*Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off.*

Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found.

The study combined paleoclimate records with computer simulations of atmosphere-ocean interactions and the team’s co-authored paper is accepted for publication in Geophysical Research Letters. (more…)

Seals, satellites, climate changes

It’s not the satellites but the Elephant Seals who are now providing data and info about how quickly the Antarctic Ice caps shrinks and grows (among many other clues). As Seals are natural habitants of the Antarctic marine ecosystem, so they are providing the most valuable and sophisticated data which are 30 times more than conventional sources.
