🌍 New today in Nature: Climate models need faster, more frequent data updates - here's how to do it 🌍

Today, a group of scientists, led by Vaishali Naik published a Comment in Nature calling for a major shift in how we support climate modelling.

🌊 The Atlantic “conveyor belt” (AMOC) is weakening under climate change. A new @nature.com study suggests collapse is unlikely this century, but the risks remain very serious.

Hear from lead author @jonbakerocean.bsky.social in our next webinar.

Atlantic overturning inferred from air-sea heat fluxes indicates no decline since the 1960s - Nature Communications The AMOC is crucial for the global ocean overturning circulation and controls the climate around the North Atlantic. Here, the authors use 24 Earth System Models from the CMIP6 to demonstrate tha...

Has the Atlantic Meridional Overturning Circulation (AMOC) weakened over the last decades? In our new study, we combine state-of-the-art CMIP6 models and observation-based estimates of the air-sea heat flux in the North Atlantic to show that the AMOC has not declined since the 1960s! 🌊

An evolving Coupled Model Intercomparison Project phase 7 (CMIP7) and Fast Track in support of future climate assessment Abstract. The vision for the Coupled Model Intercomparison Project (CMIP) is to coordinate community based efforts to answer key and timely climate science questions and facilitate delivery of relevant multi-model simulations through shared infrastructure for the benefit of the physical understanding, vulnerability, impacts and adaptations analysis, national and international climate assessments, and society at large. From its origins as a punctuated phasing of climate model intercomparison and evaluation, CMIP is now evolving through coordinated and federated planning into a more continuous climate modelling programme. The activity is supported by the design of experimental protocols, an infrastructure that supports data publication and access, and the phased delivery or “fast track” of climate information for national and international climate assessments informing decision making. Key to these CMIP7 efforts are: an expansion of the Diagnostic, Evaluation and Characterization of Klima (DECK) to include historical, effective radiative forcing, and focus on CO2-emissions-driven experiments; sustained support for community MIPs; periodic updating of historical forcings and diagnostics requests; and a collection of experiments drawn from community MIPs to support research towards the 7th Intergovernmental Panel on Climate Change Assessment Reporting cycle, or “AR7 Fast Track”, and climate services goals across prediction and projection, characterization, attribution and process understanding.

📣 CMIP7 Description Paper now available for comment on GMD 📣

Including climate science questions #CMIP7 will help to address, including model characterisation, process understanding, impacts and adaptations analysis, climate assessments; and more!

Comment now 👉 zurl.co/cmip7-paper

We tried to make #CMIP7 an inclusive, taking into account modeling centers and community needs. The design, I hope, reflects that -targeted on a tight timeline with flexibility to support a wide range of ESM science. So pls read, comment and start thinking about cool ways you can use this ensemble.
