Forest carbon

WASHINGTON — Global warming could cause up to 60 percent of the world's permafrost to thaw by 2200 and release huge amounts of carbon into the atmosphere that would further speed up climate change, a study warned.

Austrian authorities have refused to publish the serial numbers of nearly 500,000 carbon allowances stolen from its registry in last month's cyber attack, in a move that has prompted fresh criticism of the European Commission's handling of the fraud.

The US-based conservation consultancy Wildlife Works Carbon won the race to issue the world’s first offset credits for the voluntary carbon market from a project designed to reduce emissions from deforestation and forest degradation (REDD).
