Leaf Wax Hydrogen Isotopes Reflect Storm Track Position Over Western North America We analyze modern leaf waxes in near-shore marine sediments spanning a north–south transect along the coast of western North America Leaf wax hydrogen isotope values become more negative at the l...

We have a new paper out in Paleoceanography and Paleoclimatology showing that the latitudinal gradient in leaf wax hydrogen isotopes over western North America reflects the mean climatological position of the storm tracks. agupubs.onlinelibrary.wiley.com/doi/pdf/10.1...

Deep ocean control of global temperature after net-zero emissions - Nature Geoscience When atmospheric carbon dioxide levels decline, increased ocean heat absorption would initially slow surface warming before warming the deep ocean, which ultimately raises global mean surface temperat...

🌊 What happens to global temperature after net-zero?

New results suggest deep-ocean processes matter: as vertical heat diffusion warms the deep ocean, reduced heat uptake could reverse surface cooling on 100 yr timescales.

…the climate system has a very long memory.

Paper Alert❗️We present the first Oligocene record of orbital variability in abyssal ocean temperature based on benthic foraminiferal clumped isotopes. Temperature changes up to 4 degrees C with a 110 kyr pacing, indicating Antarctic ice-volume at this time was less dynamic than previously thought.

Oligocene deep ocean oxygen isotope variations primarily driven by temperature - Nature Geoscience Large benthic oxygen isotope fluctuations in the Oligocene Southern Ocean primarily represent deep water temperature changes, suggesting the Antarctic ice sheet volume was relatively stable, according to a clumped isotope record.

For the first time, scientist discovered that the large up-and-downs in oxygen isotopes of the mid Oligocene were primarily driven by large temperature changes in the abyssal ocean and not, as previously assumed, to enormous changes in ice volume in Antarctica. 3/3

Wow!! Where is the sample from?

Exploring macroevolutionary links in multi-species planktonic foraminiferal Mg∕Ca and δ18O from 15 Ma to recent Abstract. The ratio of the trace element Mg over Ca (Mg/Ca) and the oxygen isotopic composition (δ18O) of foraminiferal calcite are widely employed for reconstructing past ocean temperatures, although...
