The study looked at Thaumarchaeota archaea, which are found throughout the world's oceans. These single-celled organisms have one membrane sac that encloses their bodies. This organism, used in the study, was collected from a tropical-water tank at the Seattle Aquarium.

TEX-86 proxy for past ocean temperature reconstructions challenged, possible 21°C error

From the UNIVERSITY OF WASHINGTON Lab experiments question popular measure of ancient ocean temperatures Understanding the planet’s history is crucial if we are to predict its future. While some records are preserved in ice cores or tree rings, other records of the climate’s ancient past are buried deep in the seafloor. An increasingly popular method…

Why we live on Earth and not Venus

From the University of British Columbia: Compared to its celestial neighbors Venus and Mars, Earth is a pretty habitable place. So how did we get so lucky? A new study sheds light on the improbable evolutionary path that enabled Earth to sustain life. The research, published this week in Nature Geoscience, suggests that Earth’s first…

The Beryllium cycle as it applies to weathering

A surprising finding: weathering of rocks doesn’t change with climate change

Constant weathering Surprisingly stable behavior despite glacial and interglacial periods From: GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre That weathering has to do with the weather is obvious in itself. All the more astonishing, therefore, are the research results of a group of scientists from the GFZ German Research Center for Geosciences in Potsdam and Stanford University,…
