From the Holiday that compels you to honor veterans for protecting our foreign policy interests that only occasionally also served our notion of freedom, it is time to contemplate yet another day of remembrance.

The future Holiday that we’ll celebrate the corporate overlords who protected us from the dangers of not dying in droves thanks to climate change that allowed them to take a ship from Ireland to Alaska: A special “Billionaire’s Day” (because it is not like every day isn’t already Billionaires Day).

Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN’s weather agency said Monday, highlighting the urgency of curbing manmade, climate-altering greenhouse gases.

In April, for the first time, the mean monthly CO2 concentration in the atmosphere topped 400 parts per million (ppm) throughout the northern hemisphere, which pollutes more than the south, the World Meteorological Organization (WMO) said.

It’ll last — at least until they get that whole Elysium ship built.
