On Mars and Venus air is CO two, While on the Earth it is but a trace gas. Our rocks and water scrub the gas into The stable carbonates, which won’t degas. In torrid climates, weathering is fast. Cold rivers transport unreacted grains Fluvial temperature in eons past Can be deduced with XRF and brains. The elements in sediments explain An early Permian heats up and thaws. Jokulhlaups
6:43 AM | No Endangered Listing for Dusky Sharks (and That’s a Good Thing)
Though the fisheries news cycle has mostly been taken up by the 15-year anniversary of the Sea Around Us project (and some choice words between researchers), today also marked the official announcement of the 12-month finding on the petition to list dusky sharks on the U.S. Endangered Species Act.  Long story short, the National Marine […]

From flood basalt hot sulfur will exhale, Across the dying planet, smog bank draped The genie left the bottle, empty grail, No evidence what long ago escaped. The lava flows forget what they degassed A fleeting daydream, lost with time’s progress But though a hundred million years have passed The clinopyroxene preserves the S. Partitioning experiments defined! A synchrotron or ion probe

Our early atmosphere was quite anoxic ‘till early algae terraformed the Earth. One grand event, replacing gasses toxic? Or did O oscillate since life’s first birth? Did evolution make fate manifest? Inexorable progress of the gene? Or was the early oxygen repressed? Methanogenic dominance was seen. These visions of our past yearn to be fact. Hypotheses distinct yet plausible. The dawn

4:02 AM | Ocean Things to Be Thankful For: Megalodon is Dead, but We Still Have Sharks (and Whales)
This time of year, it’s appropriate to think of things to be thankful for.  This being an ocean-focused blog, I’d like to share something ocean-related that I’m thankful for, and hopefully spread a little Ocean Optimism in the process.  What I’m thankful for is that Carcharocles megalodon is extinct.  This may not seem like cause […]

The cratered lunar face preserves the song Of bolide roller derbies eons past But while the cold dead moon remembers long The rains of Earth reshape the surface fast. Did impacts peak four billion years ago? Or taper off through geologic time? Archean rocks are analysed to know micaceous balls were hot glass in their prime. This impact melt was blasted into space By comets larger than the dino's

12:12 PM | The wrong kind of Bang
In science education and popularization, there is a delicate balance that must be struck between overcomplicating and oversimplifying. Insufficient simplification can result in overly obtuse deviation into secondary details, which confuse and distract the readers and derail the flow of the prose.  Excess simplification can be wrong.  And this is where the Medium article by Ethan Siegel of “

The Permian extinction was severe, though only callous geos call it "great." Sulfur and carbon choked the atmosphere Siberian eruption exhalate. A lava-coal explosion, it’s surmised Spread fly ash all around the sickly Earth, But if this ash is made by wildfire, The evidence for coal fly ash is dearth. A sulfate drought could set the world aflame, The brimstone vapors choking off the
