So my question could dinosaurs survive a world heated by global warming? I ask because they lived in a time where the earths temperature was much hotter.
Temperature was much hotter but the vegetation was very different.
Grasses didn't start appearing until after the dinosaurs were gone, so there were no grasslands, savannahs or prairie habitats. So that's one big difference.
The continents were in completely different latitudes, arrangements and relationships to each other which is another big difference. Where dinosaurs were then are not in the same places on the globe now.

Their world is literally gone forever.
Making the place hot enough for them would not be enough for them. They need food for starters.
I understand oxygen levels where higher back when the likes of T-Rex walked the earth, so I’m not sure such a dinosaur could survive with the oxygen levels of today. Maybe someone in the know can answer that. Would a cloned T-Rex keep fainting or just suffocate to death?
It's the other way around apparently, though the older view that oxygen levels were higher still gets a bit of a run.

Poaceae - Wikipedia, the free encyclopediaUntil recently, fossil findings indicated that grasses evolved around 55 million years ago. Recent findings of grass-like phytoliths in Cretaceous dinosaur coprolites have pushed this date back to 65 million years ago.[1][7] Indeed, revised dating of the origins of the rice tribe Oryzeae suggest a date as early as 107 to 129 Mya
Interesting article regarding bird oxygen tolerance to that of a dinosaurs. I would have imagined displacing a T-Rex out of sync with its natural environment by 100,000 million years would have serious health complications after prolonged exposure to much higher (Or lower) levels of oxygen than the dino lungs were adapted to. However, I’m thinking it’s not just their lungs that have to be environmentally adaptable. What about the dino brain? Could it cope with what the lungs breath in?
