So.... Greenland was melting faster than now in say, 10,000 BC, right?

klocksib• 6 years ago

yes

samcheng• 6 years ago

Which was the end of the last ice age.

Is that the case, or is it that the method used here can't "see" prior to that ice age to predict things based on formation or rock placement, etc?

Yes. Since then humanity has developed agriculture and become reliant on a stable climate to produce the calories need to sustain our enormous population. Sadly human activity has thrown the systems massively out of equilibrium. Such rapid climate change is going to seriously impact your and my lifestyle.

Good thing for plants on Greenland?

They say if the whole thing melts, it's 24 feet of rising waters worldwide. But they don't project the odds of the whole thing melting, and don't share what they sense will melt at current rates.

Ultimately it's up to us how much ice actually melts. "Humanity has the knob—the carbon knob, and that knob is going to influence the rates of ice loss from the Greenland ice sheet."

Do you have a source for that number?

Check the contributions section here https://en.wikipedia.org/wiki/Sea_level_rise or just cmd+f for "24 ft"

Hey, didn't you know, there is an ice age coming ....

In 1970, The Boston Globe ran the headline, "Scientist predicts a new ice age by 21st century." The Washington Post, for its part, published a Columbia University scientist's claim that the world could be "as little as 50 or 60 years away from a disastrous new ice age."

Just a comment from the late great George Carlin in regards to environmental issues like this;

"Besides, there is nothing wrong with the planet... nothing wrong with the planet. The planet is fine... the people are fucked! Difference! The planet is fine! Compared to the people, THE PLANET IS DOING GREAT: Been here four and a half billion years! Do you ever think about the arithmetic? The planet has been here four and a half billion years, we’ve been here what? 100,000? Maybe 200,000? And we’ve only been engaged in heavy industry for a little over 200 years. 200 years versus four and a half billion and we have the conceit to think that somehow, we’re a threat? That somehow, we’re going to put in jeopardy this beautiful little blue-green ball that’s just a-floatin’ around the sun? The planet has been through a lot worse than us. Been through all kinds of things worse than us: been through earthquakes, volcanoes, plate tectonics, continental drifts, solar flares, sunspots, magnetic storms, the magnetic reversal of the poles, hundreds of thousands of years of bombardment by comets and asteroids and meteors, worldwide floods, tidal waves, worldwide fires, erosion, cosmic rays, recurring ice ages, and we think some plastic bags and aluminum cans are going to make a difference?

The planet isn’t going anywhere... we are! We’re going away! Pack your shit folks! We’re going away and we won’t leave much of a trace either, thank God for that... maybe a little styrofoam... maybe... little styrofoam. The planet will be here, we’ll be long gone; just another failed mutation; just another closed-end biological mistake; an evolutionary cul-de-sac. The planet will shake us off like a bad case of fleas, a surface nuisance. You wanna know how the planet’s doing? Ask those people in Pompeii who are frozen into position from volcanic ash how the planet’s doing. Wanna know if the planet’s all right? Ask those people in Mexico City or Armenia or a hundred other places buried under thousands of tons of earthquake rubble if they feel like a threat to the planet this week. How about those people in Kilauea, Hawaii who build their homes right next to an active volcano and then wonder why they have lava in the living room?"

BTW, you people that keep down voting me because I don't agree with your position, trying to shut me down, stopping me from expressing my opinion, you guys, are fascists.

Don't believe me about climate change scaremongering, here is a long list over the past 50 years of failed environmental disasters....

Please don't source your worldview from a comedian. The snark can be temporarily comforting, but just remember that it's a distraction. Carlin is deeply wrong about the effect we can have on the biosphere. You simply can't simplify the problem without losing all meaningful nuance.

HashingtheCode7• 6 years ago

Fair enough. But did you have a read of the failed climate predictions over the past 50 years? It's hilarious.

Don't believe me about climate change scaremongering

You both missed the point of this bit. If the planet warms 5C and we are all baked to a crisp, we had an effect on the biosphere AND climate change was correct. Carlin's point is that in a astronomical, deep-time sense, it's not the "PLANET" that's in trouble, it's the human race.

There may have been life on Mars, which may have died due to ignorant people like HashingtheCode, but Mars is still there. Mars is fine. The Martians on the other hand...

The Competitive Enterprise Institute is an industry advocacy group, with ties to Koch, coal, tobacco.

https://www.sourcewatch.org/index.php/Competitive_Enterprise...

Their "scientists" have no relevant credentials and are actually "public policy advisors", and usually spread their opinions across multiple unrelated fields (which happens to coincide with whatever disinformation they're trying to spread).

I recently encountered them on Reddit, where people were trying to say the Australian bushfires were just caused by arsonists; these people are from the US and have no idea what's going on in Australia (how did they uncover evidence of arson before the local police?), there was absolutely no evidence for arson, and it didn't explain why it spread so far & rapidly.

Please make sure you get your information from credible sources; as in, sources without a vested interest in industries that have a long history in disinformation campaigns.

rkuykendall-com2• 6 years ago

Carlin: Man-made climate change is real and serious and it's not the planet that's going to die, it's the human race.
Climate change denier: See, like he said, everything is fine!
