The primary goal of the annual State of the Climate collection of articles is to document the weather and climate events of the most recent calendar year and put them into accurate historical perspective, with a particular focus on unusual or anomalous events.  This report states that year 2010 was notable for its globally-averaged warmth and for the far-reaching impacts related to signifi

A primer on extreme weather, the paper explains that the recent surplus of extreme weather events is part of a longer trend of rising extremes that reveals a pattern of increasing risk as the planet warms.

The question of whether biofuels help mitigate climate change has attracted much debate in the literature. Using a global computable general equilibrium model that explicitly represents land-use change impacts due to the expansion of biofuels, this study attempts to shed some light on this question.

This is a comprehensive analysis of actions underway in the world’s megacities to address climate change. It not only underscores what cities have done to date, but also what they can do now and in the future as local leaders, and as a collective, to have a significant global impact.

As the impacts of climate change escalate, efforts to develop new technologies and new approaches to reducing emissions are promoted. One proposal is to sequester carbon in soils using biochar. Biochar is essentially fine grained charcoal.

Deforestation and forest degradation have been occurring for thousands of years. Both deforestation, which completely removes the forest canopy, and degradation, which maintains the canopy but causes losses of carbon, are important sources of global warming pollution, as well as threats to biodiversity and to the livelihoods of forest peoples.

The purpose of these guidelines is to update and expand the original guidelines on protected areas legislation published in 1980 and to reflect new developments and emerging issues.

Carbon Fat Cats 2011 sets out the analysis of those companies profiting most from Europe’s Emissions Trading Scheme (ETS). The results matter because of their bearing on a crucial debate being held in Europe and the wider world – a debate about how to respond to profound challenges created by the economic dependence on fossil fuels, in particular the threat to a stable climate.

The purpose of the paper is to review the recent empirical literature relating to the quantification and valuation of the human health impacts of air pollution, hazardous chemicals, and unsafe water and

For five years, Forest Trends’ Ecosystem Marketplace and Bloomberg New Energy Finance have published the State of the Voluntary Carbon Markets Reports to shed light on trading volumes, credit prices, project types, locations, and the motivations of buyers in this market.
