NPG Paper of the Month: “Comparing estimation techniques for temporal scaling in palaeoclimate time series”

The NPG paper of the month of July was awarded to Comparing estimation techniques for temporal scaling in palaeoclimate time series by Raphaël Hébert, Kira Rehfeld and Thomas Laepple (https://doi.org/10.5194/npg-28-311-2021). Raphaël Hébert is currently a post-doctoral researcher at the Alfred-Wegener-Institut in Potsdam (Germany) in the Earth System Diagnostics group of Thomas Laepple, where he a ...[Read More]

Exploring the multistable and multiscale climate system via noise

Could our present day “warm” climate turn into a frozen fully glaciated one, as if the whole Earth is a huge “snowball”? That was a question put forward independently by Mikhail Budyko and William Sellers in the late 60s [1,2] who made a first estimate of the necessary changes of incoming solar radiation, such that either the Arctic ice sheet completely melts, or the planet gets fully frozen. Base ...[Read More]

The 2021 Nobel Prize on Physics awarded to the physics of complex systems!

The 2021 Nobel Prize on Physics awarded to the physics of complex systems!

On October 7th, the Nobel Prize in Physics 2021 was announced. It came as a stunning surprise for the Non-linear Processes and Climate communities, the recipients of this year’s award being two outstanding senior climate scientists, Klaus Hasselmann and Syukuro Manabe, and a theoretical physicist specialized in complex systems, Giorgio Parisi. For many, this award was welcomed as a long-awaited re ...[Read More]

Three reasons why Forest-Fires worsen with climate change

Three reasons why Forest-Fires worsen with climate change

The brand-new IPCC AR6 report clearly states that “Unless there are immediate, rapid and massive reductions in greenhouse gas emissions, limiting warming to around 1.5°C, or even 2°C, will be out of reach”. Although as human beings we do not perceive changes in global Earth average temperatures as a threat to our lives, the IPCC report also states that extreme weather events will worsen; actually ...[Read More]
