2025 blev tredje varmaste året som uppmätts. Uppvärmningen har gått betydligt fortare än man trott för 10 år sedan. – Det är inte förvånande att temperaturen fortsätter att stiga så länge utsläppen fortsätter, säger klimatforskaren Frida Bender på @bolincentre.bsky.social www.tv4.se/artikel/1upG...

Pulitzer-winning writer @elizkolbert.bsky.social visited the Bolin Centre & @stockholm-uni.bsky.social to explore how Svante Arrhenius’s 19th-century ideas still shape our understanding of global warming and climate change. Read about her visit and upcoming project on our website. 👇

Lignin diversity helps plants thrive on land – without them, they become small, sterile plants that produce far less biomass. 🪴 This is revealed in a new study in @newphyt.bsky.social by @stockholm-uni.bsky.social @bolincentre.bsky.social @uspoficial.bsky.social & #TUAT 👇

Varmare och torrare somrar gör skogarna mer sårbara för granbarkborrar. En ny studie av bl a Caroline Greiser, Stockholms univ, visar att angreppen höjer temperaturen i drabbade områden. Men lövträd pekas ut som lösningen på uppvärmningseffekten. @bolincentre.bsky.social www.svt.se/nyheter/loka...

Dandelions that clone themselves still make pollen, but why? The #NoSexPoorPollen project led by @yannickwoudstra.bsky.social studies how pollen degrades when it’s no longer needed for sex, and what that means for evolution 🌼 Learn more about the project below!

New study out in @science.orgs Science Advances! 📣 The uplift of East Africa during the Miocene epoch dramatically transformed the region’s climate and ecosystems, promoting the expansion of grassland and reshaping habitats for mammals and early hominoids. 👇 @stockholm-uni.bsky.social @ethz.ch
