The Anthropocene is nothing more than a fabrication by the global warming worshippers.try reading journals that focus on the Holocene, (or perhaps the Anthropocene)
then come back, and stop acting like a chess playing seagull

Lol. Real climate science & Tony Heller/Steven Goddard? Dude is a standard physics denier. Don’t be a physics denier.
So one of the standard errors people make with sea ice extent is not realizing it is an area measurement. Ice has mass and volume. You weren’t supposing Arctic ice is all the same thickness were you? It tends to be much thinner at the edges and thicker in the center.
If you want to know how much has been lost you have to get the mass or volume.

This paper has a rough estimate of the average of ice from around the planet from 1901-2009 @ 250 +- 30 GT per year. If we conservatively assume it’s continued at that rate then from 1979-2021 it’s taken another 3.5x10^21 joules of energy to simply melt all that ice. That does t include the energy to raise it 0C and then above 0C just the energy to melt it. That’s another 1% to the extra energy already contained in oceans.
What sea ice extent is good for is understanding the albedo of the Arctic. Light colored ice has an albedo of .5-.7 reflecting 50-70% of the light that reaches it. Ocean water on the other hand is 0.06 or 6% reflective. The areas where the sea ice extent have retreated now absorb about 10 times more energy than they did. Which is another reason why NASA finds the Arctic as one of the fastest warming places on Earth.
The Arctic Is Absorbing More Sunlight
Satellites confirm that the Arctic has been absorbing more solar radiation over the past 15 years, a trend that coincides with a decline in sea ice and increase in open water.
Finally currently accepted climate change theory explains why the deepest ocean temperatures haven’t changed much and why the top of the atmosphere is cooler than the lower atmosphere. It’s because greenhouse gasses are more prevalent in the lower atmosphere and prevent a small amount of energy from reaching the upper atmosphere. That increase goes to heating the surface of the planet where circulations of water and air move the energy from warmer to cooler places over time. The bottom of the ocean would be one of the last places to warm appreciably.

???? Really? So you don't think CO2 levels spiking from 280 to >400 (soon almost certainly to >500ppm) >15x faster than it naturally occurs and to levels that have not existed in ~10M years doesn't have any significance?
Brazilian Amazon released more carbon than it absorbed over past 10 years
International team of researchers also found that deforestation rose nearly four-fold in 2019
www.theguardian.com
The Brazilian Amazon released nearly 20% more carbon dioxide into the atmosphere over the past decade than it absorbed, according to a startling report that shows humanity can no longer depend on the world’s largest tropical forest to help absorb manmade carbon pollution.
Antarctic ‘doomsday glacier’ may be melting faster than was thought
An Antarctic glacier larger than the UK is at risk of breaking up after scientists discovered more warm water flowing underneath it than previously thought. The fate of Thwaites – nicknamed the doomsday glacier – and the massive west Antarctic ice sheet it supports are the biggest unknown factors in future global sea level rise.
The worst-case scenarios for Thwaites are grim. It is the widest glacier on the planet, more than 1km deep and holds enough ice to raise the sea level by 65cm.
To heighten scientists’ concerns, west Antarctica has been one of the fastest-warming place on Earth in the past 30 years, and since 2000 it has lost more than 1tn tons of ice.

No, most of your posts contain insults such as the one below. Your over emotional reactions to a scientific discussion exposes your irrationality and shocking immaturity for someone of your claimed age.
Ah, you mean all those big subsidies and assistance given to the coal and oil industries?
Dont be absurd, no-one who is concerned about global warming worships anything to do with it. People are concerned for the planet, and the well-being of their fellow humans. Are you saying that is a bad thing?
You need to grow up, look around, and try visiting the real world.
what on earth are you talking about?
inexpensive, clean renewable energy is being developed and distributed
I for instance manufacture 170% of my clean electricity from virtually zero marginal cost sunlight
which is what BEVs are doing, so your comment is irrelevant and a distraction.

yet there is a refereed scientific journal.
you are being tedious and tendentious at best
The world warms and cools, warms and cools, warms and cools. Global warming zealots like you think it only warms.
The data did not come from Tony Heller! All he did was document the data that is already there. In this case, the data comes from MASIE - Multisensor Analyzed Sea Ice Extent. Here is the link. Yes, they are legitimate.Lol. Real climate science & Tony Heller/Steven Goddard? Dude is a standard physics denier. Don’t be a physics denier.

MASIE-NH Daily Image Viewer
Use the MASIE-NH Daily Image Viewer to see where Arctic sea ice is now and how that data compares to the last four years.
I've always noticed this about you democrat socialists. Whenever somebody, somewhere collects data that does not fall in line with the human-caused global warming mantra, you will do all you can to slander that person. That doesn't fly with folks like me who've worked in the field of meteorology for 40+ years.

No, we understand the potential problems when levels of greenhouse gases suddenly shoot up beyond natural cycles, something you have proven to be incapable of.
Then why is Biden proposing 170 billion to produce BEVs!!!!! If that isn't a market distortion, I don't know what is.
You don't understand greenhouse gasses and/or natural climate variation at all.
The Holocene, or that goofy "Anthropocene" as you call it is actually quite mild compared to the previous interglacial period. Have a look at Greenland ice core data: https://wattsupwiththat.files.wordpress.com/2012/10/49ff5-6a010536b58035970c0134840e51fd970c-pi.png
As you can see, 120,000 to 130,000 years ago the earth was considerably warmer than today. The sea levels were around 20 meters higher as well. Humans weren't belching CO2 out like we are doing today back then either. Human-caused global warming is exaggerated!
You are absolutely going nowhere with this. I already pointed out to you the parameters of both graphs were different. This will give the curves a different appearance (although you can see the spikes). You just keep digging your own hole deeper and deeper. I showed you a way out. Confront Spencer on his blog site if you truly believe he is using a false data set. If Spencer did in fact use false data, he would have been fired by UAH already. He has plenty of enemies in the global warming gravy train industry who are desperately looking for a way to knock out Spencer and Christy. All attempts to derail Spencer and Christy have been colossal failures because scientific scrutiny made their enemies whither away.
