Alaskan glaciers melting 100 times faster than previously thought

<i>&quot;Only 50 of approximately 100,000 glaciers in Alaska are tidewater glaciers, and they’re some of the biggest.&quot;</i><p>The takeaways are not that <i>all</i> glaciers are melting faster but that <i>this kind</i> of glacier is melting faster and that similar underwater measurement now needs to be done on other types of glaciers (notably valley glaciers).<p>Most Alaskan glaciers don&#x27;t end in the ocean, which is one significant factor. For Greenland where many do the ocean water is quite a bit colder - &quot;water in LeConte Bay is warm relative to the ice, and even other fjords around the world.&quot;<p>Of course, further studies may end up being done without unemployed University of Alaska researchers[0][1].<p>[0] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20479471" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20479471</a><p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20383708" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20383708</a>

Here is the link to the actual report:<p><a href="https:&#x2F;&#x2F;science.sciencemag.org&#x2F;cgi&#x2F;doi&#x2F;10.1126&#x2F;science.aax3528" rel="nofollow">https:&#x2F;&#x2F;science.sciencemag.org&#x2F;cgi&#x2F;doi&#x2F;10.1126&#x2F;science.aax35...</a><p>People should try reading the actual science instead of some journalist&#x27;s cherry-picked take on the science. It&#x27;s also interesting that Disney (&quot;evil media corporation&quot;) now controls NatGeo.<p>As Bill Gates recently noted, climate alarmists are more of a problem than the &quot;deniers.&quot; Here&#x27;s a story from the BBC this week titled, <i>Climate change: 12 years to save the planet? Make that 18 months</i>:<p><a href="https:&#x2F;&#x2F;www.bbc.com&#x2F;news&#x2F;science-environment-48964736" rel="nofollow">https:&#x2F;&#x2F;www.bbc.com&#x2F;news&#x2F;science-environment-48964736</a><p>This is getting ridiculous. The submitter, in this case, appears to have issues with civility, and is obsessively submitting climate related articles for an account that&#x27;s less than 60 days.

It would be a lie if I said I was surprised, currently I hear news from everywhere that climate change is moving faster forward than expected. The time window we have left to rescue what is left is shrinking. This worries me a lot.

I hope people use this news to motivate changing their behavior. Of course we want governments, corporations, and other institutions to act. History shows that the fastest most effective way is for each of us to start first.<p>Even if disaster is inevitable, there are degrees of disaster and even individual actions can reduce suffering later.<p>The biggest thing I see everyone getting wrong about the environment is that acting on one&#x27;s environmental values is a burden or chore. I used to think so, but found doing so improved my life, despite my expectations before acting.<p>Flying less, cutting out animal food, avoiding packaged food, etc. . . Now that I do them, I wish I had changed earlier.

Title seems a bit click-baity implying some new discovery showing massive underestimation re global warming. The study itself was how fast does glacial ice melt when it&#x27;s under water, nothing particular related to climate change.

Welp. Pack it in boys, it&#x27;s all over.

&quot;They’ve really discovered that the melt that’s happening is fairly dramatically different from some of the assumptions we’ve had&quot;<p>Wait, you mean you actually have to validate assumptions against actual measurement to make accurate conclusions? Who knew?

The Bering Strait has already completely melted and because of this native tribes can no longer cross as they had for generations
