Those losses have come despite the sophistication of Israeli tanks and Israel's experience using them. AdvertisementThe recent images of an advanced Israeli Merkava tank blazing on the Gaza border evokes memories of another October war 50 years ago. Nonetheless, about 20 Israeli tanks have been knocked out over the past two months by Hamas, an irregular force that lacks advanced weaponry.

Hamas drones dive-bombing Israeli tanks is probably more of a rare occurrence than a decisive tactic — though the IDF has mounted steel cages on its tanks for protection.

☆ Underground climate change: How heat is trapped under the surface, threatening buildings

"There's already a significant amount of heat beneath our feet," Rotta Loria said. The research, published in July in the journal Nature, detailed how heat trapped under the surface is causing a phenomenon called "underground climate change" and could cause major cities including Chicago, New York and London to "sink." This underground climate change is different from the climate change in the atmosphere, which comes from greenhouse gasses caused by burning fossil fuels. As the heat spreads, the ground also deforms, which can cause city structures and infrastructure to crack. While researchers have worried about the potential of cities to sink due to heavy building loads, spreading heat like this can cause similar displacements.

☆ ‘Underground climate change’ is deforming the ground beneath buildings, study finds

CNN —A phenomenon that scientists have called “underground climate change” is deforming the ground beneath cities, a study conducted in Chicago has found. Technically known as “subsurface heat islands,” underground climate change is the warming of the ground under our feet, caused by heat released by buildings and subterranean transportation such as subway systems. “Deformations caused by underground climate change are relatively small in magnitude, but they continuously develop,” he said. “Calling it climate change seems like a bit of a coattail thing,” Archer, who was not involved with the study, said. The term “underground climate change,” however, was not coined for this study — it has been in use, and the phenomenon a subject of research, for some time.

Since the mid-20th century, the ground between the city surface and the bedrock has warmed by 5.6 degrees Fahrenheit on average, according to a new study out of Northwestern University. “All around you, you have heat sources,” said the study’s author, Alessandro F. Rotta Loria, walking with a backpack through Millennium Station, a commuter rail terminal underneath the city’s Loop district. “These are things that people don’t see, so it’s like they don’t exist.”It isn’t just Chicago. In big cities worldwide, humans’ burning of fossil fuels is raising the mercury at the surface. But heat is also pouring out of basements, parking garages, train tunnels, pipes, sewers and electrical cables and into the surrounding earth, a phenomenon that scientists have taken to calling “underground climate change.”
