A recent global assessment by University of Hamburg's CLICCS identifies key conditions for sustainable climate adaptation, including developing measures together with local populations. The study also emphasizes the importance of social movements, climate litigation, and achieving higher levels of social justice in driving change.
Researchers developed a new type of ocean model that can simulate the transport, storage, and turnover of carbon in the global coastal ocean. The model shows that intense plankton growth is key to enhanced CO2 uptake in coastal oceans, which could strengthen with ongoing CO2 emissions.
Research by Dr. Armineh Barkhordarian finds that Arctic marine heatwaves will become a regular occurrence, with average temperatures rising 2.2 degrees Celsius above seasonal norms. The study suggests that annual heatwaves will be the norm, with significant negative impacts on the ecosystem.
A recent study reveals that climate adaptation efforts globally are largely isolated and uncoordinated, with a lack of cohesion in task distribution among various actors. Comprehensive, just, and forward-thinking adaptation requires involvement from multiple groups, including governments, organizations, and individuals.
Researchers conclude that social changes, such as consumption patterns and climate protests, are crucial in meeting the 1.5-degree goal, but current efforts are insufficient. A new approach to adaptation is necessary to address the impacts of global warming.
Researchers analyzed observational data from a major field campaign in 2020 and found that trade-wind clouds' contribution to climate warming has been overestimated. The study shows that the clouds are more resilient to global warming than previously thought, which can improve the accuracy of future climate projections.
A study by Dr. Armineh Barkhordarian confirms a systematic warming pool in the Pacific caused by human activities, leading to increased frequency and intensity of local marine heatwaves. The region has experienced 31 marine heatwaves over the past 20 years, compared to just nine between 1982 and 1999.
The end-Permian mass extinction was characterized by a 10-degree climate warming, with 75% of organisms going extinct on land and 90% in oceans. Machine learning analysis reveals that declining oxygen levels, rising water temperatures, and ocean acidification were the key factors in organism survival or extinction.
Scientists at the University of Hamburg have calculated for the first time the future balance of Arctic coastal erosion, which increases by up to three meters per year with each degree of temperature increase. A shift towards greater sustainability could slow this process, but it's unlikely to stop land loss entirely.
A team of scientists has redefined indicators for biological diversity, analyzing ecosystem and species distribution. They found that areas with many species don't always have high biodiversity, and some protected areas may not be effectively conserving species and ecosystems.
A new study suggests that deep decarbonization by 2050 is currently not plausible, highlighting the need for more ambitious climate action. The Hamburg Climate Futures Outlook examines social drivers and technological advancements to determine which climate futures are possible.
Physicists have long wondered if crystals can form in time instead of space. Now, researchers have successfully created a time crystal in a high-temperature superconductor by applying a laser. This breakthrough establishes a new state of matter and opens up new possibilities for designing quantum materials on demand.
Researchers have successfully observed Josephson oscillations in a 2D Fermi gas, providing new insights into the nature of strongly correlated quantum systems and their potential to revolutionize power distribution through room temperature superconductors.
A new study suggests that the Arctic Ocean will likely be ice-free in summer due to high future CO2 emissions. However, rapid reductions in CO2 emissions could lead to occasional ice-free summers even before 2050. The study's findings highlight humanity's impact on the Arctic ecosystem and climate.
Researchers found that horse herds can significantly slow the loss of permafrost soils, preserving 80% of them until 2100. The approach, inspired by a Russian experiment, uses large herbivores to manipulate snow cover and reduce freezing temperatures.
Scientists developed new theory capturing second sound phenomenon in quantum liquids, showing it can be faster than first sound. Theoretical approach uses squeezed-field path integral description, applicable to various phenomena at quantum-classical physics interface.
Researchers from University of Hamburg discovered that solid rock exhibits fluid behavior during massive impacts, forming craters in just minutes. The findings support the acoustic fluidization hypothesis and have significant implications for understanding large impact crater formation across our solar system.
Researchers at the University of Hamburg disrupt crystalline order in a quantum system using light pulses, restoring superfluidity. The study demonstrates a fundamental mechanism for controlling phase transitions in many-body systems via light control.
Researchers at the University of Hamburg have developed a new transistor concept based on metal nanoparticles, which exhibit energy gap properties due to Coulomb repulsion. This approach enables scalable synthesis, high-quality thin films and flexible devices with adjustable electrical characteristics.
Scientists have successfully demonstrated electronic spin effects in wet-chemically produced nanocrystals, opening doors to more efficient and powerful electronics. The Rashba effect, a phenomenon normally not observed due to high crystal symmetry, was controlled by varying layer thickness, light used, and electric fields.
Physicists harness superradiant state to study dynamic phase transitions, mirroring water cycle and Higgs field condensation. The experiment introduces a controlled coupling to the environment, expanding scope for understanding imperfect crystallization and defects.
