The difference is that this time we're around and its going to affect us.

Global warming is happening at a faster rate than has ever been previously observed (looking at geological record etc). This increase in the warming rate is due to human activity. CO2 is a green house gas, it absorbs the suns energy reflected from the earths surface and holds it in the atmosphere causing an increase in temperature.
We are in the middle of an extinction event right now. It may not be obvious to us in our daily lives but it is predicted that by the end of this century half of all species will have become extinct. The direct effect on people isn't important, or the effect on pandas, elephants, tigers or polar bears. It is the effect on trees and insects that is the biggest threat. If they cannot adapt fast enough as the climate changes then we are all totally screwed.
man being a **** with a gun is the reason Panda's elephants and tigers are diminished, not because its got a bit toastie !!

Skashion said:Such a lazy response from you. I'll just quote an old post:Damocles said:We know more than enough, you're out of date, go and do some research.
EDIT: And a 200ft seas level rise is a prediction of a model based upon Greenland and parts of the Arctic melting. I have no idea where you've goten thousands of years from. I'm not sure you understand the logarithmic effect of warming climate
Skashion said:LOSU is low in some radiative forcings
If the entire East Antarctic ice sheets melted, yes, we'd have 200ft of sea level rises. Calculate how long that would take. Actually, I'll save you some bother. They're not losing mass at the moment so it would take infinite years. Even if you take the most crazy extreme estimates, it would take several thousand years for this to happen.
I don't give a fuck if you're not sure, because I am sure.

mmmmmmmm agenda here !!
Latest IPCC report I'm afraid. Take it up with the IPCC.Damocles said:For a lazy comment. I told you that you're out of date. You counter by showing me a report from 5 years ago.
Skashion said:LOSU is low in some radiative forcings
So? The ones that have a high LoSU all show huge warming. The others we aren't really sure about yet but have a general idea of. I cannot fathom that you do not believe the LoSU to be on the conservative side here for an IPCC paper published 5 years ago nor do I believe that you are not clever enough to use simple additioin to add up the best case screnario of low LoSU forcings against the best case scenario of high LoSU forcings and still see a 5 degree warming. Or why don't you look at the confidence in projected changes? Or the summaries of the entire report?
Your whole opinion here seems to be "we don't know everything therefore we don't know anything". Unless you are playing the conspiracy card, and I certainly hope that you aren't. When AR5 comes out in 18 months, you'll see all those LoSUs shoot up, for the record.

Oh yeah, Greenland takes "infinite" time to melt.

That "infinite time" took four days by the way.

I've no doubt the LoSUs will improve, because science is supposed to go forward, not backwards. If it shows us how best to counteract or mitigate the effects of climate change, that's what I want to see. How can we hope to approach geoengineering without sufficient knowledge to do so?
EASTERN ANTARCTIC Damo, EASTERN ANTARCTIC. I said it very clearly. The evidence currently shows they are gaining mass. Greenland contains water enough only for 6 or 7m of sea level rises, not the 200ft (60m) you were foaming at the mouth about.
Sea ice does not contribute to sea level rises. The East Antarctic ice sheet is the issue because that's on land, and hence does contribute to sea level rises when it melts. The East Antarctic ice sheet, which contains 60+% of the world's fresh water, is gaining mass.Damocles said:Skashion said:Latest IPCC report I'm afraid. Take it up with the IPCC.
These are the only people who issue reports?

You've ignored my point about the difference between the low and high LoSU values still meaning a 5 degree warmig.
Again, we don't know everything. This doesn't mean we don't know anything.

Foaming at the mouth? You sound like Dave. If you want to talk science then let's do that but if you're going to go down this path then I'd rather sit on an ice spike.
You said Eastern Antarctic when I said "Greenland and parts of the Arctic". I meant parts of the Antarctic which you pretty much picked up on and I thought we were still talking about the same thing.
Also "they are gaining mass"? Talk about cherry picking. Yes, East Antartica is gaining mass because its sea ice is rapidly increasing as its land ice is growing. Sea ice is the thing that people are arsed about as like an ice cube in a glass it contributes more to sea level changes. Also, the overall mass of Antartica is shrinking, not growing.

Tht's a fantastic way to yet again show that you don't know what you're talking about. Ice shelfs and ice sheets aren't the same thing. We're talking about Greenland's ice sheet, you're seemingly talking drivel.
either you show it or i will and embarrass you...
before i do explain it please , cos ive got quotes from leading scientist saying that the global warming trend has stopped
waits.................
