"Simultaneously mitigating near-term climate change and
improving human health and food security." Well, yes. What's new
for Science doesn't have to be new for klimazwiebel authors and
readers. But finally, good to hear that other people,too, seem
to give up their 2-degree goals and become more pragmatic and
realistic! Here the abstract: Tropospheric ozone and black
carbon (BC) contribute to both degraded air quality and global
warming. We considered ~400 emission control measures to reduce
these pollutants by using current technology and experience. We
identified 14 measures targeting methane and BC emissions that
reduce projected global mean warming ~0.5°C by 2050. This
strategy avoids 0.7 to 4.7 million annual premature deaths from
outdoor air pollution and increases annual crop yields by 30 to
135 million metric tons due to ozone reductions in 2030 and
beyond. Benefits of methane emissions reductions are valued at
$700 to $5000 per metric ton, which is well above typical
marginal abatement costs (less tha
