Collapse of West Antarctic ice sheet is still preventable—if we act fast to keep future warming in check
Credit: Unsplash/CC0 Public Domain Projecting when and how fast the West Antarctic Ice Sheet will lose mass due to current and future global ocean warming—and the likely impact on sea level rise and coastal communities—is a priority for climate science. We know deep water flowing towards and around Antarctica is warming, and the fringes of…

How salinity affects seasonal variability of the Makassar Strait throughflow
Seasonal variability of rainfall (colored), sea surface current field (black arrows), wind field (white arrows), and salinity in the Indonesian seas. Credit: IOCAS The Makassar Strait throughflow (MST) accounts for approximately 77% of the total volume transport of the Indonesian throughflow (ITF), and it influences mass and heat exchanges between the Indo-Pacific basin and global climate.…
