Donald Trump, Jr.’s net worth has increased six-fold since his father was reelected.
Eric Trump has gotten ten times richer over the same time period.
Funny how that works, huh?

So this is pretty amazing - yesterday EarthCARE sampled Hurricane Humberto straight across the eye! The eye of a tropical cyclone is small so a direct hit is rare: this is the first time EarthCARE has hit one after over a year in orbit! (Showing here also VIIRS on NOAA-20 for context.)

Polar lows - fast-developing Arctic storms - are among Norway’s most hazardous weather systems.
However, satellite data (e.g. from our Metop series) are helping improve forecasts to save lives at sea and on land.

Seen today near Tampa Bay. A Pileus / Cap cloud…like a lenticular cloud on top of mountains except it appears above cumulus clouds.
A horizontal wind aloft hits the cumulus and it is forced upward, it cools and condenses and forms caps. Thanks Xanny Stoll for the picture from Parrish.
