Engineer Dr Shaun Fitzgerald reports from COP29 on his discussions about climate repair as a looming necessity.

Stratospheric clouds over the Arctic may explain the differences seen between the polar warming calculated by climate models and actual recordings, according to researchers from the University of Cambridge and UNSW Sydney.

As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published today in Nature Geoscience.

The Centre for Climate Repair at Cambridge and Refreeze the Arctic Foundation (RAF) signed a multi-year agreement to fund research methods for brightening clouds to combat climate change.

Researchers have found that the movement of glaciers in Greenland is more complex than previously thought, with deformation in regions of warmer ice containing small amounts of water accounting for motion that had often been assumed to be caused by sliding where the ice meets the bedrock beneath.

The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.

Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for the speed at which the world’s second-largest ice sheet flows to the ocean.

The largest-ever study of tree rings from Norilsk in the Russian Arctic has shown that the direct and indirect effects of industrial pollution in the region and beyond are far worse than previously thought.

Is the North Pole still important, when most of us will never visit it and know almost nothing about it? A new book by University of Cambridge researcher Dr Michael Bravo charts the history of the North Pole and finds a place that is both real and imaginary, with fascinating stories to tell.

New DNA analysis reveals that, before their mysterious disappearance, the Norse colonies of Greenland had a “near monopoly” on Europe’s walrus ivory supply. An overreliance on this trade may have contributed to Norse Greenland’s collapse when the medieval market declined.
