Climate News Worth Celebrating: The Earth Is Getting Greener.

Global greening is not a new discovery. NASA satellite observations reported 10 years ago that up to half of Earth’s vegetated lands had experienced significant greening over the preceding 35 years, with rising atmospheric carbon dioxide (CO₂) identified as a major contributor.
In 2016, NASA reported that the increase in leaf area amounted to the equivalent of adding roughly two continental United States’ worth of greenery to the planet.
A decade later, the evidence continues. A 2026 paper in Nature Reviews Earth & Environment, “Vegetation greenness in 2025,” reports record global vegetation greenness, including particularly strong results in croplands. The study reports that 77.6 percent of cropland area experienced a positive greenness anomaly in 2025.
For a world continually told that it is teetering on the edge of ecological catastrophe, a record-green planet seems like something worth mentioning. Plants, apparently, missed the memo that carbon dioxide is supposed to be an environmental villain.
The biology here is elementary. CO₂ is an essential raw material of photosynthesis. Plants combine carbon dioxide, water, and energy from sunlight to manufacture the compounds they need to grow. Increase atmospheric CO₂ and, when other requirements such as water and nutrients are available, many plants respond with increased growth and improved water-use efficiency.
More importantly, this isn't merely a greenhouse experiment. Satellites have measured the effect on a planetary scale.
Other recent research attributed about 70 percent of observed global greening to CO₂ fertilization. Nitrogen deposition was attributed to another 9 percent.
