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.

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.

“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.

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.

Changing suspended sediment in United States rivers and streams: linking sediment trends to changes in land use/cover, hydrology and climate

Between 1992 and 2012, concentrations of suspended sediment decreased at about 60 % of 137 US stream sites, with increases at only 17 % of sites. Sediment trends were primarily attributed to changes in land management, but streamflow changes also contributed to these trends at > 50 % of sites. At many sites, decreases in sediment occurred despite small-to-moderate increases in the amount of anthropogenic land use, suggesting sediment reduction activities across the US may be seeing some success.

Travels in Geology: A World Turned Upside Down

Travels in Geology: A World Turned Upside Down

Last weekend, with a strict, stay-at-home coronavirus order looming on the horizon, I decided to practice social distancing using a tried-and-true method: escaping on a hike. Since I’m currently in Colorado, I chose to climb North Table Mountain, the remnant of an ancient basalt lava flow located on the outskirts of Denver. Locally this mesa, along with its twin located a short distance to the south, are popular hiking, biking and rock-climbing areas boasting great views from their wide, flat …

Creating Value for Safety: from earthquake preparedness to pandemic outbreak response

Creating Value for Safety: from earthquake preparedness to pandemic outbreak response

Disasters happen world-wide, almost every day. If you are an earthquake seismologist (or engineer), chances are good that seismic hazard is in your daily diet. Developing an earthquake scenario, estimating the seismic hazard, assessing the risk, regulating the land use: we usually conduct these tasks to limit the socio-economic impact of a seismic event. However, when planning and coordinating the emergency response, many more facets come into play. Initial indifference, denial, disbelief, then awareness, finally acceptance, and abnegation. A succession …

Life of a scientist: When fieldwork doesn’t go to plan…

Climate research questions tend to focus on the future. What will global temperature be in 2100? Will extreme weather events become more frequent? When will sea level rise render coastal homes uninhabitable? But our understanding of climate processes first comes from observing the past: palaeoclimatology. To get these records, scientists often go on fieldwork to collect samples. But what happens when fieldwork isn’t successful? In this week’s post, Isobel Rowell tells us about her latest fieldwork, and what she learnt …
