Arctic Chill

The 2kW fibre laser remains stable across 100 degrees Celsius temperature swings, offering portable defence capabilities without conventional heating or cooling systems

Denmark on Monday takes over the Arctic Council's rotating chairmanship from Norway at a time when Arctic security tensions are fraught and US President Donald Trump is seeking to annex Greenland. Denmark chose to name Vivian Motzfeldt, Greenland's foreign affairs minister, to be the new chair of the council, the eight-nation grouping of countries that border the Arctic. Denmark has rebuffed Trump's talk of buying the strategic Arctic island, a semi-autonomous territory of the kingdom. During Norway's two-year turn at the helm of the Arctic Council, the intergovernmental body was beset by strain over how to deal with Trump and Russia's war in Ukraine. Russia is the biggest Arctic nation and was the chair of the council before Norway. It was one of the few settings where Western countries and Russia worked together closely, but the other seven countries decided to pause their work with Russia in the council shortly after Moscow launched the full-scale invasion of Ukraine in February

The Arctic of today looks stunningly different from the Arctic of even one to two decades ago

A subpolar plankton species found in the Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, indicating that summers in the Arctic were ice-free during this period. Published in Nature Geoscience, this research analysed the microfossil content of sediment cores to determine the extent of sea ice present during the Last Interglacial, a recent period of the Earth's geological history characterised by a climate warmer than today. The Arctic sea ice, an important component of the Earth system, is disappearing fast due to climate warming, whereas the summer sea ice is anticipated to vanish entirely within this century. To gain a deeper understanding of the climate dynamics in a world without the Arctic sea ice, researchers have turned to analogues from our geological past. However, the extent of sea ice during this period has been intensely debated and there is no consensus, limiting understanding of this period and the ability of researchers to simulate it i
