When weather extremes meet climate change: how do scientists attribute single events to climate change?

When weather extremes meet climate change: how do scientists attribute single events to climate change?

One of the main new points of the IPCC reports AR6 with respect to the previous ones is the increased confidence that global climate change induced by anthropogenic emissions is critically affecting the dynamics of weather extremes. For summer, and specifically over Europe, the AR6 report states that we are already observing prolonged periods of extremely warm conditions with increased droughts bo ...[Read More]

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

The Indian Ocean Geoid Low is an enigmatic phenomenon in geodynamics. Many brain-storming hypotheses have been proposed in the last few decades to explain this geoid low. One popular idea argues that the high density lower mantle slabs contribute to this geoid low. Recent discoveries have shown that low-density anomalies from the African LLSVP region could have a more substantial influence on crea ...[Read More]

TS Must-Read – Caine et al., 1996 Fault zone architecture and permeability structure

Caine et. al. (1996) is a cornerstone paper which describes, compares and quantifies brittle fault zones and their permeability (fluid flow) properties from observations. Doing so, the paper initiates the accumulation of information on the permeability of brittle fault zones described previously (Randolph and Johnson 1989; Scholz 2019; Byerlee 1993). The study begins by defining fault zones as com ...[Read More]

Putting some pieces of the climate puzzle together, a chat with Jakob Zscheischler

The climate on our home planet is changing, and the effects of this change affect all of us at different levels starting from an enhancement of extreme weather events, a severe natural hazard. Climate change has several drivers, which in turn have complex interactions. Thus, it should not surprise us if climate science is a complex and interdisciplinary discipline with numerous players and great p ...[Read More]

The Sassy Scientist – The Nonsense Of Open Research

Enzo submitted his manuscript for review at one of those well-known, Earth science-niche journals. However, shortly thereafter he received an email by his editor that it was rejected. Reason being that not enough research was added in the manuscript. Furious, he bellows: When is my research open enough to be published? Dear Enzo, I know, right? It seems that over the past few years the need to giv ...[Read More]

Earthquake Watch: Woods Point, Australia – September, 2021

Dee Ninis, an Earthquake Geologist and Seismologist from the Seismology Research Centre of Australia, outlines the 22 September 2021 Mw5.9 Woods Point, Australia earthquake for the first Earthquake Watch of the year. On 22 September, 2021 at 09:15 AEST (2021-09-21 23:15 UTC) a moderate earthquake of Mw 5.9 near Woods Point, Victoria, shook southeast Australia. Felt reports were received from as fa ...[Read More]

A place called home?

Welcome to Kongsfjorden in Svalbard. The front of the glaciers terminating into the sea is an ecological hotspot, home to many marine animals, like kittiwakes, who love to hunt here. They feed on small fish and shrimp, which at marine-terminating glacier fronts are brought to the surface by upwelling glacial meltwater. Retreating glaciers lose their contact with the ocean As the planet warms these ...[Read More]
