Radiolarians are significant contributors to the oceanic primary productivity and the global silica cycle in the last 500 Myr. Their diversity throughout the Phanerozoic shows periodic fluctuations.

Passing Stars As An Important Driver of Paleoclimate And The Solar System’s Orbital Evolution
Reconstructions of the paleoclimate indicate that ancient climatic fluctuations on Earth are often correlated with variations in its orbital elements.
What Turned Earth Into A Giant Snowball 700 Million Years Ago?
Australian geologists have used plate tectonic modelling to determine what most likely caused an extreme ice-age climate in Earth’s history, more than 700 million years ago.
Latitudinal Variation of Clouds’ Structure Responsible for Venus’ Cold Collar
Global Climate Models (GCM) are very useful tools to study theoretically the general dynamics and specific phenomena in planetary atmospheres.
Geoscientists Map Changes In Earth’s Atmospheric CO2 Over The Past 66 Million Years
Today atmospheric carbon dioxide is at its highest level in at least several million years thanks to widespread combustion of fossil fuels by humans over the past couple centuries.
Our Warming Planet Is Evolving Stronger Hurricanes/Typhoons/Cyclones
For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category […]
Ice World Exploration: Pilotless Uncrewed Aerial Vehicle Arrives In Antarctica
A team have arrived at Rothera Research Station, ready to start testing the new Windracers ULTRA autonomous drone in Antarctica. If successful, the new drone platform could represent a major […]
Exploring The Undiscovered Potential Of Deep Sea Microbial Ecosystems And Establishing Sustainable Thresholds For Their Preservation
We’re publishing this article today in advance of a COP28 talk entitled “Ocean biodiscovery, capacity development and equitable access to ocean biodiversity data” that Emma Bolton, Ocean Research Lead at […]
Planetary Survey From Orbit: Earth’s Surface Minerals In Arid Regions
Editor’s note: We’re now able to detect planets orbiting other stars. We can determine the size and basic composition of these worlds but only in a general sense. As newer […]
Using Genomics To Trace Ice Planet History: Octopus DNA Reveals West Antarctic Ice Sheet Collapse During Last Interglacial
Genetic analyses of an Antarctic octopus show that the West Antarctic Ice Sheet (WAIS) collapsed during the Last Interglacial ~129,000 to 116,000 years ago when temperatures were only about 1 […]
