Ocean acidification, caused by absorbtion of Carbon Dioxide, will decimate seafood supply, affecting coastal community economies as well as diminishing overall food supplies for the growing population, which we are already seeing the effects of. (globalclimatescam.com)
Hi Chris, The feedback effect decreases as the CO2 concentration increases as absorbtion bands become saturated. (illconsidered.blogspot.ru)
An increase in the sun's irradiance such as occurs over the 11 - year sunspot cycle (or potentially longer time scales) warms the stratosphere (due to increased absorbtion by ozone) but it also warms the troposphere. (realclimate.org)
