THE MESSENGER OF DOOM IS AT IT AGAIN ! ! 😾
It doesn’t necessarily mean that earth will get colder. The sun’s luminosity is also going to increase, and so earth’s temperature. Eventually this will cause life to get extinct.
If earth doesn’t get engulfed by the red giant sun, then yeah, earth will be cold, near absolute zero
How much time before that happens? billions of years. Not issue for today’s individuals
