How big is the energy efficiency resource?
Environmental Research Letters, 2018 Most economic theorists assume that energy efficiency—the biggest global provider of energy services—is a limited and dwindling resource whose price- and policy-driven adoption will inevitably deplete its potential and raise its cost.

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages
American Journal of Botany, EarlyView.Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.
