“USA record lows outpace record highs 19 to 1 this week“. Anthony Watts wants you to think that “snow” (somewhere) equals “cold” (everywhere) and therefore Global Warming is a fraud. His convincing evidence? One week of US data.

In 2009 Gerald Meehl published a report in ScienceDaily that the denialists have tried to undercut ever since titled Record High Temperatures Far Outpace Record Lows Across US. He used 60 years of data.

60 years beats seven days. Source: ScienceDaily.

The last paragraph in Anthony’s post shows that he knows his headline was not only misrepresentative but also only momentarily accurate (italics mine):

*Note: some people clicking on the interactive map will see different numbers, since that map will record new highs and lows as this post ages. The headline was originally based on 16 highs during the week (see the highs map for a ratio of 21 to 1) then by the time the post editing was completed and the post made, the number of highs was up to 18, giving an 18.6 to 1 (~19 to 1 in the title) ratio. Later in the day the number of record highs in the one week period increased as new weather occurred (on Dec 31) and reports came in. The numbers were accurate at the time the post started. Weather records, like weather itself are dynamic with the forward moving one week period the interactive map generator uses, so please don’t assume error if you click on the interactive map and the numbers don’t match now, or in the future. – Anthony
