I don't think so - I think it is accelerating. This is why we have red-shift effect of far galaxies, and other effects. But I'm not scientist in astrophysics..
What impact does the acceleration have on planet earth?
Global warming on earth and every other planet and a red shift in distant stars light.
I guess it has nothing to do with the ozone layer.
I'll make an attempt to answer: the ideal climate is the climate in which humans and other living things can survive.
what has the greatest impact Too cold or too hot for living things to survive
