Earth system data sciences Prof. @UniLeipzig @RSC4Earth related to @UFZ_de @iDiv @SCADS.AI, worried about climate extremes, biodiversity, the human-environment nexus and the 🌎's future in general. Editor with https://www.earth-observation.net/
As described in the paper the projection to the lat-long surface leads to an error and is misleading ... (multiple vectors can have the same lat-long positions) ...that is why a x,y,z-version is needed.
More specifically, check out this element greenwave.earth/centroid.html (... especially before calling it chartjunk! ... how sad... is this really how we want to communicate amongst scientist?? 🙈)
And now also in French!
We needed to show the centre of mass of global vegetation greenness, which lies inside the sphere — that’s the blue trajectory you see. The transparency allows this ... if we chose a viewing angle that makes this visible. If you have a better solution, we’d genuinely love to hear it 🙂
Please read the paper or check out our interactive data viz where the concept is explained step by step: greenwave.earth
The transparency is functional! The quantity we estimate (the centre of global vegetation greenness in this case) lies inside the sphere, while the data are on the surface. We made the sphere transparent to show both the interior point and the surface pixels contributing to it @gdkrmr.bsky.social
And now in عربي Arabic! Thanks to Khalil Teber!

The greenness of the Earth’s terrestrial vegetation changes throughout the seasons. Researchers can calculate the global “green centre” and track its movement over several decades. They have observed a gradual shift towards the north-east. By Ida Flik. https://greenwave.earth/
🌍 The earth’s green is increasing and its centre is moving north-east. Vegetational shift to the north is even stronger in the southern summer – surprising new facet of #globalgreening 🌱 Published in PNAS

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.

The wave of green that sweeps Earth from the north in boreal summer to the south in austral summer is shifting due to climate change. Researchers found the centroid of the wave moving northward since 1982 and eastward since 2010. In PNAS: https://ow.ly/PjPU50YmYKz
This website and design is done my the amazing Ida Flik - half scientist, half data journalist: idaflik.github.io
and German 😜 ... and we had no time for more... but depending on the responses might consider it soon! What do you think? Helpful?
... Spanish ☺️ ...
Our team is highly international! When we came close to publishing our latest PNAs paper, we decided to use that diversity not only in the research — but also in the outreach. We built an interactive website explaining the results greenwave.earth in Chinese ...
With this I am referring to this study: www.pnas.org/doi/10.1073/...
Interesting media pattern: our new PNAS paper on the global green wave is mostly covered in languages linked to the authors (German, Spanish, Italian …), strongest response from DE. Why does the origin of a study matter so much for coverage when the science itself is global? bsky.app/profile/migu...
Unsere Studie von @chs42.bsky.social super für den @spiegel.de aufbereitet!
