- 1Greenland and Antarctica Lost 12 Trillion Tons of Ice in 50 Years●Satellite Images Reveal Greenland and Antarctica Have Lost More Than 12 Trillion Tons of Ice Over the Past 50 Years
New satellite imagery shows Greenland and Antarctica have together lost more than 12 trillion tons of ice over the past half-century, according to a report by Smithsonian Magazine. The findings underline the accelerating pace of polar ice melt and its implications for global sea levels, with scientists warning that continued losses could have serious consequences for coastal communities worldwide.
- 2Polar vortex returns: what it means for winter●The polar vortex is returning. What's its role for winter?
Coverage is focusing on the return of the polar vortex, the band of cold air circling the Arctic, and its influence on the coming winter. When the vortex weakens or shifts, frigid air can spill into Europe and North America, driving cold snaps and storms. Meteorologists are weighing how its behavior could shape seasonal forecasts.
- 3Mobile apps turn Arctic community observations into climate data▼How mobile apps are turning Arctic community observations into climate data
Arctic residents are using mobile apps to record local observations such as ice conditions, weather and wildlife, which researchers convert into usable climate data. The approach combines Indigenous and local knowledge with digital tools, helping scientists fill gaps in a vast, sparsely monitored region where instrumental coverage is thin and change is happening fast.
- 4Environmental surveys completed in East Greenland before drilling decision▼Environmental surveys are complete in East Greenland before any drilling decision.
Environmental surveys in East Greenland have been completed, marking a key step before any decision on oil or gas drilling in the region. The findings are expected to inform authorities weighing whether to approve exploration off Greenland's east coast. The announcement is likely to draw attention from both energy firms and environmental groups concerned about Arctic drilling.
