Are we headed for near-term human extinction?
Recent studies suggest it is irresponsible to rule out the possibility after last week's "warning to humanity" from more than 15,000 climate change scientists

A "warning to humanity" raising the spectre "of potentially catastrophic climate change... from burning fossil fuels, deforestation and agricultural production - particularly from farming ruminants for meat consumption," was published in the journal BioScience last week.
More than 15,000 scientists from 184 countries endorsed the caution, which comes on the 25th anniversary of a letter released by the Union of Concerned Scientists in 1992, advising that "a great change in our stewardship of the earth and the life on it is required, if vast human misery is to be avoided."

The take-away
Out of control climate change means feedback mechanisms may accelerate beyond any capacity of human control. The occurrences discussed in this article are five of some 60 known weather-related phenomenon, which can lead to what climate scientist James Hansen has termed the "Venus Syndrome," where oceans would boil and the surface temperature of earth could reach 462 degrees Celsius. Along the way humans could expect to die in resource wars, starvation due to food systems collapse or lethal heat exposure.
Given all that remains unknown and what is at stake with climate change, is it irresponsible to rule out the possibility of human extinction in the coming decades or sooner?

Comment: Also noteworthy is the fact that at least 69 individual birds have recently been recorded across Wisconsin. Additionally, it's perhaps interesting that the standard interpretation for these influxes doesn't seem to be holding true in recent years - that these invasions occur in 4 year cycles because of successful breeding fueled by periodic high numbers of lemming prey in the Arctic. This cyclic pattern looks to have disappeared this decade, see : SOTT Exclusive: Snowy owls flee northern latitudes for unprecedented fourth consecutive year - Sign of impending Ice Age?
