Many people are concerned that man-made global warming is causing sea levels to rise and threatening coastal communities. But are these concerns justified? Well not according to Dr. Patrick Michaels, author of the new book Climate of Extremes, who has this to say: “We have two ways of measuring sea levels. We can do it with tide gauges along coastal regions or we can do it with satellites. Both of these records tend to show in general that sea level rise has been fairly constant – obviously the satellite record is much shorter. Interestingly, as the planetary warming stopped in the late 1990’s, and we’ve actually had some cooling, the satellite appears to indicate a slight reduction in the rate of sea-level rise, not an increase.”
