Carbon-hungry tulip trees could help fight global warming

Tulip trees could help us fight global warming because of the kind of wood they are made of, scientists believe.

A chance finding at a botanic garden revealed the special type of wood that appears especially good at storing carbon.

Trees are natural carbon sinks that remove CO2 from the atmosphere, where it contributes to global warming.

But it is believed ancient tulip trees, also known as liriodendron, may have evolved millions of years ago to store larger amounts of carbon.

“It was bang in the middle of when the planet was undergoing a big change in atmospheric CO2 levels,” said Raymond Wightman, who runs advanced microscopes at Cambridge University's Sainsbury Laboratory.

“The planet went from very high CO2 levels to then relatively low CO2 levels. The plants might have adapted,” Dr Wightman, a co-author of the new research, told The National.

“We’re just starting to wonder, is it something about this new wood structure that allows it to lock in more carbon?”

The species are found in North America and Asia and grow quickly, which could make them suitable for newly planted forests.

They are already used in plantations in parts of East Asia to “lock in” carbon, said a second co-author, Jan Lyczakowski.

Their rapid growth, as well as their hunger for carbon, may both be linked to the special kind of wood, an “intermediate” type between hardwood and softwood.

It was discovered by British and Polish researchers who took samples from Cambridge University's botanic garden, where the Sainsbury Laboratory is housed.

“We just decided, summer before last, just because we could, to survey as many trees and shrubs in the botanic garden as possible,” Dr Wightman said.

Preserved in liquid nitrogen at -210°C and magnified by 50,000 times under a microscope, the tulip tree samples came as a surprise to scientists.

The two surviving types of tulip tree both have much larger fibres, known as macrofibrils, than their hardwood relatives.

“Both of them had a structure that we’ve not seen before, and we’ve looked at a lot of wood structures in our microscope,” said Dr Wightman.

Using trees as a carbon sink is a common green initiative, especially as they can bring other benefits such as shade and wildlife habitats.

Research has found that planting as many as a trillion new trees on Earth could put a huge dent in the planet's carbon problem.

There are also man-made techniques, known as carbon capture and storage, that claw back CO2 waste before it hits the atmosphere.

However, an over-reliance on these methods can be seen by environmentalists as greenwashing that avoids cutting CO2 emissions in the first place.

The article Convergent and adaptive evolution drove change of secondary cell wall ultrastructure in extant lineages of seed plants, by Jan Lyczakowski and Raymond Wightman, is published in the journal New Phytologist.

Tips to stay safe during hot weather
  • Stay hydrated: Drink plenty of fluids, especially water. Avoid alcohol and caffeine, which can increase dehydration.
  • Seek cool environments: Use air conditioning, fans, or visit community spaces with climate control.
  • Limit outdoor activities: Avoid strenuous activity during peak heat. If outside, seek shade and wear a wide-brimmed hat.
  • Dress appropriately: Wear lightweight, loose and light-coloured clothing to facilitate heat loss.
  • Check on vulnerable people: Regularly check in on elderly neighbours, young children and those with health conditions.
  • Home adaptations: Use blinds or curtains to block sunlight, avoid using ovens or stoves, and ventilate living spaces during cooler hours.
  • Recognise heat illness: Learn the signs of heat exhaustion and heat stroke (dizziness, confusion, rapid pulse, nausea), and seek medical attention if symptoms occur.

'The worst thing you can eat'

Trans fat is typically found in fried and baked goods, but you may be consuming more than you think.

Powdered coffee creamer, microwave popcorn and virtually anything processed with a crust is likely to contain it, as this guide from Mayo Clinic outlines: 

Baked goods - Most cakes, cookies, pie crusts and crackers contain shortening, which is usually made from partially hydrogenated vegetable oil. Ready-made frosting is another source of trans fat.

Snacks - Potato, corn and tortilla chips often contain trans fat. And while popcorn can be a healthy snack, many types of packaged or microwave popcorn use trans fat to help cook or flavour the popcorn.

Fried food - Foods that require deep frying — french fries, doughnuts and fried chicken — can contain trans fat from the oil used in the cooking process.

Refrigerator dough - Products such as canned biscuits and cinnamon rolls often contain trans fat, as do frozen pizza crusts.

Creamer and margarine - Nondairy coffee creamer and stick margarines also may contain partially hydrogenated vegetable oils.

Basquiat in Abu Dhabi

One of Basquiat’s paintings, the vibrant Cabra (1981–82), now hangs in Louvre Abu Dhabi temporarily, on loan from the Guggenheim Abu Dhabi. 

The latter museum is not open physically, but has assembled a collection and puts together a series of events called Talking Art, such as this discussion, moderated by writer Chaedria LaBouvier. 

It's something of a Basquiat season in Abu Dhabi at the moment. Last week, The Radiant Child, a documentary on Basquiat was shown at Manarat Al Saadiyat, and tonight (April 18) the Guggenheim Abu Dhabi is throwing the re-creation of a party tonight, of the legendary Canal Zone party thrown in 1979, which epitomised the collaborative scene of the time. It was at Canal Zone that Basquiat met prominent members of the art world and moved from unknown graffiti artist into someone in the spotlight.  

“We’ve invited local resident arists, we’ll have spray cans at the ready,” says curator Maisa Al Qassemi of the Guggenheim Abu Dhabi. 

Guggenheim Abu Dhabi's Canal Zone Remix is at Manarat Al Saadiyat, Thursday April 18, from 8pm. Free entry to all. Basquiat's Cabra is on view at Louvre Abu Dhabi until October
