However, although COVID-19 has contributed to a global reduction in carbon emissions (relative to 2019), it is clear that there is still much work to do when it comes to making the sorts of emissions …

These resolutions are not perfect — there is certainly much more that I could do to lower my footprint. However, I have …

A New Year’s Day Rock: Travertine Icings and Scums
Happy New Year! To celebrate the new year, here are some photos of some very new rocks. These travertines in Oman are some of the youngest rocks I’ve encountered in my geological wanderings. These “icings” and “scums” are travertines (mostly the mineral calcite) that are precipitating from highly alkaline (pH ~11-12) springs that form when rainwater circulates through mantle peridotite. Thin layers of newly-formed travertine (icings) often float on the …
