The assumption that plants can absorb excessive fossil fuel emissions containing carbon dioxide because they need the gas in order to grow is challenged in this paper.These researchers report that increased levels of carbon dioxide (when combined with the other effects of climate change) actually suppress growth rather than helping plants to flourish. The three-year field experiment was unusual in looking at the effects of temperature, rainfall and nitrogen deposits, as well as carbon dioxide, in an attempt to mimic future climate conditions as accurately as possible.

These guidelines, jointly developed by the Commission for Environmental Cooperation (CEC) and the International Council for the Exploration of the Sea (ICES), are intended to provide general guidance to scientists, planners and managers in their efforts to design, connect, manage, assess and adapt marine protected areas (MPAs) and MPA networks to be resilient to climate change at national and continental scales.
Hot spots of confusion: contested policies and competing carbon claims in the peatlands of Central Kalimantan, IndonesiaType:PublicationPublication date:Approach:
Central Kalimantan has been selected as the primary REDD+ pilot in Indonesia. In its peatlands expectations of payments for carbon emission reduction currently shape the discourse over natural resource management as a means of influencing policy and exercising power. Different types of actors use their own interpretation of history, facts, rules and norms to support their claims. Shifting national policies have over the past decades shaped the distribution of power and actual use of peatland. Actions to reduce emissions will need to appreciate the institutional complexity.

In Central America, one of the major changes in land use is the conversion of natural vegetation to crops (mainly to grazing lands). The practice of slash and burn agriculture has led to a decline in soil quality through nutrients depletion, organic matter reduction and soil erosion. Land degradation problems and desertification have increased with climate variability. Climate change represents an additional threat that could affect a country"s ability to meet urgent demands for rural development--food security included.
