"Snake" is crawling through the sea ice

The Antarctica Factor: model uncertainties reveal upcoming sea-level risk

  • Press release
  • 14 February 2020

Sea-level rise due to ice loss in Antarctica could become a major risk for coastal protection even in the near term, scientists say. Within this century already, due to Antarctica alone, global sea level might rise up to three times as much as it did in the last century, according to research published in the EGU journal Earth System Dynamics.

Methane emissions from the Munich Oktoberfest

We demonstrate for the first time that large festivals can be significant methane sources, though they are not included in emission inventories. We combined in situ measurements with a Gaussian plume model to determine the Oktoberfest emissions and show that they are not due solely to human biogenic emissions, but are instead primarily fossil fuel related. Our study provides the foundation to develop reduction policies for such events and new pathways to mitigate fossil fuel methane emissions.

Deconvolution of boundary layer depth and aerosol constraints on cloud water path in subtropical stratocumulus decks

Cloud water content and the number of droplets inside clouds covary with boundary layer depth. This covariation may amplify the change in water content due to a change in droplet number inferred from long-term observations. Taking this into account shows that the change in water content for increased droplet number in observations and high-resolution simulations agrees in shallow boundary layers. Meanwhile, deep boundary layers are under-sampled in process-scale simulations and observations.

Back to the future II: tidal evolution of four supercontinent scenarios

We have confirmed that there is a supertidal cycle associated with the supercontinent cycle. As continents drift due to plate tectonics, oceans also change size, controlling the strength of the tides and causing periods of supertides. In this work, we used a coupled tectonic–tidal model of Earth’s future to test four different scenarios that undergo different styles of ocean closure and periods of supertides. This has implications for the Earth system and for other planets with liquid oceans.

Scaling carbon fluxes from eddy covariance sites to globe: synthesis andevaluation of the FLUXCOM approach

We test the approach of producing global gridded carbon fluxes based on combining machine learning with local measurements, remote sensing and climate data. We show that we can reproduce seasonal variations in carbon assimilated by plants via photosynthesis and in ecosystem net carbon balance. The ecosystem’s mean carbon balance and carbon flux trends require cautious interpretation. The analysis paves the way for future improvements of the data-driven assessment of carbon fluxes.

#shareEGU20: let’s get creative and share EGU art!

Due to the ongoing coronavirus outbreak, EGU has made the decision to cancel this year’s physical General Assembly in Vienna and instead offer a partial alternative meeting online, called #shareEGU20. Over the next few weeks in the run up to #shareEGU20, which will be held from the 4 – 8 May 2020, we will be posting regular updates and information about how to get involved, what EGU can offer during this week and how to find each other. We know …

Does debris cover offset glacier retreat in the Greater Caucasus?

Does debris cover offset glacier retreat in the Greater Caucasus?

In this week’s blog, Levan Tielidze tells us about supra-glacial debris cover change for the Greater Caucasus. His recent study indicates more than a doubling in the area of supra-glacial debris cover for the Elbrus Massif‘s glaciers from 1986 to 2014, the largest glacierized massif in the whole region. Glaciers on the western slope of the Elbrus Massif are affected by avalanches and thus are partially debris-covered. But the most significant increase of supra-glacial debris cover occurred on the eastern …
