Professor Emeritus of Geology at Western Washington University, Don J. Easterbrook , discussed the causes of climate change and glacial fluctuations, the 500-year record of temperature changes using data from the Greenland ice core, the supposed effect of CO2 on climate change, and the geologic history of climate change. Rather than being in the midst of global warming, “we’ve never really left what’s been known as the Little Ice Age, which was a global cooling that took place about 1300 AD,” and has continued with a series of fluctuating climates of cold to warm, he remarked, adding that the sun is approaching a solar minimum that is similar to when the Little Ice Age first started.

Looking at the patterns of changes in the ocean associated with warming and cooling, he found a cycle that repeats over 60-year periods and was able to correlate these findings with the Greenland ice core. Easterbrook commented that Arctic sea ice is actually growing, and that the global warming scare is based on politics rather than science. Regarding rising sea levels, records that go back to the 1800s show that there’s a rise of about 7 inches per year and that’s been pretty much constant regardless of what the climate is doing, “so the idea that we’re going to be having 20 ft. sea level changes is just not credible,” he argued. Further, in contrast to the consensus of most scientists, the evidence actually suggests that C02 does not cause global warming, Easterbrook continued, adding that some 32,000 American scientists agree with him on this point.
