This meeting is a ‘call to action’ to form an alliance to improve warnings of the proximity of catastrophic climate tipping points and to accelerate positive tipping points to avert the climate crisis. Speakers will be from academia, industry, government, and Third Sectors.  

Co-convened by Johan Rockström, Director of the Potsdam Institute for Climate Impact Research and Tim Lenton, Director of Global Systems Institute, additional Chairs include Justin Rowlatt, Gaia Vince, and Oliver Morton. 

Speakers confirmed include Speakers include W. Brian Arthur, Santa Fe Institute, Patricia Pinho, Amazon Environmental Research Institute (IPAM) and Keywan Riahi, International Institute for Applied Systems Analysis (IIASA). 

Over three days participants will go on a journey from facing up to the risks from climate change tipping points to being empowered by the opportunities in triggering positive social tipping points. 

Please have a look at the latest programme for further information on the speakers, workshops and plenaries.

We are pleased to announce the release of the Modern-Era Retrospective analysis for Research and Applications – 2 (MERRA-2) Stratospheric Composition Reanalysis of Aura Microwave Limb Sounder (M2-SCREAM) developed at NASA’s Global Modeling and Assimilation Office in collaboration with the Microwave Limb Sounder (MLS) team.

This stratosphere-focused chemical reanalysis provides assimilated global three-dimensional fields of ozone, water vapor, hydrogen chloride (HCl), nitric acid (HNO3), and nitrous oxide (N2O) mixing ratios, all of which are of primary importance to stratospheric chemistry and transport studies. M2-SCREAM assimilates MLS profile observations of these five species, alongside total ozone data from the Ozone Monitoring Instrument, with the recently developed Constituent Data Assimilation System (CoDAS). The system configuration includes a stratospheric chemistry module, StratChem and a version of the GEOS global circulation model with the dynamics constrained by meteorological fields from MERRA-2. The assimilated output is provided at a 50-km horizontal resolution on 72 model layers and at a three-hourly frequency. Analysis uncertainties are provided in a separate monthly data collection. A description and validation manuscript has been submitted to Earth System Science Data.

The current release covers the period from October 2004 to December 2021. Periodic updates are planned for the remainder of the MLS mission.

The M2-SCREAM data are available to the public through the Goddard Earth Sciences Data and Information Services Center (GES DISC) and can be accessed here.

A longer release statement can be found here.

Join us for a unique meeting that will:

• Improve warnings of the imminent risks of catastrophic climate tipping points.
• Accelerate positive tipping points to avert the climate crisis.

Work with world-leading experts to consider the latest science on climate tipping points and breaching planetary boundaries. Then explore the opportunities in triggering positive social tipping points. Interactive plenaries and action orientated workshops will create new networks of partners and resources for implementation after the conference.

Confirmed speakers include Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, Tim Lenton, Director of Global Systems Institute, Kate Raworth, co-founder of Doughnut Economics Action Labs and Laura Pereira, University of the Witwatersrand.

Please have a look at the latest programme for further information on the speakers, workshops and plenaries. Participants will join a growing alliance of partners collaborating to develop the urgent solutions required to address the climate and ecological emergencies through a socially just transformation.
