if a telescope could have let us detect global warming 50 years ago
It may not have been a telescope, but it was a scientific observatory, about 50 years ago. When the discovery of rising CO2 levels was made, no one knew exactly what it meant at the time. It's the same with astronomical observatories, the significance of discoveries made today may only become apparent decades later.
For more on the detection of global warming see the thread:
Mauna Loa Observatory - 403.39 ppm CO2
The moon kind of surprises me sometimes. I’ll be out at night and I’ll see a nice moon, and say, “Hey, that looks good.” Then I’ll say, “Oh sh-t, I went up there one time!” Kind of surprises me. It’s like there are two Moons, you know—the one that’s usually around, and then that one. - Michael Collins, Apollo 11 astronaut
