Did warmer seas lead to methane release?

Under the ocean floor, there are huge deposits of methane hydrate. The compound is unstable and can release the climate killer methane under certain conditions – such as higher water temperatures. Using a new type of “thermometer”, researchers at Goethe University Frankfurt can measure what the temperature on the sea floor was millions of years ago based on a type of carbonate formed by microorganisms where methane was present. This work might make it possible to answer the question of whether a warming of the oceans in the past led to an increased release of methane.
