The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Politicians oblivious to the very real threat of nuclear famine

Nuclear Famine, Independent Australia,  17 April 2016   Daryl Williams discusses a recent scientific report in which the devastating global impacts of a small nuclear conflict, including “nuclear famine”, are outlined.

THE COLD WAR is over, the Berlin Wall has fallen, nuclear warhead numbers have declined significantly — so the threat of nuclear catastrophe has passed, right?

Well, sadly no.

In fact, things may be more dangerous today than at the height of the Cold War.

Computer simulations of the indirect climate effects of even a “small” regional nuclear exchange indicate that the whole world would still be imperiled.

A recent 16-page scientific paper, ‘Multidecadal global cooling and unprecedented ozone loss following a ‘regional nuclear conflict‘, by MillsToonLee-Taylor and Robock, outlines the horrific unexpected consequences. Once you boil down the “science-speak” it paints a bleak picture – via an “Earth system model” which includes atmospheric chemistry, ocean dynamics and interactive sea ice and land components – which we should do everything we can to avoid.

It deserves far more attention than it has received and its findings should be informing our foreign, defence and emergency management policies. In summary, the scenario it simulates is as follows:

Firestorms in India and Pakistan from a “small” regional conflict and nuclear exchange would inject 5 Tg (or one million tonnes) of black carbon (smoke, soot, dust) into the stratosphere which spreads globally.

The black carbon heats the stratosphere (by up to an amazing 80 degrees C) and cools the lower atmosphere and surface (by 1.1 degrees C in the first four years, down to 1.6 degrees in the fifth year, slowly rising to 0.25 to 0.5 degrees 20 years later). The colder surface temperatures reduce precipitation by 6% globally for the first five years and still by 4.5% one decade on.

Oh, and hundreds of millions of Indians and Pakistanis would be incinerated to death … but let’s concentrate on the long-term climate repercussions……..

That spells big trouble for Earth in the form of

widespread damage to human health, agriculture, terrestrial and aquatic ecosystems.’

That is,

‘…combined cooling and enhanced UV would put significant pressures on global food supplies and could trigger global nuclear famine.’………

The report also states:

‘The combined effects of elevated UV levels alone on terrestrial agriculture and marine ecosystems could put significant pressures on global food security.’

And yet, I didn’t read anything about this in the 2016 Defence White Paper or in any plans byEmergency Management Australia. Why not?…….https://independentaustralia.net/environment/environment-display/nuclear-famine,8893
