Hansen: paleoclimate shows 2 degrees climate target leads to multiple meters of SLR

Comparing previous interglacial periods, like the Eemian, to the present geological epoch, the Holocene, shows slight average temperature rises are strongly magnified around the poles. Even under the 450 Scenario 21st century sea level rise could reach multiple meters. “Current … Continue reading →
