RUDN University scientist showed global warming effect on greenhouse gas emissions in paddy soils
A soil scientist from RUDN University studied the decomposition of organic matter in rice paddies--the sources of CO2 and methane emissions. Both gases add to the greenhouse effect and affect climate warming in subtropical regions. The emissions increase when the roots of plants influence microbial communities in the soil. This influence, in turn, depends on temperature changes. Therefore, climate warming can lead to more greenhouse gas emissions. (2020-12-24)

Study suggests great earthquakes as cause of Arctic warming

Pandemic and forthcoming stimulus funds could bring climate targets in sight -- or not
The lockdowns that resulted from the COVID-19 pandemic have reduced greenhouse gas emissions. However, in the recovery phase, emissions could rise to levels above those projected before the pandemic. It all depends on how the stimulus money that governments inject into their economies is spent. A team of scientists, led by Dr. Yuli Shan and Professor Klaus Hubacek, University of Groningen, has quantified how different recovery scenarios may affect global emissions and climate change.

How nearby galaxies form their stars
How stars form in galaxies remains a major open question in astrophysics. A new UZH study sheds new light on this topic with the help of a data-driven re-analysis of observational measurements. The star-formation activity of typical, nearby galaxies is found to scale proportionally with the amount of gas present in these galaxies. This points to the net gas supply from cosmic distances as the main driver of galactic star formation. (2020-12-21)

Infrastructure key to balancing climate and economic goals in developing countries
Developing nations have an opportunity to avoid long-term dependence on fossil fuel-burning infrastructure as they move toward economic stability, even if they are slow to cut carbon emissions, say the authors of a new paper. Countries with low per capita incomes can keep their contributions to global warming to 0.3 degrees Celsius with careful foresight and planning, urge Carnegie's Lei Duan and Ken Caldeira with Juan Moreno-Cruz of the University of Waterloo.

A no-meat diet everywhere will not solve the climate crisis
Scientists argue Authors further argue that a singular focus on negative livestock-related environmental impacts ignores the critical but more positive role livestock play in ecosystem services, income and asset provision or insurance in low- and middle-income countries.
