re: #396 Liberal Classic

What is nonsense? That water vapor is a greenhouse gas, or that we are releasing carbon from mineral deposits?

Sorry I hit enter too soon, neither of those two statements is wrong, what I am calling nonsense is the idea that mankind’s release of carbon into the atmosphere has a greater effect on climate than mankind’s altering the atmopheric water vapour concentrations though such activities as land use changes, with the biggie (among others) being the cutting down the rain-forests in order to grow cane, which is made into ethanol to replace fossil fuels.
