The errors on direct influences to warming have been overwhelming on the "too optimistic" direction. We are above the most pessimistic predictions from decades ago.

The errors on consequences of the warming... I'm not sure one can even talk about them without citing specific studies, because those things tend to have undefined timeframes and way into the future contexts (like this 4°C one... is this even possible to achieve by burning fossil fuels?)
