Yes, forest trees die of old age. But the warming climate is killing them faster
The warming climate is killing Australia’s forest trees at a faster rate. This offers a glimpse of what may lie ahead for forests globally.

Warming disrupts the spring synchrony of conifers, decoupling photosynthesis from wood growth. This indicates increased carbon uptake won't necessarily lead to more stored carbon, reducing forests' potential as a carbon sink. @natclimate.nature.com www.nature.com/articles/s41...
