The amount of carbon dioxide in the atmosphere is increasing. That we can be sure of. What gas it is displacing, however, remains a mystery. As atmospheric pressure has not increased, surely the total volume of gas remains constant. Top scientists call this PV=nRT.
Are you feeling tired? If so, that's because there is more CO2 in the air. Only plants benefit from CO2. In fact they need it. This is why all the plants will die. They simply have too much. Imagine Type 2 Diabetes...FOR PLANTS! You might as well say: DIE, BEETS!

No longer the stuff of tin foil hats, erudite logicians from the Bay to the Boroughs and no parts in between have agreed that doomsday is quite inevitable. Indeed, they have even issued a 137th (an 137th?) amendment to its certain date. The most learned among them, honorable Congressbot and known gnashgab of New York's 14th District (The Flailing 14th), known to Park Slope hipsters as "AOC", has pinned the tail on the Doomsday at exactly 2:16 PM Eastern Standard Time, January 21, 2031. YOU HAVE BEEN WARNED (again).

But we knew the sun, old Sol, was a main sequence star. Our fate is tied to its fate, and its fate is to become a black hole. The point is we're going to die anyway, but we had hoped for a few billion years more. Now, with barely a generation remaining, the question is: What kind of booze are we going to sneak onto the plane as we cash out our 401k's for a dream vacation before it's all over. What are your doomsday plans?

We intend to meet Gaia with our boots on. Won't you join us?
