China’s Great Green Wall Grows Fast, Yet Long-Term Carbon Storage Remains Unclear

New research using satellite data finds China’s Great Green Wall—the forest belt along the Gobi and Taklamikan deserts—lets planted trees accumulate leaf area 66% faster than natural forests, with about a 4.6% edge when age- and condition-matched; the advantage peaks around 30–40 years old and then fades. While planted forests gain carbon quickly and the project has expanded regional forest cover and reduced dust, natural forests remain superior for long-term carbon storage, raising questions about the wall’s climate benefits despite local air and dust-reduction gains.

China's Great Green Wall Grows Fast, But Its Climate Promise Is Complex

China’s 66‑billion‑tree Great Green Wall across the Gobi and Taklamakan deserts has expanded forest cover and reduced dust, but a Geophysical Research Letters study finds planted forests grow canopy 66% faster than natural forests and about 4.6% faster when age‑matched, with the biggest gains around 30–40 years before tapering. While planted forests offer strong short‑term carbon uptake, natural forests provide longer‑term storage and resilience, raising questions about the wall’s long‑term climate impact and how these artificial forests should be accounted for in carbon models.

JWST finds mysterious molecule, China's Great Green Wall outpaces forests, Medici murder mystery solved

Space headlines dominate this week: the James Webb Space Telescope detects a mysterious, unknown molecule in Pluto and Titan’s atmospheres, and Hubble spots unusual light from a distant galaxy. On Earth, China’s Great Green Wall has 66 billion trees growing faster than natural forests, for reasons researchers are still exploring. Archaeology sees a breakthrough as ancient-DNA analysis reveals malaria killed two Medici brothers, solving a 500-year-old murder mystery. The roundup also touches on related science news, from solar-storm protection ideas and CERN’s Large Hadron Collider upgrades to other advances in science and health.

China’s Great Green Wall: planted forests outpace natural forests in leaf growth

A satellite-based study finds that the 66‑billion-tree Great Green Wall in China is growing its canopy 66% faster than natural forests, likely because planted forests are younger, actively managed for rapid growth, and benefit from CO2 fertilization; while planted forests provide a strong short‑term boost to carbon uptake, natural forests tend to store more carbon long-term, underscoring the need to tailor reforestation—considering species, age and management—for climate benefits.

Africa's Great Green Wall: A grand dream unraveling in the desert

An in-depth look at Africa's Great Green Wall shows a multi-country, multi-billion-dollar effort intended to halt desertification, but years of funding and planning have yielded minimal ecological benefits: by 2020 only about 4% of land was restored and by 2023 just 13% of pledged funds had been disbursed, with problems like poor planning, weak local participation, and fragmented financing limiting impact, though a few oases and farms offer temporary gains and some donors remain cautiously hopeful.
