Earth has 17 climates not ONE ,LOL
But I think the point the author is trying to make is that such an average may not provide much insight into what is really happening. It also may not even reflect reality in a situation where the data is very noisy, and the system you are interested in may not be well represented by the chosen sample locations.
As one example of the challenges involved, if you had a network of 100 temperature sensors, the average over 1 year could move up by one degree if the average temperature at each of the sensors increased by one degree during every day of the year, or if the temperature increased at ten of the sensors by 10 degrees during every day of the year, or if the temperature increased by 10 degrees at ten of the sensors randomly, with a given sensor changing by 10 degrees for about a month per year.
In each case the effects of the temperature changes would be different. But the average is the same.
Given the wide variance in temperatures measured locally, and during the course of each day, small shifts in the average may or may not represent significant changes.
The people arguing that climate change is a pressing danger need to show not just a small change in the average, but a change in weather dynamics, or the concentration of the change in an area where it will make a difference.
In most places in the USA a 1 degree shift in average temperature can result from driving a short distance. In New England it might be the next town over. That kind of local change does not create significant changes in ordinary life.
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
Yes; temperatures are estimated from the study of tree rings. Older studies were based upon tree rings manually extracted from the trees which included the possibility of the rings being compacted or elongated from the process. Jan Esper instead used ultra high definition x-rays which allowed the rings to be studied down to the molecular level.
While it is impossible to determine what the temperature was on a given day and a given year it is possible to estimate the relative temperature of a given year relative to past and present years.
Given that political activists masquerading as scientists are attempting to force their theories of man-made global warming down our throats, as an excuse to impose their marxist agenda, we can use science to counter their absurd claims.
