Why is future sea level rise still so uncertain?

Real Climate

Three new papers in the last couple of weeks have each made separate claims about whether sea level rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty. Two elephant seals in the Southern Oceans arguing about marine ice cliff instability.

Championing Ocean Climate Action at COP28

Ocean Conservancy

The planet has accumulated as much heat in the past 15 years as it did in the previous 45 years; the ocean has absorbed the majority of this excess heat. Scientists have consistently warned that the continued burning of fossil fuels is heating the planet, including the ocean.

The water south of Greenland has been cooling, so what causes that?

Real Climate

Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. For the part entering the ocean as ice, we must also consider that to melt ice requires energy. Greenland ice melt. or other estimates). References. Trenberth, K. & Fasullo, J.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other. While temperatures provide a measure of the Earth’s climate, it is even better to use the global sea level , which provides a far more reliable measure.
