I'm sure the survivors of the Titanic's sinking will be glad to know icebergs in the North Atlantic are melting. May they rest in peace other than that I don't see how it affects my life.
Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change's high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100.
A team of 96 polar scientists from 50 international organisations have produced the most complete picture of Greenland ice loss to date. The Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) Team combined 26 separate surveys to compute changes in the mass of Greenland's ice sheet between 1992 and 2018. Altogether, data from 11 different satellite missions were used, including measurements of the ice sheet's changing volume, flow and gravity.

The findings, published today in Nature today, show that Greenland has lost 3.8 trillion tonnes of ice since 1992—enough to push global sea levels up by 10.6 millimetres. The rate of ice loss has risen from 33 billion tonnes per year in the 1990s to 254 billion tonnes per year in the last decade—a seven-fold increase within three decades.
You should.I wouldn't worry about it
You should.
This is not about "fluctuations." It's about significant acceleration in the amount and rate of glacial ice losses. Since Greenland's ice is on land, when it melts it goes into the ocean, which raises sea levels. In fact, it's now happening so fast that it suggests sea level rise will rise at some of the highest rates currently predicted by climate scientists. And yes, that matters.
why I can't do a damn thing about it.You should.

Human beings are causing the warming. You, as a human being, can do something about it. You can conserve energy, generate less trash, advocate for more sustainable energy sources and green policies, and so on.why I can't do a damn thing about it. That's kind of like worrying about spilled milk.
:roll:that's a fluctuation and I am not worried about that. the sea level has been rising for 20,000 years. I'm not worried about that.
no no I can't, and neither can you. I do not possess the ability to control the minds of 7 billion people.Human beings are causing the warming. You, as a human being, can do something about it.
but I'm not going to do any of those things. Number one I don't think they do any good, number two I don't really want to deal with it. Number three I think "green policies" should not only be discouraged but should be outlawed in some cases.You can conserve energy, generate less trash, advocate for more sustainable energy sources and green policies, and so on.
who said I didn't care about these issues I care very much about stopping the ignorance in hysteria you are spreading. it surprises me how many people are duped by this socialist nonsense being disguised as caring for the planet. I was able to see through it as a child.I.e. This is no different than any other social or political issue. And if you don't care about any such issues, then why are you here?
you can think about it anyway you want, but it absolutely is a fluctuation. over history there has been times when there was less ice on the planet than there is now that means it's a fluctuation.:roll:
Again, it's not a "fluctuation," and this is not normal.
yeah it's been rising for 20,000 years. Before that it was falling and probably before that it roads and before that it sell these are fluctuations and whether or not you think they're normal they seem to be pretty status quo.Sea levels do not magically change independent of the rest of the climate or for no reason at all -- for example, when the climate is warming (due to natural or human causes), the sea level will rise; when it's cooling, it will fall.
to believe something that's absurd is this you must reject all of science. The sea levels have been rising for 20,000 years that's before 1900. they've been racing since the planet has been coming out of an ice age.Sea levels were basically flat before 1900, and are only rising now as a result of humanity's impact on the climate.
I'm not worried because I don't believe there's a problem.Oh, and your mantra of "I'm not worried" does not mean this is not a problem.
no no I can't, and neither can you. I do not possess the ability to control the minds of 7 billion people.

If you want to do those things I'm not going to stand in your way but I'm not concerned about glaciers melting they've been melting for 20000 years.

to think that there is no such thing as an ice age and therefore no such thing as warming up from an ice age is to disregard all of natural Science.
I used to wonder how they can get people to believe something so ridiculous. Now I just pity people who do.
I'm not worried because I don't believe there's a problem.
You and all the other watermelons have done an absolute dismal job of convincing people. And I really think that it has to do with the prophetic religious type predictions you people keep making. The apocalypse has been just five years away for 40 years I was brainwashed with all this crap as a kid back in school remember hearing about how my city would be underwater 10 years ago I don't believe you.
That's why I'm not a watermelon.

I think the best someone can say about the available data is that Human activity "May" be responsibleHuman beings are causing the warming. You, as a human being, can do something about it.

Depending on the level of CO2 sensitivity, which itself is highly uncertain,
the Human contribution could be the majority.
Herein lies the problem, to get back to the climate of say 1960, if the theory and sensitivity are correct,
we would not simply need to reduce emissions, but actually get CO2 levels back to ~320 ppm.
The risks involved in doing that, could be far greater than the risks of adapting to whatever warming may occur.
For CO2 raising, each unit is less sensitive, but as CO2 decreases each unit is more sensitive.
That is correct, the DOD studies in 1960, showed CO2 at 315 ppm was already saturated, with ZEROAnd that's assuming that CO2 is the cause. We could reduce it back to 320 ppm, and not see any significant change.
That is correct, the DOD studies in 1960, showed CO2 at 315 ppm was already saturated, with ZERO
wavelengths between 13.5 um and 16 um, transmitting beyond 10 miles.(16.1 km)
I suspect whatever warming that is still occurring from added CO2, is no longer on that nice log curve,
but far lower.

Do you understand that the 14 to 16 um lines in your cited paper flatten out (read saturation).Oh, for heaven's sake, this whole CO2 absorption saturation issue was put to bed long ago by Gilbert Plass, back in the 1950s. Here's his original paper:
The influence of the 15um carbon-dioxide band on the atmospheric infra-red cooling rate
