The impact of Initialized Land Temperature and Snowpack on Sub-Seasonal to Seasonal Prediction (LS4P) Phase II focuses on the Rocky Mountain LST/SUBT effect on S2S prediction and the interaction between Tibetan Plateau Index (TPI) and Rocky Mountain Index (RMI).
This project (LS4P-II) intends to address two questions:
- Where are the hot spot regions of the surface temperature anomaly in the western US, mainly in the Rocky Mountain region, in the S2S prediction? How do the RMI and TPI synergistically affect global S2S predictability
- What is the relative role and uncertainties in the LST/SUBT processes versus in SST in S2S prediction? How do they synergistically affect global S2S predictability?

The 3rd GEWEX/LS4P-II International Workshop” will take place at the Hyatt Regency New Orleans at Room Strand 12AB on Sunday 14 December 2025 from 9:00 – 17:00 CST.

Measuring and understanding Eart Energy Imbalance (EEI), its time variability, and long-term trend is essential to understanding the current state of our planet and predicting its future evolution. Under its Data and Analysis Panel (GDAP), the World Climate Research Programme’s (WCRP) core project Global Energy and Water Exchanges (GEWEX) initiated the “Earth Energy Imbalance assessment”. The GEWEX-EEI assessment’s objective is to evaluate the quality and the uncertainty of current EEI estimates. It focuses mainly on two sources of data: 1) observations of the TOA radiative fluxes from space radiometry and 2) observations of the ocean heat content from in situ data, satellite altimetry, space gravimetry and ocean reanalysis.
The approach adopted in the GEWEX-EEI assessment is to design an intercomparison of EEI estimates and associated uncertainty. This intercomparison enables progress on:
- Assessing the quality of different EEI records
- Understanding the sources of uncertainty in different EEI estimates
- Understanding the causes for the spread in EEI estimates
- Quantifying and understanding EEI time variability including trends
- Improving regional earth energy and heat uptake estimates
Main Goals for this workshop:
- Assess closure of Earth’s energy budget from the top of the atmosphere to the bottom of the ocean.
- Advance our understanding of the causes of ocean heat content and energy balance variations.
- Explain the spread across EEI estimates; derive and recommend methods that reduce and quantify EEI uncertainty.
- Identify gaps, challenges and opportunities for the EEI observing system of the future.
EEI assessment Workshop Themes include:
Theme 1: Science of Earth’s Energy Imbalance
Theme 2: Advances in global and regional estimation of ocean heat content
Theme 3: Earth radiation at the TOA, surface and in the atmosphere
Theme 4: Earth’s heat inventory – deep ocean, land, atmosphere and cryosphere
Theme 5: Energy and Water Cycle Linkages and their impact on EEI
Theme 6: Future Ocean, ERB & EEI Observing Systems

The 6th Baltic Earth conference 2026 is hosted by the International Baltic Earth Secretariat at IOW and IOPAN, and will take place from 13 – 17 April 2026 at the Seetelhotel Villa Esplanade mit Aurora and Seetelhotel Pommerscher Hof, located in Heringsdorf on the Usedom Island, Germany.
The Baltic Earth scientific network strives to achieve an improved Earth System understanding of the Baltic Sea region as the basis for science-based management in the face of climatic, environmental and human impact in the region. Baltic Earth brings together a broad international research community around scientific issues relevant for societal efforts to achieve sustainability in the region. Baltic Earth targets the atmosphere, land and marine environment of the Baltic Sea, its drainage basin and nearby areas with relevance for the Baltic Sea region. Baltic Earth has entered a new phase, called Baltic Earth 2.0. It is characterized by a new secretariat shared between Germany and Poland and revised research topics, which will be the foci of the conference.
The conference sessions reflect the research themes of the new Baltic Earth 2.0 science plan. The topics listed below are preliminary and indicate the scope of the conference.
- Climate variability and teleconnections
- Small-scale (submesoscale) processes and their impacts
- Natural hazards and their impacts
- Sea level and coastal change
- Biogeochemistry of the Baltic Sea – Linking observations and modelling
- Multiple drivers of Earth system changes
- Marginal Seas – Humans and Environment
- Future projections of the Baltic Sea region
- Philosophical aspects related to Baltic Sea Earth system research

Annual meeting of the International Network for Alpine Research Catchment Hydrology (INARCH) is by invitation only.
INARCH has completed Phase I Science Plan and have a suite of well-instrumented research basins, high-resolution forcing meteorological datasets, and advanced snowdrift-permitting and glacier-resolving hydrological models that are exemplars of Integrated High Mountain Observation and Prediction Systems (IHMOPS). The IHMOPS was used to improve our scientific understanding, and evaluate observed changes, data and models around the world. The models are being used to estimate the sensitivity of the high mountain cryosphere and hydrology to climate change.
Moving forward to phase II, includes the following issues and priorities:
- Improve mountain hydrometeorological and related observations, understanding and predictions to help adapt to rapid climate change.
- Implement recommendations from the WMO High Mountain Summit—integrated observation and prediction systems. How can we build up integrated prediction systems around these research basins and apply them to the larger earth systems that derive from mountains, and what does it take to do that?
- Science for society. Can we contribute to the development of ‘fit-for-purpose’ hydrological, meteorological and climate information services in high mountain catchments?
- Mountain systems include human-water interactions and complex ecological interactions – how can we address this in our models? Can we use these to develop solutions to help achieve water sustainability in high mountain river basins and downstream?

The Trans-Himalayas, home to all summits exceeding 8,000 meters in elevation, is highly sensitive to climate change due to its extensive ice, snow, permafrost, and carbon reserves. The cryospheric meltdown caused by global climate change affects over 2 billion people downstream. However, environmental research in this region faces significant uncertainties in quantifying climate change and its cross-sectoral impacts. This highlights the urgent need for a comprehensive Earth system approach.
Climate change is a global issue that affects livelihoods across borders. To collectively address the challenges it poses to regional sustainability and global Earth science advancement, the International Association for Trans-Himalaya Earth System Science (ATH) is pleased to announce the 1st International conference on Trans-Himalaya Earth System Sciences, to be held in Kathmandu, Nepal in October, 2025.
The conference will focus on a range of key themes of:
- Glacier Melt and Earth System Consequences
- Biodiversity Conservation and Global Change
- Tectonic Uplift of the Trans-Himalayas and its Impacts
- Trans-Himalayas Teleconnections
- Hazards Risks and Adaption Strategies
- Other related topics
Forecasts on sub-seasonal to inter-decadal timescales have a diverse range of applications in climate services, including disaster preparedness, and short- mid- and long-term planning. However, the complexity of methods, uncertainty assessment and ways to merge forecasts across timescales presents a significant knowledge and skill gap. The Summer School on Climate Prediction Across Timescales aims to address these gaps, and it is, designed for early-career researchers and advanced students interested in the science and application of climate predictions. The school will offer foundational and advanced lectures in the mornings and interactive, hands-on lab sessions in the afternoons.
