In Defense of Live Carbon II: Subnational Leadership in the Fight Against Tropical Deforestation

From California to Brazil, state and provinces around the world are stepping up to fight tropical deforestation.  They need and deserve more support.

The fires burning in Brazil and the broader Amazon basin have shined a spotlight on the role of forests and land use in the climate change challenge.  For the first time in many years, the fate of tropical forests and their connection to our common future have captured the public imagination around the world.  There …

Why Stopping Deforestation May be the Hardest and Most Important Part of the Climate Change Challenge

When contemplating the enormous challenge of global climate change, it is sometimes helpful to think about a simple model of the global carbon budget (see figure below).  These admittedly reductionist schematics distinguish between sources, sinks, and reservoirs.  Fossil hydrocarbons from the geological reservoir–call this dead carbon—are extracted and burned to generate energy, emitting vast amounts …

Another Scary Election (But Not Here)

An election next Sunday has implications for the entire planet.

I hate to give you something else to freak out about in our current Age of Anxiety, but there’s a very worrisome presidential election next Sunday.

The Brazilian Deforestation Puzzle

Deforestation went down for a decade. Now it’s going up. The reasons aren’t clear.

Brazil’s rate of deforestation went down dramatically over the last ten years. It’s not completely clear why that’s happened.

Clearing Title (and Rain Forest)

On Friday, the day Waxman-Markey passed the U.S. House, another significant legal development took place — one that may also bear on climate change.  President Lula of Brazil signed a bill providing legal title to squatters on Amazon land.  Opponents argue that it will spark speculation in Amazonian property and increase deforestation.

Wildfires Cause Climate Change, Climate Change Causes Wildfires

An obvious question about the raging wildfire in Santa Barbara is whether  climate change is the cause.  While it’s impossible to blame any individual fire on increasing temperatures, we know that climate change is responsible for more frequent and more intense wildfires in the southwest.  But less obvious and at least as troubling is that …
