With the advent of ever more sophisticated devices for measuring temperature, ice extent etc. it becomes ever harder for Climate Change/Global Warming deniers to gain any traction. Lots of interrelated professions are all confirming that the climate of the earth is warming and it is due to the massive dumping of CO2 into the atmosphere. Ice cores, tree rings, CO2 monitors in place on Mauna Loa since the early part of the 20th century etc. show that we are in uncharted waters as far as heat trapping gases in the atmosphere go. The planet is warming and that warming is speeding up Chuck.
