(University of Oldenburg ) The depths of the Black Sea store comparatively large amounts of organic carbon. A research team led by scientists from the University of Oldenburg, Germany, has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit in the scientific journal Science Advances. This negative feedback in the climate system could counteract global warming over geological periods.
Improving resource efficiency in manufacturing processes is as important as reducing the transport industry’s greenhouse gas emissions; Setting high emission reduction targets is the only way towards a net-zero greenhouse gas economy; Reducing the industry’s reliance on fossil fuels, recycling…
Even without new fossil fuel projects, global warming will still exceed 1.5℃. But renewables might make it possible – The Conversation AU
The International Energy Agency (IEA) last month made global headlines when it declared there is no room for new fossil fuel investment if we’re to avoid catastrophic climate change. However, our new research suggests the horse may have already bolted….
(Helmholtz-Zentrum Dresden-Rossendorf) Not only the 11-year cycle, but also all other periodic solar activity fluctuations can be clocked by planetary attractive forces, a conclusion drawn by Dr. Frank Stefani and colleagues at HZDR and the Institute of Continuous Media Mechanics in Perm, Russia. With new model calculations, they are proposing a comprehensive explanation of known sun cycles for the first time. They also reveal the longest fluctuations in activity over thousands of years as a chaotic process.
(Ruth Francis Strategic Consulting) Every five years, the UNESCO Science Report provides an update of trends in science governance. Written by 70 authors from 52 countries, it aggregates data on spending, personnel, scientific publications and patents. The latest edition tracks progress towards the UN’s 2030 Sustainable Development Goals and the rapid progress of the Fourth Industrial Revolution. It also tracks the impact of the COVID-19 pandemic on global research and innovation.

Hindu Kush Himalayan mountain ranges could lose up to two-third of its ice by 2100, according to UNDP
Implementation of these ambitions would require enhanced institutional capabilities through policy amends, behavioural change and technology support

(Earth Institute at Columbia University) A new global analysis says that greenhouse-gas emissions from food systems have long been systematically underestimated–and points to major opportunities to cut them. The authors estimate that activities connected to food production and consumption produced the equivalent of 16 billion metric tons of carbon dioxide in 2018–one third of the human-produced total, and an 8 percent increase since 1990.
