Antarctica Melting 3x Faster Than We Thought

Are we back to 'it's melting again'?

it seems like every other year or so the major scientific information changes from its net gaining ice to its net losing ice.
This is measuring average annual loss since 2012, which is triple the historical average from 1992 through 2011. It's not a matter of changing our minds from one year to the next, although that is frequently used as propaganda, whose effectiveness you are now a personal witness to.
 
I wish earth had the opposite problem or something. water decreasing and more land.

we need more land at this rate plus many cool beach areas will go under water.
Global warming will free up more land than is lost in the coastal areas from the reports I have seen.

tons of arable land in northern Canada and Russia and China will be freed from ice and snow.

Some of this planets most lush times with the most land arable land was when the planet was much warmer.

then what is this all about australia used to connect by land bridges to all of south east asia? It seems opposite. Yeah you get some freed up snow and ice land but that is already on land. You then lose the arctic and antartica and many other areas.
 
I checked the air in my tires last week. Some ive done my part
 
but Candace Owens said she doesnt believe it.... and she seems like a trustworthy individual

"While the Antarctic sea ice yearly wintertime maximum extent hit record highs from 2012 to 2014 before returning to average levels in 2015, both the Arctic wintertime maximum and its summer minimum extent have been in a sharp decline for the past decades. Studies show that globally, the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice."
 
Who gives a shit. Daddy got the space force finding a new frontier for us to enslave and take over. Hopefully without garbage liberal threads from losers.

And that's just area, which fluctuates.

Just remember during the last election not one right wing candidate said they believe in climate change. Not one.

And the people who said “it miggghhhtttt be something” also said “there is nothing we can do about it.”

In fact the gop is speeding up the process for short term profits. Most frightening polictal party on planet earth. A danger for the entire planet
 
Ridiculous regulations that come out of government studies doesn't help the cause. A lot of it is image and not helpful in any real sense but people will follow and swallow if it's taged with saving the planet.
Tier 4 engines are a nightmare, burn more fuel, require scrubbers, super expensive, difficult to work on and take up more space.
They hardly reduce emissions per gallon but it's a feel good thing so that's all that counts. I mean we have to do something right?

Yes. We were referring to REPORTS on antarctic ice and how those reports change.

Sea ice extent measures area, not volume/mass. Due to refreezing, changing currents due to melt, and other effects specific to Antarctica, the ice can grow in surface area while losing mass. To see the idea, place an ice cube on the ground before the temperature drops below freezing.

You are not working with the relevant concepts and definitions. And I'm not even formally educated in this area. This is painful, it pains me.

I am not trying to work with anything. We are addressing the reporting. If you want to adress the usage of the underlying data that is a different thing.
 
There's no magic bullet out there.

Hype Meets Reality as Electric Car
Dreams Run Into Metal Crunch

By Elisabeth Behrmann, Jack Farchy and Sam Dodge
January 11, 2018
When BMW AG revealed it was designing electric versions of its X3 SUV and Mini, the going rate for 21 kilograms of cobalt—the amount of the metal needed to power typical car batteries—was under $600.

Only 16 months later, the price tag is approaching $1,700 and climbing by the day.

For carmakers vying to fill their fleets with electric vehicles, the spike has been a rude awakening as to how much their success is riding on the scarce silvery-blue mineral found predominantly in one of the world’s most corrupt and underdeveloped countries.

“It’s gotten more hectic over the past year,” said Markus Duesmann, BMW’s head of procurement, who’s responsible for securing raw materials used in lithium-ion batteries, such as cobalt, manganese and nickel. “We need to keep a close eye, especially on lithium and cobalt, because of the danger of supply scarcity.”

Like its competitors, BMW is angling for the lead in the biggest revolution in automobile transport since the invention of the internal combustion engine, with plans for 12 battery-powered models by 2025. What executives such as Duesmann hadn’t envisioned even two years ago, though, was that they’d suddenly need to become experts in metals prospecting.

Automakers are finding themselves in unfamiliar—and uncomfortable—terrain, where miners such as Glencore Plc and China Molybdenum Co. for the first time have all the bargaining power to dictate supplies.

“They’re a lot bigger—but the reality is guys like us are holding all the cards,” said Trent Mell, chief executive officer of First Cobalt Corp., which is mining the mineral in northern Ontario and setting up talks with automakers seeking long-term supplies.

A creuseur, or digger, descends into a copper and cobalt mine in Kawama, Democratic Republic of Congo.
Complicating the process is the fact that the cobalt trail inevitably leads to the Democratic Republic of the Congo, where corruption is entrenched in everyday business practices. The U.S. last month slapped sanctions on Glencore’s long-time partner in Congo, Israeli billionaire Dan Gertler, saying he used his close ties to Congolese President Joseph Kabila to secure mining deals.

There’s also another ethical obstacle to negotiate. The African nation produces more than 60 percent of the world’s cobalt, a fifth of which is drawn out by artisanal miners who work with their hands — some of whom are children. The country is also planning to double its tax on the metal.

Automakers may not have the luxury of choice as countries across the world ban gas and diesel engines to slash carbon emissions.

If each of the billion cars on the road were replaced today with a Tesla Model X, 14 million tonnes of cobalt would be needed—twice global reserves. Even a more realistic scenario for people to drive 30 million electric cars by 2030 requires output to be more than trebled, according to a study commissioned by Glencore from commodity analysts CRU Group.

The projections have made the lustrous metal, a byproduct of copper and nickel mining, into one of the most coveted commodities. Its price surged 128 percent in the past 12 months, in part because hedge funds including Swiss-based Pala Investments stockpiled thousands of tonnes of the stuff, which is used to power everything from mobile phones to home electronics.

“There just isn’t enough cobalt to go around,” said George Heppel, a consultant at CRU. “The auto companies that’ll be the most successful in maintaining long-term stability in terms of raw materials will be the ones that purchase the cobalt and then supply that to their battery manufacturer.”

To adjust to the new reality, some carmakers are recruiting geologists to learn more about the minerals that may someday be as important to transport as oil is now. Tesla Inc. just hired an engineer who supervised a nickel-cobalt refinery in New Caledonia for Vale SA to help with procurement.

But after decades of dictating terms with suppliers of traditional engine parts, the industry is proving ill-prepared to confront what billionaire mining investor Robert Friedland dubbed “the revenge of the miner.”

Take Volkswagen AG. The world’s biggest automaker has one of the industry’s most ambitious targets for battery car sales. Cobalt producers spurned its attempt in September to get long-term cobalt supplies at prices fixed well below market rates. Two months later, Volkswagen wooed them to meetings at its 30,000-seat stadium in the German city of Wolfsburg, hosting each in a separate hospitality box.

The carmaker has eased its price demands and may succeed in securing cobalt supplies this year, according to people familiar with the talks.
 
The earth has been much hotter than the present in the past, and will continue to heat up after we reduce green house gasses. This is not a political problem. It is an inevitable problem that should be addressed logically.
The argument is that the natural cycle has been super charged by human activity. The temperature is rising at a rate that should raise some alarm bells.

Also, logically, many of the same steps people want to reduce climate change also directly affect other environmental areas of concern, most notably clean air, water, and ground stemming from less reliance on fossil fuels and more oversight into what is being dumped in our waters and skies. Oh, whoops, the EPA head is Scott Pruitt.
 
Would you have preferred another ice age in 1,000 years, putting Canada and Europe under a mile of ice in a 5,000 year never-ending winter? I don't think that would work. Shore line property is a long term sucker bet, and we basically had to terraform to prevent the destruction of the places where everybody in the world wants to live.

in a 1,000 years? sure. lol
