Every year the Faculty of Science and Technology arranges the Celsius-Linnaeus honorary lectures in memory of Carl von Linné and Anders Celsius, both distinguish professors at Uppsala University. The appointed Celsius-Linnaeus lecturers are at today's forefront of research within their fields.

In January 2022, Uppsala University celebrates "300 years of weather statistics - from Celsius until today". The Celsius-Linnaeus lecturers will draw attention to this by inviting five prominent researchers, three Celsius lecturers and two Linnaeus lecturers.
