Fifty years of climate heating

    Temperatures are skyrocketing in unprecedented ways all over the world, particularly in polar and near-polar regions. The rise in the far north and far south is three times the global average.
  I grew up on the island of Ask√ły outside the city of Bergen in western Norway near 60.4619° N, 5.0893° E. I also live there, now. Fifty years ago, the winter started in early October and lasted six months, until the end of March, stretching into April. Some years we even had thick ice on the lake by the house in April. We had car races on that and other lakes.
  My mother also made detailed charts of temperatures and weather, so I got into that early.
  Now, we don’t have winter anymore, period. The last real winter with thick snow and prolonged cold we had was in 87/88. Last year we didn’t have a single moment below zero degree Celsius, and we haven’t had that so far this «winter» either.
  There’s no way to explain this away. Once again, the human experience fits the predictions and results of the climate scientists, both here and in the rest of the world.
  The frozen ground in Siberia and Canada is melting. Trees growing in that previously frozen ground is tilting, making yet another startling testimony of what’s happening. Methane stored in that ground is released into the air, aggravating an already grave situation further.
  The ice in Greenland is melting. When all ice there have melted, which will be soon, the ocean will rise with six meters.
  The ice in Antarctica is melting. Humanity will be in even worse trouble when the Thwaites Glacier drops into the ocean. But the real problem here is that the entire WAIS (West Antarctica Ice Sheet) will follow soon after Thwaites. And then the much larger chunk of ice covering East Antarctica will be further exposed to the growing heat. WAIS dropping into the water will make the ocean rise with six meters more. When all ice on the planet has melted, the ocean will rise with between sixty and seventy meters. At least that.
  Eighty-four percent of the world’s human population lives by the coast. We're talking unprecedented migration to the mountains here, if people eventually get their ass moving. If not, they will quite simply drown, of course.
  The ice in the Himalayas is also melting at an unprecedented rate. The impact of that melting is also grossly underestimated. India and China both depend on a steady flow of water from the mountains. When that well runs dry, half of humanity will be without water. Good luck with containing that "unrest".
  The signs are abundantly clear. And we’re talking years, not centuries. Anyone still talking centuries are the errand-boys and girls of Big Oil and the establishment.
  Most politicians and business-leaders talk big about the need for measures fighting what’s happening, but they don’t act on it. On the contrary, they keep subsidizing the oil-industry and give it favorable working-conditions. There is no true will to do anything substantial.
