What happens as the continent on the left continues to collide with the
continent on the right?

Can you provide a image that you are talking about? I can tell you what could happen when two contienents collide  

Explanation:

There is a collision

volcanoes varying on side of collison, ocean trenches,  island arcs, mountain ranges, and fault lines can occur because of the collison

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
