1920 or 2020? Kerang Australia Edition

24 Nov 2021 | 1920 or 2020, Science Notes

The town of Kerang is midway between Adelaide and Canberra in Victoria, Australia, so if you find yourself driving through it be sure to stop and offer your sympathies to the locals who are enduring the ravages of the climate emergency. To demonstrate how much you understand their plight, you could show them the chart below which contrasts crisis-level 2020 daily temperatures in Kerang to those in cool, comfortable 1920 so starkly that surely we don’t need to label the curves. But just in case you can’t tell the difference for some reason, see below for the answer.

Here it is:

If you had to peek at the answer to be sure, it just goes to prove that the changes are so small you probably wouldn’t have noticed them if you’d been alive and paying attention in Kerang during both years.

  1. The shy is falling! The sky is falling! And, there's a wolf! A wolf! And, and, and .... The world is melting! It is about to burst into flames!


  2. It seems strange to even talk of 'average global temperature' as a meaningful thing --for example when it is mid summer in ,say, Alice Springs , Australia it might be +40 degrees C - same day in Moscow it is minus 40 degrees (C) --ergo 'average temp" equals ZERO degrees --- months later in Alice Springs ,temp is +20 degrees C -and in Moscow it is -20 degrees -- average temperature still ZERO . If there was an even gradient of temps between polar opposite pairs of cities the grand average might still 'average out' to the expected temperatures related to latitude mainly so what significance has this 'average temperature ' got -almost NOWHERE is 'average' at any time and since absolute temperatures start from _273 degrees C the variations around the freezing point of water seem even less meaningful.
