In 2007, I read three books about climate change. The best one was "The Weather Makers" by Tim Flannery. The most important factors are:
The white ice covering the poles reflects the warm rays from the sun. When white ice melts, the dark water absorbs the suns rays. Cold water absorbs carbon dioxide. Warm water does not. Once the oceans are saturated with carbon dioxide, they can release stored methane, climate-warming gas. As for sea levels, it is not just affected by polar ice melting. Warm water has more volume. Maybe Christo can wrap the poles in white (no joke).
