to survive. The carbon dioxide that is emitted as part of a wide variety of natural processes is, in turn, necessary for vegetation to live. It turns out that most vegetation is somewhat 'starved' for carbon dioxide, as experiments have shown that a wide variety of plants grow faster, and are more drought tolerant, in the presence of doubled carbon dioxide concentrations. Fertilization of the global atmosphere with the extra CO2 that mankind's activities have emitted in the last century is believed to have helped increase agricultural productivity. In short, carbon dioxide is a natural part of our environment, necessary for life, both as 'food' and as a by-product." - Roy Spencer, Ph.D. Meteorology, Former Senior Scientist for Climate Studies, NASA
My personal view is that there's no doubt whatsoever that everything we've been shoving into the atmosphere ever since the industrial revolution has to have had an effect. Now with over 6 billion people on the planet and with China, the US and most other countries adding enormous quantities of pollutants into the atmosphere I'm struggling to think how that can be a good thing. And if its not a good thing then it has to be a bad thing. It is tremendously complicated issue - far more difficult to predict than the weather patterns for the coming week. And they don't get that right either.
And now they're all jumping on the bandwagon to reach the new Arctic oil and gas fields being exposed as the ice is melting. Forget the jetstream, its when the Gulf stream stops that we in the UK will really be in trouble. Its all our own fault though as we provide the demand for the oil exploration and then pump the air with the nasty stuff.
Its very complicated though - way beyond my intellect to understand.
"I am at a loss to understand why anyone would regard carbon dioxide as a pollutant. Carbon dioxide, a natural gas produced by human respiration, is a plant nutrient that is beneficial both for people and for the natural environment. It promotes plant growth and reforestation. Faster-growing trees mean lower housing costs for consumers and more habitat for wild species. Higher agricultural yields from carbon dioxide fertilization will result in lower food prices and will facilitate conservation by limiting the need to convert wild areas to arable land." - David Deming, Ph.D. Professor of Geology and Geophysics, University of Oklahoma
"Carbon dioxide is not a pollutant. It is a colorless, odorless trace gas that actually sustains life on this planet. Consider the simple dynamics of human energy acquisition, which occurs daily across the globe. We eat plants directly, or we consume animals that have fed upon plants, to obtain the energy we need. But where do plants get their energy? Plants produce their own energy during a process called photosynthesis, which uses sunlight to combine water and carbon dioxide into sugars for supporting overall growth and development. Hence, CO2 is the primary raw material that plants depend upon for their existence. Because plants reside beneath animals (including humans) on the food chain, their healthy existence ultimately determines our own. Carbon dioxide can hardly be labeled a pollutant, for it is the basic substrate that allows life to persist on Earth." - Keith E. Idso, Ph.D. Botany
"To classify carbon dioxide as a pollutant is thus nothing short of scientific chicanery, for reasons that have nothing to do with science, but based purely on the pseudo-science so eagerly practiced by academia across the world in order to keep their funding sources open to the governmental decrees, which are in turn based on totally false IPCC dogma (yes, dogma - not science)." - Hans Schreuder, Analytical Chemist
"Atmospheric CO2 is required for life by both plants and animals. It is the sole source of carbon in all of the protein, carbohydrate, fat, and other organic molecules of which living things are constructed. Plants extract carbon from atmospheric CO2 and are thereby fertilized. Animals obtain their carbon from plants. Without atmospheric CO2, none of the life we see on Earth would exist. Water, oxygen, and carbon dioxide are the three most important substances that make life possible. They are surely not environmental pollutants." - Arthur B. Robinson, Ph.D. Professor of Chemistry

Carbon Dioxide is a natural occuring gas and without it we would not be here. However, thats in its natural balance. Too much CO2 is a bad thing. Watch the Apollo 13 film for a real life example of why too much CO2 is a bad thing to animals including us that breath air. There needs to be a natural balance on this planet - when the balance is lost there's too much or too little of those things that when balanced give us life. And since we're dismantling the rain forests where CO2 is converted to oxygen we're getting too much CO2 in the atmosphere. IMHO of course..... ;)
I'm just waiting for some bright spark to state that there's not enough Carbon Monoxide in the air......... a major byproduct of combustion engines.
Don't worry the planet will carry on nicely without humans on it :)
