Ingenious pipeline could be a much-needed lifeline for dying coral reefs

Coral Bleaching in New Caledonia Global Coral Bleaching
Recently, the U.S. lost half of its Caribbean coral reefs in one year due to climate change. Data later confirmed that the thermal stress on the coral system was greater than the previous 20 years combined. These so-called “bleaching events” occur when corals are stressed by changes in the environment and expel their symbiotic algae. The exodus of algae causes the reef to turn completely white, thus the term bleaching. Professor emeritus at the University of Arizona, Mo Ehsani, believes using a system to deliver cool water directly to colonies at risk could reverse this dire trend.

Ehsani has been testing fiber-reinforced polymer (FRP) products for nearly three decades and founded, QuakeWrap, a construction company specializing in FRP commodities, in 1994. To prevent bleaching, Ehsani plans to pump cooler water to at risk coral through a lightweight FRP pipe. Unlike traditional rigid concrete or steel, FRP pipes are more cost effective and much easier to construct and install.

“It’s almost like a hose,” Ehsani explained to Popular Science. “It’s not subjected to any major loads or stresses. We can drop it right into the ocean, and it can handle the stresses.”

These cooling system will theoretically be powered by renewable, clean energy created on site by floating wave energy converters for an added dose of sustainability. Ehsani is currently trying to attract interest from the Australian government for a preliminary pilot program in the Great Barrier Reef. This would be a seemingly logical next step for both parties considering the world’s largest coral reef system has seen its fair share of massive bleaching events in recent years.

From 3D-printing coral models to more advanced aerial reef mapping, there is a host of clever tactics being considered to help minimize the effects of climate changes on our coral colonies. Currently, increased ocean temperatures are the predominant cause of coral bleaching, according to National Oceanic and Atmospheric Administration (NOAA). Once affected by bleaching, a healthy coral reef can recover — albeit more susceptible to future bleaching events — so long as surrounding oceanic temperatures return to their normal range. Seeing as 2016 was the hottest year on record for the third consecutive year in a row, these sturdy coral systems may need more than their innate stalwartness to withstand a perpetually warming planet.

Might be time to buy EVs, laptops, and smartphones ahead of Trump tariffs
evs laptops smartphones price hike tariffs download 4

Besides the traditional holiday shopping season, there might be good reasons to preempt some planned purchases between now and January 20: Price hikes are widely expected to be passed onto U.S. consumers should the incoming Trump administration carry out its plans to impose across-the-board tariffs on imports.

President-elect Donald Trump has said the U.S. will slap a new 25% tariff on imports from Mexico and Canada, along with an additional 10% on Chinese imports. While campaigning, Trump also mentioned a 10% tariff on all imports and an additional 60% tariff on imports from China.

Range Rover’s electric SUV gets tested in extreme heat

A big part of the reason it’s taken so long for Range Rover to develop its first-ever electric SUV is that the automaker wants the next-gen EV to remain, first and foremost, true to its roots.

“The electric Range Rover has to be a Range Rover first,” Lennard Hoonik, COO at parent company JLR, told Motortrend last summer.

Kia’s futuristic, affordable EV4 sedan will launch in 2025

Kia certainly sparked interest when it unveiled the concept model of the EV4 in 2023. The sedan’s futuristic design and electric range capacity, combined with the promise of affordability, showed that Kia was ready to make bold moves to diversify its EV lineup.

But two big questions came up: When would the EV4 actually launch, and would the smaller sedan/hatchback ever launch stateside, given American's preference for larger vehicles.
