When it comes to the impact of climate change on ecosystems, we still have large knowledge gaps. Most experiments are unrealistic because they do not correspond to projected climate scenarios for a specific region. As a result, we lack reliable data on what ecosystems might look like in the future, as a team of biodiversity researchers from Central Germany show in the journal „Global Change Biology“. The team reviewed all experimental studies on the topic. The researchers are now calling for the introduction of common protocols for future experiments.
