Antarctic Ice

[shtferbrains]

So if higher CO2 causes them to melt when will they stop melting?

You would think that if climate change is not occurring or that the rockies are cooling then the 1992 sign would be in ice?

By current measurements, the Athabasca Glacier is retreating up to 16.4 ft (5 m) per year. At its most recent advancement nearly 175 years ago, the glacier covered the entire area where the Icefield Centre parking lot is today, shown in the photo. (Compare the current appearance of the glacier in this photo with the 1844 photo on the informational sign.) According to notes from the CBC documentary “Geologic Journey,” geologists predict that at its current rate of retreat, the glacier will become an alpine meadow in one hundred years. Athabasca Glacier is just one of 2,500 glaciers in British Columbia and Alberta (most are in retreat). Note that there are an estimated 200,000 glaciers across the globe.

Climate scientists know that climate change is occurring more rapidly in some regions of the world than in others. So suggesting that antarctic is representative of global climate change "not happening" is ridiculous.

Since A5 is so certain human caused climate change is not occurring and he has the "evidence" to prove it. You would think if A5 has the evidence, so would all the climate scientists, who spend their careers studying climate, would have the evidence as well?

But when A5 has been asked to name one scientific organization that says human caused climate change is not happening, all we hear is crickets!

No one says climate change isn't happening. Nor that humans are a part of it. Myself included. We have been through this dozens of times.
Enough with the futile strawman argument.

But within your own go to scientific organization, NASA, there is no consensus if Antarctric is gaining or losing mass. With the most definitive recent data from NASA indicating it is gaining mass, not getting warmer, and gaining sea ice. Yet you continue to repeat the lie that it is losing mass, contradicting the best climate scientists at NASA. You know, the ones who spend their careers studying climate, and showing us the evidence.

The reason why this is important is that all of the scary catastrophic scenarios you trot out, are based on Antarctic ice melting. And ALL of the models have it warming and melting at very high levels.
Since it is doing the opposite, and since 90% of the worlds ice is located there, all of the models are clearly wrong.
That means all of the scary future scenarios are even more wrong.
That means sea level rise is overestimated by an order of magnitude.
That means that there science is clearly not settled, nor is there consensus, nor is the debate over.

Perhaps instead of digging yourself ever deeper into a hole, you should call in the boss to take over. dml did come along to attempt some damage control after the disaster you created in the last climate change thread where you got in way over your head.

Or maybe you should leave climate science to the scientists, instead of contradicting them, spreading misinformation and fake news, and making their jobs even more difficult.

Human caused warming relative to natural warming.

[AlbertaFarmer5]

And speaking of distractions to avoid answering the questions.
Since when is the Athabasca glacier a proxy for Antacrtica? Different continent, different hemisphere, different altitude. No one is discussing Canadian glaciers, you brought this up to distract from the fact that you were wrong about Antarctica.
But since you brought it up,

Can you tell us when it started melting?

Can you tell us how big it was back during the much warmer Holocene optimum?

How much did it advance during the little ice age?

What is the correct size for the Athabasca glacier?

And where did you find a photograph from 1844?

Everyone else is seeding and chuck is still looking for articles.

"Or maybe you should leave climate science to the scientists" Huh

A5 you should take your own advice. And maybe rethink the idea that we are going to run out of carbon dioxide if we don't keep burning fossil fuels. LOL

True the Antarctic is the biggest ice sheet by far. But Greenland's ice sheet is also very significant and its melting rate is increasing.

"Ice sheets contain enormous quantities of frozen water. If the Greenland Ice Sheet melted, scientists estimate that sea level would rise about 6 meters (20 feet). If the Antarctic Ice Sheet melted, sea level would rise by about 60 meters (200 feet).

You do realize that with ice loss that once we reach a tipping point ice loss becomes a positive feed back?

You and I will be long gone long before this happens.

Don't get hung up on the evolving scientific understanding of what is happening in the Antarctic. It is very important, but there are many other factors to consider. NASA lays them out in the following link:

Rain delay. Why are you posting if seeding is waiting? LOL

Never said it was a proxy for the antarctic. But you are so sure climate change is not happening in western Canada! In fact you have said its cooling. Why is the Athabasca glacier melting if the climate change and warming is not happening? Explain that please.

That is one long rain delay. It appears to have been uninterrupted since 2006 when you joined.

That could be why you never post about agricultural issues, hasn't quit raining long enough to step outside for decades.

Since you are putting words in my mouth, where did I say climate change isn't happening in western Canada? When did I say it was cooling?

I am currently a net beneficiary of the warming trend we have been in for this cycle.

Based on historical records we are now almost back to being as warm as it was during the 30's in my area.

I am now almost back to growing the types of longer season crops the old timers were growing back then, before decades of cooling made even barley and oats a questionable proposition by the late 70's.

That doesn't change the cyclical nature of climate.

I will be immensly pleased if the cycles don't repeat and we haven't already entered the next multi decade cooling phase. But I'm not holding my breathe, my business and profitability depend on getting this right.

Greenland's Rapid Melt Will Mean More Flooding

The Greenland Ice Sheet is rapidly melting, having lost 3.8 trillion tons of ice between 1992 and 2018, a new study from NASA and the European Space Agency (ESA) finds. The study combined 26 independent satellite datasets to track global warming's effect on Greenland, one of the largest ice sheets on Earth, and the ice sheet melt's impact on rising sea levels. The findings, which forecast an approximate 3 to 5 inches (70 to 130 millimeters) of global sea level rise by 2100, are in alignment with previous worst-case projections if the average rate of Greenland's ice loss continues.

Changes to the Greenland and Antarctic ice sheets are of considerable societal importance, as they directly impact global sea levels, which are a result of climate change. As glaciers and ice sheets melt, they add more water to the ocean. Increasing rates of global warming have accelerated Greenland's ice mass loss from 25 billion tons per year in the 1990s to a current average of 234 billion tons per year. This means that Greenland's ice is melting on average seven times faster today than it was at the beginning of the study period. The Greenland Ice Sheet holds enough water to raise the sea level by 24 feet (7.4 meters).

You post way more than I do there Bud. Are you a real farmer? LOL

[AlbertaFarmer5]

Did you read the thread title?
Do you now think that Greenland is in Antarctica?
Even in the same hemisphere?
Does this information somehow prove that NASA is wrong, and Antarctica isn't GAINING ice mass?
