Most of the ocean level rise at the moment is due to warmer water being less dense. We are starting to see large land ice masses melt faster and faster - Greenland in particular. The jet stream is now much different than it was when there was more ice.

The Arctic temperatures are rising much faster than elsewhere, and that is also what is driving the weather changes. The amplifying effect of the lower albedo of dark color open water vs light color ice and snow is contributing more and more to melting. The release of methane from the tundra is another strong amplifying affect.

Rising carbon dioxide corresponding to rising temperatures is *not* a coincidence. We also know that the increase in carbon dioxide is coming from us burning fossil fuels because of the isotopes. So *this current* climate warming *is* being caused mostly by humans burning fossil fuels.

We are learning about systemic causation now with changes in storms and droughts and fires and floods and diseases. The ocean level around NYC is about 1 foot higher than 100 years ago, and it will be at least 2 feet higher at the end of this century. When the Greenland ice melts, it will be at least 20 feet higher.

Do you know that thick land ice affects the gravitational pull and lifts the ocean level around it? Did you know that there is so much ice on Antarctica that it is pushing the land under it *down* by almost a HALF MILE? The "extra" gravitational pull of that ice is causing the ocean level south of the equator to be much higher than even at the equator? The is a mountain in Ecuador that is closer to outer space than Everest - but since we measure the height of mountains from the ocean level it is not counted as taller.
