If we compare the rapid melting of the ice from 12'000 years with today, they should know that half of Northern Europe was under a kilometer-thick layer of ice, and North America too. Today, most of the ice is already on the sea, only in Antarctica is it relatively balanced, but the masses of ice that are now over Greenland are no longer comparable to the kilometer-thick layers that existed in the past. The sea level will not rise much as a result. And the previous model predicted a rise of 2.5°C, we "only" achieved 1.5°C. So they were already 1°C too high! Most civilisations had a flowering period in warmer times, there were safe harvests. No reason to spread panic!

Something that I don't understand: We're told that the planet is warming faster than it ever did before the industrial revolution. But the sea level was 400 feet lower at the peak of the last ice age 20,000 years ago. That's an Average sea level rise of 2 feet each century. When did we record sea level rise equal to that average?

@Mcsteeny 10 сағат бұрын

We haven't seen that level of rise yet. but our current sea level rise is accelerating, and based on the info we have on both the rise in sea level and current gas emissions, we can make projections. though, im no climatologist. Happy to be corrected if im misunderstanding something. Current Rates Global Average Rate: About 3.3 millimeters (0.13 inches) per year since 1993. Recent Acceleration: Increased to about 4.8 millimeters (0.19 inches) per year in recent years. Projections By 2050: Expected rise of 0.3 to 0.6 meters (1 to 2 feet). By 2100: Low Emissions: 0.3 to 0.6 meters (1 to 2 feet). High Emissions: 0.6 to 1.1 meters (2 to 3.6 feet). Extreme Scenario: Up to 2 meters (6.6 feet).

@phillipbatho3213 9 сағат бұрын

@Mcsteeny Remember that 2 feet/century is the AVERAGE from the last 20 millenia. We haven't seen that since humans started recording it, so other centuries must've had considerably more than that. That doesn't really make sense if we have been changing the climate much faster than it ever changed before.

AMOC is very important. I just spent a few days watching KZfaq videos about it. Unfortunately we have absolutely no data as to what would happen if the AMOC did change in some way so there's no way to say it would be catastrophic, but all signs are pointing that direction such as Europe becoming as cold as Canada for example. AMOC is a good subject to explore for sure. Understanding how el niño and el niña are related to sea temperatures is important too. We're finding out more and more how the sun cycle effects our day to day weather so that's another subject of interest worth investigating more here on KZfaq. Lots to learn about for those willing to take the time.

A paper from the University of Toronto several years ago showed that the Antarctic ice shelves have a gravitational pull. That means when they disappear the water currently being pulled to the southern hemisphere will move north. Sea levels will recede in the southern hemisphere and rise in the northern. I've been wondering what effect all this shifting water will have on tectonic plates. Or is the water like the arms of a figure skater, she pulls them in close to spin faster and spreads them out to spin slower? Will the water concentrate at the equator slowing the earth's rotation?

@Pax.Alotin I think the point he was making is that liquid water would start mostly evenly distributing itself and its gravitational pull across all the world's ocean, whereas solid ice can pile up in huge mountains over antarctica, locally increasing gravity in that area relative to the rest of the planet.

@weissfox5857 2 ай бұрын

@@KT-pv3kl There is far less arctic ice than antarctic ice and that gap is widening since the arctic ice is melting faster than the antarctic ice. Ice is more resilient over land than over water, and the arctic has a lot less land than the antarctic. Ice melting doesn't make the gravity of the water molecules go away of course, but mountains exert a locally elevated amount of gravity because the mass is piled up in one place. The same is presumably true for massive sheets of ice relative to the lower and flatter ocean.

It's all about the sun cycles and the earth's magnetic field. The recent solar storm was smaller than previous storms, yet it produced record breaking auroras reaching further around the earth than ever recorded previously. As the magnetic field is disrupted by repeated solar storms it's ability to resist those storms is degraded. We are one big CME away from a serious outage and I'm afraid world governments are not prepared for this disaster scenario. We should be burying electric lines and other cables underground. Makes you wonder why that hasn't happened despite the fact that power lines get blown down over and over by hurricanes and rebuilt just to blow over again.

@ooberholzer 2 ай бұрын

The cost of burying is way higher that build lines. That's why they don't do it... Like for almost everything that is a problem, the answer is "financial benefits" which mostly profits to the ones that could make things right if their own financial interest didn't blind them complitely.

@rps1689 2 ай бұрын

You overestimate these magnetic forces, which are far less than changes in solar irradiation and the Milankovitch cycles (both of which are in cooling phases) and the long-term carbon cycle as reflected in changes in the greenhouse composition of the atmosphere. In addition, those magnetic forces are relatively constant, so while they might impact the fluid dynamics of the atmosphere, it would only be in terms of short-term fluctuations working out to zero over the long-term.

@Tinil0 2 ай бұрын

Where are you getting that the recent solar storm was smaller than previous storms? As far as I am aware it was the single largest since the Carrington event. Being smaller than the biggest ever isn't unimpressive. Our systems held up perfectly, and while that doesn't necissarily mean anything for even larger storms, this storm was bigger than expected, not smaller. It was impressive what we just handled.

In 1990, the IPCC First Assessment Report acknowledged that "Human-made aerosols, from sulphur emitted largely in fossil fuel combustion can modify clouds and this may act to lower temperatures", while "a decrease in emissions of sulphur might be expected to increase global temperatures".Since the 1980s, a decrease in air pollution has led to a partial reversal of the dimming trend, sometimes referred to as global brightening. This global brightening had contributed to the acceleration of global warming, which began in the 1990s. In 2020, COVID-19 lockdowns provided a notable "natural experiment", as there had been a marked decline in sulfate and black carbon emissions caused by the curtailed road traffic and industrial output. That decline did have a detectable warming impact: it was estimated to have increased global temperatures by 0.01-0.02 °C (0.018-0.036 °F) initially and up to 0.03 °C (0.054 °F) by 2023, before disappearing. Regionally, the lockdowns were estimated to increase temperatures by 0.05-0.15 °C (0.090-0.270 °F) in eastern China over January-March, and then by 0.04-0.07 °C (0.072-0.126 °F) over Europe, eastern United States, and South Asia in March-May, with the peak impact of 0.3 °C (0.54 °F) in some regions of the United States and Russia.

Something i've never heard anyone discuss or even mention when it comes to sea level changes is under water volcanism. We know it takes place in many places around the globe and is evident through new islands being created, tectonic plate movement and sea bed eruptions... I'd be very interested to see a detailed video about it's effects, if at all...

@tealkerberus748 23 күн бұрын

Vulcanism is operating at historically low, fairly steady levels now. It is putting energy into the system, just as it's putting carbon dioxide into the atmosphere, but at a steady enough rate that we can discount it as part of what was an equilibrium state until the start of the industrial revolution. Inputs were balanced by outflows. Serious vulcanism is when an area at least as large as a medium sized country is uninhabitable due to repeat lava flows. Think "Deccan Traps" level vulcanism. What we have now is small change compared to that.
