Yes, she's great! A very lucid thinker and trained as a physicist, so likely to be careful about solutions to complex problems. I am contrasting her claim in the final section of the interview, which I posted above, with for example what was being discussed a bit in another thread a few weeks back: http://members5.boardhost.com/xxxxx/thread/1548939715.html "Co-author Dr Chris Brierley believes there is. He said the fall-out from the terrible population crash and re-wilding of the Americas illustrated the challenge faced by some global warming solutions. "There is a lot of talk around 'negative emissions' approaches and using tree-planting to take CO₂ out of the atmosphere to mitigate climate change," he told BBC News. "And what we see from this study is the scale of what's required, because the Great Dying resulted in an area the size of France being reforested and that gave us only a few ppm. This is useful; it shows us what reforestation can do. But at the same, that kind of reduction is worth perhaps just two years of fossil fuel emissions at the present rate."..." Brierley isn't optimistic about what Shiva is proposing. Myself, I have always assumed that reforestation at best could only take down whatever carbon had been added to the atmosphere by deforestation in a simple reversal of the process, perhaps allowing for a little extra growth in an extremely carbon-rich environment, and that over thousands of years. How is it possible to remove the enormous additional quantities added by the fossil fuels? Shiva seems to be claiming that there is some huge additional capacity for carbon absorption in soil and vegetation. And not just that...but that it can be done in just ten years... There's probably more about this on the internet and I'll have a look when I get a chance. Be interested in what others might find too.
