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.

Menhaden going extinct — the key food source at bottom of food web

[ This is a really long introduction so I can reply to a comment that menhaden are “neither overfished nor experiencing overfishing”.   Huh? Both their numbers and range are small compared to their original population. If there were a reduction, … Continue reading

Scientific American: Peak oil and coal may keep catastrophic climate change in check

[ Since conventional oil, 90% of supply, peaked in 2005-6 we’ve been on a plateau.  Since the rate of conventional oil decline exponentially decreasing, and population is still exponentially increasing, it is unlikely unconventional oil like shale “fracked” oil, tar … Continue reading

Escape to Mars to solve our problems? How absurd

Go to Mars?  Really?  We tried already did, and it didn’t work out.  Remember the $250 million 3.14 acre sealed Biosphere 2 complex near Tucson, Arizona back?  It was built to show how colonists could survive on Mars and other … Continue reading

Humans driving species to extinction 1,000 times the natural rate

[ According to a paper published in Science the current rates of extinction are 1000 times the background rate. This estimate is higher than previous estimates is due to a more sophisticated analysis. ] Pimm, S.L., et al, 30 May … Continue reading

Rare Earth Hypothesis: Why intelligent life is rare in the Universe

Wiki has an article about the Rare Earth Hypothesis, which argues that the origin of life and the evolution of biological complexity such as sexually reproducing, multicellular organisms on Earth (and, subsequently, human intelligence) required an improbable combination of astrophysical … Continue reading
