Understanding the Global Temperature II
via Scottish Sceptichttp://scottishsceptic.co.uk
Recap: in the last article, I showed that the satellite record, which is our most reliable indication of global temperatures, is most like the sea temperature record and least like the land based record. I had a go at trying … Continue reading →

Understanding the Global Temperature “discrepancies”
via Scottish Sceptichttp://scottishsceptic.co.uk
In my last post I created a reconstruction of global temperature over 350 years which I show below: And as I said in the article, I was confused why the UAH 6 (red) had not warmed as much as the … Continue reading →

Temperature Reconstruction
via Scottish Sceptichttp://scottishsceptic.co.uk
Recently there’s been a couple of times I needed a global temperature but for obvious reasons I do not think it would be ethical to use reconstructions that I feel are fraudulent. This has left only UAH6 (which is the … Continue reading →

Permian-Triassic boundary extinction was due to ice age cold, not global warming as claimed by alarmists.

Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species disappeared and, up until now, scientists have linked this extinction to a significant rise in Earth temperatures. But researchers from the University of Geneva (UNIGE), Switzerland, working alongside the University of Zurich, discovered that this extinction took place during a short ice age which preceded the global climate warming. It’s the first time that the various stages of a mass extinction have been accurately understood and that scientists have been able to assess the major role played by volcanic explosions in these climate processes. This research, which can be read in Scientific Reports, completely calls into question the scientific theories regarding these phenomena, founded on the increase of CO2 in the atmosphere, and paves the way for a new vision of Earth’s climate history.
Teams of researchers led by Professor Urs Schaltegger from the Department of Earth and Environmental Sciences at the Faculty of Science of the UNIGE and by Hugo Bucher, from the University of Zürich, have been working on absolute dating for many years. They work on determining the age of minerals in volcanic ash, which establishes a precise and detailed chronology of Earth’s climate evolution. They became interested in the Permian-Triassic boundary, 250 million years ago, during which one of the greatest mass extinctions ever took place, responsible for the loss of 95% of marine species.
