Summary

Story summary

A study using nearly 20 years of satellite data finds a shift in ocean color, with tropical phytoplankton declines and higher productivity in polar waters.
The migration of phytoplankton productivity could disrupt marine food chains and carbon cycling.
Glaciers in Patagonia are melting rapidly, threatening water supplies for millions.
Experts warn that a modest temperature rise could cause substantial glacier loss by 2100, underscoring the need to curb emissions.
