Have a nice Ostara yall

"This Ostarâ, like the [Anglo-Saxon] Eástre, must in heathen religion have denoted a higher being, whose worship was so firmly rooted, that the Christian teachers tolerated the name, and applied it to one of their own grandest anniversaries.[8]"

400 ppm CO2? Add Other GHGs, and It’s Equivalent to 478 ppm
(2013 article)
"What is so significant about this 400-ppm reading?
This isn’t the first time that the reading of 400 parts per million (ppm) of atmospheric CO2 was obtained. It was recorded at a NOAA’s observatory station in Barrow, Alaska, in May 2012. But the recent 400-ppm reading at Mauna Loa, Hawaii got into the news because that station produced the famous “Keeling Curve,” which is the longest continuous record of CO2 in the world, going back to 1958.
‘400’ is just a round number. It’s more of a symbol than a true threshold of climate doom. The real issue is that CO2keeps going up and up at about 2.1 ppm a year. Even though there was a global recession in which emissions were lower in most fully-developed countries, China, and to lesser extent India and Indonesia, blew right through and continued to increase their emissions."
"According to the paleoclimatological ice core record, if our planet warms more than 2 C globally (4 C at the poles), we are in trouble. That’s about 6 meters or 20 feet of sea level rise. Most of the world’s valuable infrastructure and high populations are along the coasts. So, the damage and cost of sea level rise alone is potentially very high. Other risky phenomena we face are shifting rainfall patterns that may move the locations of arable farmland out of the US and into Canada. Mexico could grow drier and drier, and there’s concern in the Department of Defense about potential challenges to the security at the southern US border. Other similarly vulnerable areas around the world could face desperate large-scale migrations of people seeking to find places to grow food."

Peruvian puquios were a “hydraulic system constructed to retrieve water” Article, Comments
"The puquios were the most ambitious hydraulic project in the Nasca area and made water available for the whole year, not only for agriculture and irrigation but also for domestic needs,” says Lasaponara, who has written about her satellite studies in Ancient Nasca World: New Insights from Science and Archaeology, which is due to be published later this year.
The origin of the puquios has remained a mystery to researchers because it was not possible to use traditional carbon dating techniques on the tunnels. Nor did the Nasca leave any clues as to their origin. Like many other South American cultures they had no writing system.
Their existence tells us something remarkable about the people who lived in the Nasca region from before 1,000 BC to AD750. “The construction of the puquios involved the use of particularly specialised technology,” says Lasaponara. Not only did the builders of the puquios need a deep understanding of the geology of the area and annual variations in water availability, maintaining the canals was a technical challenge as they spread across tectonic faults.
"What makes them even more remarkable is that they still function today"
