The so-called "hockey stick" graph (courtesy of Wikipedia; created by Robert A. Rohde using public data; ref. source for legend). While this common image itself does not appear in the IPCC's recent Summary for Policy Makers based on the Fourth Assessment Report, the theory that the current global average temperature is the highest it has been in roughly 1,300 years has been upheld by the National Academy of the Sciences and is clearly stated in the IPCC SPM.
Human Events hopes to undermine climate science by spreading their own myths. Color me shocked. No actual science publication supports these claims but of course that doesn't stop a conservative political magazine from publishing them. However, since someone has to set the record straight, I might as well try.
Global warming means more frequent, more severe storms. – It certainly may, as is pointed out in the IPCC's Fourth Assessment. From the SPM:
Based on a range of models, it is likely [greater than 66% confidence] that future tropical cyclones (typhoons and hurricanes) will become more intense, with larger peak wind speeds and more heavy precipitation associated with ongoing increases of tropical SSTs.
Oh, did I just quote that from where they said I couldn't? That's odd.
Climate was stable until man came along. – Who even says that? Of course climate changes. The problem is that is currently changing at a rate an entire order of magnitude faster than previously known. Further, we are now most likely warmer than any time in the previous 1,300 years. Oh, the so-called "hockey stick" graph? It's still in the IPCC report, just in written format (sorry, but you have to read and not just look at pretty pictures):
Paleoclimatic studies use changes in climatically sensitive indicators to infer past changes in global climate on time scales ranging from decades to millions of years. Such proxy data (e.g., tree ring width) may be influenced by both local temperature and other factors such as precipitation, and are often representative of particular seasons rather than full years. Studies since the TAR draw increased confidence from additional data showing coherent behaviour across multiple indicators in different parts of the world. However, uncertainties generally increase with time into the past due to increasingly limited spatial coverage. Paleoclimate information supports the interpretation that the warmth of the last half century is unusual in at least the previous 1300 years. … Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1300 years.
The notion that the "hockey stick" graph is wrong was proven false last summer when the National Academy of the Sciences determined that it was in fact, correct. Too had Human Events doesn't bother to read the news. Then again, it's not like paleoclimate is the only reason that we know global warming is happening.
