Sedimentary structures from evaporative coastal environments indicate carbonate saturation, offer insight in mid-Mesozoic ocean chemistry and potentially even earlier times.
Conserving native ecosystems helps sequester carbon and mitigate climate change, but new statistical modeling questions the permanence of California’s carbon-rich forests with climate change.
Excess of a single nutrient, such as nitrogen, may boost plant productivity, but the imbalance leads to less efficient water use as plants scramble for the nutrients they lack.
Human-made channelization significantly accelerates peat decomposition and drives ground-surface deformation in tropical wetlands.
A millennial-scale ocean simulation indicates that oxygen gains in the deep ocean may offset oxygen losses in the upper water layer under a protracted climate change scenario.
New research indicates that nutrient loads delivered to South American ecosystems by dust originating in Africa are far lower than suggested in previous studies.
A unique fossil lake bed in New Zealand has revealed insights into global climate under elevated levels of carbon dioxide but is now off-limits to scientists.
A new international collaboration found that dry inland waters—no matter where they were located—contributed significant global carbon dioxide emissions.
In the age of monitoring nuclear weapons testing, existing regional seismic networks may be a key to discovering small, undetected explosions around the world.
Soils both emit and take up different biogenic volatile organic compounds, altering the chemical composition of the atmosphere and influencing local, regional, and global climate.
