The article Arctic ice melt an ‘economic time bomb’, 26 July 2013 – The Guardian – is one of the telling indicators.
Scientists say rapid melting of summer sea ice in the Arctic may release a “pulse” of methane, with dire implications for the global economy. See the full text:

Says the article:
“ … the release of a single giant “pulse” of methane from thawing Arctic permafrost beneath the East Siberian sea “could come with a US$60 trillion global price tag”, according to the researchers who have for the first time quantified the effects on the global economy. Even the slow emission of a much smaller proportion of the vast quantities of methane locked up in the Arctic permafrost and offshore waters could trigger catastrophic climate change and “steep” economic losses, according to the study published in the journal Nature. The Arctic sea ice, which largely melts and reforms each year, is declining at an unprecedented rate. In 2013, it collapsed to under 3.5 million square kilometres by mid September, just 40 per cent of its usual extent in the 1970s. Because the ice is also losing its thickness, some scientists expect the Arctic to be largely free of summer ice by 2020.”
In my book Toxic Capitalism, published last year, this issue was already mentioned as one of the major threats to our climate. This is just a confirmation.
Another impact mentioned in my book comes out again: see what is happening in places like Switzerland. Still, people, blinded by ignorance, refuse to admit what is going on.

Mountaineers are witness to the changes and fear the consequences when climbing.
