He’s right of course. The average temperature of the South Pole and Death Valley on July 1 is a meaningless number.
There is no “correct temperature” for the earth because it is always changing.
Well, If at any given simultaneous point in time, temperature readings were recorded for many points at various longitudes and latitudes distributed at regularly spaced intervals, the readings could be summed and then divided by the number of readings. That resultant value would be an approximate average temperature for the whole earth for the specific instant.
In the USA, we have NOAA temperature data stretching back a very long time. That data has high and low values for specific dates at specific stations. Those values can be used to derive an average value for the date. Surprisingly, the average calculated thusly is quite consistent over time. my studies revealed that by calculating an average for say January 5 over a 50 year period and comparing that value with the calculated value for the current year there can be variance. I learned that for the years in question, the average temp for a specific January date was slightly in excess of the historic average.
I actually did all that back in the late 80’s. The result was that for four or five years in a row, the current average value marginally exceeded the historic value.
What that meant to me was that there was no variation in the color patterns of 100+ Wooly Worms correlating to the “warm” weather that year. And, the data thus applied did not show that there was wooly worm color variation in October adequate to predict a warm or cold winter
My questions begin with a statement
I believe in climate change, it has been happening since the beginning of the earth
Then I ask, what is the “normal “ temperature for the earth
What is normal climate
Why did the ice ages come and go without SUVs and coal fired power plants
That’s just my starters, got many more to with that
Like we just left the mini ice age in mid 1800s does it not make sense that temperatures would be rising
