Regional climate changes over the last 2,000 years mapped for the first time

An international team of 78 researchers from 24 countries have joined forces to learn how temperature has changed in the past 1- 2,000 years at the continental scale. The results were recently published in the scientific journal Nature Geoscience and reveal both large regional similarities and differences in the evolution of Earth's climate. In particular, temperature developments in pre-industrial times seem to have differed between the northern and southern hemispheres.
