The Sun has been doing strange things for a long time.
The problem with Religious Science. This is proveable truth forever and for all time! When change is discovered it is called a Cycle, or syndrom.
Quantum Mechanics is based on behavior change when a system gains or loses energy.
Change is the system. Long before farts were blamed for climate change, the climate changed. Ice Ages come and go, periods warmer than today, and the cause had to be outside this planet.
Carbon 14 dates do not fit the known dated periods, tree rings, Carbon 14 wanders. Production varies over time.
The Sun eats, excreats, blasts out Solar Flares, and absorbs a lot of cosmic radiation. Input/output must vary.
Careful measurement has shown the speed of light to be a constant, as measured on the surface of the earth. Time is also a constant, on Earth.
No one has been around long enough to measure decay rates, Like Carbon 14 they could wander a bit over time. An ice age could slow it, a supernova speed it up.
Water evaporates, slower at higher air pressure, humid air, higher with heat, Processes vary with the background.
This Earth Centric thinking clouds our vision of the whole system.
The view that climate is a measured standard only counts the last few hundred years, and ignores the last 25,000 which had a large and long ice age, sea level down 150 meters, and a period much warmer with sea level seven meters higher. That energy change did not come from the planet.
Longer term the age of dinosaurs that just ended was 125 degrees for over a hundred million years. A warmer sun seems likely, more than dinos breaking wind.
Expect change.
