“The Earth has a flat shape rather than a spherical shape.”
The claim is false. Multiple independent, repeatable observations (satellite/space imagery, Earth’s consistently round shadow during lunar eclipses, horizon and latitude/star-visibility effects, and circumnavigation) confirm Earth is an oblate spheroid. The cited sources unanimously refute flat-Earth arguments; no credible evidence in the record supports a flat Earth.
“Current atmospheric CO2 levels are not unprecedented when compared to levels found throughout Earth's full geological record.”
The claim is technically accurate: multiple peer-reviewed studies confirm CO2 exceeded 1,000–2,000 ppm during earlier geological periods (e.g., Mesozoic, Eocene), well above today's ~422 ppm. However, the claim omits critical context. Current CO2 is the highest in at least 14 million years, the rate of increase is roughly 100 times faster than any known natural rise, and deep-time CO2 estimates carry large uncertainties (±500 ppm). The literal statement is defensible, but its framing can create a misleading impression that today's levels are unremarkable.
