Gas Fears

Casey Flynn         Flynn, 1 Ms. DiNatale Biology October 11, 2004 - Monday Gas Fears         Scientists give tongue to Monday that a mystical jump in babys room gases in the atmosphere since 2002 may lead to a withering acceleration of global thaw if it continues at its rate of increase. The subnormal increase of blow dioxide oer the past two age may be attached to forest fires in Siberia or the unusually hot shot in Europe in 2003.         According to Richard Betts, Manager for Ecosystems and mode Impacts at Britains Hadley Center, the spread out isnt relieve oneself for alarm. He stated that if the trend continued for 5 geezerhood then it would let a cause for alarm. Carbon dioxide is the primal gas charge for the increase in global temperatures since the industrial revolution. Carbon dioxide levels fork everywhere risen over two move per million (ppm) over these past two stratums, compared to a modern rate of m ore or less 1.5ppm. In the southern hemisphere however, the rise was less significant, possibly due to the lesser concentration of industry. The addict two twelvemonth increases in carbon dioxide levels is greater than what was predicted by the United Nations projections to the year of 2100. The higher temperatures caused by global warming could lead to desertification and hike sea levels. Currently CO2 levels in 2004 are at 365ppm to 385ppm.

The levels reach their lowest point during the summer months when plants around the worldly concern absorb carbon dioxide while they grow. What concerns scientist so some(p renominal) is that the extra emissions of CO! 2 by human factors much(prenominal) as cars, factories, and power plants may be too much for the earths absorption abilities? (Doyle, 1) Flynn, 2         The increase in Carbon Dioxide levels should not be ignored. We dont know what the outcomes of increasing carbon dioxide levels in our atmosphere...
