Ancient sea ice core sheds light on modern climate change

A 170 m record of marine sediment cores extracted from Adélie Land in Antarctica by the Integrated Ocean Drilling Programme is yielding new insights into the complicated relationship between sea ice and climate change.

Hydrothermal vents may add ancient carbon to ocean waters

Earth's oceans play a pivotal role in the global carbon cycle. As seawater moves and mixes, it stores and transports huge amounts of carbon in the form of dissolved organic and inorganic carbon molecules. However, the various ...

Emissions cause delay in rainfall

Earth bears many signs of human influence, from warming that exceeds pre-industrial temperatures to a rising sea. Add to that list, now, the human influence on the timing of Earth's water cycle, revealed by a new study led ...

Carbon emissions from dams considerably underestimated so far

Among other things, dams serve as reservoirs for drinking water, agricultural irrigation, or the operation of hydropower plants. Until now, it had been assumed that dams act as net carbon stores. Researchers from the Helmholtz ...

Streams and rivers emit more carbon dioxide at night than day

Streams and rivers emit large amounts of carbon dioxide into the atmosphere, but a new study published in Nature Geoscience led by researchers at the universities in Umeå and Lausanne shows that the flux may be greater than ...

High greenhouse gas emissions from Siberian inland waters

Rivers and lakes at high latitudes are considered to be major sources for greenhouse gas emissions to the atmosphere, but these losses are poorly constrained. In a study published in Nature Communications, Umeå University ...
