I asked three random people (well it’s about as scientific as those polls in the Courier-Mail) some simple questions.
Do you believe the world is getting warmer as a result of human action? Two said yes, one no.
To the two who said yes: ‘What are we doing that is causing the world to get warmer?’
They both answered that we are making too much carbon dioxide, and this is trapping sunlight.
Next question: ‘If you had a box containg 10,000 air particles, how many of them would be carbon dioxide?’
One answer: Half?
The other answer: About 3,000?
My response. ‘Three.’
‘What, three thousand?’
‘You mean 300?’
‘That can’t be right.’
“Go and check it out.’
‘No that can’t be right.’
Ahh, the joyful bliss of ignorance.
Except that, in this case, and often, ignorance does not promote bliss, but uneccessary panic.
There is vastly more water vapour in the air than CO2, and water vapour is a more effective retainer of heat.
The minimal effect of that tiny amount of CO2 is simply swamped by other factors including water vapor.
The even more minimal additional amount of CO2 resulting from human activity causes so little change that it cannot even be measured.
Despite this, everywhere is getting hotter faster than everywhere else, and Mars is getting hotter fastest of all. And it’s all our fault. Except Mars.
Gol darn those irresponsible truck driving martians!
Of course, scientists keep saying we should stop panicking about climate because we can’t do anything about it anyway, and get on with solving real problems, but I still think those martians need to be taught a lesson.
