Tropical deforestation causes large reductions in observed precipitation - Nature A pan-tropical analysis using satellite, station-based and reanalysis datasets shows that deforestation causes reduced precipitation, and demonstrates that the effect increases with spatial scale.

Why cite such a study if your model findings oppose reality?

You just don't!

Shows the sea ice decline in the different scenarios "Observationally-constrained projections of an ice-free Arctic even under a low emission scenario"; https://www.nature.com/articles/s41467-023-38511-8

Slowly model results are closing in on an Arctic sea ice free September:

"The stronger SIA declines have advanced first ice-free years to around the 2030s–50s in all SSP scenarios."

Sadly, the spread is way too large as it could happen as early as 2027-2030...
