Not this green tea party conservative! I'm all for human population quality and quantity control, now.
There have been a number of articles on when we will cross the Arctic Tundra methane self release and Open ocean self warming tipping points. In 2006 Hansen gave us a decade to reduce emissions 90%, and an article from more studies last year gave us at most until 2023 to do the same. Others have said that with momentum in the system that we may have already crossed the point of no return. Others think that just starting massive 10% per year reductions by 2020 will be OK. Others talk about an even more ridiculous 50% reduction by 2050.
I have noted that many totally leave out the methane turnover scenario. Many know nothing of open ocean self warming from polar ice cap loss, and nothing of oceanic methane hydrates and their sensitivity to explosive release. Some concentrate totally on fossil fuel use and forget that slash and burn agriculture causes 27% of the HGHGs and animal farms/ranches produce 3% in the form of methane 23 times more warming than CO2 for 12 years until it changes to CO2 and water vapor. Clouds have shown to be a slight warming effect from keeping night temperatures higher, while some people insist they must cool the planet.
So many are ignorant that they make up the vast majority. Will they have a change in knowledge, and behavior, in time?
The hope is that we can reduce emissions 90% within a decade, IF we try hard enough in all areas.
But hope runs up against knowledge of human psychology and behavioral inertia. Hope runs up against financial realities.
Can we save our biosphere from AETM and its 6th Great Extinction completion?
Are we too far and fast on the blind road to ecocide? http://www.skepticalscience.com/No-alte ... -down.html
I just can not give up hope and faith, even though it is against logic.
