Course offered at Energy-Ingenuity where we discuss "unseen things", N. Tesla. Some of these things don't have names yet and some do.
Is "Climate Change or Global Warming" demonstrated by a change in the thermometer? We did not use "Carbon" to cause this change in the temperature. It was not "Wardforce", which is another unseen, that has caused this change in the thermometer.
Climate change could be defined by duplicating a change. Global temperatures demonstrate Climate change and it has been blamed, Carbon and a host of other things. This is the only test, that I am aware of, which demonstrates climate change.
The real change is in the thermometer and what has caused this change. A Galileo thermometer demonstrates Earth's atmasphere, Gravity and Anti Gravity. What if ...? Do you see where this is going?
