The Daily Mail are reporting that co2 is greening the Earth (as claimed in a recent journal article) – www.dailymail.co.uk/sciencetech/article-3557905/Rising-carbon-dioxide-ma… or http://dailym.ai/1qM4Q5h… scientists used satellite data over 33 years to measure leaf cover. Why anyone should be surprised by this is a mystery. Farmers pump co2 into their plastic greenhouses for one reason – to fertilise the crops and obtain higher yields. Scepticss have been saying something like this for the last 30 years – but everyone in the alarmist camp have had their fingers in their ears (and their eyes firmly shut). You just have to scan through the comments – CAGW people still won't accept reality.

Meanwhile, at http://blog.drwile.com?p=14646 … trees exchange nutrients through an underground network of mycorrhiza fungi that grows in woods and anywhere trees congregate. It has also been considered that trees compete with each other – for sunlight, space, water, and nutrients. However, trees also show evidence of co-operation (which came as a surprise).
