Earth crosses seven of nine planetary boundaries, scientists warn
Original: and the models behind climate plans may be too optimistic Land carbon uptake has stalled Changing energy and food comes
Earth has now crossed seven of the nine planetary boundaries that define a safe operating space for humanity, researchers say. New reporting points to stalled land carbon uptake, meaning forests and soils may be absorbing less CO2 than assumed, and warns that the models underpinning many national climate plans may be too optimistic. Commenters stress that changing energy and food systems must come first.
Why now: New warnings that key climate models are too optimistic and land carbon uptake has stalled are renewing debate over climate policy.
