but so far nobody can find anything else that explains the evidence better.
So correlation is causation.
Edit. Natural variation - couldn't explain the warming but can explain the hiatus?
Correlation provides for areas of interest. We already know the mechanism by which CO2 could cause a greenhouse effect, and there are measurements that back that up.
The evidence that human activity is causing the world to warm is strong and has been getting stronger over time. This is standard science, prediction and observation.
There isn't any evidence of a hiatus in the temperature trend. It does not have to break records every year for a trend to exist.
To answer your question, natural variability in the climate can cause jumps and dips that appear to slow or speed a trend. This isn't unexplainable, there are reasons behind it.
Natural variation could explain the warming too if there was sufficient evidence linking the natural changes to the trend, but there isn't.
