Challenge the world faces “today”, September 2013

Challenge the world faces “today”, September 2013, is whether climate warming “denialists” and “contrarians”, as well as PR people from the fossil fuel industry will be able to convince everybody else that IPCC was wrong, UN was wrong and that we don’t need to act, to change our way of living. And that is a dead wrong perception.
  I write about it extensively in the last weeks, as I’ve come to realisation that discussing* how much the world is warming up, and if it’s at all caused by humans, is IRRELEVANT. The climate debate aside, human society and production systems have such a great impact on the planet, that we’ve practically begun to terraform-it. As it was written before, human society has “become a geological force to reckon with”, thus, the term ‘anthropocene’ some people are giving the current era (See the Economist (2)).

Gist: we need to change. And change is hard. But necessary. Otherwise, the planet (so not the garden, not the local shop, not your country or the continent you are living on, but the PLANET will not be able to take it. And come ecosystems collapse, mass extinctions and decades of economic, cultural and other stagnation of human society. See below.

"The Cost of Ecological Overspending

Throughout most of history, humanity has used nature’s resources to build cities and roads, to provide food and create products, and to absorb our carbon dioxide at a rate that was well within Earth’s budget. But in the mid-1970s, we crossed a critical threshold: Human consumption began outstripping what the planet could reproduce." (1)
