According to the September 17 2004 issue of the journal Science, “A new, apparently improved, way to date the greatest mass extinction…fails to resolve geochronologists’ longrunning differences” (Kerr 2004: 1705).
The journal reported that “nailing down the time of the Permian-Triassic (P-T) extinction has revealed problems in the often competitive business of geochronology.
For comparison, our distant ancestors separated from apes only 7 million years ago.
Until recently the scale of the Permian Mass Extinction was seen as just too massive, its duration far too long, and dating too imprecise for a sensible comparison to be made with today’s climate change. In “High-precision timeline for Earth’s most severe extinction,” published in PNAS on February 10, authors Seth Burgess, Samuel Bowring, and Shu-zhong Shen employed new dating techniques on Permian-Triassic rocks in China, bringing unprecedented precision to our understanding of the event.
Rapid carbon belches, such as in the Permian and today, occur within the timeframe of fast feedbacks (surface ocean, water vapor, clouds, dust, biosphere, lapse rate, etc) but before the vast deep ocean reservoir and rock weathering can cut-in to buffer the changes.
Geochronology, the science of dating the age of our planet and its major events, is less precise than most people might believe.
Mostly these changes happened slowly enough that the long-term feedbacks of Earth’s climate system had time to process them.
This was true during the orbitally-induced glacial-interglacial cycles in the ice ages.
With that in mind, we were taken back eight months to a post on the subreddit r/Midessa where redditor KNEEGAN posed the following question: "What are some good creative things to do in Midland/Odessa for a first date?
Probably overthinking this, but are there any hidden gems?
