Larsen C Breaks Off from Antarctica
An iceberg the size of Delaware with enough water to fill Lake Erie twice, about one trillion tons, just launched itself from Antarctica. The ice-shelf was floating and displaced its own weight in water and therefore will not raise global sea levels. However, it was the plug that kept land based ice from sliding into the ocean. When that happens, global sea levels will rise.
Here's the interesting quote from Dan McGrath, a glaciologist at Colorado State University.
“The Antarctic Peninsula has been one of the fastest warming places on the planet throughout the latter half of the 20th century. This warming has driven really profound environmental changes, including the collapse of Larsen A and B,” McGrath said. “But with the rift on Larsen C, we haven’t made a direct connection with the warming climate. Still, there are definitely mechanisms by which this rift could be linked to climate change, most notably through warmer ocean waters eating away at the base of the shelf.”
This is the usual scientist being conservative. Until he can address specific mechanisms linking global warming he can't make that connection. But we certainly can, after all what else could be causing this? The water temperature under the ice shelf has been increasing. Now with the ice gone that changes the albedo of that large area and it will absorb more solar radiation, an example of reinforcing positive feedback.
I have inside knowledge that Russia hacked the iceberg! That must be it.

Fun with math.
A gallon of water weighs 8.34 pounds.
Lake Michigan is estimated to hold 6 quadrillion gallons equaling 50.04 quadrillion pounds or roughly 25 trillion tons.
The new iceberg is roughly twice the size in mass as Lake Erie but is dwarfed by Lake Michigan.
I can see why many people are reporting that the iceberg is equivalent in mass to Lake Michigan. A short time in any search engine will give you many such examples.
I think it's a great lesson to many. Be very leery of what you read and report without doing the research.
Regardless of the path in life I chose, I realize it's always forward, never straight.
The error appears to have propagated from
this business insider article, which now contains a correction.
The earth is a multibillion-year-old sphere.
The Nazis killed millions of Jews.
On 9/11/01 a Boeing 757 (AA77) flew into the Pentagon.
AGCC is happening.
If you cannot accept these facts, I cannot fake an interest in any of your opinions.
There are several.
There were more than a handful of sites reporting this same erroneous information weeks before the insider posted it.
As I said, it's a valuable lesson in how some conduct research or don't even bother.
Regardless of the path in life I chose, I realize it's always forward, never straight.
More fun with math
Lake Michigan has an average depth of 279′
and an area of 22,394 mi²
That computes to a volume of 1.74 10^14 cu ft
Fresh water weighs 62.4lbs per cu ft.
For a total weight of 1.08 10^16 lbs
/2000 = 5.4 trillion tons of water for Lake Michigan
I did the same for Lake Erie = 0.55 trillion tons of water
And Larsen C = 1.288 trillion tons of water
So it's really "only" 1/4 the volume of Lake Michigan hardly enough to "fill" it
However it can fill lake Erie twice over with plenty to spare.
Capitalism has always been the rule of the people by the oligarchs. You only have two choices, eliminate them or restrict their power.
I agree.
My simpleton math is no match for yours.
Least you could do is change your remark about comparison to Lake Michigan.
Thanks.

This is human caused and very bad news.
Hopefully, more and more humans will get po'ed, and go to ecological war against the greedballs over it. I heard the warnings about climate change back in the late 1960s. Rec'd!!

The report I watched on YouTube a couple of days
ago that talked about the upcoming release of Larsen C, did not make the claim that the mass was the same as Lake Michigan. It said the geographical shape (birds eye view) was about the size and shape of Lake Michigan.
Is that part true?
My other question is, where is it going to go? Is it going to float out into the ocean and hit a bunch of ships?
???

The Russians did it to destroy our submarines.
And Trump told them to do it. /snark
I've seen lots of changes. What doesn't change is people. Same old hairless apes.
Everybody thinks they're Perry Mason
and think they are trying a case in court.
"Officer Dinkle, did you take a sample from the alleged ice berg and send it to the lab?"
"Yes, sir, we put it in a little baggie and everything."
"And what did the lab report say?"
"Well, sir, they were unable to find any actual climate change fingerprints, only smudges, so it was inconclusive"
"Your honor, I rest my case. I move that all charges against my Big Carbon client be dismissed, and substantial oil leases be awarded as damages."
Loss of ice volume is what we expect as warming proceeds, and that occurs by means of events like this.

"Reform" meaning what was once public is now private, or heading that direction. Sounds familiar. What do you think will happen to all that light crude now? Welcome back new disco ball overlords!

But if the Mexican people keep that field
They get to keep 100% of the profit.

Renewables take a lot of land area
Speaking of math, here is a video I found the other day. The presenter (a physics professor) argues that the problem with renewables is their land footprint is huge. He not arguing against them, but (like me) he wants to make sure that everyone understands the math. This is especially important for countries that don't have a lot of land area.
I had a similar argument here about a year ago when it was announced that the San Luis Obispo nuclear plant was being decommissioned. The article picture was an overhead shot and one of our locals marveled at all the tidal power at the base. I did the math and explained that to replace that station with tidal power you would have to replace the entire California coast with a big tidal station to generate the same amount of electricity.
There are no easy answers here. Anyone who tells you there are is selling something.

Power trading
I think the solar push in California is great, and having a surplus to sell to other places nearby is not a bad thing (although California's neighbors are apparently leery of economic hegemony in the power sector). But much as the locals might like to think so, California is not a closed system, and we have to look at these problems on a larger scale.

Yes Mexico has peaked. But a billion barrels is
What about 12 days in global oil use to put it in perpective. Oil discoveries are on a forty year down trend. Thermodynamic collapse already gripping us by the short hairs.
As for that glacier. Get some of those big diesel burning ships and push it over here to California we're perennially short of fresh water.
