Discovery: Past Global Warming was more Extreme, Temperatures of 12–14C, today equivalent is around 1–2C

Ars Technica: New technique shows old temperatures were much hotter than thought. Results imply Earth may be more sensitive to carbon dioxide than previously known. In a paper recently published in Science, Professor Nele Meckler of the University of Bergen and colleagues argue that the climate between around 35 and 60 million years ago may have been…

Study: CO2 today enough to raise sea level by 20M

An international team of scientists, from Texas A&M University, the University of Southampton and the Swiss University ETH Zürich, led by the University of St Andrews, published their findings in the study, Atmospheric CO2 over the Past 66 Million Years from Marine Archives. The international team pulled together data collected over the last 15 years using high-tech laboratory techniques.  The combined data spans the…

Extinction Events in Earth History and Today

Flood basalts and mass extinctions – ancient hyperthermals as analogs for anthropogenic climate change.  Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1]  Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…

CO2 May Make Earth +10-15ºC Hotter, Like Early Paleogene

University of Bristol: A new study led by scientists at the University of Bristol has warned that unless we mitigate current levels of carbon dioxide emissions, Western Europe and New Zealand could revert to the hot tropical climate of the early Paleogene period – 56-48 million years ago. The Atlantic: They were strange days at…

Hydrological Implications during Abrupt Climate Change

Researchers studying a rapid global warming event, around 56 million years ago, have shown evidence of major changes in the intensity of rainfall and flood events. The findings indicate some of the likely implications should current trends of rising carbon dioxide and global warming continue. https://scienmag.com/new-research-indicates-likely-hydrological-implications-of-rapid-global-warming

Dan Lunt: Past climates and climate sensitivity #DeepTime #Reconstruction #3DEdition

To curiosity-driven scientist Dan Lunt, understanding the past climate of our Earth (from the scorching greenhouse of the mid-Cretaceous, to the frozen wastes of the last ice age) is of fundamental interest.
