Note: On present climate policy settings, the world is headed to 4 degrees C of warming by 2100, perhaps as early as 2060. We've known that
for at least the last five years, but in the last year its become almost polite to recognise the fact, with the
World Bank chiming in, amongst many others. There is even a conversation about
adapting to 4 degrees.
Last week, Climate Commission scientist Prof. David Karoly told
ABC News: "We are expecting in the
next 50 years for two to three degrees
more warming", and that is on top of the almost 1 degree C that the world has warmed since the industrial revolution.That's up to 4 degrees C of warming by 2060.
In the same week Paul and Anne Erlich asked,
"Can a collapse of global civilization be avoided?", in a new, well-referenced, peer-reviewed paper: "Environmental problems have contributed to numerous collapses of
civilizations in the past. Now, for the first time, a global collapse appears likely. Overpopulation, over-consumption by the rich and poor choices of technologies are major drivers; dramatic cultural change provides the main hope of averting
calamity.
