``... the three researchers write that they «provide experimental support for suggestions and simulation studies predicting that reductions in CO2 alone could have led to loss of tree cover in grassy environments in the last glacial (Bond et al., 2003; Harrison and Prentice, 2003),» and they say that «the large increases in CO2 from industrial emissions over the last century would now favor trees at the expense of grasses,» which conclusion is supported by palaeo - records that indicate that «trees disappeared from current savanna sites in South Africa during the Last Glacial Maximum (Scott, 1999), re-appeared in the Holocene, and have rapidly increased over the last half century,»...
