Abrupt Climate System Risks from Hydrogen Sulphide Ocean Outgassing: Part 1 of 2 // Apr 22, 2019

Various ocean coastlines, off Africa, Gulf of Mexico, California, and India have periodic emissions of hydrogen sulphide gas. Concentrations less than 1 ppm smell like rotten eggs, while 500 ppm and higher levels are deadly.

  • Warming, stratifying oceans have more anoxic dead zones (lack oxygen, produce methane, H2S), threats to flora and fauna increases.
  • In the “granddaddy of extinctions” 252 million years ago with over 80% death-rates of many species, a so-called Canfield Ocean was the smoking gun.

 

I discuss present-day incidents/locations of H2S emissions, and discuss future risks.

More Bad Luck for Ottawa in the Climate Casino // Apr 26, 2019

Severe Climate Change Consequences affects places all around the planet, but disproportionately so. Now, it is Ottawa’s turn of bad luck in the Climate Casino (floods-tornadoes-more floods).

  • Yesterday, the mayor declared a flooding emergency;
  • today many soldiers from the army are deploying around the river for sandbagging.
  • The day before, Ottawa City Council declared a climate emergency joining many other cities around the globe.

I chat about ongoing flooding and my coffee bet projection for a peak flow rate of 12,000 cubic meters per second (cms) on May 5th (May 2017 peak was about 9,100 cms).

Ocean Surface Winds and Waves are Growing: Part 1 of 2 // Apr 26, 2019

Often discussed is the fact that over 93% of global warming heat goes into oceans. Not discussed are profound changes ongoing in ocean dynamics, like increased wave heights, wave periods, and wave power.

  • Over the last 3 to 4 decades, winds at the ocean surface have increased by up to 1.5 meters/second (about 8% of 20 m/s).
  • Wave heights have increased by up to 30 cm (about 5% of 6 meters).
  • Increases are largest in southern oceans just north of Antarctica; also at high northern latitudes.
  • Wave Power (Energy per unit time) has increased globally; discussed in scientific paper that I discuss in detail.
