Wetlands Can Fight Climate Change Without Being Fully Flooded
Flooding bogs and meadows has been seen as a climate fix. New research from Denmark suggests a smarter strategy: keep wetlands wet, but not underwater.

Fossil-Fuel Plastics May Fuel Toxic Algae Blooms, UCSD Study Finds
A new UC San Diego study finds that petroleum-based microplastics can help drive harmful algae blooms by wiping out tiny animals that normally keep algae in check. Biodegradable plastics tested in the same experiment had a much smaller impact.

Shrubs Turn China’s Largest Desert Rim Into a Carbon Sink
Along the rim of China’s Taklamakan Desert, a 40-year experiment in planting hardy shrubs is slowing desert expansion and quietly soaking up carbon dioxide. New satellite-based research shows even one of the world’s driest places can become a measurable carbon sink.

Winter Wood Burning at Home Linked to Thousands of US Deaths
A new Northwestern University study shows that cozy winter fires come with a hidden cost: they are a major source of deadly fine particle pollution, especially in cities and communities of color. Researchers say shifting to cleaner home heating could save thousands of lives each year.

Climate Change Is Draining Monarch Butterflies’ Fuel Supply
A new University of Ottawa study shows that even a small rise in temperature can reduce the sugar content and amount of flower nectar, leaving monarch butterflies with less fat for their epic migration. The findings highlight an overlooked way climate change threatens pollinators.
