This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Just FYI, sea levels are going to rise primarily because much of the melting ice is not floating in the water, but land based. Thermal expansion is definitely part of it, but secondary.
Nah, the amount of snow and ice on land like in Antarctica is extremely small to the amount of water in the sea, especially since it needs to expand outward and cover even more land.
With thermal expansion even only being a clouple of % is enough to rise everywhere multiple meters. Which is nothing compared to the +10km of dept at the Mariana Trench.
Of course, all of it adds together in the end. It will be bad for everyone no matter where it comes from.

Might change when all of the ice melts, but to this point it contributes twice as much per year, per NASA. If you have some other source I would be interested in reading it.
