Following our @cbc-conference.bsky.social and the keynote by @lewan.uk I just read the Anti-Autocracy Handbook he and his colleagues wrote: research-information.bris.ac.uk/en/publicati... I found it timely and useful and recommend having a look

We can actually measure the frequency of insect concentration in the air by radar. Fascinating stuff, now published by an interdisciplinary team at our institute and beyond: ieeexplore.ieee.org/document/115... @jquaas.bsky.social @idiv-research.bsky.social @vogelwarte.bsky.social
Histograms of maximum daily insect concentration at 150, 250, 500, and 750 m above ground derived from the three radars.

Four panels with blue bars primarily on the left of the x axis. Green and reddish bars to the left with the latter spreading also to the right of the x acxis. 150m above ground at top and 750m above ground at the bottom.

Global greenness in September. Shown is a globe depicting average global terrestrial greenness in September, visualized as “height over ground” and averaged over the period 2000–2023. Greenness is derived from satellite remote-sensing observations provided by NASA’s Moderate Resolution Imaging Spectroradiometer and illustrates the large-scale spatial distribution of vegetation activity across the terrestrial biosphere.
