Diatoms explain release of CO2

(Phys.org) —Scientists have found unexpectedly high concentrations of opal, a mineral containing silicate, in marine sediments during the transition periods from ice ages to warm phases. The explanation as to what caused ...

Early human migration to Americas linked to climate change

Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper published today in the Proceedings ...

Scientists probe Earth's core

We know more about distant galaxies than we do about the interior of our own planet. However, by observing distant earthquakes, researchers at the University of Calgary have revealed new clues about the top of the Earth's ...

New temperature reconstruction from Indo-Pacific warm pool

A new 2,000-year-long reconstruction of sea surface temperatures (SST) from the Indo-Pacific warm pool (IPWP) suggests that temperatures in the region may have been as warm during the Medieval Warm Period as they are today.

How fast can microbes break down oil washed onto Gulf beaches?
