This story from London’s Daily Mail is so bad, the reporter won’t even put his or her name on it.
In the story, we learn the Joplin tornado was caused by global warming. We learn that Katrina was caused by global warming. We learn that droughts are caused by global warming. Floods are caused by global warming. Apparently, every storm or unusual weather phenomena is caused by global warming.
So, lets play ‘climate scientist’ (why not, apparently you don’t have to have any credentials to be one) and take a look at the arguments made in the article.
We’ll start with Hurricane Katrina. Remember how, in the wake of Katrina, we were told that hurricanes were going to be more frequent and more intense? Take, for example, this claim:
The work of hurricane expert Dr. Kerry Emanuel indicates that Global Warming provided the extra margin of energy that gave Hurricane Katrina enough power to break the levees in New Orleans. This is the conclusion of scientists, Global Warming observers along the Gulf Coast and others.
So, what actually happened from 2006 to 2010? The opposite of what was predicted! The five years since Katrina have seen record low hurricane activity — both intensity and numbers! The proof is right here (scroll down from top). The pro-GW crowd got it exactly wrong, again. One would think they would learn some humility, but that never seems to occur.
Second, here is their list of weather events tied to global warming (click to enlarge):
Considering the list encompasses the entire world for 11 years, there isn’t very much here. Nearly half of the years (2001, 2002, 2004, 2007, 2008) don’t have a single occurrence. Considering the warmest year was 1998 (see below) and that temperatures have cooled some since then the list proves northing. As I have stated before, if tornadoes were tied to global temperatures there would have been record tornadoes in 1998. They did not occur.

Here is a graph of carbon dioxide (CO2) concentrations (parts per million) since 1997. It continues to rise.

But, temperatures do not rise with it. If, as the IPCC contends, CO2 is the dominant force driving atmospheric temperatures, then temperatures would have (more or less) risen along with CO2. That simply hasn’t occurred either in the atmosphere or in ocean heat content (the more important metric).
Blaming the Joplin tornado on global warming smacks of desperation. They are losing the scientific argument so they call people names and make ridiculous claims like blaming an individual tornado on global warming. They get away with it because most of the media prints this nonsense generally without question.
