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 list of countries, which follows, includes the countries with the highest populations.

And, as always with my posts, as part of the text, there are hyperlinks to the data that were used to prepare the graphs. Just click on the links if you’re looking for the data. 

INITIAL NOTES

First of all, TMIN is described by Berkeley Earth as the “Mean of Daily Low Temperatures”, while TMAX is described as the “Mean of Daily High Temperatures”. Berkeley Earth provides monthly TMIN and TMAX data until partway through 2013. The start month for these individual-country datasets at Berkeley Earth depends on data availability from the individual country. Sometimes they start in the early 1800s, maybe even the mid-to-late 1700s for countries to be included in future posts (like the United Kingdom), and other times they start in the mid-to-late 1800s, so I’ve chosen 1900 as the start year for this post. The year 1900 is the end year of the IPCC’s new definition of “pre-industrial” times, so starting the graphs in 1900 is also appropriate in that respect.
