A team of researchers in the U.S. claims that climate models used to predict the rise in CO2 concentrations in the atmosphere are approximately 17 percent too high because they incorrectly approximate how much CO2 plants ...
The level of carbon dioxide in the atmosphere increased at a record pace last year, US government scientists reported, raising new concern about one of the top greenhouse gases and the effects of global warming.
