Large potential of strengthening the land carbon sink in China through anthropogenic interventions

Researchers assessed the potential of two alternative methods in strengthening China's land carbon sink. Ozone control and litter removal showed significant gains in regional carbon sinks, with conservative forestation contributing up to 12 Pg C a^-1 by 2060. This can help limit temperature rise to below 2°C above preindustrial levels.

Getting autism right

A Rutgers study finds that many autistic adults are aware of their feelings and can label them in vivid detail. Participants reported difficulty with 'affective contact' between autistic and nonautistic individuals due to misinterpretation. New therapy strategies focus on improving mutual understanding and embracing autistic perspectives.
