I love when there’s a new one from the doomsday cult
Earth’s ‘green center’ is drifting, and climate change is pushing it
Earth’s peak greenness has shifted decisively toward the northeast over the past four decades, establishing a measurable relocation of the planet’s living surface.
That steady drift redraws where seasonal plant growth concentrates, altering the geographic balance of carbon uptake and ecosystem timing worldwide.
Once you write “carbon” instead of “carbon dioxide” you’ve exposed yourself as this being not about science.
From daily satellite views of global vegetation, a single shifting point marks where the planet’s greenery concentrates most strongly at any moment.
Working from that planetary record, Professor Miguel Mahecha at Leipzig University documented how this balance point has moved persistently northeast over recent decades.
Rather than swinging evenly between hemispheres, the annual loop now leans north in every season and stretches farther east than before.
By compressing global plant activity into one moving coordinate, the finding sets up a clearer test of what forces are pushing Earth’s green center off its historical track.
OK, and? Things change during Holocene warm and cool periods. Do they have specific data on what happened during the previous warm periods over the last 8,000 years? If not, there is no comparison, and that is necessary for science.
Carbon dioxide explained about 70% of observed global greening, a long-term rise in leaf cover worldwide, in one large analysis.
Meaning this is all on you. Cult.
To see what might come next, the researchers ran the same metric through six major climate models.
Those Earth system models, computer simulations that couple land, air, and oceans, kept the northward drift under every scenario tested. (snip)
Satellites cannot see everything clearly, and clouds, snow, or dense evergreen can blur what greenness means on the ground.
To make the work checkable, the team released scripts that rebuild every figure and its codebase.
So, a ton of this is all based on garbage in garbage out computer models. I’m shocked!
Yes Teach they not only have specific data from the climate in the past they also have a unique designation for that study called PALEOCLIMATOLOGY
And that paleo data has shown that droughts in the Western US during the Middle Ages lasted for 100-200 years. Nothing new

William, William, William… whining, “your fault”… harrumphing, “Once you write “carbon” instead of “carbon dioxide” you’ve exposed yourself as this being not about science.”
Sweet merciful crap. Do you really feel misled by “carbon”?
How about “America won hockey gold”? Gold what??? America didn’t win, men and women playing hockey did.
Note, in the article William didn’t read, the scientists also discussed that increased global greening resulted from CO2, you know, plant food!

Are you now DENYING that CO2 stimulates green plant growth? We’ll wait for your answer…
Certainly we Norte Americanos recognize the seasonal changes of “green-ness”. Our deciduous trees are barren right now, but almost by magic as the days lengthen and warm, our tree factories convert carbon dioxide into gigatons of green leaves. In fact, this phenomeon spreads across the northern hemisphere like a wave. Alabama greens before Alaska!! Siberia later than the United States.
Said the PNAS article:
“Earth’s vegetation follows a rhythmic “green wave” that moves seasonally across the globe. It shapes the life cycles of organisms, biogeochemical cycles, and climate feedbacks, but until now, no intuitive metric existed to track its dynamics.
We present a method to track the wave’s center of mass. This “flight path” of the green wave’s centroid reveals a measurable directional drift of ecosystem functioning: The green wave is shifting, with faster changes during Southern Hemisphere summers and an overall northeastward movement. This approach expresses planetary change caused by land use and climate change in kilometers over decades and offers a basis to monitor biosphere dynamics and their interaction with Earth system dynamics and human activity.”
They didn’t mention global warming, did they?
Note the “It shapes the life cycles of organisms, biogeochemical cycles, and climate feedbacks…”
Recall that plants and animals coexist and are interdependent.
