The clock is ticking for climate change mitigation. Geoengineering is gaining ground as an option, but it needs to be examined at a large scale to determine its effectiveness and associated risks.
Despite much emphasis on diversity in the US, geoscience remains one of the least diverse scientific disciplines. If we want to achieve and maintain diversity, we need to make our work environments welcoming to a broad spectrum of voices.
Communities around the Arctic are already seeing the effects of melting permafrost. Some of the biggest effects of this thaw will probably emerge in the coming centuries.
Forests are important for the global carbon cycle, and for mitigating greenhouse gas emissions. However, the role forests play in carbon sequestration should not eclipse everything else we value them for.
The ocean overturning circulation is potentially sensitive to climate change. In the north and south alike, human influence is less pronounced than we thought, but that is no reason to relax our watchfulness.
Billions of years ago, high atmospheric greenhouse gas concentrations were vital to life's tenuous foothold on Earth. Despite new constraints, the composition and evolution of Earth's early atmosphere remains hazy.
Investigations of sexual harassment are difficult and potentially destructive to all involved. It is imperative that they are carried out quickly, with high priority and acted upon decisively where misconduct is identified.
The review process is at the heart of scientific publishing. We would like to share with our readers some of the considerations that go into finding the best possible set of referees for each paper.
The Paris Agreement on climate change has shifted international focus to more stringent mitigation, and asked the scientific community to work out what that means on a tight timeline. The challenge is steep, but well worth a go.
Groundwater flow meddles with hydrological, environmental and geological processes. As water scarcity issues mount for people living above ground, the vast stores of freshwater in the subsurface require research attention.
