Creating a Digital Twin of Earth to Tackle Climate Change

Scientists have developed a complex computer model to simulate Earth’s weather, climate, and human activities’ impact on the planet. The goal of this artificial intelligence (AI)-enabled “digital twin” is to offer dependable insights on extreme weather and climate change.

Named Destination Earth (DestinE), the computer model is a significant evolution from previous weather or climate forecasts that focused on either specific regions or global systems. DestinE integrates all these elements with human activities to create a comprehensive depiction of Earth’s varied processes. This project was initiated by the European Commission on June 10, with over €315 million funding from the Digital Europe program.

Margrethe Vestager, Executive Vice-President for a Europe Fit for the Digital Age, hailed the launch of the initial DestinE as a true game-changer in combating climate change. She noted that the model could help us anticipate future scenarios like never before.

Dual Focus of DestinE

The initial DestinE includes two models. One concentrates on climate change adaptation, and the other on weather extremes. Both draw from various data sources, such as the Copernicus program. The plan is to progressively enhance DestinE over the coming years, leading to a complete digital replica of Earth by 2030.

Why a Digital Twin of Earth is Needed

As extreme weather events become more frequent and severe due to climate change, it is vital to assess the impacts accurately. The World Meteorological Organization (WMO) reported over two million deaths from extreme weather-related events between 1970 and 2021.

DestinE is expected to aid Europe in responding effectively to natural disasters, adapting to climate change, and evaluating the potential socioeconomic and policy impacts of such occurrences. The model can offer hypothetical scenarios, such as deciding the best locations for wind farms or crop planting as the climate changes.

How DestinE Supports Europe’s Climate Goals

The European Commission has partnered with the European Centre for Medium-Range Weather Forecasts (ECMWF), the European Space Agency (ESA), and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) for DestinE. As part of its ambitious plan to be the first climate-neutral continent by 2050, the European Union is heavily investing in green technology. This project aligns with that goal, aiming to facilitate sustainable development and bolster environmental policies in future years.

The Role of Supercomputers in the Project

Creating a detailed model like DestinE requires substantial computing power. A 2021 study estimated that a supercomputer with 20,000 graphics processors would consume approximately 20MW of power for such a model. DestinE relies on Europe’s High-performance computers (EuroHPC), including the LUMI supercomputer in Kajaani, Finland, where almost half of its energy comes from renewable sources. By 2027, the team plans to have additional digital twins and services operational, with the goal of creating “a full digital twin of Earth” by 2030.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
