These images from 15 December 2025 show Earth’s atmosphere in terms of temperature and humidity — data that will support more accurate weather forecasting, especially for nowcasting rapidly evolving storms.

For a brief time in 2021, the northernmost land in the world was considered to be the newly discovered island of Qeqertaq Avannarleq north of Greenland.

But it would soon be revealed that it was just an iceberg.

couple interesting maps of climate change vulnerability across Canada by Isabeaux Graham on our team

check out more here: schoolofcities.utoronto.ca/layers-of-cl...

#maps #gis #canada #climateChange
Multivariate map of Canada showing environmental vulnerabilities – biodiversity loss, water stress, soil degradation, and deforestation – alongside accumulated climate events from the past several years – including floods, wildfires, long-term sea level rise, and droughts. The map combines these eight impacts via small pie charts, that when combined represent the intensity of climate-change risks.

For the first time, #Copernicus Sentinel-2A has captured night‑time images of Earth, spotting gas flares in the Middle East, wildfires in India and even fishing boats in South Korea.

The results from these tests are being used to prepare for Sentinel‑2 Next Generation.

Poignant comment on what we lose from the demise of the letter - as sparked by the news that Denmark’s postal service will stop carrying letters from the end of the year www.ft.com/content/feca...
There are other reasons to rue the letter's slow demise - including the potential loss to historians, biographers and archives. Letters convey personality and motivations, offering a contemporary record of events without the distortions of hindsight or edited memoirs. The deceased in future may leave behind troves of electronic correspondence. Compared with today's popular Letters Live charity events, though, where actors read out remarkable letters of the past, it is hard to see future audiences being as enthralled by live readings of WhatsApp messages.
