USA. I see this in Oregon, Idaho, and Montana. Was just in Oregon, along the Columbia River gorge. Large streaks of dead trees through the lush forests.

A lot of this is Mountain Pine Beetle[1] though.

Which is exasperated by warming temperatures. Or to be precise, less bitter cold temps in the winter that control the beetle populations.

Very few organisms die from a 1-3 degree change in average temperature (some important ones, like coral, do). The majority of biological failures we will be seeing more of over the next 100 years will be due to issues with 1-2 week extremes - either heat waves, insufficient cold extremes, or large storms from excessive evaporation, etc. Then these failures with radiate throughout the food chain when the weakest link disappears.

So this mechanism of failure is not an outlier, but the normal face of climate change effects.

Yeah, lots of pines are brown in southern German woods, and even beech trees are affected (they have deeper roots). I haven't seen something like this.

Also this is not helped by spruce bark beetle outbreaks, which seem to be worse on warm years.
