Hi All, I am all for saving the world (or for trying to slow down the constant changing of the planet). Like all of us I am also very much concerned about the ever warming climate and the probable results of that.
The "carbon footprint" of things seems to be the biggest single cause of the problem. The "brainwashers" of this world have pretty much succeeded in making us belief that it is the "human carbon footprint" which is the main culprit for global warming especially the use of crude oil (fossil fuel) - but is it really ?
Yes, it is.
The world currently use about 90 million barrels of crude a day which is about 0.0143 cubic kilometers of oil a day x 3 (the scientists say that burning one barrel of crude produces about 3 times the amount of CO2) x 365 (days in a year) x 160 years (that's about how long humans have used crude oil in large quantities) = approx 2,500 cubic kilometers of CO2 produced by all the crude used over the last 160 years by us humans - it is probably much less as we did not consumed 90 million barrels a day right from the start but slowly buid up to that quantity over the 160 years.
You cannot use liquid volume instead of mass for such a calculation.
The newspapers have reported that the volcanic outburst a while ago that caused so much problems for the airlines, has spewed more than 20,000 cubic kilometers of CO2 into the atmosphere in just 6 days - that is 8 times more than all the crude released over 160 years did!
No, that is wrong.http://hvo.wr.usgs.gov/volcanowatch/2007/07_02_15.htmlGas 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.
I think that the amount of CO2 released into the atmosphere by all the volcanic eruptions over the last 160 years is vastly more than that of all the crude used over the same period.
The data does not support this conclusion.
I have read that the amount of CO2 released annually by veld fires around the world is also much more that released by crude in the same year.
I would question your reading material, but moreso the understandign of the carbon cycle.http://en.wikipedia.org/wiki/Wildfire
Forest fires in Indonesia in 1997 were estimated to have released between 0.81 and 2.57 gigatonnes (0.89 and 2.83 billion short tons) of CO2 into the atmosphere, which is between 13%–40% of the annual carbon dioxide emissions from burning fossil fuels.
The amount of CO2 exhaled per year by the 7 billion people on earth (not even taking the animals into account) is more than the amount of CO2 released per year by burning crude!
Again the lack of understanding of the difference between carbon within the carboen cycle and sequestered carbon being released is significant.
Crude oil probably contributed less than 1 part in 2,000,000 towards the total CO2 being released into our atmosphere over the last 160 years.
No, not the amount being released, but you are confused over what is released into the cycle and what is moving within that cycle.
