STILL with this ridiculous assertion???
OK then, let's take a look at it using the data YOU provided.
First your graph. Yep, there is a horizontal line that is higher on the left than it is on the right showing a decreasing trend. No argument there. But the line is an Excel feature based on the data points and when you look at them the decrease isn't quite as obvious. Sure, the 2022 point is lower than the 2016 point but the 2022 point shows an increase over last year and an overall increase over 2015 start of the period.
Then why does Excel show a decreasing trend? Because the 2016 point is significantly higher than it's neighbors. If you cherry-pick a starting point then you can often show whatever you want.
What is MOST interesting about this, and quite ironic, is that the cooling trend you are so excited about only exists because of an extremely warm year!
Now on to the second graph where I "cherry-picked" a point 23 years ago. (If you don't like 22 then pick 50 or 10 or 17 or 42 or whatever number you like greater than 7) On this graph there is a horizontal(ish) line that is lower on the left and higher on the right showing a warming trend. What we can also see in this graph is that except for four extremely warm years, 2022 was the warmest in the last 23 years. If you remove the 2022 data then 2021 was the warmest in the last 22 years.
This is *your* chosen data just not your chosen starting point.
Of course, none of this speaks to whether man has anything to do with the warming. This only shows that the cooling trend that you continue to assert does not exist or rather, it exists only because of a set of unusually warm years.
