Step-by-step deconstruction
The table below is inspired by the simplified supplement and may differ slightly from what is shown in the GIF. This is mostly due to make the text fit into the available space which made it necessary to reword some of it. In the paper's supplement, this myth was identified as using ambiguous wording requiring a fairly complex deconstruction. Because this turned out to be difficult to clearly show in an animated GIF, the deconstruction was simplified.

Identify claim |
Scientists can’t even predict the weather next week, so how can they predict the climate years from now? |
2 |
Argument structure |
Premise 1: Weathercasters get weather predictions wrong. Premise 2: Weather and climate predictions are comparable. Conclusion: Climate predictions are unreliable. |

4 |
Validity |
LOGICALLY VALID |

Hidden premises |
NONE |
5 |
Check premises |
Premise 1 is true. Premise 2 is false and a false equivalence. This claim conflates weather and climate, which is weather averaged over time and space. The success of short-term predictions has little relevance to long-term climate predictions. |
6 |
Status of claim |
FALSE While premise 1 is true, premise 2 is wrong.
