Researchers analyzed 40 years of satellite greenness data and tracked the center of mass of global vegetation. They found that the planet’s center of greenness has been shifting northward and eastward and that this movement has accelerated over the past decade. eos.org/articles/ear...

🌍 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 1/x
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 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: ow.ly/PjPU50YmYKz
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.

🌍 Climate extremes, such as compound heatwaves and droughts, are increasing in both frequency and intensity, yet predicting their impacts on terrestrial ecosystems remains a challenge. Machine learning holds promise, but traditional datasets often struggle to represent these rare events effectively.

Decreased cloud cover partially offsets the cooling effects of surface albedo change due to deforestation - Nature Communications
This study shows that deforestation locally reduces global low-level and tropical high-level clouds, with the resulting warming partially counteracting the cooling of increased surface albedo.

However, we argue that (1) the PB figure exaggerate via quadratic scaling of effect sizes, (2) colour gradations are highly non-linear, and (1)+(2) amplifies the perception of high-risk areas: egusphere.copernicus.org/preprints/20...
