Taiwan’s tallest tree found with help of citizen science

Deep in Taiwan’s misty mountains, researchers have confirmed the tallest tree in the country: a thousand-year-old fir tree higher than a 20-story building, which they’ve named β€œthe heaven sword of the Da’an River.” Climbers scaled the tree and dropped a measuring tape from the top to the forest floor during the Lunar New Year holiday in January 2023. The tree measured 84.1-meters (276-feet). The findings have been published in Frontiers in Forests and Global Change. A team of ecologists, geologists, remote-sensing specialists, professional climbers and Indigenous people that calls itself the β€œTaiwan tree seekers” began the search in 2014. β€œThe common characteristics [of the team] are probably that we are all tree lovers and like adventures,” Rebecca Chia-Chun Hsu, lead author from Division of Forest Ecology, Institute of Taiwan Forestry Research, told CNN. β€˜The Heaven Sword’, Taiwan’s tallest tree, measures 84.1 meters.

The island sits where the tropics meet the subtropics, and its mountains host several giant conifer species. The species behind the new record, Taiwania cryptomerioides, is known to the Indigenous Rukai people as β€œthe tree that hits the moon.” Although nearly 60% of Taiwan is covered in forest, loggers cleared much of the island’s old-growth forest between 1912 and 1991. However, its steep slopes were too dangerous to reach, and pockets of ancient forest survived. Still, finding the tallest tree amid the rugged terrain was a task.

Soaring solar and a surge in hydro push more coal off the US grid

Last year, the first few months of data from the US grid suggested that fears of a data-center-driven surge in demand were becoming a reality. Demand had risen by about 3 percent, triggering a surge in coal, interrupting what had been a long downward trend. But over the course of the year, both trends slowed considerably.

A year later, all of that seems to be in the past, as the US has returned to its normal pattern: slow growth, with renewables pushing coal off the grid. The one oddity is that hydroelectric production has surged without a corresponding increase in capacity, likely due to unusually warm weather in the western US causing the snowpack to melt early. That may have consequences later in the year.

Pushing fossil fuels out

Overall demand in the US grew by only 1.5 percent in the first quarter of 2026 compared to the same period the year before. Often, changes in demand during this part of the year are driven by weather-related heating demand. But the US had an unusual combination set of weather conditions to start 2026, with the western half baking in unseasonal warm temperatures, while the eastern half suffered a deep freeze. So we'll probably need data from more of the year before we read too much into the small rise in demand we've seen so far.
