Honolulu, Baltimore, Charleston, S.C. and several other cities harmed by rising seas and extreme weather are suing the oil industry. At stake is who pays for the staggering costs of climate change.
Radiata pine was originally a solution to land erosion – but this Number-8 wire fix is past its due date and the forestry industry will likely wear the cost of change.
80% of carbon on land in stored in soil. Our new research investigated how erosion transports this carbon to the bottom of lakes, where it’ll never be released into the atmosphere.
