Turtles breeding earlier, but half as often, due to climate change
Climate change affects the turtles through many pathways, with warming altering breeding times, and marine food webs reducing reproduction

Can crushed silicate rock help cool the planet?
A new study suggests that enhanced rock weathering could remove up to 1.1 Gt CO₂/year by 2100 if it scales as past technologies have.
Climate solutions aren’t just chemical: they’re social.
