Life as we know it will end by 2025.
Find that improbable?
Consider this then. The Arctic is heating up four times faster than the rest of the planet and this thawing has already begun. The consequences are ominous. The thawing of the Arctic will release enormous quantities of methane.
The Siberian bog has already started giving off small amounts of carbon dioxide (CO2) and methane. Many natural occurrences are self-regulating, but there is no self-regulation in global warming and more specifically, the Arctic warming. This is a run-away event; a kind of global domino effect.
Significant methane release in the Arctic will start impacting the climate within the next 10 years and the complete flip to a methane atmosphere will take an additional 5 years. Since, methane has 20 times the global warming effect as CO2, the release of methane from the Arctic will then trigger a release of methane from the ocean floor as the oceans warm. This second wave of methane release double-insures no plant or animal will survive. Plant and animal species are inter-dependent on each other. Lower level, plant and animal species die off first and this will result in the death of the higher level species.
2025 is neither a pessimistic nor an optimistic prediction but it is the mid-point of my range of years from 2020 to 2030. Predicting the future is difficult because we do not know the exact release rates of methane from the Arctic bogs and tundra.
My estimate of the Arctic temperature rise and release of methane takes into account:
-the burning of trees
-the increase in wind
-heat transfer by the wind
-less snow cover
-increasing CO2 and methane release from the Arctic
The burning of trees
Trees are the kindling which will add to Arctic warming. Today, forest fires have noticeably increased. Another ½ deg. Centigrade of temperature rise of the planet would be disastrous for forests with more pests and fires. The burning of trees is a vicious circle. Trees burn and winds increase which causes more lightning, which starts more forest fires, which are fanned by the increased winds.
