Why are the seas rising, and why is this happening faster now?
These are the questions that Benoît Meyssignac will address on 18 November. He will then follow the extra energy trapped by the Earth, exploring where it goes and how it ends up raising the sea level. Finally, he will address the fundamental question behind it all. What is causing this imbalance: greenhouse gases, aerosols, or climate feedbacks?

Satellite data from the ESA Climate Change Initiative will help to answer this question. Join our webinar on 18 November: https://t.co/wwfkeXZ7AC

On Monday, Earth Information Day brought the climate observation community together at #COP31 in Antalya. 🌍
The European Space Agency was invited to explain how long-term, consistent satellite observations support climate science, decision-making and action.

[ESA Climate Office @esaclimate]

How much extra energy does our planet trap, and what happens to it? Few people have looked at this question as closely as Benoît Meyssignac.

A researcher at @CNES in Toulouse, he pioneered the use of satellite altimetry and space gravimetry to estimate the planet's energy imbalance. He contributed to the @IPCC_CH Special Report on the Ocean and Cryosphere in a Changing Climate, and he leads the Earth energy imbalance assessment of the @WCRP_climate's Global Energy and Water Exchanges Data and Analysis Panel.

Join us on 18 November at 4 pm CET to hear Benoît explain what this means for sea level. Register here: https://t.co/wwfkeXZ7AC

More information and tools to track the current El Niño event: https://t.co/u8uTxeBDUI

[ESA Climate Office @esaclimate]

🌍 El Niño is likely to strengthen into a very strong event in the coming months. Later today, a #COP31 side event will explore how global climate signals can be turned into timely, actionable information.

Watch @CAlbergel, Head of Actionable Climate Information Section at the European Space Agency, discuss how satellite observations help reveal effects on vegetation, fires and carbon exchange.

🕡 10 November, 6.30 - 8 p.m. UTC+3, Side Event Room 3, ZERZEVAN

Climate observations underpin early warnings, climate assessments, adaptation and informed decision-making. Yet global observing systems face funding uncertainty, infrastructure vulnerabilities, data continuity risks and persistent geographical gaps.

This afternoon, Susanne Mecklenburg of @ESA_EO will speak at #COP31 about sustaining observations and closing observation gaps.

🗓️ 10 November 2026, 2.30–3.30 p.m. UTC+3, UNFCCC Pavilion

🛰️ Can climate action be measured as well as it is promised?

During the European Space Agency's #COP31 side event today, speakers explore this question and discuss the current state of climate action. Contributions will cover how satellite observations help to tracking of GHG emissions and carbon sinks to assessment of climate adaptation progress, and their potential to support the 59 Global Goal on Adaptation indicators.

The programme brings together a variety of perspectives from scientists contributing to the Global Carbon Budget, greenhouse gas monitoring missions, climate adaptation and infrastructure resilience.

📅 9 Nov, 6.30 p.m. UTC+3, Side Event Room 9, Safranbolu

We look forward to an exciting event! https://t.co/jGemwbUlPG

Sea level is rising, and the pace is picking up. Can we explain sea level variabilty?

Join Benoît Meyssignac from the French space agency @CNES for our webinar on sea level budget closure on 18 November at 4 pm CET. He will demonstrate how satellite observations and climate data from ESA’s Climate Change Initiative can help us to identify the various factors contributing to global sea level change and to interpret long-term trends.

Sea level budget closure is the scientific verification that the total observed change in global mean sea level matches the sum of its individual physical causes and components.

The countdown to #COP31 is on.🌍 From 9–20 November, the European Space Agency takes part in the 31st United Nations Climate Change Conference in Antalya, Turkey. ESA demonstrates how satellite observations can help to track climate change, strengthen emissions reporting, and support adaptation planning, implementation monitoring and evaluation. 🛰️

ESA will contribute to discussions on:
• climate observations and the global records needed to sustain them
• satellite observations for greenhouse gas reporting and transparency
• measuring progress on climate adaptation
• understanding how El Niño can affect vegetation, wildfires and the land carbon sink.

How can satellite observations and climate models help us to understand the future of polar ice sheets?

In our ESA Climate Change Initiative webinar, Prof. Ruth Mottram demonstrated how the PISCO project uses these tools to study snow, melting and ice-atmosphere feedback processes across Greenland and Antarctica. These processes are key to improving projections of sea-level rise.

Missed our SATACI webinar with Marta Luffarelli? Here are three takeaways:

🛰 Co-location choices matter: aerosol–cloud relationships vary according to region, height, season, surface type, time lag, resolution and data product.
📊 Stratification and uncertainty propagation help to make satellite-based results more robust.
🌍 Initial results suggest that a satellite-based aerosol–cloud indicator could be used to track aerosol-related radiative effects at regional and global scales.

Snowfall, melting, glacier flow and iceberg calving all shape Antarctica’s ice sheet. Satellite observations and climate models help scientists understand how the balance between these processes could affect future sea-level rise.
