Q&A: Authors discuss addressing the crisis of species loss
No oncologist would wait for a patient's cancer to spread before treating it. Similarly, waiting to detect the potential loss of a species across all its known habitats means interventions are often too late to turn the tide of extinction, according.....»»
Pollen affects cloud formation and precipitation patterns, researchers find
Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and minus 25 degrees Celsius......»»

Atmospheric lidar instrument on climate satellite enhances understanding of aerosols and clouds
The atmospheric lidar ATLID, the last of four instruments on board the EarthCARE satellite launched in May, has now been successfully put into operation. The joint mission of the European Space Agency (ESA) and the Japanese Space Agency (JAXA) is des.....»»
Scientists discover nonstomatal control of water loss in critical crops
Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism—tiny pores known as stomata......»»
Unveiling soil moisture patterns with advanced navigation tech
A pioneering method for soil moisture retrieval using satellite navigation systems has been introduced, significantly boosting the accuracy and efficiency of global data collection. The research, published in the journal Satellite Navigation, tackles.....»»
Researchers use training model to map planted and natural forests via satellite image
While planting trees may seem like an easy win to combat climate change, planted forests often encroach on natural forests, wetlands, and grasslands. This can reduce biodiversity, disturb the natural environment, and disrupt carbon and water cycling......»»
