Peat-based climate reconstructions run into murky waters?

Peatlands are globally important ecosystems that serve as archives of past environmental change. Peatlands form over thousands of years from the accumulation of decaying plants and hold water, or in some cases purely rainwater. ...

Local factors important for water availability

An important issue that has grabbed the attention of scientists and policy makers alike is the amount of freshwater that will be available to populations across different climate settings, especially as rain belts reorganize ...

Reanalyses find rising humidity in the Arctic

(Phys.org) -- Direct, reliable observations of atmospheric conditions stretch as far back as the mid seventeenth century, with otherwise consistent records being punctuated by periodic updates in methods, practitioners, and ...

Streamflow changes following the 2010 Chile earthquake

Changes in streamflow and groundwater levels are known to occur following earthquakes. But the mechanisms for the changes in streamflow are not fully understood and vary from one location to another.

Prediction system to protect astronauts from solar storms

(Phys.org) -- With the impending solar maximum expected to bring heightened rates of flares and coronal mass ejections (CMEs), putting at risk an ever-increasing human presence in space, Oh et al. designed and assessed a ...

Eddies drive section of thermohaline circulation

(Phys.org) -- Giant currents that traverse the world’s oceans may not be as stable as previously thought after researchers found a branch of one of these global currents was powered and steered entirely by eddies, one ...

Novel equations improve image processing

A specific class of mathematical equations is helping to solve major challenges in the field, facilitating advanced modelling in a number of applications from climate change to desertification.
