@Ezekiel903 Месяц назад

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!

@JonnoPlays Месяц назад

AMOC is very important. I just spent a few days watching RU-vid 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 RU-vid. Lots to learn about for those willing to take the time.

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.

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?

@KT-pv3kl Месяц назад

the arctic ice shelves have the same gravitational pull so why do you think it will move north?

@weissfox5857 Месяц назад

@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 Месяц назад

@@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.

For all those thinking that ice melting in a cup of water does not raise the level, there are 2 things: 1. Greenland and Antarctica are landmasses. Any ice being added to water can raise the level. 2. As the video mentioned, plate tectonics plays a role here. As the weight a plate bears decreases, the plate will rise, and some other plate will sink. Though this is not enough to trigger earthquakes, it is enough to rise/lower the sea level significantly. 3. Even in the ideal case where all ice would be present only in the water, and plates would not exist, the melting of ice would still release prehistoric organisms and chemicals trapped in it over many years. So yes, melting of ice is a big concern, as it is currently accelerated by humans. People saying that 'government' is trying to control us are just fear-mongering (though greenwashing is still equally deadly, and ruins the reputation of actual environment conservation efforts).
