Global warming and melting of glaciers is one of the pressing problems of mankind today. The gradual melting of the ice in Antarctica, Greenland and Antarctica and the thermal expansion of water can lead to an increase in sea levels. Scientists have calculated that over the past 30 years, 42% of the rise in sea level has been contributed by thermal expansion of water, 21% melting glaciers, 15% melting ice in Greenland, 8% - melting ice in Antarctica. Sea level is constantly rising, but the rate is increasing, especially in the 21st century. Over the past 20,000 years (since the last global glaciation), ocean levels have risen by at least 125 meters.
Small island states, as well as states with long coastlines and densely populated coastal areas, will primarily face the impact of rising sea levels.
A special service based on Google Maps and altitude data allows you to see how the world will change if the level of the oceans rises or falls by a certain number of meters. This can be simulated using the floodmap service. As you can see, the entire east coast of the United States and the densely populated state of Florida are in danger.
Modeling a 50 meter rise in sea level (USA).
It is interesting to imagine events with a very low probability, such as a sea level rise of 50 meters. But, in principle, this can really happen, albeit not in our century (I remind you that the purpose of this article is just to fantasize about "what if …").
But what can be with Alaska, Kamchatka and Chukotka:
Modeling a sea level rise of 50 meters (Alaska and the Russian Far East).
In Russia, most of the West Siberian Plain and the coastal regions of the western and eastern parts of the country may be under water.

Simulation of sea level rise by 50 meters (Russia).
Of course, the rise in ocean level by 50 meters is something from the plot of a fantastic film, but still it is interesting to look at such maps.
