Climatologists warn of a tipping point when global temperatures trigger catastrophic events and sea levels rise more than 50 feet. what would cause the sea level to rise so greatly? increased precipitation over the continents melting of the greenland ice sheet thermal expansion of the oceans melting of the polar ice cap

Climatologists warn of a tipping point when global temperatures trigger catastrophic events like the melting of the polar ice cap and this will result in sea levels rising more than 50 feet. The correct option among all the options that are given in the question is the last option. That would be the day of doom for most people living on planet earth.

How is the rising of the temperatures connected to the global sea level? Right now, the biggest portion of the world's freshwater is frozen, located in the ice  caps. If the temperature increases, the ice caps will likely melt - and then that water would join the oceans, rising its levels. So the correct answer is: melting of the polar ice cap
