Atmospheric co2 concentration effects on rice water use and biomass production.

2011 ). No glacial inception is projected to occur at the current atmospheric CO 2 concentrations of 390 ppmv (ref. 1).Indeed, model experiments suggest that in the current orbital configuration—which is characterized by a weak minimum in summer insolation—glacial inception would require CO 2 concentrations below preindustrial levels of 280 ppmv (refs 2, 3, 4).

Today CO 2 concentrations hover at 410 ppmv, a 30 percent increase since 1959 and a 49 percent increase from 1750, the time just before the start of the Industrial Revolution (when CO 2 concentrations were likely Posts about Population written by Bob. Our planet is surrounded by an incredibly thin envelope of gasses. The part that allows all life to exist is a mere 25,000 feet or a little over 8 kilometres deep – if we go any any higher than this man, and almost all other animals on this planet, suffers from hypoxia and fails to stay alive (without artificial means).

This projection is the average of 10 global climate models using the IPCC’s A1B emissions scenario. A1B is a middle-level scenario for both carbon dioxide emissions and economic growth, with carbon dioxide levels rising from 390 ppmv at present to 550 ppvm by the mid-2050s.
