The Sustainable Development Goals map out a broad spectrum of objectives. Analytical tools in form of the Index and Dashboards provide a starting point to set national baselines, and allow comparison of the SDGs with other indices of well-being.

Hemispheric climate shifts driven by anthropogenic aerosol–cloud interactions

A southward shift of the tropical rainbelts over the late twentieth century has been attributed. Climate simulations suggest that the mechanism for this influence lies largely with the interaction of aerosols with clouds.

Biogeochemistry: Warmer Arctic weakens vegetation

Warm conditions in the Arctic Ocean have been linked to cold mid-latitude winters. Observations and simulations suggest that warm Arctic anomalies lead to a dip in CO2 uptake capacity in North American ecosystems and to low crop productivity.

Geomorphology: Origins of low-relief plateaus

Relatively flat, low-relief plateaus contrast with glacially carved, deep fjords. Computational experiments suggest that these astonishing landscapes are formed exclusively by glaciers.

Formation of plateau landscapes on glaciated continental margins

Low-relief plateaus separated by deeply incised fjords are hallmarks of glaciated, passive continental margins. Spectacular examples fringe the once ice-covered North Atlantic coasts of Greenland, Norway and Canada, but low-relief plateau landscapes also unde...

A reverse energy cascade for crustal magma transport

2017-07-10

Direct constraints on the ascent, storage and eruption of mantle melts come primarily from exhumed, long-frozen intrusions. These structures, relics of a dynamic magma transport network, encode how Earth’s crust grows and differentiates over time. Furthermore...

Reduced North American terrestrial primary productivity linked to anomalous Arctic warming

10.1038/ngeo2986

2017-07-10

Warming temperatures in the Northern Hemisphere have enhanced terrestrial productivity. Despite the warming trend, North America has experienced more frequent and more intense cold weather events during winters and springs. These events have been linked to an...

High levels of endocrine pollutants in US streams during low flow due to insufficient wastewater dilution

10.1038/ngeo2984

2017-07-10

Wastewater discharges from publicly owned treatment works are a significant source of endocrine disruptors and other contaminants to the aquatic environment in the US. Although remaining pollutants in wastewater pose environmental risks, treated wastewater is...
