You've left out a few minor details. Which areas will be green and which areas will be brown ? How will rainfall distribution be affected ? Will sea level rise or fall ? Will deserts become bigger or smaller ? Will there be new deserts and where will they be ? What is going to replace the glacial melt water that millions of people rely on ? Will the increased temperature cause more extreme weather ? Will the increased atmosphere moisture cause more flooding ? Etc, etc, etc.
Care to post all the data that supports your conclusion ?
Btw. Here's a quote from your link.
" The paper, published today in Nature Climate Change, shows that up to half of the Earth’s vegetation-covered land is now “greener” than it was 30 years ago. Most of the change is down to rising CO2 from human activity, say the researchers.But this shouldn’t automatically be taken as good news. Any benefits of “CO2 fertilisation” may be temporary and are outweighed by the negative consequences of climate change, such as extreme weather, sea level rise and ocean acidification. "
