Tibet's thawing lakes accelerate greenhouse gas release
17+ hour, 11+ min ago (156+ words) Lakes on the Tibetan Plateau are undergoing a dramatic transformation; once stable carbon sinks, they are rapidly becoming significant sources of greenhouse gases due to climate warming'the main takeaway from anew review published in Fundamental Research. "Our review shows that…...

Li DAR'based detection of topographic modifications in medieval mountain castles and their landslide susceptibility
22+ hour, 28+ min ago (307+ words) Researchers at University of Tsukuba have developed a method to differentiate the topography of medieval mountain castles from that of natural ridges using airborne light detection and ranging (Li DAR) data. This method is expected to be useful for detecting…...

Divergent response of the westerly jet during climate transition: weakened under orbital forcing, strengthened under greenhouse gas forcing
4+ day, 21+ hour ago (189+ words) image: Conceptual diagram of the characteristics and mechanisms of the EASWJ and its influence on precipitation patterns view more The last deglaciation (~19 to 11. 5 ka BP) represents the most recent major transition in Earth's climate system, characterized by rapid warming and…...
A sinking lithospheric root raised Mongolia's Hangay Mountains
6+ day, 19+ hour ago (473+ words) A new study identifies oroclinal bending as the trigger for lithospheric foundering and surface uplift. It'opens fresh questions about how such "intracontinental" mountains may have shaped Earth's habitability over deep time, and it could help scientists better interpret similar mountain…...
