Thanks! Jesus Mary. Thanks to the high specific heat of water. The thermal expansion coefficient of water increases with temperature, so the warmer the water, the more it expands. Luckily, 90% of the ocean is below the thermocline, which is 0-3 degrees Celsius, where the slope is least. Still, it looks like the sea level rise due to warming will only increase with time. We are currently adding 1cm every 3 years. I'm willing to bet that we can get that up to 1cm per year by 2030.This amount of energy would be the equivalent of giving every person on Earth five 1,400-Watt hair dryers, and running them constantly during the 20-year study period, said study team member and oceanographer Gregory Johnson of the National Oceanic and Atmospheric Administration (NOAA).
