In Defense of Live Carbon
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 …

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. No, I haven’t completely lost it – the presidential race isn’t here, it’s in Brazil. The election pits a dangerous populist against a highly competent but colorless Establishment candidate. …

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. The trend now seems to be reversing (or at least encountering an upward blip). But it’s not clear why that’s happening either. I wish I had a clear explanation to give you. A big part of …

Recent satellite studies indicate a major decrease in the rate of deforestation in the Amazon. The journal Science reports: The Brazilian government says that a preliminary survey by a low-resolution satellite shows that deforestation in the Amazon declined by 47.5% over the past 12 months.

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.
CONTINUE READINGWildfires 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 …
