Climate records stored in marine sediments reveal different ice sheet and ocean responses to falling atmospheric CO2 concentrations from the warm Pliocene to the ice ages of the Pleistocene.
The Tibetan Plateau is a major force in the global climate system and a hot spot for climate change. A new review summarizes the state of knowledge and identifies research needs related to the region.
Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.
AGU has various avenues for promoting noteworthy research published in our journals and books, which increases visibility, downloads, and citations.
Modeling air flow in wet porous media relies on quantifying the combined role of fluid and media properties and flow dynamics on the microscale displacement mechanisms and macroscale unstable flow.
To enhance flood modeling, it is imperative to gain a comprehensive understanding of the causative mechanisms and cutting-edge models and tools, while also acknowledging their uncertainties.
To reduce persistent aerosol-climate-forcing uncertainty, new in situ aerosol and cloud measurement programs are needed, plus much better integration of satellite and suborbital measurements with models.
Airborne dust not only causes disease, it also menaces transportation on land, sea, and air; disrupts renewable energy systems; transports pathogens and toxic substances; and poses many other hazards.
With heat waves expected to worsen in the 21st century it is essential to take stock of our current understanding, knowledge gaps, and to set research priorities.
From sediment cores to speleothems, environmental archives are helping us to understand the history of wildfires.
