What Happens If The Polar Ice Caps Melt

In fact in most parts of the continent it never gets above freezing.

Ironically enough from the point of 1801 1900 the ocean did rise on its own but only by about 2 inches. If the polar ice caps melt this river will be changed significantly and permanently. But since it s floating it will displace a volume of water that would have an equal mass as the ice. Meaning the oceans that the ice caps mostly inhabit.

Even some ice melting will have serious repercussions. Melting land ice like mountain glaciers and the greenland and antarctic ice sheets will change the earth s rotation only if the meltwater flows into the oceans. Without a doubt one of the biggest worries when it comes to the polar ice caps melting is the question of what they ll do to the natural bodies of water in the world. As part of the overall climate change phenomenon the polar ice caps melting is an effect of trapped greenhouse gas emissions.

If emissions continue to rise unchecked the arctic could be ice free in the summer by 2040. We lose arctic sea ice at a rate of almost 13 per decade and over the past 30 years the oldest and thickest ice in the arctic has declined by a stunning 95. Now imagine the ice. If the meltwater remains close to its source by being trapped in a glacier lake for example then there is no net movement of mass away from the glacier or ice sheet and the earth s rotation won t change.

Just from the current. Notably the disappearing polar ice caps will accelerate global warming cause widespread coastal flooding and contribute to rising sea levels. The burning of fossil fuels coal gas and oil causes the earth s temperature to go up significantly. But the average temperature in antarctica is 37 c so the ice there is in no danger of melting.

What is rather unique is that it actually would transform into a sea. The massive influx of new water around the world would conceivably flood the amazon pushing it well past its capacity. Today polar ice caps are melting six times faster than they did in the 1990s. The amazon river would then cover quite a bit of brazil s landscape.

If you have ice floating in the water it displaces some liquid water. If all of the antarctic ice melted sea levels around the world would rise about 61 meters 200 feet.
