Desertification - Allan Savory TED talk.



Regardless of whether you believe in global warming or not, you should still be afraid of desertification. Whole civilisations and societies have collapsed due to desertification - it's tough and expensive to survive in an area where you cannot grow food and the heat becomes oppressive.

The Gilgamesh talks of a massive Cedar forest in Lebanon and Syria, but it's been gone for 2500 years and the land has turned to desert, because they were chopping it all for export down faster than new trees could grow. Easter Island is another society that destroyed itself by cutting down all it's trees.

In the modern world, China is most at risk. They've a similar population to India, but despite a greater land mass, they are no longer self-sufficient in food production, unlike India. And that's primarily because the deserts are spreading in China, but not in India. And what is not desert is polluted with industrial waste and lost to food production.

It's going to have repercussions. They are intending to lease a lot of land in Ukraine to grow food. I expect they are eyeing the fertile lower Siberian steppes greedily and much of their aggression in the East China sea is about seeking land that is not trashed in the way China is.

So desertification matters.
 
Humans are Earth's biggest threat.

I'm not sure that we're that important really in the whole scale of the universe to be fair. The planet will repair itself when we've finished our time here as we've seen proof of in the past, until eventually this rock becomes a cold desolate uninhabitable place without sufficient solar energy to sustain life.

I do believe that we're completely doomed as a species anyway so we should probably try and preserve our existence for as long as we can though.

When you quote documentaries about science by journalists who don't get it, you could at least watch them. Earth will be devoured by sun a couple billion years down the line.
 
I would like to go back to a time before climate change. And by that, I mean I would like to go back to a time that never existed.


Much arrogance.

So if human activities are accelerating climate change, it doesn't matter because climate change has always existed?

Black and white logic.

I'm pretty sure you can win a forum debate with some low self-esteem individuals
 
Maunders Minimum... Also check out Fallen Angels. Global Warming is the least of our concerns, besides being a brilliant way to fleece the public.

Because if it was such a problem, why would the global warming advocates keep flying around the world talking about it?

Actually Wayne there is a 1 - 2% chance that Mercury's orbit will become so erratic within the next 5 billion years that the entire inner solar system could destabilise to the point that Earth collides with one of the other inner planets. However, it is unknown what the exact fate of our solar system is.

I don't mean this in a bad way old bean, but would you mind just for once fucking off with your relentless typed-out diarrhea.
 
Actually no, that can't happen. Mercury's position, relative to the sun, can be calculated precisely for all eternity, up to 3rd order. You went for two orders of magnitude too large an uncertainty. There's nothing about Mercury's orbit to destabilize because it already is not stable. Google perihelion shift.

Earth can pretty much not just collide with some other planet because you'd need one of them to synchronize orbits with one of the gas Giants which is impossible because of that perihelion shift. Assuming Jupiter and Mercury were on the same orbit, which would pretty much mean a Jupiter year was a long as a Mercury year, Mercury would still get shifted out of that orbit within a couple days.

The gist is, i know more about this than you do, you just don't want to hear it because I'm an asshole about it. Join the Luke ranks. Feel free to bitch.

Saying no offense and following it up with an insult doesn't work btw
