Giant sequoia trees, the largest living organisms on the planet – some more than three millennia old – have started dying from beetle attacks linked to the climate emergency, the preliminary findings of a new study have revealed.
The deaths of the trees, some of which lived through the rise and fall of hundreds of empires, caliphates and kingdoms – not to mention the inauguration of every US president – have shocked researchers in their speed and novelty.
In
Sequoia and Kings Canyon national parks in the Sierra Nevada, California, 28 giant sequoias have died from a seemingly deadly interaction between bark beetles, drought and fire damage since 2014, according to a joint National Park Service and US Geological Survey study that will be published later this year.
