While at first sight that might appear to be the more relevant statistic, it actually is a case like rolling the dice only twelve times: as Emanuel's calculations showed, the number of landfalling storms is simply far too small to get a meaningful result, as those data represent «less than a tenth of a percent of the data for
global hurricanes over their whole lifetimes».
He writes: «the data of landfalling hurricanes in the U.S. is less than a tenth of a percent of the data for
global hurricanes over their whole lifetimes», and shows that from such a small subset of data and given the amount of natural variability, there is no way you would be able to detect a trend by now.

hurricanes (34 %).
They found that averaged sea surface temperatures

over the past half - century: Tsoniset al., 2007); nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age; nor the cessation since 2000 of the previously - observed growth in atmospheric methane concentration (IPCC, 2007); nor the active 2004
hurricane season; nor the inactive subsequent seasons; nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously); nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solankiet al., 2005); nor the consequent surface «
global warming» on Mars, Jupiter, Neptune's largest moon, and even distant Pluto; nor the eerily - continuing 2006 solar minimum; nor the consequent, precipitate decline of ~ 0.8 °C in TS from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.

over the economy through this environmental back - door.
