Ok, further to my last question, here's the next one...
How much has the amount of CO2 in the atmosphere increased over the last 100 years?
I would like to get a feel for what the average person (who doesn't already know the true figures) thinks the increase in CO2 in the atmosphere is.
Let us assume for simplicity that there were 100 "units" of CO2 100 years ago. How many are there today? So if you think it's still the same, you would say 100. If you think it's increased by 1% you'd say 101. 10% = 110, if you think it's inceased 10 times, you'd say 1000, etc.
So, what do you think?
Please, please, please, if you know the answer, or have looked it up, don't post the true figure here.
