Unbelievable news yesterday: EDGE is one of two Earth System Explorer missions. Led by @helen-amanda.bsky.social (Scripps) ➡️ cryosphere & John Armston from @umdgeogr.bsky.social ➡️ vegetation.
I am proud to be part of EDGE.
Launch in 2030 at earliest: long wait for much needed data!

A new all-electric double-decker Climate Stripes bus has started taking passengers around Reading today.
The bus shows the warming stripes for Reading back to the 1860s and will hopefully help start climate conversations amongst passengers.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

Which option do we choose - act or delay?
These are the 'warning' stripes highlighting global choices. Do we act rapidly and keep global temperatures below 2°C, or delay and end up in a 3°C world (or worse)?

Great reflection of Emma, her outstanding contributions and her potential. Looking forward for those who are inspired by Emma's work and ethos to step up and build on her vision.
Devastating news that marine biologist, science communicator, and UniMelb VC Professor Emma Johnston has died after a short illness.
She really was an extraordinary and visionary leader, and I have no doubt she would have made a fine Chief Scientist one day.

Emma Johnston was a visionary scientist, environmentalist and leader, with an abiding hope for humanity
The University of Melbourne Vice-Chancellor, who has died aged 52, was driven by a deep love of science and a desire to safeguard the planet’s future.

#COP30 in extra day - Adaptation finance is nowhere near what vulnerable nations need. This is the red line for LDCs. We need strong LDC Fund replenishment & a commitment to triple adaptation finance by 2030. Immediate 1.5 °C action required.
