Mapping reveals targets for preserving tropical carbon stocks

A new high-resolution mapping strategy has revealed billions of tons of carbon in Peruvian forests that can be preserved as part of an effort to sequester carbon stocks in the fight against climate change. Tropical forests convert more carbon from the atmosphere into biomass than any other terrestrial ecosystem on Earth. However, when land is used for agriculture, as a wood source, or for mining, carbon is often released into the atmosphere where it contributes to climate change. Tropical deforestation and forest degradation account for about 10 percent of the world’s carbon emissions annually. more »

Concluding instalment of the IPCC Fifth Assessment Report: Climate change threatens irreversible and dangerous impacts, but options exist to limit its effects

Human influence on the climate system is clear and growing, with impacts observed on all continents. If left unchecked, climate change will increase the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. However, options are available to adapt to climate change and implementing stringent mitigations activities can ensure that the impacts of climate change remain within a manageable range, creating a brighter and more sustainable future. more »

Coral growth rate plummets in 30-year comparison

A team of researchers led by Ken Caldeira working on a Carnegie expedition in Australia’s Great Barrier Reef has documented that coral growth rates have plummeted 40 percent since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown. In a quest for historical context on the peril facing coral reefs, the team compared current measurements of the growth rate of a section of Australia’s Great Barrier Reef with similar measurements taken more than 30 years ago. Their work is published in Geochimica et Cosmochimica Acta. more »

Perú’s Carbon Quantified: Economic and Conservation Boon

Scientists unveiled the first high-resolution map of the carbon stocks stored on land throughout the entire country of Perú. The new and improved methodology used to make the map marks a sea change for future market-based carbon economies. The new carbon map also reveals Perú’s extremely high ecological diversity and it provides the critical input to studies of deforestation and forest degradation for conservation, land use, and enforcement purposes. The technique includes the determination of uncertainty of carbon stores throughout the country, which is essential for decision makers. The mapping project is a joint effort among the Carnegie Airborne Observatory (CAO), led by DGE’s Greg Asner, the Ministry of Environment of Perú, and Wake Forest University. more »
