Mount Roraima is the highest of the Pakaraima mountain chain in South America. The 31 square kilometer summit area is defined by 400 meter tall cliffs on all sides and includes the borders of Brazil, Venezuela, and Guyana. The tabletop mountains of the Pakaraima’s are considered some of the oldest geological formations on Earth, dating back to some two billion years ago.

London Smog
In December 1952, a thick smog settled over London for several days. This was a particularly bad episode of the London Fog, which was hardly a natural occurrence...the "fog" was mostly due to the burning of soft coal. It is now thought that the Great Smog resulted in around 12,000 deaths.

This Sort Of Shit Makes Me Nervous.

Authorities in Redondo Beach are investigating what killed millions of fish over the last day at King Harbor Marina.
Fish, including anchovies, sardines and mackerel were floating lifeless in Basins 1 and 2 of the north side of King Harbor Marina.

"There’s basically fish everywhere you go in the harbor," said the harbor's assistant manager, Jason McMullin, who added that there were reports that a red tide may have driven the fish into the harbor in massive numbers where they died because of limited oxygen.
Redondo Beach public works officials were dispatched to the harbor to investigate further but did not have immediate comment.
Redondo Beach officials said initial assessments suggest oxygen depletion in the King Harbor basins caused the massive fish die-off.
City Manager Bill Workman said city officials with the help of marine experts would help determine if there was any environmental issue involved. Tests are now being performed on the water as officials begin removing the dead fish, which city officials estimated to be in the millions.
“There are no visible signs of any toxins that might have caused [the die-off] and our early assessment is that this was oxygen depletion,” Workman said. “This is similar to what we experienced five years ago but that was distinctly a red tide event but there’s no discoloration of the water, no associated foaming in the waves, Workman said. “There are no oil slicks or leaking of substances into the water.”
Workman noted that the harbor had been teeming in recent weeks with bait fish that even after their deaths “had no signs of degradation.”
