- 1Earth crosses seven of nine planetary boundaries, scientists warn●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.
- 2Scientists warn key planetary boundaries have been breached●'Planetary boundaries' necessary for flourishing of life have been breached
Scientists warn that several of the 'planetary boundaries' — thresholds for Earth systems such as climate, biodiversity and nutrient cycles that allow life to flourish — have been crossed, according to a Guardian environment report. The finding suggests human activity has pushed conditions beyond the safe operating space for humanity, prompting renewed debate about environmental limits and the pace of policy response.
