Myth #2: The Medieval Warming Period was at least as warm as the current global temperature.
Myth #3: The reason people think global warming is happening is because of the “hockey stick” graph, which is completely inaccurate.
Myth #4: The Earth is getting warmer because the Sun is getting warmer.
Myth #5: The global mean surface temperature actually decreased between 1940 and 1970, so that means CO2 emissions have nothing to do with global warming.
Myth #6: It’s only a few degrees warmer; that’s not a big catastrophe, is it?
Myth #7: The interior of Antarctica has shown an overall cooling trend in recent years, and there has been a larger than normal amount of snowfall that has actually been increasing the amount of Antarctic snow and ice. If ice mass in Antarctica is increasing, that in itself disproves global warming.
Myth #8: Global warming is caused by natural phenomena on Earth such as volcanoes and trees, not by human activity.
Myth #9: The thermometer record is skewed by the Urban Heat Island effect – because most of the world’s thermometers are in cities, and cities are disproportionately warm compared to the surrounding countryside, that is the explanation for global warming.
Myth #10: We shouldn’t base political and economic decisions on some unreliable “computer modeling” because global warming is too uncertain, the risk to our economy too great.
These myths about global warming have been answered beyond any shadow of a doubt to be false. Suggesting one of these as a reason to doubt global warming puts you in the same category as those who claim that the destruction of the World Trade centers was not an act of terrorism, but a desperate act on the part of the Bush administration.
