Ya well I wont live to be old enough before it affects me,you either,maybe you should try focus on positive stuff and try and do some good in the world,You seem awful interested in me for some reason.
I must seem to be a threat to your "clique" or something.!

lol!

You and gerry should get a room,he would prolly love that!


More attacks with no contribution.

Ya,let me know when you have something to contribute without attacks,maybe if you and bear get a room you wont be stressed out,go for it ger.

I know you want to.

You allready dirtied this topic like bear has many others.

Nothing to add then dont feel bad if you get insulted.

CBC News In Depth: Saving the Great Lakes: Are we at the tipping point?

...though I'd still like to see if glacial rebound has ever been factored in....

Excellent article...

Since David Lewis has had his cottage in the Fishing Islands on the Bruce Peninsula, he's seen the lake water levels drop drastically.
We see this first hand on Simcoe, although they try and counter it with the use of the Trent Severn.

But then other areas of the Trent, suffer.

While we were fishing for Channel Cats just this past Friday night, we noticed the extremely low water levels. Between the near lack of flow in the sluiceways, to the high number of rocks we had to dodge as we made our way to our favourite spot on the lea side of the hydro dam at Campbellford.

The fishing was off too. We always limit out. We came up 7 short. But at least we managed to bring home some nice fish...

Just trying to keep it clear, which can be a full time task here with some of the more creative posters.



I forget what the point was and I'm too lazy at the moment to go all the way back so I'll just say "yes it is"
That's helpful.



Of course the ice breaks off and melts in the ocean, there's also some evidence of a feedback at the calving face when the cooler meltwater at the surface creates a return current of warmer ocean water lower down which is pulled into the glaciers base and speeds melting.

Outflow glaciers like Jakobshavn the largest on Greenland IIRC have doubled in speed inrecent decades. Jakobshavn puts over 40 billion tons of ice into the Atlantic a year, that's one glacier.
Uh, yeah. That's what I mentioned alright.

Based on what?

The most dramatic wamring on the planet is happening at the poles, when the temperature reaches a certain point the ice will go, there's isn't going to be any process to stop it. There will be relatively thin sea ice formed in the winter months, but that will quickly melt in the summer. The Arctic Ocean is almost certainly going to lose its ice cover.
Based upon observation. If glaciers keep issuing ice into the oceans and it doesn't disappear as soon as it hits the ocean, it's obviously going to start floating around.

The ice from Greenland mostly drifts south(remember the Titanic?) where it quickly melts in the wamer water.
Mostly? That's your argument - mostly?


I seriously doubt that, we've initiated a entirely new cycle of warming that has left the background cycle far behind.
Really? Doesn't look like it here:

http://www.perigeezero.org/treatise/timeline/files/page76_1.gif


Just looking at the evidence from ice core research done by people like Lonnie Thompson and he's seeing evidence of warming that hasn't occured in hundreds of thousands of years. And it's entirely consistent with the principles behind forcing the climate into a wamer state by changing the radiative balance through the massive emission of GHGs. You seem to completely ignore the consequences of that, how do account for all the new energy present due to the scattering of outgoing longwave photons by human generated GHGs?
Yeah. I bet I seem to do a lot of things.

It's a central question, we're greatly outpacing geological activity in emitting some of the very compounds that have played a key role in moderating the global enrgy balance for Eons. That doesn't happen without fundamental changes in the globl environment.
Thanks for pointing out the obvious again, professor.

So is developing the intellectual tools to allow us to change in response to the natural world, why opt out on this one issue?
Who's "opting out"?



If you don't care then why debate it?
To have fun and maybe learn a little. Why do you?

Yes the ice is going to float around, most of it heads south where it melts quicker.

The Artic ice pack isn't mostly accumulated from calved icebergs, it's the result of compacted single year sea ice...hence the multi-year name. And if the warming is significant enough in the Arctic the ocean pack ice will all melt.

I'll get back to you when it actually happens then you can explain where you went wrong.:)

No.... I'm referring to the Hudson Bay Lowlands and Great Lakes Basin rise. Albany River flooding gets worse every year.
I think that isostic rebound is not really a factor in those areas. It happened long ago and I doubt that there is much lingering effect. That is what is happening in some areas of Greenland now as the ice sheet thins at the glacial outflow points.

I know 72 cm per century rises don't mean much in terms of the life of a man, but to the life of a rock and the path of running water, they're but moments. The ice just left 12 thousand years ago. It takes rock a little longer.
