West Antarctic Ice Sheet (WAIS) Could Disintegrate Within Decades

Off topic. If you want to complain about China's GHG emissions, start your own thread.
 
Climate Model Predicts West Antarctic Ice Sheet Could Melt Rapidly

and this story is almost three years old. They knew nothing of the enormous cavity now found under Thwaites within the WAIS.[Giant hole in Antarctic's Thwaites Glacier: "Disturbing" discovery as a giant hole was found under Antarctica's Thwaites Glacier - CBS News] WAIS movement rate has recently been characterized as "explosive" Potentially 12 feet of sea level rise by 2100 and rise continuing through the following century at one foot per decade.

There's a good chance your children will see major coastal cities abandoned in their lifetime. But you keep on fighting to keep the coal business alive and your good friends in the oil industry pocketing their billions and billions.

Wrong again Einstein.

The energy policies of governments will always be dictated by costs. Cheaper means governments retain power. Embracing a full- on policy with renewables means cities burn....people in power not gonna let that happen. Duh

What it means is, those with green fantasies are gonna have to suck on it!:113::113::113:

When one can't argue the science.
I just did argue the science, dumbass, because below the ice sheet is a volcano.. God you mother fuckers are stupid...

Oh, so you cant stop China from being the worlds worst polluter, so bitch to US about it, and do nothing.. Typical whiney bitch liberfag.

Is it not fascinating that these people cannot on any level recognize that China makes green dreams a non-starter. Fortunately, most people do recognize this as evidenced by nothing but token activity in terms of climate change action! For 20 years!:coffee:
 
The collapse of the West Antarctic Ice Sheet has been the subject of a great deal of study. This study suggests one thousand years would be a rapid collapse but this is from March of 2009, prior to much research. Modelling West Antarctic ice sheet growth and collapse through the past five million years

Modelling West Antarctic ice sheet growth and collapse through the past five million years

The West Antarctic ice sheet (WAIS), with ice volume equivalent to ∼5 m of sea level1, has long been considered capable of past and future catastrophic collapse2,3,4.

Grounding lines are several hundred metres below sea level and the bed deepens upstream, raising the prospect of runaway retreat3,5.

Reassessment of the Potential Sea-Level Rise from a Collapse of the West Antarctic Ice Sheet

Abstract
Theory has suggested that the West Antarctic Ice Sheet may be inherently unstable. Recent observations lend weight to this hypothesis. We reassess the potential contribution to eustatic and regional sea level from a rapid collapse of the ice sheet and find that previous assessments have substantially overestimated its likely primary contribution. We obtain a value for the global, eustatic sea-level rise contribution of about 3.3 meters, with important regional variations. The maximum increase is concentrated along the Pacific and Atlantic seaboard of the United States, where the value is about 25% greater than the global mean, even for the case of a partial collapse.

Good news: These fellows don't think a WAIS collapse would raise sea level as much as others: only 3.3 m (ten feet).
Bad news, the US Atlantic and Pacific sea boards would see 4.125m (13.5 ft)
 
Are you incapable of debating these points or do you choose to avoid it out of laziness or do you simply not care?

What points, precisely are you debating?

The process to date has been ...

1. You make a disastrous prognostication.

2. We ridicule your doom-saying.

3. You respond by calling names and pronouncing us climate heretics

4. Rinse, repeat.

For the record, that is in no way a debate.

You claim to value science, but you ignore the scientific method.

Present your data without emotion or political bias for examination. Respond to criticism only with additional data. Present the results of repeatable experiments and make no appeals to authority or supremacy of opinion.

No appeals to emotion or disparaging remarks are allowed, they only devalue your argument.

I'm more than willing to have a climate debate ... but, I'm not willing to entertain for a moment we disrupt our economy, give additional powers to government, or create a tax burden on a single person because of a yet to be explained, certainly not demonstrably proved, hypothesis.
 
IF, a big if, the WAIS is headed for collapse then it was set in motion 8000 years ago when we came out of the last ice age not in the last 50 years.
 
Marine Ice Sheet Collapse Potentially Under Way for the Thwaites Glacier Basin, West Antarctica

Antarctic Collapse
The West Antarctic Ice Sheet (WAIS) is particularly vulnerable to ocean warming-induced collapse. The Thwaites Glacier of West Antarctica is one of the largest WAIS regional contributors to sea level rise, and has been considered to be potentially unstable for many years. Joughin et al. (p. 735) used a combination of a numerical model and observations of its recent geometry and movement to investigate the stability of the Thwaites Glacier. The glacier has already entered the early stages of collapse, and rapid and irreversible collapse is likely in the next 200 to 1000 years.

Abstract
Resting atop a deep marine basin, the West Antarctic Ice Sheet has long been considered prone to instability. Using a numerical model, we investigated the sensitivity of Thwaites Glacier to ocean melt and whether its unstable retreat is already under way. Our model reproduces observed losses when forced with ocean melt comparable to estimates. Simulated losses are moderate (<0.25 mm per year at sea level) over the 21st century but generally increase thereafter. Except possibly for the lowest-melt scenario, the simulations indicate that early-stage collapse has begun. Less certain is the time scale, with the onset of rapid (>1 mm per year of sea-level rise) collapse in the different simulations within the range of 200 to 900 years.
 
IF, a big if, the WAIS is headed for collapse then it was set in motion 8000 years ago when we came out of the last ice age not in the last 50 years.

It was set in motion when the grounding line started peeling back within the last decade.

Having attempted to assume you've already won the debate, what was it you wanted to talk about?

Climate changes... that part is indisputable. The degree to which humans contribute to that, the rate of change, the possible consequences of change, all of those are up for debate.
 
Okay.

Here we have a measure of the various forcing factors. What is your opinion regarding these data and what is the bases of your opinion?

So you totally ignore that with volcanic activity and thermal temperatures of water increasing due to such activity, you are still going with your bullshit agenda? I have a great idea, you want to save the planet?
