NASA Warns Global Warming Models Wrong -Don't Account for Cooling Factors
Top NASA experts say that current climate models predicting global warming are far too gloomy, and have failed to properly account for an important cooling factor which will come into play as CO2 levels rise.
According to Lahouari Bounoua of NASA's Goddard Space Flight Center, and other scientists from NASA and the US National Oceanic and Atmospheric Administration (NOAA), existing models fail to accurately include the effects of rising CO2 levels on green plants. As green plants breathe in CO2 in the process of photosynthesis – they also release oxygen, the only reason that there is any in the air for us to breathe – more carbon dioxide has important effects on them.
Most current climate models don't account for green plants can be expected to grow as they find it easier to harvest carbon from the air around them using energy from the sun: thus introducing a negative feedback into the warming/carbon process, according to Bounoua. Some do, but they fail to accurately simulate the effects – they don't allow for the fact that plants in a high-CO2 atmosphere will "down-regulate" and so use water more efficiently.
