Thallium isotopes can be used to reconstruct marine oxygenation (a proxy for this) since the isotope composition of the ocean is heavily influenced by the formation of manganese oxide minerals that form under oxygenated marine conditions. Here’s a good review of the Tl isotope proxy (2/7) 🧪⚒️

New research shows that global warming during the Paleocene-Eocene Thermal Maximum was amplified by widespread forest fires and soil erosion, which occurred within as little as a few centuries after a huge amount of carbon dioxide entered the atmosphere 🔥 Read the full story: buff.ly/cEMbgQO

Ancient global warming was amplified by widespread forest fires and soil erosion
56 million years ago the Paleocene-Eocene Thermal Maximum (PETM), a period of rapid global warming, occurred. Within the span of a couple of millennia, temperatures rose by 5 degrees, triggered by a huge release of carbon. Due to its likeness to present-day warming, the PETM is often used to test the long-term environmental response to large-scale perturbations, making it a very scientifically valuable climatic event to study.
