A new study reveals corals must be within only a few metres of each other to successfully reproduce, leaving them vulnerable in a warming world.

In a study published in Science China Earth Sciences, researchers present findings showing that plant DNA metabarcoding from lake sediments provides a higher resolution and more accurate depiction of local vegetation on the Tibetan Plateau than traditional pollen analysis, with a broader range of species detected.

On February 2, 1887, residents of Punxsutawney Pennsylvania consulted a large rodent regarding the arrival of spring, marking the first official celebration of Groundhog Day. Our ability to predict the timing of seasons hasn’t improved much since then, but a new study is set to make seasonal forecasting a lot more reliable.

Achieving net-zero CO₂ emissions is the current main focus of China’s carbon neutrality goal. However, non-CO₂ greenhouse gases (GHGs) are more powerful climate forcers, making their emission reduction an opportunity to rapidly mitigate future warming. This study evaluates non-CO₂ mitigation potentials, costs and climate benefits in the context of China’s carbon neutrality goals. The findings indicate that mitigation technologies can largely reduce fluorinated gas emissions from industrial sectors, but long-term non-CO₂ reductions of energy sector activities rely heavily on fuel switching. Furthermore, the cumulative costs of deploying non-CO₂ mitigation technologies are projected to be less than 10% of the total costs of achieving carbon neutrality from 2020 to 2060. If non-CO₂ mitigation measures are included in the overall mitigation portfolio, the benefits of avoided warming would by far outweigh the total mitigation cost increase.

Caio Canella Vieira, a researcher for the Arkansas Agricultural Experiment Station and assistant professor of soybean breeding, is leading a new project to develop resilient soybean plants and decrease damages from southern root-knot nematodes. The microscopic worms cause an estimated $160 billion in damages globally each year. Vieira was awarded a $791,000 grant by the National Insitute of Food and Agriculture to develop soybean plants with resistance to the pest as it encrouches northward with climate change.
