MisleadingNo evidence for a significant influence of volcanoes or solar variability on recent climate change contrary to Judith Curry’s claims in PragerU video
Claim:
Climate scientists disagree about how much warming is associated with our emissions and whether this warming is larger than natural climate variability from the sun and volcanic eruptions

IncorrectCarbon isotopes do not show that humans’ climate impacts are too small to notice, despite the Daily Sceptic’s inaccurate claim
Claim:
Human-caused carbon emissions’ effect on climate is ‘non-discernible’. Measurements of carbon isotope ratios in atmospheric CO2 indicate that it is the recent expansion of a more productive biosphere that has led to increased CO2 concentrations in the atmosphere.

MisleadingOptimal atmospheric CO2 for dinosaurs and plants is harmful for humans; current concentration is higher than Homo sapiens have ever experienced
Claim:
High CO2 was fine for the dinosaurs and high CO2 benefits plants today in greenhouses, so more CO2 can’t be bad for humans
