More Ice Breaking

[Prophet Rider]

I guess this is more directed at Frog.

I was reading an article today from theage.com.au, about an ice wall holding the Wilken's Ice Shelf in place, collapsed early April. If I read it correctly, eventually 13,600 square kilometres of ice will now break away and melt into the sea.

No idea how long you have been forecasting but have you seen a rapid increase in air temperature over the last 10-20 years?

If so then I'm assuming in the next 10-20 years there won't be much snow for us Aussies as we are already pushing the threshold of cold enough temperatures to keep snow around for 3 months.

its ok we'll just plonk the giant ice burg on top of our mountains and shave off enough snow each winter, it'll be sweet.

[The Frog]

I remember last July was the coldest on record in the mountains. )

I don't buy into the global warming thing, I'm no scientist.

global warming is just a croc

[DHS]

Have to agree with TC

we were looking out over Wentworth Falls a few weeks ago and I was explaining to the kids that it was once a huge ocean floor.

Climate changed.

Climate Change is a reality. The man induced escalation of climate change is an interesting dinner table dicussion that somehow morfed into globs and globs of tax payers money being diverted away from hospitals and schools into climate change studies, when the reality is that if we're already experiencing it and we've only been changing our atmosphere for a few thousand years, then we're stuffed!!

That said! a smoker can still prolong their life if they quit, even if they've already written their death sentence.

i agree such a croc!

Agree legs, climate change is a reality, the impact of the melting ice caps on the oceans is an interesting one.
To say that we will see global temps rise or fall I would not be willing to say either way. But I think we will see more eratic weather patterns and potentially greater exremes....colder winters..warmer summers.

I mean I may have been in the minority but when I saw "the day after tomorrow" allI could think was "Wow....look at all that snow!"
The climate is changing....sure some ppl say it has changed in teh past...maybe...we dont have records from back then...we can see its changing now and I thnk its a wake up call. We need more focus on preserving this wonderful landscape that provide snow capped peaks for us all to slide down.
Focusing on minimising our impacs on the alpine region whether when we visit or at home I think we would all agree is a good thing.

[spaz]

I don't accept global warming, but do agree with the reaction people and government have implemented.

[triangle]

Hey hey, there's heaps of reasons as to why the climate is changing. It is suspected that we're on the verge of a polarity swap. Magnetosphere is going to get weak for a few thousand years, letting in lots of solar radiation and heat.
Could be sunspot activity, or even pollution. Whatever the cause, I believe it's happening and we need to do something.

In regards to 'the day after tomorrow'. That only happens to the Northern Hemisphere too. I reckon the effects on our mountains would have been less extreme and maybe even desirable.

[Barcoo]

I have on opinion on the issue, however I will say this.
Over the past 100 years the average yearly temps around the globe have risen by half a deg. These are statistics, not opinions.

[Golfpunk]

i hope its a croc :|

[DHS]

I'm pretty sure sunspot activity reduced last year and is expected to be at record low levels this year

[mr magoo]

Is'nt it funny that if you tell people something often enough they start to believe it.It's annoying that especially in the media you only get one side of the issue.Climate has been changing for 1,000's of years and will continue to do so.And contrary to what we're told the planet is actually cooling

Firstly the breaking up of the any sheet will not cause any change to sea levels. Any ice in the water has already increased the water level. Put some ice in a cup, the water level goes up but when it melts there is no change to the water level. The problem is that these sheets act as a wedge stopping terrestrial ice form entering the sea. If this happens then sea levels will rise.

As for climate change, at work climate change is an issue that we constantly deal with. The following are the facts;

Climate has always changed due to a number of factors including; solar activity, changes in the Earth's orbital elements, or man-made factors.

A relationship between atmospheric concentrations of greenhouse gases and global average temperature can be traced back at least 400 million years

Regardless of the cause, the present day conc. of CO2 is approximately 380ppm, which is unprecedented in at least the past 650,000 years

Over the last century CO2 conc. increased by 80ppm which is more rapid that at any time in time in the past 650,000 years.

Also thrown in the mix is inter-decadal oscillations in climate such as the el-nino/la-nina et al., volcanic eruptions and crustal rebound which may artificially influence results/projections. At work we plan for a sea level rise of 0.5-0.9m over the next 100 years.

As for my opinion, I think that any changes to our consumption of non-renewable resources is a good thing. Even if human induced climate change is crap we will still need renewable forms of energy at some stage. Sorry for the long post just wanted to get the facts out there, 2 cents over...

I agree with Legs. If you are interested I suggest you read the book "We are the Weather Makers" by Tim Flannery. If you read the book you will learn that the earth is actually in the middle of a warmer phase which doesn't end for something like another 27000 years (or some such very large number!). If we don't do something to stop global warming I was told there probably would be no snow in OZ in 50 years.

If you believe what Tim Flannery says you believe in Santa Claus

I agree that any reduction in the consumption of non-renewable sources is a vital part of protecting the earth. We've had the ice age, now its a warm age, sure we probably contribute massively, but the earth has been thru it before and will go thru it again.

BUT We use the Earth so we must protect it as best we can.

I have also heard that record new ice formations are happening on the opposite side of the Antarctic which are far greater in volume than what are melting on the Wilken's shelf.
I am doing my bit though, we have more trees at our house than all of our neighbors combined.

[snow king]

Paul - The British just completed a study of Antarctica and whilst they found that the west coast (Wilkin's Ice Shelf) is melting they also found the east cost Ice is spreading at a far greater rate than what is being lost. They also expect Antarctica to increase in size until the ozone hole is repaired. However when the gases can longer escape the atmosphere they expect temperatures to increase in the region and icefields to melt.

Best way to send yourself loopy:

try and understand all the science behind global warming as it is presented by various people/organisations with their agendas that go with them!

[Boardingbuny]

Tell me about it BH, writing an assessment of Flannerys Ideas against crap I cant remember who elses and having to decide who proposed the best way forward was crazy...
