Climate change rate to turn southern Spain to desert by 2100, report warns

From the Guardian - Mediterranean ecosystems will change to a state unprecedented in the past 10,000 years unless temperature rises are held to within 1.5C, say scientists

"Southern Spain will be reduced to desert by the end of the century if the current rate of greenhouse gas emissions continue unchecked, researchers have warned.

Anything less than extremely ambitious and politically unlikely carbon emissions cuts will see ecosystems in the Mediterranean change to a state unprecedented in the past 10 millennia, they said.

The study, published in the journal Science, modelled what would happen to vegetation in the Mediterranean basin under four different paths of future carbon emissions, from a business-as-usual scenario at the worst end to keeping temperature rises below the Paris climate deal target of 1.5C at the other.

Temperatures would rise nearly 5C globally under the worst case scenario by 2100, causing deserts to expand northwards across southern Spain and Sicily, and Mediterranean vegetation to replace deciduous forests.

Even if emissions are held to the level of pledges put forward ahead of the Paris deal, southern Europe would experience a “substantial” expansion of deserts. The level of change would be beyond anything the region’s ecosystems had experienced during the holocene, the geological epoch that started more than 10,000 years ago."
