This year marks the 100th anniversary of Milutin Milankovitch’s first paper about Earth’s climate. Milankovitch argued that the amount of solar radiation Earth receives, and hence its climate, varies cyclically as its orbit changes due to gravitational tugs from the other planets. His climate theory fell into disrepute during the 1950’s but was rehabilitated in the 1970’s. Today, many peopl ...[Read More]

This image shows bottomset beds from the Kerinitis Gilbert-type delta. The Pleistocene delta uplifts along the active southern margin of the Corinth rift in Greece. A bottomset bed is one where layers of sedimentary material lying along the bottom of a body of water near the point of entry of a stream are subsequently covered by foreset and topset beds in the formation of a delta. Thus in this ima ...[Read More]

GeoPolicy: How geoscience can support the European Green Deal

Chloe Hill November 13, 2020

Earlier this year, the EGU hosted the Integrating science into the EU Green Deal event in collaboration with the Intergroup on Climate Change, Biodiversity and Sustainable Development to outline how the geosciences can most effectively support the European Green Deal and ensure its ambitious biodiversity and zero-pollution targets are reached. The event provided policymakers, scientists and indust ...[Read More]

This image shows benthic foraminifera species of Favulina hexagona (Williamson, 1848) together with nanofossils enclosed inside the shell hexagons. This modern foraminifera species was found in the sediment core retrieved from the western slope of the Rio Grande Rise (western South Atlantic). Description by Liubov Kuleshova, after the description on imaggeo.egu.eu. Imaggeo is the EGU ...[Read More]
