The Spin

Narrative A

Increasingly severe rainstorms and flooding are linked to global warming and climate change. Warmer weather allows air to retain more water vapor, which is why we must implement policies to cool the global temperature to save lives and billions of dollars in damage.

Narrative B

It's easy to dismiss any extreme weather event as a consequence of climate change, but in reality they're usually influenced by a myriad of factors. More research is needed before we can establish any direct causal link between the two.

Metaculus Prediction
