My plane stopped in Panama in the middle of the night when i flew back from Uruguay in 1960. i started getting off the plane to look around, but it was still so hot I got right back to the plane!

Trancas are thundereggs from Mexico. as they formed in calcite magma, unlike other t-eggs they opened at the very center, so don't have the middle ball core as normal.
Usual Thunderegg: Starting spheroid: Mexican Trancas:

You need to use Cloudinary. I hate going to another site! Nice ring.

We need to start desalination of sea water.

www.accuweather.com/en/climate/where-sinking-cities-are-pushing-sea-level-rise-into-overdrive/1629311 Why are coastal cities sinking? According to a report in the Journal Nature, cities in the Northeast and along the Gulf coast are especially at risk for devastating flooding due to rising waters. Groundwater extraction is one of the primary drivers of coastal subsidence. Cities and industries are pumping water from underground aquifers faster than it can be replenished, a situation exacerbated by climate change-fueled drought. Excessive pumping lowers the water table and causes the overlying land to sink. The same thing happens when oil and gas are extracted from underground. On and offshore, the Gulf Coast is dotted with oil and gas facilities, which not only contribute to the climate crisis that is exacerbating sea level rise but are also one of the leading causes of land subsidence in the region. Other causes include seismic activity and soil compaction, either naturally from the weight of accumulating sediments over time or from heavy buildings pressing down on the ground, causing land to steadily sink. This is a particular problem in areas where new coastal land has been created over the years by backfilling with sediment. Cities on the East Coast where sinking land is exacerbating sea level rise include New York City and Atlantic City; Virginia Beach; Charleston, South Carolina; and Savannah, Georgia. New York City was hit with flooding during Tropical Storm Ophelia as shown here in late September, 2023. (Bing Guan/Reuters via CNN Newsource)
