Ulfani and her family have been living in the flooded family home as long as she can remember. Outside the house, the yard where she used to play with her friends is now filled with water about 8 inches high. The home’s concrete terrace is occupied by swimming guppies. Inside the home a snake slides out of the flooded kitchen, into the sea.

Rene Elter, a French archaeologist leading the dig, said researchers have studied over 100 of the graves.“All of these tombs have almost already been excavated and have revealed a huge amount of information about the cultural material and also about the state of health of the population and the pathologies from which this population may have suffered,” said Elter, the head of archaeology for ”Intiqal,” a program managed by the French nonprofit Première Urgence Internationale.

Elter pointed to the sarcophagi made of lead — one featuring ornate grape leaves, the other with images of dolphins — as exceptional finds.“The discovery of lead sarcophagi here is a first for Gaza,” he said.Given the rarity of the lead tombs, Palestinian archaeologists like Fadel Al-Otul suspect that social elites are buried there. Al-Otul said the cemetery probably used to be located in a city — Romans used to place cemeteries near city centers.

Alongside the sarcophagi, Elter’s team is restoring unearthed skeletons and piecing together shards of clay jars.The skeletons discovered at the site will be sent out of Gaza for additional analysis, according to Al-Otul. The remains are set to return to the Hamas-led Ministry of Antiquities and Tourism.

Elter said the territory needs a dedicated team to oversee archaeological activity in Gaza.

“The Gazans deserve to tell their stories,” he said. “Gaza boasts a plethora of potential archaeological sites, but monitoring each one, given the rapid pace of development, is no small feat.”took it one step further and calculated that changes in carbon dioxide may affect the climate.

and even home kitchencan show this with two plastic soda bottles, some carbon dioxide, air, a strong light bulb or flame and a thermometer. Heat up a bottle with regular air and one filled with carbon dioxide in similar ways, take their temperatures and after a while the carbon dioxide filled one should warm noticeably more.

That’s because of the geometry, spin and vibration of carbon molecules block the specific infrared wavelength of light that’s trying to escape Earth, Mann said. It’s a different wavelength than the light heading into the sun.Greenhouse gases, especially carbon dioxide, “correspond to sort of holes” in the light spectrum that would otherwise allow heat to escape, but they block the exits, Mann said.
