☁️ Do changes in cloud altitude impact climate sensitivity?

A new study led by #MPI_scientist Lukas Kluft using an idealized radiative transfer model shows:
Positive radiative effects from unchanged high cloud temperatures cancel each other out with a reduction of the greenhouse effect of added CO₂.
📌 Therefore climate sensitivity stays nearly the same as without radiative effects of high cloud altitude – around 2.2°C per CO₂ doubling.
