Hotspots of carbon confusion in Indonesia threaten to warm the world more quickly

Indonesia has promised to become a world leader in reducing greenhouse gas emissions. In 2009, the president committed to a 26% reduction in greenhouse gas emissions by 2020 to below 'business-as-usual' levels. Of this total, 14% would have to come from reducing emissions from deforestation or forest degradation. Investments by foreign governments and other bodies are expected to raise total emission reduction from 26% to 41%.
While international negotiations on rules about how to reduce emissions and slow global warming are slow but ongoing, the Indonesian and Norwegian governments signed a letter of intent under which up to US$ 1 billion is available to assist in setting up a 'stop deforestation and forest degradation' system that also addresses peatland emissions. Part of the agreement is that Indonesia will implement a moratorium or 'two-year suspension on all new concessions for conversion of peat and natural forest'.
Promising as this may sound, the devil is in the detail. A lot depends on how 'peat' and 'natural forest' are defined and how rights are agreed upon. Strong lobbies from the forest and tree-crop plantation industry argue that the economy will be harmed if 'business as usual' is interrupted. According to news sources, definitions of 'natural forest' and 'peat' differ between drafts prepared by the Indonesian Government's emissions reduction taskforce and by the Ministry of Forestry. There are several key issues that need to be resolved.

Turtle populations affected by climate, habitat loss and overexploitation

The sex of some species of turtles is determined by the temperature of the nest: warm nests produce females, cooler nests, males. And although turtles have been on the planet for about 220 million years, scientists now report that almost half of the turtle species is threatened. Turtle scientists are working to understand how global warming may affect turtle reproduction. To bring attention to this and other issues affecting turtles, researchers and other supporters have designated 2011 as the Year of the Turtle. Why should we be concerned about the loss of turtles?
"Turtles are centrally nested in the food web and are symbols of our natural heritage. They hold a significant role in many cultures. For example, in many southeast Asian cultures turtles are used for food, pets, and medicine," explains Deanna Olson, a research ecologist and co-chair of the Partners in Amphibian and Reptile Conservation steering committee spearheading the Year of the Turtle campaign.
