Over-reliance on land for carbon dioxide removal in net-zero climate pledges

Countries' current net-zero climate pledges require roughly 1 billion hectares (0.9–1.1 billion) of land for carbon dioxide removal, with over 40% of that area involving conversion of existing land uses to forests. The authors find that the scale and rate of land-use change implied by these pledges…

How long does full biodiversity recovery of a restored grassland take?
Our claim: Full biodiversity recovery can take decades — some grasslands need 75+ years for pollinators to return.
Source says: “Recovered grasslands need more than 75 years of continuous management to regain their biodiversity” — A Kobe University study found recovered grasslands need more than 75 years of continuous management to regain biodiversity, because specialized pollinators return slowly.
How long does a restored grassland take to recover fully?
Our claim: Full recovery takes decades — restored grasslands needed 75+ years of management to match ancient grassland plant diversity, and pollinators lag behind even that.
