Answer:

C) New research points to a powerful link between climate change and armed conflict. It also finds that countries that are ethnically mixed are more likely to experience this kind of conflict. But their results may actually tell us more about the consequences of colonialism than ethnic diversity.

A) This new research joins a raft of existing research on climate change and conflict – often reaching competing conclusions. What is the link between climate change and conflict? This isn’t an issue that can be solved with one study. There are in fact hundreds of studies looking at this issue. And they don’t all reach the same conclusion.

D) Some studies do show that climate impacts lead to increased violence. But some studies find that there was actually no connection at all. Being hit by a disaster or climate change impacts didn’t make any difference to levels of violence. Some studies even found the opposite. Climate change impacts actually reduced some kinds of violence.

B) So what happens when we look at all this research as a whole? Yes, some of the studies point in different directions. But what about when we consider all the research together? Does it point to powerful climate – conflict connection, or not?
