By integrating 13 published speleothem δ¹⁸O records from the East Asian summer monsoon (EASM) region, this study systematically analyzed the spatio-temporal characteristics of the 8.2 (8.7–7.7) and 4.2 (4.7–3.7) ka BP abrupt climate events. The results indicate that both the temporal resolution and geographical location significantly affect the ability of the stalagmite δ¹⁸O sequences to record the 8.2 and 4.2 ka BP events. During the 8.2 ka BP event, δ¹⁸O records from both northern and southern sites showed pronounced positive excursions, whereas during the 4.2 ka BP event, δ¹⁸O records from the north and south exhibited contrasting patterns. These findings provide important evidence for understanding the mechanisms of abrupt climate change and for assessing regional climate sensitivity. The related results were published in Science China: Earth Sciences, Issue 9, 2025.

As the world’s oceans warm, tropical fish species are moving into cooler waters and exploring new habitats beyond their traditional ranges. Researchers have discovered a new way to track their migration patterns by combining environmental DNA with visual surveys.

What happens when cows graze, carbon vanishes from soil, and climate change looms large? Scientists have a plan—and it involves a black, brainy material called biochar that’s transforming how we think about soil health in some of the planet’s most delicate landscapes. A powerful new study—published on July 7, 2025, in Carbon Research—has cracked the code on how to protect and even boost soil carbon in karst ecosystems, the stunning limestone-rich regions that stretch across southern China and beyond.
