Report from the USDA showing NJ has lost a colder plant hardiness zone and gained a warmer hardiness zone more associated with Virginia. NJ may have to adapt plant life to the new hardiness zones in order to keep a healthy though changed ecosystem #CMPCS26

We're seeing droughts over the Indo-pacific and much heavier rainfall over the relatively arid near Peru and Chile and a powerful hurricane off the coast of western Mexico. Predicting a strong El Niño this year.

🚨🚨Emergency protest🚨🚨 The Drexel board will be at the constitution center in Old City (525 Arch St, Philadelphia, PA 19106) from 5-6. We're asking Drexel to disaffiliate from the Academy of Nat Sci to allow them to negotiate what's best for them w/o Drexel interference. Be there.

William Penn Foundation offers funding to keep Academy of Natural Sciences museum open
A Drexel spokesperson did not say whether the school had declined the offer, but said, “No proposal has been presented that would provide a permanent, sustainable path forward" for the museum.

Genuinely hard to believe Cohen is a media trained spokesperson. My guy says the Academy is like a 3 legged stool and they can save the education, and research legs, but not the museum. Hey Dave, what happens when you stand up a 2 legged stool by the way?

Several employees stopped and sat with me sharing their stories, their hopes and plans for the future, their worries, and how they were blindsided by @drexeluniversity.bsky.social announcing the closure with 30 days notice. And it's a travesty to close such a historic institution

I spent the last day of the Academy of Natural Science being open sitting and drawing. During this time Thousands of patrons passed me, many stopping to watch and ask me about my drawing. Some sharing their favorite stories of their past visits, and regrets of not visiting more frequently.
A drawing in charcoal of the Academy of Natural Science's extinct birds diorama. Featuring a Great Hulk, a Male and Female Labrador Duck, and an Eskimo Curlew.A placard at the Academy of Natural Sciences in Philadelphia. It reads "Something in Common

These birds may look very different from each other, but they have much in common. They are all water birds, they all used to live in extreme northern climates, and sadly, they are all extinct 

The great auk became extinct in 1852, the Labrador duck in 1878, and the Eskimo curlew in 1963. The remains of the last-known Eskimo curlew are stored here in the academy's  ornithology collection"

Four panel comic. Panel 1: a grey alien emerges from its UFO in front of a crowd of people standing below. The alien says, “earthlings… surrender now… we are—“ Panel 2: the first alien is interrupted by a second, different species of squid-like alien emerging from its ship. The second alien says, “humans! Prepare for—“ Panel 3: the two aliens quickly notice each other, looking surprised. Panel 4: the two aliens are laughing hysterically with their arms around each other amicably, each pointing to the other in a joking manner. This is the third time this has happened. A small group of onlooking humans stand behind them uncomfortably.

If you're wondering why all the aquariums and non-profits are posting "happy Shark Week" facts this week when Shark Week shows starts next week, it's because the Discovery Channel randomly changed when Shark Week shows start, squandering goodwill from partnering with aquariums and non-profits.
