Conceptual model can explain how thunderstorm clouds bunch together
Understanding how the weather and climate change is one of the most important challenges in science today. A new theoretical study presents a new mechanism for the self-aggregation of storm clouds, a phenomenon, by which storm clouds bunch together in dense clusters. The researcher used methods from complexity science, and applied them to formerly established research in meteorology on the behavior of thunderstorm clouds.

New evidence shows rapid response in the West Greenland landscape to Arctic climate shifts
Evidence from an Arctic ecosystem experiencing rapid climate change reveals surprisingly tight coupling of environmental responses to climate shifts. Links between abrupt climate change and environmental response have long been considered delayed or dampened by internal ecosystem dynamics, or only strong when climate shifts are large in magnitude. The research team presents evidence that climate shifts of even moderate magnitude can rapidly force strong, pervasive environmental changes across a high-latitude system.

How climate change affects crops in India
Researchers found that the yields from grains such as millet, sorghum, and maize are more resilient to extreme weather in India; their yields vary significantly less due to year-to-year changes in climate and generally experience smaller declines during droughts. But yields from rice, India's main crop, experience larger declines during extreme weather conditions.
