The mysterious underwater avalanches reshaping Earth
24 January 2023
Turbidity currents are cascades of sediment that tumble down Earth’s 9000 submarine canyons carrying carbon, plastics and pharmaceuticals into the deep sea. We are finally learning just how often these dramatic events occur.
2022 Tonga eruption means we may hit 1.5°C of global warming earlier
12 January 2023
The massive eruption of a Tongan volcano in January 2022 has made it more likely that we will exceed 1.5°C of global warming within the next five years, but the effect will disappear by 2035
Climate cooling effect of volcanoes is bigger than we thought
10 January 2023
Analysis of sulphate particles in a Greenland ice core suggests we have underestimated the impact of volcanoes, and overestimated the contribution of anthropogenic sources
Venice may get a temporary respite from rising seas by 2035
6 December 2022
High winter sea levels in Venice are linked to warmer sea surface temperatures in the North Atlantic Ocean, and cooling in that ocean over coming decades should therefore temporarily compensate for the city's sea level rise
Landslides can be triggered by small changes in atmospheric pressure
16 November 2022
We knew earthquakes and heavy rain could initiate landslides, but now it seems alterations in atmospheric pressure can do it too if combined with certain conditions on the ground
Greenhouse gas emissions are warming up nights faster than days
29 July 2022
Since 1951, the gap between night and day temperatures has closed by 0.41°C, and simulations show that the bulk of this warming is due to greenhouse gas emissions
Circular cities experience more rain than square or triangular ones
11 May 2022
The shape of a city can influence the amount of rainfall it gets, because circular cities are better at mixing air fronts together
Survival of the friendliest? Why Homo sapiens outlived other humans
24 November 2021
We once shared the planet with at least seven other types of human. Ironically, our success may have been due to our deepest vulnerability: being dependent on others
Forget pristine habitats - for biodiversity save abandoned quarries
4 September 2019
The best way to save Earth’s threatened wildlife could be to protect its most unglamorous and geologically diverse landscapes, from scrubland to exhausted mines
