A better estimate of water-level rise in the Ganges delta

For the first time, scientists have provided reliable regional estimates of land subsidence and water-level rise in the Ganges-Brahmaputra-Meghna delta. Depending on the region of the delta, water-level rise could reach 85 to 140 cm by 2100. The work, published in PNAS on 6 January 2020 by...

Submarine cables: billions of potential seismic sensors!

Scientists have for the first time shown that it is possible to detect the propagation of seismic waves on the seafloor using submarine telecommunications cables. According to their observations, this existing infrastructure could be used to detect earthquakes, as well as swell and underwater noise...

Combating climate change: a worthwhile investment

Investing to limit global warming to 1.5 °C between now and 2050 would cost four to five times less than repairing the harm that a 2 °C temperature increase would cause to people, ecosystems and infrastructures. This statistic comes from an international study to which IRD and CNRS researchers have...

Observed controls on resilience of groundwater to climate variability in sub-Saharan Africa

Groundwater – a vital source of water for drinking and irrigation across sub-Saharan Africa – is, to a certain extent, resilient to climate variability and change, according to a new study co-led by IRD with University College London and Cardiff University. The research published on August 7, 2019...
