http://globalwarming.sdsu.edu/17. The concentration of carbon dioxide in the atmosphere increased gradually from a low of 190 ppm 21,000 year ago, to about 290 ppm in the year 1900, i.e., at an average rate of 0.00478 ppm per year.
18. The industrial revolution, where humans developed machines (artificial animals, since they consume fuels, which are mostly organic matter), began in England about 240 years ago (1767).
25. The concentration of carbon dioxide in the atmosphere, which was at 290 ppm in the year 1900, rose to 316 ppm in 1959, or at an average 0.44 ppm per year.
26. Measurements of the concentration of carbon dioxide since 1959 (316 ppm) have revealed an increase to 388 ppm in 2010, or at an average 1.41 ppm per year.
27. The concentration of carbon dioxide has increased an average of about 1.8 ppm per year over the past two decades.
28. The concentration of carbon dioxide increased 2.87 ppm in 1997-98, more than in any other year of record.
29. The year 1998 was the warmest of record. The year 2002 was the second warmest (to that date). The year 2003 was the third warmest (to that date). The year 2004 was the fourth warmest (to that date). The year 2005 equaled 1998 as the warmest of record. The year 2007 equaled 1998 as the second warmest of record. The ten warmest years have occurred in the twelve-year period 1997-2008.
30. About 75% of the annual increase in atmospheric carbon dioxide is due to the burning of fossil fuels.
It is my opinion that the current minority of people who refuse to accept the proven data about global warming base their views purly on ideology. It is pretty much the same as those who didn't believe in the moon landing, believed the Earth was flat, believe that the world is only 6000 years old and the was created in 6 days, that the Sun, planets and stars revolve around the Earth, believe in Creationism instead of evolution and every other misbelief and misconception that has been proven false with science. Why there are a very small minority of people who deny proven scienctific fact and technology because of idealogical lines instead of physical evidence. Burn the witch.....
