The weather on our planet is extremely complex. However with the help of super computers, meteorologists and climatologists are learning more and more every day about how our weather system works.
We now have satellites in stationary orbit that watch our planet constantly. These satellites record vasts amount of data and transmit it back to organizations like the National Oceanic and Atmospheric Administration (NOAA). Even with super computers, there are limitations on the amount of data that can be processed. Over time and with the advent of quantum computers, these data processing limitations will disappear. However, I believe the eventual road block will be a lack of long term data.
Imagine having global cloud formation data not just from the past 20-50 years, but from the past million+ years. It could be as simple as a million+ year video of earth from space.
Now play it in fast forward or use an algorithm to search for patterns in cloud movements/formations leading up to major climate changes. Is there a pattern?
Who knows, maybe one day our descendants will look back and wonder why some of us could doubt climate change when the signs were written above us in the clouds for all to see.
