Fully agree. Here's a soil map of my island[0]. And the key to each type of soil.[1]
I really don't see an increase in average temperatures changing our podzols into a better soil.
But yes, if the climate change predictions pan out, then we can grow more grapes further south on the east side without fear of frosts, yay!
However, the climate change predictions also state that the eastern side of the island will experience far less rainfall, and mean far more frequent hot and strong winds[2] that a) strip soil moisture and b) blow away topsoil, while the west side of the island, which is already very wet, will see its annual rainfall increase significantly, and also experience far more frequent extreme flooding events which tend to be very bad for crops and animals, never mind the increased erosion or spoiling (via flood deposits) of land under cultivation. All thanks to the magic of orographic lift.[3]
Climate change predictions I'm referring to are here. [4]
All this due to a predicted increase in air movement from the west.
