A new study shows Earth’s first continents, known as cratons, emerged from the ocean between 3.3 and 3.2 billion years ago. Previous estimates suggested that large-scale craton emergence took place roughly 2.5 billion years ago.

Although volcanologists are getting pretty good at forecasting the start of an eruption, predicting the end is much more difficult.

The ESA and NASA have released the first globally harmonized assessment of above ground biomass. The Multi-Mission Algorithm and Analysis Platform (MAAP) provides seamless access to above ground biomass information from both ESA and NASA Earth observation data.

After a successful trial run in May, a NASA campaign is deploying aircraft, a research vessel and several kinds of autonomous ocean robots to study small ocean whirlpools, eddies and currents.

Environmental engineers at Duke University have demonstrated that sharp contrasts in relatively small land features play a substantial role in local weather developments, which can in turn influence larger climate trends.

Landsat-9 is a continuation of a series of Earth-observing spacecraft that started almost 50 years ago. No other remote-sensing system has kept a longer, continuos record of the changing condition of our planet.
