On Earth Day two weeks ago, 171 countries officially signed the Paris Agreement on climate change. In doing so, they agreed to the long term goal of ending humanity’s damage to the climate—that is, reducing our emissions of global warming pollution to zero—in the second half of this century. One encouraging part of the ongoing scientific discussion about how to achieve this ambitious goal, is that we’re finally starting to take seriously the impact of what people eat. Three recent studies show that it makes a big difference, to the climate as well as to our health.

UCS has just created a new set of web pages summarizing the latest scientific information on the drivers of tropical deforestation.

And some of these new studies have changed scientists’ minds about the problem in important ways. Read more >

Shortly before I arrived here in Paris for the climate negotiations, Brazil’s National Institute for Space Research released the annual figure on Amazon deforestation for 2014–2015. This number comes out each year about this time, and is eagerly awaited as a sign of whether the dramatic progress that Brazil made over the past decade in reducing deforestation by three-fourths, is continuing.
