I had the ski fields in the wrong place-sorry. It is interesting that deforestation is so important with regard to climate change, and yet not given that much attention, though I believe Australia has been able to reduce its carbon usage calculation by the banning of bush clearing for grazing recently. The moisture explanation makes sense, and does the deforestation explain the situation in the Himalayas too, where the run-off from the snows seems to be declining? Or is that really population expansion?
