Precise data for improved coastline protection
Researchers working under the leadership of the Technical University of Munich (TUM) have conducted the first precise and comprehensive measurements of sea level rises in the North Sea and the Baltic Sea. A new method now makes it possible to determine sea level changes with millimeter accuracy even in coastal areas and in case of sea ice coverage. This is of vital importance for planning protective measures.
For the billions of people who live in coastal areas, rising sea levels driven by climate change can pose an existential threat. “To protect people and infrastructure – for example by building flood protection structures, securing ports or making dikes higher – we need reliable forecasts on sea level trends,” explains Prof. Florian Seitz, the Director of the German Geodetic Research Institute (DGFI-TUM) at TUM. “However, this requires precise data with high spatial resolution. And until now, the required wide

A catastrophic drop in atmospheric ozone levels around the tropics is likely to have contributed to a bottleneck in the human population around 60 to 100,000 years ago, an international research team has suggested. The ozone loss, triggered by the eruption of the Toba supervolcano located in present-day Indonesia, might solve an evolutionary puzzle that scientists have been debating for decades.
“Toba has long been posited as a cause of the bottleneck, but initial investigations into the climate variables of temperature and precipitation provided no concrete evidence of a devastating effect on humankind,” says Sergey Osipov at the Max Planck Institute for Chemistry, who worked on the project with KAUST’s Georgiy Stenchikov and colleagues from King Saud University, NASA and the Max Planck Institute for Chemistry.
New research by LLNL scientists shows that satellite measurements of the temperature of the troposphere (the lowest region of the atmosphere) may have.
