Going Down: How Do Cities Carry That Weight?
Calculations show that the added weight of growing cities can lead to tens of millimeters of subsidence, an effect that needs to be considered for coastal cities under threat by sea-level rise.

Deep Decarbonization? Yes We Can!
Modeling the U.S. energy system demonstrates several pathways to net-zero CO2 emissions by 2050. The pathway with the lowest cost, 0.2–1.2% of GDP, relies on >80% contribution of renewables.

High Climatic Response of High-Latitude Forests
The seasonal amplitude of atmospheric CO2 is increasing, partly due to boreal forest responses to warming. Photosynthesis and expansion of boreal forests are shown here to be temperature-limited.
