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.

1	Identify claim	31,000 dissenting scientists show there’s no expert consensus on climate change.
2	Argument structure	Premise 1: A large proportion of people with science degrees dissent against human-caused global warming. Premise 2: People with science degrees are experts on climate change. Conclusion: There is no expert agreement on human-caused global warming.
3	Inferential Intent	Deduction
4	Validity	VALID
4a	Hidden premises	NONE
5	Check premises	Premise 1 is false: magnified minority. 31,000 are 0.3% of the 10,000,000+ people with science degrees in the U.S. Premise 2 is false: fake experts. The term "scientists" covers a range of disciplines, many of which don't include expertise in climate science. 99.9% of the signatories in the Global Warming Petition Project have no expertise in climate science.
6	Status of claim	FALSE Both premises are false.
7	Summary of fallacies	Magnified minority: While 31,000 science graduates sounds like a lot, it is only 0.3% of the over 10 million people with science degrees in the United States. Fake experts: 99.9% of the signatories in the Global Warming Petition Project have no expertise in climate science.
