I am grateful to Greenman3610, who regularly posts videos about the science of Global Warming on his YouTube channel. He listens to the arguments made on both sides and balances the evidence. There is still a great deal of public denial that a problem is developing but the overwhelming weight of the evidence suggests that the planet is warming, and that human activity is responsible. We can’t do a controlled experiement to demonstrate it in the classical scientific way because you would need two identical planets and total global control over both of them. But it is still scientific to collect evidence and draw conclusions.

Questions…
- Carbon dioxide is a natural part of the atmosphere. What natural processes add & subtract carbon dioxide from the air?
- Water is also a ‘greenhouse’ gas but the ever changing levels of water vapour in the air are not causing ‘climate change’. How come water vapour isn’t a problem but CO2 and methane are? [Might require some research!]
- What is the current best estimate for the average CO2 % or concentration (parts per million) of the air?
- What is a simple way to convert farenheit into celsius?
