CO2 - the numbers don't stack up

CO2sceptics News Blog | Analytical Chemist: Numbers don't add up for global warming

Our greatest greenhouse gas is water. Atmospheric spectroscopy reveals why water has a 95 percent and CO2 a 3.6 percent contribution to the "greenhouse effect."

Carbon dioxide emissions worldwide each year total 3.2 billion tons. That equals about 0.0168 percent of the atmosphere's CO2 concentration of about 19 trillion tons. This results in a 0.00064 percent increase in the absorption of the sun's radiation. This is an insignificantly small number. The yearly increase is many orders of magnitude smaller than the standard deviation errors for CO2 concentration measurement.

"Scientific" computer simulations predict global warming based on increased greenhouse gas emissions over time. However, without water's contribution taken into account they omit the largest greenhouse gas from their equations.

How can such egregious calculation errors be so blatantly ignored? This is why man-made global warming is "junk" science.

Some numbers there I haven't seen, or been able to find, before...


I've occasionally wondered how scientists come up with Carbon Dioxide emissions figures in the first place. I can't imagine it's an easy thing to measure directly as it is produced, so is it worked out backwards?

e.g. Measure at Mauna Loa (why only one place?) take a good guess at how much is naturally produced and then apportion the rest according to some formula or proxy for carbon emissions.(GDP perhaps)

Dear me, Englishman - usually you're spot on with your thinking.

I think you'll find that there have been over 54 major volcanic eruptions (Excluding Mauna Loa) worldwide from January 1st 2008 to 26th September 2008. Most of these don't get reported except on the local news, or if it's a really big one.

Think about all those volcanoes pumping ash plumes, CO2, SO2, and a range of other gases and particulate matter sometimes over 8km into the atmosphere. Rather dwarfs human output.
