Climate Change - Is it too late to avert disaster?

[Azrael]

Please feel free to correct any inaccuracies or ask questions.

I'm in no position to correct any innacuracies , but it sounds plausible enough. In short, due to the position of the earth's orbit, current global warming doesn't fit the pattern set by previous ice ages?

Can't see anything wrong with that as a hypothesis. All I do question is how accurate it is to speak with absolute certainity that we're beyond a point of no return.

I think it's too late. And I think in a few years we'll be back to where we started, no electriciy, mod cons, internet and all traces of civilisation will be gone.

I saw Life After People a while back.
They reckon it'd take about 100 years for most evidence of civilisation to be completely reclaimed by nature.

ETA
Just checked: they reckon massive structures like the Hoover dam could last up to 1000 years

No guns either, as there'll be no bullets, no factories to make them

 

[Dr Jon]

The key thing is whether we'll be able to produce enough food. As the climate changes, the fairly narrow band of conditions which make agriculture viable are going to be squeezed further. And that's before you consider resource depletion, peak (s)oil, peak phosphorous and what have you...

Now, where did I leave my Tardis key...

Global warming is a scandalous hoax. It's 100% natural, and all of the planets are warming. IMO it is a perfectly natural phase that we're going through. Just like the umpteen gazillion other ice ages and wotnot that this earth ahs gone through. a couple of volcanoes will pump out more pollution, than mankind has ever done throughout our entire industrial age. It's a money making scam.

All of science disagrees with you.

 

[sonny61]

The world did get warmer, but jack shit to do with humans. Has not the World's temp not gone up since 97? In fact has it not dropped a bit?

The World's climate has always gone up and down.

You don't have a very good understanding of atmospheric science or climatology, do you?

Any good survivalist will have a formidable stash in an Arizona bunker, raids from ATF agents permitting.

The amount of global sea ice in 1980 and 2009.

1980 Southern Hemisphere = 4.7 million sq km
1980 Northern Hemisphere = 15.0 million sq km
Total = 19.7 million sq km

2009 Southern Hemisphere = 5.8 million sq km
2009 Northern Hemisphere = 14.1 million sq km
Total = 19.9 million sq km

Further proof that spacemonkey was absolutely right.

 

[sonny61]

The latest global averaged satellite temperature data for June 2009 reveals yet another drop in the Earth's temperature. This latest drop in global temperatures means despite Al Gore's dire warnings, the Earth has cooled .74°F since former Vice President Al Gore released "An Inconvenient Truth" in 2006.

Climate change eh? Remember that. I know there's a lot going with bankers and politicians ripping us off and stuff. You'd think the fate of the planet we live on had been sorted, it doesn't get much of a mention anymore. that's the fickle mainstream for you. So how's the species doing with this whole climate change thingy?

I think the seas will boil, the rainforests, burn.

Ah sea ice. I have heard of this......


What months are those figures from, is this sea ice area or sea ice extent. And this very very clearly is not a measure of volume wich is a much more important metric in some ways. Oh and are these averages for a month or figure for a day. And what is your source.....

AND you have said the amount of sea ice in 2009....... we are only half way through. Currently the Arctic basin is expriancing another extreme melt season, its dropping like a stone at the moment, with the very thin ice being flushed out through the Fram Straight at a nerve racking rate. A cool anolomy is settling over Canada, and a significant warm anolomy over Siberia, so fast melt is set to continue. We are looking good to break both 05 and 08 2nd and 3rdf place record and it will be touch and go if we break the 07 record. That without the extreme wether event that caused the 07 melt season.

Remember folks the nothern hemisphere summer is when the earth is furthest from the sun, so we should have the coolest summers for 2000 years and the snow should be much further south reflecting more energy back into space. Instead we have the lowest ice coverage in 800 years at least (other than possible extreme anolomies for a year or so).

I do keep up with this stuff daily.

A drop compared to when?

Why your post is complete bollocks.

The temperature in my sitting room is lower than it was four hours ago. It is also slightly lower than it was this time yesterday. This is not proof that winter has arrived. The fact that the temperature in my sitting room has remained around or above 20 degrees C for most of the last few weeks despite the heating being off is fairly conclusive evidence that it is, in fact, summer.

Now explain how then ten warmest years since 1880 all happened since 1997 if the average global temperature is decreasing.

It's not decreasing: it's increasing, as we come out of the Mini Ice Age.

JC2 does not care about the issue either way. Its just something he can have a whine about to pass the time.

No, I actually have an opinion on it, it's just that it was done to death in those couple of monumental threads, about a year or so ago. I don't have the endurance to recreate that whole thing again, so just a few unsubstantiated comments here and there, like most people do.

 

[Wolveryeti]

I have a hunch that in the most secret of dossiers, large nations have a solution for the global warming problem - essentially seeding the upper stratosphere with reflective particles. This will solve the global warming problem, but with a heavy blood price - as the fertility of crops declines with the reduced sunlight and people starve.

Square kilometers do not measure the amount of the sea ice, they measure the area covered by sea ice. That ice could be just one foot thick, or it could be one hundred feet thick!

Of course, the area covered can be used to estimate the amount of ice floating on the sea. And anyway, the area covered by sea ice is still an important measure for all sorts of purposes, but what it isn't, is a measure of the amount or quantity of the ice.

The amount or quantity of ice would be measured in tonnes, perhaps, or cubic kilometers.

Still early June and the North West passage may be open by the end of this month, although a cold spell may just hold it till August.

The North East passage is very close to opening up as well. And the state of the ice looks very precarious. Of especial not: Just north of Greenland, there are some patches of green low density ice coverage. This is where the bulk of the remain multi year ice is as the cooling bulk of the Greenland ice sheet helps keep temeratures down and the thickness of the ice means less of it is flushed out of the Fram Straight (the gap between Greenland and Svarlsbard island. )


Keep repeating to yourself that there is no problem with this image. It helps with the indocrination.

You don't need factories to make bullets, just some lead, fertilizer/match heads, brass, a couple of molds for the bullets and shell casings, and a heat source hot enough to melt lead & brass.

And while you're sorting all that shit out I've shot you in the balls with my crossbow already

 

[kyser_soze]

Yeah, of course you have.

You've already tripped a wire on a DIY claymore and couldn't get close enough to fire your crossbow at me.

 

[Barking_Mad]

The problem i have with climate sceptics is that I don't hear them saying that looking after the planet in a better fashion is a good thing to do, regardless of the fact they believe the science is wrong. It's almost as if they WANT to carry on polluting and destroying....

wire will be inshort supply after it has to be beaten out by hand with ahmmers. As will be the refined chemicals needed for your claymore and bullets. The good old spear will still have the last laugh.
