The BBC ran an article this week quoting Harrison Schmitt in 1972, showing a picture he took, and comparing it to a recent picture. The point was to show how earth had changed due to global warming. The pictures didn’t show any such such thing, and Harrison Schmitt is a high profile climate skeptic.
How 50 years of climate change has changed the face of the ‘Blue Marble’ from space
“the areal extent of sea-ice in the Northern Hemisphere has varied about a constant climatological level but in 1972-1975 sea-ice extent was significantly less. ”
1990 IPCC Report
The changes during the last 50 years were tremendous.
The upper half was changed by global cooling
and the lower by global warming and even the clouds took a completely different shape.
But there are also positive changes : Africa was about to fall from the edge ,
but something or someone (Obama?) pushed it back to the middle.
And maybe I’ll find out one day which photo is the one from 50 years ago.
And thanks god things like resolution,focus,distance,dynamic range,color quality and corretion have not improved during the last 50 years (movies also look the same as 50 years ago) and distance also does not matter,
therefore it is no problem to compare some ancient Hasselblatt snapshot with a modern satellite photo.
Btw – haven’t those 6 baboons that were recently shot into space(and sadly returned ) made some photos too?
Or wasn’t this a real space flight but more the Lear Jet+ Uber version of something Chuck Yeager already did 70 years ago?
Six Baboons not launched into sub-orbital flight atop a phallus-shaped rocket inside a bouncy house with plexiglas windows. Consequently they all went blind from staring at the sun directly at an altitude of 60 miles. Correction – 6000 feet. Helmets were optional even during “liftoff” and “descent”. Because, you know, hair. They did take pictures – selfies. The thing known as Katy Perry was asked to comment on the historic mission: “Historic? I thought it was all about me. Hail Satan!” (This last was edited out). Six Baboons, soon to be a major motion picture. Not to be confused with 12 Monkeys. Oprah! didn’t get to go. She didn’t have the Right Stuff. And she was so looking forward to being weightless
They couldn’t squeeze Oprah through the spaceshipdoor
and then she tried to use the landing capsule as skirt
– that’s why she was not allowed to be no.7.
You can’t have your own gravitational field and L(a)unch into space.
The gravitational pull would bring the earth closer to the moon.
And you don’t want higher tides when you have invested a hundred million in front beach properties and are member of Obamas hawaiian climate change front beach mansion zealots (for some reason
she quietly sold her front beach mansion at the only place named after her – orcas island)
Wow!! The Brits think that climate change has caused Africa to float to the NW, when really it is plate tectonics that did it!
I didn’t bother to read the beeb article but immediately thought:
Apolloimage – Film type and speed, exposure, aperture, filter as opposed to a digital satellite image plus ToD, season and I am sure other imaging differences
Conrad – Hapgood crust displacement? Plate techtonics take a longer time.
