“…it is the change in temperature compared to what we’ve been used to that matters.” – Part 3

In this post, we’re going to present monthly mean TMIN and TMAX Near-Land Surface Air Temperatures (not in anomaly form) for a group of ten (10) Countries in an effort to add a little perspective to global warming. The list … Continue reading

“…it is the change in temperature compared to what we’ve been used to that matters.” – Part 2

In this post, we’re going to present graphs that show the annual lowest TMIN and highest TMAX Near-Land Surface Air Temperatures (not in anomaly form) for ten (10) Countries in an effort to add some perspective to global warming.  The … Continue reading

“…it is the change in temperature compared to what we’ve been used to that matters.” – Part 1

In this post, we’re going to present monthly TMIN and TMAX Near-Land Surface Air Temperature data for the Northern and Southern Hemispheres (not in anomaly form) in an effort to add a little perspective to global warming. And at the … Continue reading

WMO Reasoning behind Two Sets of “Normals” a.k.a. Two Periods of Base Years for Anomalies

Most of us are familiar with the World Meteorological Organization (WMO)-recommended 30-year period for “normals”, which are also used as base years against which anomalies are calculated. Most, but not all, climate-related data are referenced to 30-year periods. Presently the … Continue reading
