Increasing Greenhouse Means Increasing Floods, Droughts

August 28, 2017

Among other dynamic activities… As I long predicted, a decade ago, on theoretical grounds, namely the Equipartition of Energy theorem.

Part of Texas was struck by a spectacular hurricane and tropical storm, Harvey, which dumped, and is dumping, an unheard of quantity of rain. That was to be expected, it’s a long foreseen effect of the increasing greenhouse. It is even suspected that, hundreds of millions of years ago, when a greater greenhouse than now ruled, and there was just one major supercontinent, enormous weather systems, of a power unimaginable today, occasionally flooded the otherwise dry interior.

The US President Trump used to complain about CO2, when he was funding and  supporting the so-called “Democrats”, less than ten years ago. To be elected, he engaged in a masquerade denying the shattering potential of a brutal augmentation of the greenhouse. Now he is rising to the occasion, a modern Noah, engineer of his own destiny.

Flood in the Atacama Desert, Northern Chili in 2012. Atacama is the world’s driest desert.

Increasing greenhouse means increasing floods, and not just in the Atacama… Just as it means increasing droughts. The fundamental reason is the increasing temperature: warmer air carries more water molecules. Basically temperature is agitation, and greater agitation keeps more molecules aloft.

Similarly, greater temperatures means greater agitation of water molecules of water in the soil, which then escapes, thus dryer soil, ultimately.

Contradictory effect can emerge, from the same causes. An example: increased floods and droughts, from the same increasing greenhouse.

This has long been well-known in a great desert such as the Sahara.

It’s instructive that a state such as Texas, which produced so much fossil fuels over the last century was struck hard. But so will be the USA, overall: many of the great US cities are threatened by flooding, as sea level will rise.

Somebody just told me: it won’t be tomorrow, that the greenhouse bites. But, in Houston, tomorrow is today, as the city turns into a lake. What people may not understand that much of the greenhouse warming is spent on melting the poles. In particular, the giant frozen expenses of the north. Once all those will be melted, temperatures and storms will shoot up. Why? Because, first, melting ice requires a huge amount of energy. Once the ice is melted, all the heat will go towards other effects. Secondly, the ice creates a strong albedo, the reflectivity of the Earth. Once that’s gone, the soil and water expanses will be capable of much greater warming, as the Sun’s energy will dive deep down inside…
