The ToE (Time of Emergence) for temperature and sea ice is in the near future, i.e. somewhere before 2050, whereas the amount of rainfall will enter a new climate state at the end of the century

phys.orgRobust method predicts beginning of new climate in Arctic based on warming, wetting and sea ice lossWhen does "anomalous weather" become "a new climate"? The moment that variations in a specific climate variable turn into the new normal is termed Time of Emergence (ToE). Scientists from the University of Groningen and the Royal Netherlands Meteorological Institute (KNMI) have developed a method to predict the time of emergence in various Arctic regions, based on warming, wetting, and sea ice melting.

India must rethink its Arctic outlook

As conflict zones multiply globally, another frontier is quietly slipping into turmoil — the #Arctic. Long seen as a realm of scientific cooperation and environmental protection, the polar north is becoming a theatre of #military and #geopolitical competition. With #Russia more assertive, #China expanding its Arctic ambitions, and #Washington renewing interest in #Greenland, the region appears set for a renewed phase of strategic contestation.

To be sure, the #militarising impulse of Arctic powers is not new. Nor is the tendency to leverage polar presence for wider strategic manoeuvering. United States President Donald #Trump was the first to drop pretences when he proposed buying Greenland in 2019. Far from the absurdity many deemed it, the idea had clear geopolitical merit; behind Mr. Trump’s theatrics lay a deeper instinct — a recognition that the Arctic was no longer peripheral to global power play, but central to it.

For non-Arctic powers such as #India, the implications of a militarised Arctic are serious, prompting many to reassess their regional postures. Even so, #NewDelhi remains curiously insulated from the region’s shifting realities. Faced with complex challenges closer to home, India appears oddly impassive to the dangers taking shape in the high north.
