Climate Service Center Germany (GERICS), Helmholtz-Zentrum Hereon

The Climate Service Center Germany (GERICS) was initiated by the German Federal Government in 2009 as a fundamental part of the German hightech-strategy for climate protection at Helmholtz-Zentrum Geesthacht – Zentrum für Material- und Küstenforschung GmbH (since March 31, 2021 renamed in Helmholtz-Zentrum hereon GmbH). In June 2014, the center – later renamed GERICS – became a scientific organizational entity of Hereon.

We are located in the historic “Chilehaus” in Hamburg and employ an interdisciplinary team of natural and social scientists. The total staff number is currently more than 70. The director of GERICS is meteorologist and climate scientist Prof. Dr. Daniela Jacob.

With the start of the fourth period of program-oriented funding of the Helmholtz Association (PoF IV) in January 2021, the Helmholtz-Zentrum Hereon has given itself a new scientific organisational structure. The center now comprises 15 institutes. It thus followed the recommendations of the scientific and strategic reviews of the Helmholtz Association over the past three years. At the same time, GERICS was given the status of a Hereon institute.

The area of coastal research in Hereon was also restructured and now comprises the three new institutes Institute of Coastal Ocean Dynamics; Institute of Coastal Systems – Analysis and Modeling; and Institute of Coastal Environmental Chemistry. With these three institutes and GERICS, Hereon is represented by four institutes in the Helmholtz Research Field Earth and Environment.

In the funding phase PoF IV, all centers of the Research Field Earth and Environment work in the joint program Changing Earth – Sustaining our Future. Within this program, GERICS is mainly working on the topic Coastal Transition Zones under Natural and Human Pressures (designated as Topic 4). In addition, GERICS is also involved in two other topics (Topic 1: The Atmosphere in Global Change and Topic 5: Landscapes of the Future).

Think tank for climate services

Global climate change has different regional impacts, which are already noticeable today. We will have to adapt to these different impacts, and this poses a challenge to a range of different policymakers.

For example, politicians, public administrations and businesses are faced with questions such as: to what extent will cities have to improve their rainwater management with regard to future heavy precipitation events? What does a climate-adapted urban development look like? How can companies take into account climate change impacts in the frame of their process planning? How do climate change impacts affect increasingly global supply chains? These questions reflect the range of different information that decision makers will need in relation to climate change impacts.

GERICS functions as a think tank for climate services in order to meet these information needs. GERICS develops prototype products in the area of climate services and works in close cooperation with science and practice partners from politics, economy and administration. GERICS actively promotes networking between these actors.

GERICS offers in scientifically sound manner products, advisory services and decision-relevant information in order to support government, administration and business in their efforts to adapt to climate change. The focus of our current activities is in the water, energy, ecosystems sector, and cities.

For activities connected with adaptation to climate change highly resolved climate change information is needed. In order to provide local climate change information, GERICS is involved in the development of different models and methods.


Issue Paper: Saving the Planet

Humans are destroying the planet through unrelenting emissions of greenhouse gases, land use change and pollution, causing widespread biodiversity loss and ongoing land, forest and ocean degradation that are undermining human health and harming agriculture and food production. These challenges can be addressed in a limited window of opportunity. G7 leaders at Elmau should:

  1. Create climate clubs
  2. End fossil fuel subsidies
  3. Expand climate finance
  4. Bolster biodiversity
  5. Strengthen sustainable agriculture, food and water security
  6. Create climate–health benefits

These six recommendations should be implemented in SDG-supportive, jobs-rich, inclusive, equality-enhancing, gender-equalizing,  independently monitored and continuously improved ways.
