New study to uncover how climate change and tectonics drove evolution in East Africa

The whale fossil represents a massive change from the Miocene to today in Kenya’s Turkana Basin, as the fossil of this sea animal was originally found 740 miles inland and 620 meters in elevation – an indication perhaps of a transformed geological and ecological landscape with the open-ended question: Why was the whale there?

Ancient genomes suggest woolly rhinos went extinct due to climate change, not overhunting

he extinction of prehistoric megafauna like the woolly mammoth, cave lion, and woolly rhinoceros at the end of the last ice age has often been attributed to the spread of early humans across the globe. Although overhunting led to the demise of some species, a study appearing August 13 in the journal Current Biology found that the extinction of the woolly rhinoceros may have had a different cause: climate change.

McIntyre on Kaufman et al 2020

I was curious as to why their new Antarctic reconstruction was so dramatically different from PAGES2K only seven years ago – a question that both they and reviewers ought to have thought about. Difference arises mainly from one catastrophic error and 2 implausible new series.

Exact climate data from the past

Corals precipitate their calcareous skeletons (calcium carbonate) from seawater. Over thousands of years, vast coral reefs form due to the deposition of this calcium carbonate. During precipitation, corals prefer carbonate groups containing specific variants of oxygen (chemical symbol: O).
