Not every melted ice automatically contributes to sea level rise.It is particularly about ice caps on land, such as Antarctica contributing to sea level growth. Think ice cream turns off.
Yes there are already places that are slowly disappearing.There are islands in the Pacific that have already disappeared or are very noticeable disappearing.
We can also look closer to the consequences, there are already islands in both the Wadden Sea and the North Sea and is something where fishing and shipping are still occasionally affected because it is shallow. That process has been going on for much longer.For instance, there has been the St. Elizabeth Flood of 1421, the St. Thomas flood of 1163, the Sint-Juliana flood of 1164. These floods as a result of the increase have in particular ensured that initially land has been flooded in order to be polled often later, but that has not happened everywhere.
From 20 000 BP to 6000 BP increased the sea level 120 meters.The highest position was ~ 6000 years ago and was ~ 2 meters higher than now. Then the sea level dropped, lowest was in ~ 1860. Then the sea level rose to date in an almost straight line and is now 30 cm higher than in 1860. No worrying increase at the moment.
In addition to he answer from Wiebe:
It’s a lot more complicated than it seems.What someone has been trying to explain to me, I will give it as best as possible.
IF you consider the earth to be unformable, there is firstly the question of how much ice is there, and indeed whether it is floating at sea or on land.
Of both, you can calculate what happens.Even a simplified example is quickly complicated. You can calculate that 2/3 of the Earth’s surface is covered with water, and how large that surface is. Then you can calculate how much water is to be included, for example, to leave the water 1 meter higher everywhere. Basically, for 1 meter higher water should be on average in the sea on the dry than average 2 meters (and a little, ice turns off) ice. Or on half of the dry land 4 meters. Or at 1 thousandth of the dry land 2 kilometers. Etc. But then there are effects. There is overflowing land at the edges. What effect does that have? And how much more or less is going to be in the atmosphere (like rain clouds e.g.), how does that strike down and what does that have for effects. And, the area is 1 thing, in some places the sea however is very deep, and is a lot of flow. And probably other patterns in terms of wind (see the other clouds..) This in any case affects the speed of melting.
THEN, the earth is not unformable, she is seen on this scale more like a waterbed than a hard sphere.As the weight of water increases, the earth will deform further. But not everywhere as much. The country “floats” as it were as a crust on glowing rock. Some areas will sink quickly, others will come up right. With on the edges of the tectonic plates (the floating floes land) probably additional seismic and volcanic activity. This can also affect global warming and currents, especially in the atmosphere.
Climate sceptics are eager to intervene to pretend that we do not have to do anything.
But, it is perfectly clear that CO2 is a kind of invisible waste which arises in particular combustion of fossil fuels, and that e.g.Plastics tend to dive into the deepest sea and even into the flesh of the fish that we could eat. Uncontrollably continuing with this kind of activity will certainly have effects, which will change the status quo in ways that may still be bad in detail to predict, but which will certainly have large-scale and unpleasant consequences.
No action advocating is as something as to sit under a staggering boulder because it could also fall just next to us, and not predict it in advance exactly whether the staggering boulder will really fall exactly on our head.
But that it is going to fall when we do nothing, and people are going to touch, there are more than 99% of scientists no longer doubting.
