Between 2000 and 2020, 42% of tree lines around the world crept upward, largely because of climate change. But 25% moved downhill, seemingly because of factors such as land use changes and wildfires.

Location, Location, Location: The “Where” of Reforestation May Matter More Than the Extent
A new study finds that focusing reforestation efforts in strategic locations, such as the tropics, can accomplish global cooling levels comparable to less strategic reforestation efforts covering twice as much area.
An Art-Science Partnership Offering New Views of Dynamic Landscapes
The immersive and interactive WILDLAND exhibition allowed the public—and the exhibition’s creators—to explore connections among water, trees, fire, and other natural and human-made materials expressed across a spectrum of artistic approaches.
Trees Shed Their Leaves to Adapt to Droughts
The browning or loss of tree leaves that can be observed during droughts may be a coping mechanism to deal with dry circumstances by avoiding additional water stress.
Glass Sand Grows Healthy Mangroves
In places with lots of glass waste, sand made from recycled material could be another tool in the coastal restoration toolbox.
California Schools Are Feeling the Heat
Even though trees help keep children safe from the Sun, some school districts have lost 25% of their tree canopy in just 4 years.
As CO2 Levels Rise, Old Amazon Trees Are Getting Bigger
New data show resilience among the rainforest’s giants, though scientists warn that nutrient limits and rising heat could end the trend.
How Plant-Fungi Friendships Are Changing
A new framework shows how much carbon plants allocate to their endosymbionts and how that amount might change in the face of warming soil and rising carbon dioxide levels.
Old Forests in the Tropics Are Getting Younger and Losing Carbon
New research quantifying the global impact of forest age transitions found that 140 million tons of aboveground carbon are lost per year because of old-growth forests being replaced by younger stands.
Droughts Sync Up as the Climate Changes
A new study reconstructs roughly 800 years of streamflow history in India’s major rivers, showing an increase in synchronous drought linked to anthropogenic climate change.
