Our system is so interdependent that a electromagnetic pulse from the sun or nuclear weapon that knocks out the grid also knocks out transportation and the financial system. Oil decline will eventually lead to the end of transportation and fall of civilization as I explain in my book “When Trucks stop running: Energy and the Future of Transportation (Springer 2016). When you add in declining resources (especially phosphorous which is essential for agriculture), corrosion of infrastructure, climate change caused food reduction and rising oceans plus all the other factors in decline and collapse, it wouldn’t take much to turn a gradual into a fast collapse. My gut feeling is that there will be a fast crash that would take years at worst (EMP or nuclear war), and decade(s) at best. Certainly not centuries.

Earth’s Magnetic Flips May Have Triggered Mass Extinctions

http://blogs.discovermagazine.com/d-brief/2014/06/10/earths-magnetic-flips-may-triggered-mass-extinctions/#.U5oyJ41dVXu Earth’s Magnetic Flips May Have Triggered Mass Extinctions At several times in Earth’s history, mass extinctions have come close to wiping life out altogether. The reasons for these catastrophes are still unclear – they’ve been blamed on everything from asteroid impacts to cosmic … Continue reading

Nuclear winter: World-wide ozone loss from small nuclear war. 1 billion + deaths.

Carl Sagan first introduced the idea of a “nuclear winter”, which helped to end the cold war.  The smoke from fires started by bombs would absorb so much sun the earth wold grow cold, dry, and dark, killing plants on … Continue reading

Phytoplankton have declined 40%: they provide food and oxygen for all creatures on Earth

This article from NewScientist discusses how phytoplankton are disappearing — and they provide half of the food animals both in the ocean and on land depend on, plus produce a great deal of the oxygen we breathe. Throw in overfishing, … Continue reading

Why we might not go extinct from fossil fuel emissions

Peak Fossils means Peak Emissions and the lowest to medium IPCC projections at worst This is an overview, other posts in this category contain peer-reviewed papers that show why this is true.  The heart of the problem is that the … Continue reading

Peak Coal is already here or likely by 2020, so IPCC 100 year projections are probably far too high

Peak Coal is happening right now because conventional oil production peaked in 2005 Oil is the master resource without which coal can’ be mined and transported.  As both conventional and unconventional oil decline, the remaining oil will at some point … Continue reading
