IPCC can't see the wood for the trees.

Czech Physicist Lubos Motl reports that since 1945, the European forest density doubled. (Link in title)

Lubos is commenting on a report from the MailOnline (here)
The research, carried out by teams from the University of Helsinki and New York's Rockefeller University, shows that forests are thickening in 45 of 68 countries, which together account for 72 per cent of global forests. Traditionally, environmentalists have focused their concern solely on the dwindling extent of forested areas, but the authors believe evidence of denser forests could be crucial in reducing the world’s carbon footprint
Lubos says that "There are quite many lessons to learn here."
  • First, humans have become capable to significantly engineer the character of their environment because much of the increase of the European forest density was man-made.
  • Second, there is a clear spontaneous component of the growth, too. Nature just likes the improved environment - which includes higher levels of CO2 - and it benefits from it.
  • Third, things such as the forest growth are much more important for the character of our environment than a few degrees of temperature change in one direction or the other. Even if you care about the temperature and you want a lower one (which is unlikely), a forest typically reduces the average temperatures inside by 2 degrees Celsius or so.
 If we managed to increase CO2 from 391 ppm today to something like 1500 ppm (which is unfortunately unlikely), it may be estimated that the biomass growth per unit area would approximately double for all plants - relatively to today.  Read more here....
