...just one of several studies by NASA. I could cite a bunch more but my sister, a PHD global warming tree hugger, contributed to part of this study (she works for USGS) and has since changed her mind regarding "anthropogenic greenhouse gases" being the primary cause of "climate change". Here are some highlights:<br> <br> -The 1997 Kyoto Protocol, which calls for industrialized nations to reduce their CO2 emissions to 95% of 1990 levels by 2012 is itself considered a difficult target to achieve.<br> <br> -Climate simulations lead to the conclusion that the Kyoto reductions will have little effect in the 21st century.<br> <br> ...global warming has been caused mainly by non-CO2 GHGs.<br> <br> -The primary natural source of CH4 (methane) is microbial decay of organic matter under anoxic conditions in wetlands. <br> <br> ...assuming only that our estimates are approximately correct, we assert that the processes producing the non-CO2 GHGs have been the primary drive for climate change in the past century.<br> <br> The growth rate of forcing by carbon dioxide doubled between the 1950s and the 1970s (Figure 2A), but was FLAT from the late 1970s until the late 1990s DESPITE A 30% INCREASE IN FOSSIL FUEL USE (my caps) . This implies a recent increase of terrestrial and/or oceanic sinks for CO2, which may be temporary.<br> <br> ...oh yeah, and dont forget the natural cycles of solar activity.<br> <br> <br> <br> <br> Also, can you explain why, during the period from 1939 to 1945, more "anthropogenic" pollutants were poured into the oceans and atmosphere than from the usual study periods from 1955-2000, and yet levels of normalcy in temperatures and acidities were found to be the case in as little as 4-8 years after?
