Some observers have blamed recent wildfires on poor forest management, while others point to climate change. In fact, a climate scientist explains, reducing fire risks means tackling both issues.
Mangrove forests grow in the tidal lagoons of tropical coastlines and they could actually benefit from climate change. Here's what that means for us.
Forest management is not a cure-all for wildfires, although it can help reduce the chances of massive burns. Making this happen will require broad collaborative efforts and more money.
Brazil's president-elect wants to roll back environmental laws, saying they hurt rural growth. But preventing Amazonian deforestation has actually made farmland more productive.

With elevated wildfire risks forecast across much of the western US this summer, here's how travelers can track local conditions, stay out of harm's way and avoid accidentally starting fires.
The illegal timber trade is a huge global business worth up to US$150 billion yearly. One way to curb it is by convincing consumers in wealthy countries that buying contraband wood products is wrong.
Europe loses as many trees to storms each year as Poland produces in timber. Until now, the models for predicting which trees are at risk have not been good enough.
New research shows that fire follows fire in the Australian Alps, and old-growth forests are less flammable.
