The effects in one region can be measured at one time, but may have greater effect, less effect or reversed effect in another region at a different time.
That is why prediction is not possible.
Consider Carbon Dioxide: it may increase trapping of the sun’s radiation, causing heating, but the heating increases radiation, causing cooling. Higher carbon dioxide concentrations causes increased plant growth rates, causing cooling, but feeds back to cause lower carbon dioxide concentration causing slower plant growth rates....
No finite set of data can be sufficient.
Trivial predictions are like this: The temperature is now 90 degrees F. The temperature one second from now will be close to 90 degrees F.
Yep... too much stuff going on and at levels lower than the kind of high level data we have can keep track of. If I may use the expression here, “God only knows” what the result will be. Kind of like your proverbial sock except this time both socks are wearing through.
Yep. And in our lives, in our time-mass scale, 10,000 years is one second from now.
