What Would Happen if All the Antarctic Ice Melted? – My programming school


Yes, there is certainly local weather change. There’s no query that we (the people) have been placing a complete bunch of carbon dioxide into the ambiance and this carbon dioxide is altering the local weather. And issues are wanting fairly unhealthy. Maybe severely unhealthy. So what would occur if the global temperature elevated sufficient to soften the ice cap in Antarctica? How a lot water is there and how a lot would the sea degree rise? What about the Arctic polar cap? Why do not we hear about the issues attributable to the ice that melts at the North Pole? (Because more ice melts each summer.)

Antarctic Ice Cap

Let me begin with the ice at the South Pole. Normally, I’d do a conventional “back of the envelope” estimation and simply get approximate values for stuff. However, in this case, I actually haven’t got a sense for the measurement of the Antarctic ice cap. I’m not positive about the space or the depth of ice. Honestly, it is not my fault. It’s as a result of I grew up with this Mercator projection map. This form of map makes Antarctica impossibly enormous.

To get a tough estimation of the measurement of Antarctica, we consider it as a circle with a diameter equal to the width of USA. See—now we have made a connection between one thing you do not actually have a sense for to one thing you is likely to be acquainted with. So, how far is it throughout the USA? Let’s say it has a width of width of round 3,000 miles (4,800 km). So, if we approximate this as the diameter of a round Antarctica, the floor space could be:

Forgive me, however I’m going to cheat a little bit bit. Since I actually do not know if this worth is legit or loopy, I’m going to take a peak at the Wikipedia Antarctica page

. Oh nice—I’m fairly shut. I really feel higher now. But wait! There’s one different robust factor to estimate—the common depth of the ice sheet at the South Pole. Well heck. I already checked out the web page and I see that the common ice thickness is 1.9 km. It’s all for the greatest. There’s no means I’d have guessed it is that thick. That’s a loopy quantity of ice.

So now, we will visualize this ice sheet as an enormous cylinder—possibly extra like a hockey puck formed cylinder. I can calculate the quantity as the space of the base (a circle) multiplied by the peak. I’m going to maintain the measurements in models of meters simply to make issues simpler going ahead.
