🔥 New fire paper out - Fire regime changes in Canada: an update. Overall, the big-picture trends remain consistent: annual area burned, the annual number and size of large fires are still increasing, but the total number of fires for all sizes continue to decline.

Fire regime changes in Canada: an update

Given the recent rise in extreme fires, we present an update to a previous Canadian wildfire trend analysis (1959-2015) with nine additional years of data (2016-2024), an improved area burned dataset,...

Streaks of #highlatitudedust emitted in southern #Iceland.

This example illustrates an important fact about using polar sensors to detect pollution (dust in this case) and sensor spatial resolution.

Image of the week: Saharan dust sweeping west over the Atlantic towards the Canary Islands, captured by Meteosat-12 from 36,000km above Earth.
While dust can affect air quality & flights, it also fertilises the ocean, fuelling blooms of phytoplankton that support marine life. More at: bit.ly/4pL6ItX
