A three-day, in-person hackathon analyzing how the new generation of CMIP7 models represents historical trends and multidecadal variability, is organized by the CLIVAR CEMT-MV research foci, from 6 to 8 January 2027. The hackathon will be held at three hubs (Boulder, Taipei and Tokyo) over the same three days. It will consist of some lectures and tutorials on CMIP data analysis with the majority of the time spent hacking.
Participation is by application, and applications are due October 24th, 2026 and notification will be received in late October / early November. The hackathon is open to all career stages.

The WCRP Eath System Modelling and Observations (ESMO) Core Project is launching an open call for new panel members to join the Working Group on Numerical Experimentation (WGNE).
This is a great opportunity to join this group of experts and help advance numerical experimentation and the development, evaluation and improvement of Earth system models for weather, climate, water and environmental prediction across timescales. Current areas of interest include numerical methods, dynamics and physical parameterisations and their coupling; coupled Earth-system processes; systematic-error diagnostics; high-resolution and km-scale modelling; ensembles and uncertainty; AI/ML and hybrid models; model verification; and computational scalability. WGNE reports to the ESMO SSG as well as the Research Board of WMO, and has interactions with several ESMO, WCRP, and WMO bodies.
Applications can be made through this form. For more details, please take a look at the full call. Deadline for applications is 31 October, 2026.
2026’s extreme heat, wildfires and droughts are underscoring just how quickly our climate is changing. At the same time, climate science is advancing rapidly, with thousands of new studies published every year. The 10 New Insights in Climate Science report distills influential, emerging, and policy-relevant findings from the latest research into ten key insights for decision-makers ahead of the UN climate negotiations at COP. The webinar will include an overview of this year’s findings, expert perspectives on selected insights and an audience Q&A.
Join the International Science Council, Future Earth, the Earth League and the World Climate Research Programme for the launch of the 10 new insights in climate science 2026-27 report. The webinar will be held on 6 October 2026 from 13:00-14:00 UTC.
The World Climate Research Programme (WCRP) Regional Information for Society (RIfS) Core Project will convene two online fora for the climate research community, anchored by panel discussions on overshoot trajectories, consequences, mitigation, and adaptation challenges. Mark your calendar for:
- Webinar 1 – September 30, 12:30–14:00 UTC – Lived Experience: Trajectories and Consequences
- Webinar 2 – October 15, 07:30–09:00 UTC – Navigating the Return: Mitigation and Adaptation Challenges

It is with great sadness that we announce the passing of our friend and colleague Professor Krishna AchutaRao. Krishna was an active member of the WCRP Joint Scientific Community, a Lead Author of the IPCC and a highly regarded member of the Indian and international science community.
To quote a long-time colleague and friend of Krishna's, Prof. Roxy Koll
"Krishna was a long-time friend and colleague, and over the years we had many conversations and arguments about climate science. What brought me closer to him was his keen scientific temper, his extraordinary attention to detail, and above all, his sense of humour. He would question an argument until he was satisfied that it stood up scientifically, but our conversations would very often leave me smiling. He was also a clear and principled critic whenever scientific temper was compromised, something that has become increasingly important in the present political climate. That combination of scientific rigour, intellectual courage and humour is something I will always remember about him."
He was widely regarded as an excellent scientist and equally remembered as a nice person. There have been a number of articles in the Indian press outlining his many contributions:
- The Indian Express: https://indianexpress.com/article/india/krishna-achutarao-iit-delhi-climate-scientist-dies-62-10865578/
- Hindustan Times: https://www.hindustantimes.com/cities/others/renowned-scientist-prof-krishna-achutarao-passes-away-at-62-101788545205719.html
- Down To Earth: https://www.downtoearth.org.in/amp/story/climate-change/major-loss-to-indian-climate-science-scientific-community-civil-society-mourn-demise-of-krishna-achutarao
He will be sorely missed by many, including those in the WCRP community.
