Paleoclimatologists investigate the climate of the past. Not only does that help us understand Earth’s history, it also tells us something about our planet’s future.
The Helmholtz-Zentrum Berlin (HZB) has committed to achieving greenhouse gas neutrality by 2035. To find its main emission sources, it determined its greenhouse gas footprint and had it verified by an external organization. In our interview, Carina Hanke, climate and energy manager at HZB, tells about the project’s challenges and results.
Carbon dioxide is not the only greenhouse gas – nitrous oxide also has a particularly strong effect. Its concentration in the atmosphere has been increasing for decades. This increase is due to the use of nitrogen fertilizer in agriculture, among other causes.
As a candidate for EU membership, Ukraine has to initiate a series of reforms and develop a reconstruction plan in the midst of the Russian war of aggression. A German-Ukrainian-Polish project aims to help make Ukraine’s climate and energy policies fit for EU accession.
Carbon dioxide, also known as CO2, is a chemical compound of carbon and oxygen and is the most important and best-known greenhouse gas.
Our food system puts considerable strain on the environment. Food production is one of the most significant causes of anthropogenic greenhouse gas emissions, yet up to 40 percent of all foodstuffs ultimately land in the trash. A mindful diet can contribute to climate protection and promote our health.
In Germany, technologies for capturing carbon dioxide and storing it underground (CCS) have been investigated and tested in pilot projects. Christoph Hilgers and Frank Schilling from the Karlsruhe Institute of Technology (KIT) argue that the nation's legal framework must be changed in order to implement industrial-scale projects.
The summer of 2023 was the hottest on record worldwide. The Mediterranean was one of the areas affected, with dramatic consequences.
Surveys show that public opinion about technologies for capturing and storing CO2 in Germany remains divided. Respondents are concerned that the focus on CCS can weaken climate policy, and they have doubts about the process’s safety. Appropriate measures can help to overcome these concerns, according to Danny Otto of the Helmholtz Centre for Environmental Research – UFZ.
