What are the precise damages of climate change? Some examples of major issues affecting humanity are given, such as malaria transmission. We know that global warming has spread malaria transmission, but by how much and how fast? What will be the effects on major crops of global warming? There are also uncertainties about the performance of technologies impacting climate change (both negatively and positively), from batteries to carbon capture and sequestration.

He stresses that their is enough precaution to urge us to be careful about climate change.
