SURPRISE - the Earth is Getting Greener!!
It seems there is always doom and gloom environment news - so here is some good news, as reported by CNN.
NASA satellite imagery reveals that China and India are leading the world in adding volumes of green foliage.
Also, since 2000, the Earth's overall green acreage has grown by 5%, an area equivalent to the Amazon's rainforests.
So.......maybe some positive news.

New Ideas - Where do Winds Come From?
Not only do trees fix carbon and produce oxygen; a new and controversial paper says they collectively unleash forces powerful enough to drive global wind patterns and are a core feature in the circulation of the climate system.
If the theory proves correct, the peer-reviewed international paper co-authored by Australian scientist Douglas Sheil will overturn two centuries of conventional wisdom about what makes wind. And it will undermine key principles of every model on which climate predictions are based.
The paper, Where do winds come from? A new theory on how water vapour condensation influences atmospheric pressure and dynamics, is not designed to challenge the orthodox view on climate science. But Sheil, a professor of forest ecology and conservation at Southern Cross University's School of Environment, Science and Engineering, says he is not surprised that is how the paper has been received internationally.
Boiled down, he says, bad science is protecting shoddy climate models.
The paper, lead authored by Anastasia Makarieva, sparked a long-running and furious debate about whether it should be published at all. At the end of a bruising assessment process the editorial panel of the prestigious journal Atmospheric Chemistry and Physics chose to publish and be damned.
This above is a brief extract from the Weekend Australian article on the subject.
It is controversial, but then so was Copernicus's assertion that the earth rotated about the sun, while Galileo also had a few controversial ideas and theories, since often proved true. Science advances by new ideas being developed and then tested........let's wait and see what occurs as a result of this paper.

Certainly generating a lively debate so far. Data though, is plausible......will be more to come for sure.
