Climate: Past, Present & Future

New metric to interpret linear trends from short time series: Trend to variability ratio (TVR)

Bramha Dutt Vishwakarma March 17, 2021

Availability of good quality data is essential to deduce meaningful information in all disciplines of science and technology. This statement is especially relevant in climate research, which is under constant scrutiny from sceptics. In order to better understand the Earth system response to the ongoing anthropogenic global warming, we require global observations of climate indicators at ver ...[Read More]

About the blog series: Life of a Climate scientist Life of a Climate Scientist is a new blog series started by the EGU Climate Division. The main focus of this series is to provide a platform for climate scientists to tell their stories of life in research. We will be covering a wide-range of subjects, from their scientific endeavors and maintaining work-life balance to challenges they have faced ...[Read More]

EGU’s Atmospheric Sciences and Climate: Past, Present & Future Divisions welcome the US back into the Paris Climate Agreement

Chloe Hill, Janina Nett, Fei Luo and Athanasios Nenes March 3, 2021

As of 19 February 2021, the US officially re-joined the Paris Climate Agreement, a landmark international accord to limit global warming by 2°C (and ideally to 1.5°C) compared to pre-industrial levels. The Paris Climate Agreement aims to bring the world together to avoid catastrophic warming that will impact us all and to build resilience to the consequences of climate change that we are already s ...[Read More]

What’s my age again? Comparing dating methods in loess

Janina Nett, Sonja Berg, Christian Zeeden and Stephanie Scheidt February 9, 2021

Figure 1: The investigated Balta Alba Kurgan loess-paleosol sequence in Romania with the partly preserved Kurgan on top (black dashed line). Sampled profiles are indicated by the white rectangles and the stratigraphically important tephra layer is highlighted in pink (adapted from [1]).

As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating, radiocarbon dating, magnetic stratigraphy, and or ...[Read More]
