And we should give your opinion equal weight to these guys? American Physical Society "The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now."
Well I don't like the idea of more cooling... but perhaps it will somehow change the pattern which is drought here in California. I am concerned our politicans are going to mis manage this state into a disaster for 30 to 40 million people. We need help from nature because or legislature is so corrupt. as was reported on ET I believe, our almond growers get 3 times more water than Los Angeles. it was alleged they give millions to the the politicans to keep the water turned on.
CO2 is a greenhouse gas. We have raised it's[sic] levels by 40%. It does cause warming. What's under debate is how much warming it causes.
Which produces more CO2, volcanic or human activity? Gas studies at volcanoes worldwide have helped volcanologists tally up a global volcanic CO2 budget in the same way that nations around the globe have cooperated to determine how much CO2 is released by human activity through the burning of fossil fuels. Our studies show that globally, volcanoes on land and under the sea release a total of about 200 million tonnes of CO2 annually. This seems like a huge amount of CO2, but a visit to the U.S. Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC) website (http://cdiac.ornl.gov/) helps anyone armed with a handheld calculator and a high school chemistry text put the volcanic CO2 tally into perspective. Because while 200 million tonnes of CO2 is large, the global fossil fuel CO2 emissions for 2003 tipped the scales at 26.8 billion tonnes. Thus, not only does volcanic CO2 not dwarf that of human activity, it actually comprises less than 1 percent of that value. ------------ ------------ --------------
what a specious point being made by convictbullies Man made co2 is only a tiny fraction of total the natural emissions. so on one hand agw nutters are arguing a small amount of human co2 tips the balance and gets amplified into a disaster...but nature adding more co2 means what? besides the significance of volcanic activity is that most attribute eruptions to cooling.
This much plus about 11% more for the land and air. But CO2 is not the only greenhouse gas. It is estimated that the increased heat gained from the increased GHGs is equal to about 4 Hiroshima bombs per second exploding in the atmosphere. Perhaps 3 of the 4 is due to CO2.
When the scientists start using "Hiroshima bombs" as a unit of measurement, they've drifted out of science and into politics. Of course the sunshine contains energy and it shines all over the earth. So let's put this number in perspective. How many Hiroshima bombs does the sun send to the earth per second? Any physicist can look up the number in a few minutes. The fact that it's not quoted along with the estimate of warming is proof that they're not trying to educate. They're trying to influence elections for their watermelon buddies. Too bad it's failing. The public is less interested in global warming than it's been for a fairly long time. I see the younger (college age) generation all the time. They've had this crap preached to them all their lives. The result is that few of them believe much of it and even fewer modify their behavior according to the desired effect. Back in the glory days of the Soviet Union, the whole population eastern Europe and Russia was forced to listen to Communist propaganda essentially constantly. The result, as usual, was that very few of them believed it.
