Frequency Of Hot Days In The US Have Declined Sharply Over The Last Century

Steven Goddard has constructed a time series on the frequency of hot days over 100 deg F and 90 deg F since 1910 and finds a downward trend. Steve didn’t give a commentary and leaves you to ponder

Real Science

The frequency of 100 degree temperature readings in the US is down almost 50% over the past century, measured at all GHCN HCN stations.

  1. the days/nights temp overall is not cooler, or warmer now than 100y ago!

    because for the last 100y people built lots of dams + irrigation increased = extra moisture in the air/ topsoil moisture and water storages. What that does is: days are a bit cooler / BUT nights are a bit warmer = overall temp is always the same. It does show difference, because: they are monitoring only THE HOTTEST MINUTE in 24h and skilfully ignore the other 1439 minutes in the 24h even though they don’t change accordingly as the hottest minute. in other words: Warmist & Skeptics mislead each other with shonky data collection: http://globalwarmingdenier.wordpress.com/climate/
