Some people suggest that the increase in global temperatures over time is a serious issue requiring extraordinary action. They point out that average world temperatures have increased 5 since the nineteenth century and that most of this rise has taken place since 1970. They note that this period fits that of the Industrial Revolution, and the temperature rise very closely matches the increase in the amount of 10 CO2 in the atmosphere. They believe that the increase in this gas will lead to raised sea levels floods, and lack water and food. The same people advocate massive reduction in our use fossil fuels in order to cut CO2. However, if we 15 look at the evidence, it is clear to this author that the idea that rising CO2 levels cause a rise in sea levels and other disasters is just another myth First, there is doubt about the extent and cause of this warming. Initial evidence comes 20 from weather stations. However, most of these are in cities, which are warmer than rural areas This explains much of the increase in average temperature. Even if we acknowledge that the world has warmed, this warming is probably 25 part of a natural cycle. The earth naturally warms and cools. At the time of the dinosaurs it was warmer than today, during the last ice age, it was much cooler. In addition, the rise in temperature over the last 200 years has not been 30 constant. Average temperatures fell during the period from 1940 to 1970. If warming is caused by CO2, how can we explain this? On top of that, although there does appear to be a link between
