With the annual United Nations Climate Change Conference now underway in Azerbaijan, we are again being bombarded with doom-and-gloom climate alarmism. Perhaps the silliest and least substantiated is the latest assertion that the rate of warming today is greater than at any time in history.
Climate sensationalists must have realized that the rise in the so-called global average temperature was not seriously concerning most people. After all, the total amount of “global warming” since 1880, namely in the past 144 years, is, according to the UN and governments worldwide, about 1.2 degrees Celsius. That amount is so small that it would not even be noticeable in a single human lifetime.

Even though the rise may look dramatic on a graph with a vertical axis graduated in tenths of a degree like the first figure below, it was only a matter of time before someone pointed out that if you plot the same data on a graph with the range being that which we experience in everyday living, the change is barely noticeable (see second graph below, an X posting by Greenpeace co-founder Dr. Patrick Moore).
So, just as alarmists changed the narrative from global warming to climate change when warming stopped early this century, they now try to scare us about something new – the RATE of warming. Oh, my.
So, we are now told by reports such as the second annual Indicators of Global Climate Change report, which is led by the University of Leeds, that last year, the rate of warming hit 0.26 degrees Celsius per decade — up from 0.25 degrees Celsius, the year before. In other words, they tell us that the rate of warming has risen ONE ONE-HUNDREDTHS of a degree per decade in one year. According to NASA’s Goddard Institute for Space Studies (GISS), the current uncertainty in global temperature measurements is about 0.05°C for recent years. So, the rate of warming per decade has increased by only one-fifth of the uncertainty in the measure of temperature used to calculate the rate, meaning that this so-called increase is insignificant, something the researchers actually admit. Take a look at the first graph above – can you see any increase in the rate of warming since 1980? Of course not. No one can even see hundredths of a degree per decade change in the rates of warming.
