Impact of Nuclear Winter
« on: July 22, 2014, 05:21:01 AM »
Morning all!

Now normally I would not post a link to an article that quote unnamed researchers in Colorado, especially since England's Daily Mail is only a step or two above the National Inquirer, which of course makes it great fun to read but not your most reliable source. Every once in a while they actually write about something of slightly more importance.  In this case about the long term impact of Nuclear Winter.

The original article is entitled Multidecadal global cooling and unprecedented ozone loss following a regional nuclear conflict

The newspaper article posted the following - which I am copying out but have retitled as

The Idiot's Guide to Changes Caused by a Nuclear Winter

Year 0
Five megatons of black carbon released into the atmosphere, which absorbs sunlight and begins to cool the planet. Black carbon rain also kills millions.

Year 1
Average surface temperature drops by 1C (2F).

Year 2
Crop growing season is shortened by 10 to 40 days.

Year 5
Earth is an average of 1.5C (3F) colder than the present day, colder than it has been in 1,000 years. There is also nine per cent less rainfall. The ozone is also up to 25 per cent thinner, increasing UV rays on Earth.

Year 10
Ozone recovers slightly to just 8 per cent less than modern day.

Year 20
Planet warms slightly to 0.5C (1F) lower than the present day.

Year 26
Rainfall increases to about 4.5 per cent less than today.

For me the key to all of this is that the shorter, dryer growing season means that The Rock, upon which I live, goes from providing 5% of its own agricultural food needs, to being able to provide almost none.  Which reinforces the Get-me-off-this-Rock feeling. (Which is too bad because this is a great place to live!)  The point is that it doesn't take very much for that thin agricultural strip to move up a few numbers on the plant hardiness index - which of course would affect the type of seeds you are storing.  So along with all the seeds you have on hand for the current weather patterns, keep in mind that if the world cools significantly and yes, a 1C global temperature drop is significant, then you need to be prepared agriculturally for that as well.

Have a great day all, Lili

Thank you for posting the link along with your ideas and thoughts.

Might want to look more to permaculture, khuglculture and aquaponics for the present as well as the future..
Cheers and take care.

One thing about living in Northern Ontario is that we are already limited to zone 3a /3b which limits what we can grow. However there are some surprising variations in the Province of Ontario due to local factors.

You can check your zone at:

It may never happen. Best to be prepared just in case.
