Global evaluation of the “dry gets drier, and wet gets wetter” paradigm from a terrestrial water storage change perspective

Although the “dry gets drier, and wet gets wetter (DDWW)” paradigm is prevalent in summarizing wetting and drying trends, we show that only 11.01 %–40.84 % of the global land confirms and 10.21 %–35.43 % contradicts the paradigm during 1985–2014 from a terrestrial water storage change perspective. Similar proportions that intensify with the increasing emission scenarios persist until the end of the 21st century. Findings benefit understanding of global hydrological responses to climate change.

Upwelled plankton community modulates surface bloom succession and nutrient availability in a natural plankton assemblage

We investigated how different deep water chemistry and biology modulate the response of surface phytoplankton communities to upwelling in the Peruvian coastal zone. Our results show that the most influential drivers were the ratio of inorganic nutrients (N:P) and the microbial community present in upwelling source water. These led to unexpected and variable development in the phytoplankton assemblage that could not be predicted by the amount of inorganic nutrients alone.

The IPCC Sixth Assessment Report WGIII climate assessment of mitigation pathways: from emissions to global temperatures

Assessing hundreds or thousands of emission scenarios in terms of their global mean temperature implications requires standardised procedures of infilling, harmonisation, and probabilistic temperature assessments. We here present the open-source “climate-assessment” workflow that was used in the IPCC AR6 Working Group III report. The paper provides key insight for anyone wishing to understand the assessment of climate outcomes of mitigation pathways in the context of the Paris Agreement.

Join the Life-Work-Balance activities at EGU23!

Dear fellow scientists (and readers joining us at EGU23!), It’s us again, the “Life-Work-Balance” group of EGU. We are a team of scientists organizing various events related to life-work-balance during the EGU General Assembly and would like to share our experience with you. For this year’s General Assembly we are organizing several short courses and pop-up events to offer some guidance for balance in academia. Hope you can join us at one or several of these events. We are looking …

3 Reasons to engage in early career networks

There are several early career groups, which are affiliated with cryosphere-based research in one way or another. APECS (Association of Polar Early Career Scientists) is an international network that is present during many occasions and events in the world of polar research. Have you ever wondered why busy early career researchers (ECRs) use their time also for volunteering in such groups? Today, three members from the board of APECS Germany will give you their reasons why. “Learning by doing” – …

What you can do to ensure a safe and inclusive EGU23!

It is true that academic gatherings like scientific conferences can offer great opportunities for career advancement, such as building stronger networks, highlighting your research, and finding new opportunities for collaboration. Unfortunately, many conferences are not equally inclusive to all (see the image below) and can pose as unsafe environments for presenters and participants. With EGU23 only two weeks away, here are some of the ways you can stay vigilant of and report any unethical behaviour at the conference. We need …
