"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.

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.

Methanethiol, dimethyl sulfide and acetone over biologically productive waters in the southwest Pacific Ocean

Methanethiol (MeSH) is a reduced sulfur gas originating from phytoplankton, with a global ocean source of ~ 17 % of dimethyl sulfide (DMS). It has been little studied and is rarely observed over the ocean. In this work, MeSH was measured at much higher levels than previously observed (3–36 % of parallel DMS mixing ratios). MeSH could be a significant source of atmospheric sulfur over productive regions of the ocean, but its distribution, and its atmospheric impact, requires more investigation.

“This bookmark gauges the depths of the human”: how poetry can help to personalise climate change

To many non-specialists, the science behind climate change can appear confusing and alienating, yet in order for global mitigation efforts to be successful it is not just scientists who need to take action, but rather society as a whole. This study shows how poets and poetry offer a method of communicating the science of climate change to the wider society using language that they not only better understand, but which also has the potential to stimulate accountability and inspire action.

#shareEGU20: planning your week of digital interaction!

Earlier this week, we announced that the new and revised schedule for #shareEGU20 has been released. If you missed that announcement you can take a look at the website for that here, it’s ok, we will wait… Now that you have had a quick look, maybe found your abstract, or session, you probably have a few questions. Over the next few weeks we will be trying to answer as many of these questions as we can, but given that taking …

The spikey end of geodynamics: The story of the echidna and plate tectonics

This week, Craig O’Neill, Associate Professor and director of the Planetary Research Center at MacQuarie University shows that not only humans are suffering from the consequences of global warming. The recent Australian bushfire season has precipitated a shift in the Australian – and the world’s – perception of the urgency of addressing climate change. With most of the east coast of the continent covered in thick smoke, many Australians were faced with reality of spending the entire season not at …

On modelers and modeling

Several studies were conducted and are ongoing where we investigate modelers, modeling decisions and modeling perceptions. Below I discuss the rationale and a summary of the (preliminary) results. Simulation models, conceptualizations of processes into a system of mathematical equations (hereafter simply referred to as models), are frequently used tools in the hydrological sciences. The literature review of Burt & McDonnell (2015)1 demonstrates the decline in fieldwork papers, and a strong increase in modelling papers in the field of runoff. So …
