Caught a summary in print. Depressing.

Warming Seas Increase Frequency of Extreme Storms

https://phys.org/news/2019-01-seas-freq ... torms.html


A new NASA study shows that warming of the tropical oceans due to climate change could lead to a substantial increase in the frequency of extreme rain storms by the end of the century.

... They found that extreme storms—those producing at least 0.12 inches (3 millimeters) of rain per hour over a 16-mile (25-kilometer) area—formed when the sea surface temperature was higher than about 82 degrees Fahrenheit (28 degrees Celsius). They also found that, based on the data, 21 percent more storms form for every 1.8 degrees Fahrenheit (1 degree Celsius) that ocean surface

Currently accepted climate models project that with a steady increase of carbon dioxide in the atmosphere (1 percent per year), tropical ocean surface temperatures may rise by as much as 4.8 degrees Fahrenheit (2.7 degrees Celsius) by the end of the century. The study team concludes that if this were to happen, we could expect the frequency of extreme storms to increase by as much as 60 percent by that time.

Warming seas are a gift that will keep on giving thousands of years into the future. Today they hide 90% of the heat accumulation in the system and make it look like BAU will last with enough effort. But the heat chickens are going to come home to roost and the weather states that humanity and its remnants will experience will be something to behold. Winds with incredible speed and sporadic deluge events enough to change the landscape. All framed in a perpetual drought regime where the water evapourates from the ground too fast to sustain plant life and where water in vast amounts prefers to stay as vapour instead of condensing.

And we actually have a real example of a vapour domination regime in the Solar system: Titan. It has a column methane vapour amount of 10 meters (the Earth has 1 meter integrated atmospheric water column). Methane and hydrocarbon rain on Titan literally washes away the landscape and such rain events are separated by centuries. Expect the Earth to move in this direction but never to the full extent.

Humanity has been extremely fortunate over the last 8000 years to have a stable and ideal climate. And this is one of the main problems since there is no experience aside from regional climate change (e.g. US south-west and Mexico about 1000 years ago) which would guide us.

.

I was unaware that water was a sentient being that had a choice about at what temperature and pressure it condensed.
