2. Do not ignore albedo

Ice reflects light and energy because... It's white!

Sea water is dark and absorbs energy.

So although sea ice melt doesn't directly contribute to sea level rise, warmer seas do. And warmer seas also contribute to accelerated erosion of sea ice shelves which prop up the continental ice shelves, which as they melt directly contribute to sea level rise.

In other words, there are insidious positive feedback systems which makes ignoring these things very, very stupid. And don't let me get started about the frozen methane in the now ever thawing tundra.
