☆ Nowhere for the water to go: Dubai flooding shows the world is failing a big climate change drainage test
  + stars: | 2024-04-21 | by ( Michelle Castillo | ) www.cnbc.com   time to read: +2 min
The Dubai flooding last week illustrated how urban engineering is failing a major climate change test. The United Arab Emirates' city and others like it built on previously uninhabitable areas reflect 20th century urban development ideas that result in the blocking of natural water absorption systems. What's known is that Dubai was built on sand, a natural environment which lets water seep into the soil very easily. But by pouring massive amounts of concrete on top of Dubai's natural terrain, the developers effectively blocked the soil from absorbing water. Plastic products don't absorb water well, and when they end up in landfills around the world, massive piles of trash contribute to a global backup of natural drainage systems.

Heating systems are breaking down in Russia's harsh winter, leaving many people freezing. Much of Russia's Soviet-era infrastructure needs modernizing. AdvertisementHeating systems are breaking down in Russia's harsh winter, leaving many people freezing as Moscow continues to spend on its war in Ukraine. The brutal conditions are made worse because Russia's infrastructure is poorly maintained, with many of its facilitates dating from the Soviet era, according to media reports. About 40% of the communal heating grid in the country needs to be replaced urgently, she added.

☆ Concrete is a huge source of carbon emissions. These researchers are working to make it greener
  + stars: | 2023-06-16 | by ( Mark Tutton | ) edition.cnn.com   time to read: +7 min
With pressure on the construction industry to decarbonize, researchers around the world are looking for ways to make concrete greener. CarbonCure injects captured CO2 into concrete as it’s mixed, where it reacts with cement to increase the strength of the concrete. As well as sequestering CO2, the company says this extra strength means the concrete can be made with less cement. From salt water to cementIn the United Arab Emirates (UAE), researchers are working on a process to cut concrete’s carbon footprint while tackling another environmental problem. “The construction industry is one of the oldest industries and we might have some resistance to change the material that (it is) currently using.
