Sunny day flooding is a coastal phenomenon in which strong tides cause water to gush up from drains and beneath the ground, swamping basements and inundating roads. Rises in sea level due to melting ice-caps are making it an increasingly common occurrence in Florida, where some residential areas are experiencing it on an almost monthly basis. These communities are canaries in the mine, already living with the stark realities of climate change that some still deny is happening. On a planet the surface of which is 70% water, in which the temperature of oceans drives our weather systems, we will all be affected by global warming unless we act now to limit the damage done.
