One of thickest mountain glaciers melting because of global warming

dublinbay z6 (KS)

Don't like these kinds of stories, but I'm afraid we need to face up to what's happening.

---------------------------------

"One of the world's thickest mountain glaciers is finally succumbing to global warming, a new analysis reports.

The Taku Glacier north of Juneau, Alaska, has started to retreat as temperatures rise, said Mauri Pelto, a glaciologist at Nichols College in Massachusetts.

[. . . ]

This is a big deal for me because I had this one glacier I could hold on to,” Pelto told NASA's Earth Observatory. “But not anymore. This makes the score climate change: 250, and alpine glaciers: 0.”

New photos released by NASA this week show that the melting of Taku has at last become visible.

[. . .]

Taku is one of the thickest known alpine glaciers in the world, measuring 4,860 feet from surface to bed.

[. . .]

A scientific paper in 2016 reported that the ice field is expected to lose more than half its ice by the end of the century and to disappear before 2200, the Daily News said.

Taku's quick retreat was a surprise to Pelto. “We thought the mass balance at Taku was so positive that it was going to be able to advance for the rest of the century,” he said.

[. . .]

“To be able to have the transition take place so fast indicates that climate is overriding the natural cycle of advance and retreat that the glacier would normally be going through,” Pelto told NASA's Earth Observatory. “Taku Glacier is being exposed to melting it hadn’t before, which will drive new changes.”

Laugh it up.

Not even one iota of concern for the generations to follow, huh?

Wow.

You know, I currently live at the bottom of the former lake Agassiz that was formed by receding glaciers during the early part of this warm up.. .Don't think man caused the start of that!

This video is interesting and disturbing. We are losing most of the old ice faster and it isn’t replenished.

The declaration that Greta refers to is linked below. From the scientific journal "Bioscience". Signed by over 11,000 scientists from around the world.

World Scientists' Warning of a Climate Emergency

Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to “tell it like it is.” On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientist signatories from around the world, clearly and unequivocally that planet Earth is facing a climate emergency.

Exactly 40 years ago, scientists from 50 nations met at the First World Climate Conference (in Geneva 1979) and agreed that alarming trends for climate change made it urgently necessary to act. Since then, similar alarms have been made through the 1992 Rio Summit, the 1997 Kyoto Protocol, and the 2015 Paris Agreement, as well as scores of other global assemblies and scientists’ explicit warnings of insufficient progress (Ripple et al. 2017). Yet greenhouse gas (GHG) emissions are still rapidly rising, with increasingly damaging effects on the Earth's climate. An immense increase of scale in endeavors to conserve our biosphere is needed to avoid untold suffering due to the climate crisis...

40 years later it's still pretty much business as usual around the world, humanity proceeding as if nothing is wrong. Americans still driving huge-azz ICE vehicles and eating an average of about 200 pounds of beef a year. Rejoicing that the stock market is reaching record highs as if money is more important than having clean air, water, food, and a healthy biosphere.

I'm thinking that Homo sapiens is just too stupid to get out of its own way.

Trump is due to withdraw from Paris climate change accord. US, the top producing oil and gas country will be the only country outside the accord.


WASHINGTON (Reuters) - The Trump administration said on Monday it filed paperwork to withdraw the United States from the Paris Agreement, the first formal step in a one-year process to exit the global pact to fight climate change

And if 11,000 or eleventy-million scientists aren't convincing enough, perhaps the US Army might be? They released a report in August called "Implications of Climate Change for the U.S. Army" that barely made a ripple. The report is at the link below, available for anyone to read for themselves.

Army War College: The U.S. Military is “Precariously Underprepared” for Climate Change

The United States Army War College recently released a report exploring the significant impact climate change will have on national security and U.S. Army operations, and offering a set of urgent recommendations. The second sentence of the report sets the stage immediately, stating “the Department of Defense is precariously underprepared for the national security implications of climate change-induced global security challenges.”

The report details the most eminent threats climate change poses to national security: severe weather events, mass migration, diminishing global freshwater supplies, changing disease vectors, Arctic competition, stress on the U.S. power grid and nuclear reactors, as well as sea-level rise...

Why do leftists think nature is static? I have news for ya, there was a time on this planet when there was no ice at all!!! Scary.

Who said nature was static? Clearly it's not, cuz when the dinosaurs went extinct, it was subtropical at the poles. And a quarter billion years ago the continents were all jammed together into one big land mass called Pangaea.

And nature is neither left or right. Humans can turn nature or whatever they want into an ideological issue, and deny and rationalize and live in delusion about what's happening to the climate now, but that won't change the laws of Nature. Put billions of tons of greenhouse gases in the atmosphere, and you warm the planet and the climate changes. Simple science and math.

Oh and last I checked, the US military was not considered "leftist".

Civilizations have disappeared in the past because of the climate changing. Even though we know how to curb it we are not paying attention. We will cause our own demise.

Apparently scientists and science are not important to some. Perhaps you prefer to listen to an actor? It is not just glaciers. I agree with Ford. Let the young folks lead on this.

At some point, terrene, there will be people putting ketchup on money to make it more palatable... because they won't find many people who will willingly trade precious foodstuffs for worthless paper... or what were once precious metals, for that matter.

We may not see the really bad stuff within our generation... but our grandchildren will have to suffer for our poor choices and our current complacency where this issue is concerned.

Was that "no ice" time recently? Because it's the speed of change that's the difference between manmade climate change and natural changes that occurred over thousands, millions of years. Serious human impact started with the beginning of the Industrial Age during the 19th century and really took off after WW2 as population growth, transportation, big ag, industry, coal plants started multiplying with amazing speed. As more humans populate the earth, more greenhouse gases are emitted. This isn't hard to understand. The changes we are seeing didn't take hundreds, thousands of years to occur; they've only taken a few decades.

NASA, our military is very much on board in this fight. I didn't know they were "leftists".

The really serious human impact has been in the past few decades. We've emitted more greenhouse gases in the past 30 years than in the entire previous 220 years since the start of the Industrial Revolution. And the rate of emissions is accelerating, not slowing.

This chart from the Union of Concerned Scientists is 5 years old, so today the situation is worse.

Denial... and excuses why we can't move to cleaner energy. That's what we've heard for decades, right here within this forum. And of course, from elsewhere.

Of course, Terrene. It's not likely to get better, either...

Lately the situation has been worsening much faster than previously expected - I don't think there's going to be much of a wait for extreme scenarios to start developing. In fact I've read that they are already happening.

"Don't like these kinds of stories, but I'm afraid we need to face up to what's happening." I already faced up to it and gave up on it a long time ago. The planet is 100% doomed, as people say on reddit "the last thing to do is crank up the AC."

The Outer Banks of the Carolinas looks like it's going to be the first in the US to become uninhabitable. They're already bulldozing homes, taking out paved roads that were destroyed by a 7' wall of water not long ago. Homes that hadn't even been touched by water before suffered major damage. One area is losing FIVE feet of shore each yr. And still they think they can beat back the ocean with sandbags, walls, pumping sand onto beaches. Property taxes are going up, up up to pay for all of this. Futile, nuts.article217026850.html


Our town also is a beach town with a barrier island. While people would pay a fortune for beachfront homes only 15 years ago, now they're extremely difficult to sell...even severely discounted. We love going to open houses and saw several beachfront homes this summer where the stairs to the decks were in the water at high tide...on a nice sunny day. One was built in the 30's, the other in the 70's and they did NOT build them close to the water! Imagine a storm. A shame...that 30's house was my dream home...sigh. Their home insurance is about 5x what ours is slightly inland.
