Mass drowning of chicks puts emperor penguins at risk of extinction (theguardian.com)

• Premature sea ice melt leads to mass chick mortality
• Species' reproductive cycle misaligned with warming climate
• High risk of extinction due to habitat collapse

"Rapid disintegration of Antarctic sea ice is causing catastrophic breeding failure for emperor penguins. Chicks, whose feathers are not yet waterproof, are drowning when ice shelves collapse prematurely. Environmental changes threaten the species' survival as critical nesting grounds disappear."
