Is climate change making floods more likely - and what can be done about it?

The floods that hit the Northern Emirates recently had tragic consequences, killing seven people and forcing thousands into temporary shelters.

In recent weeks other parts of the Middle East also faced the worst effects of flooding, including Iran, where at least 80 people were killed in late July.

This came only three years after heavy rains in southern Iran caused the deaths of 76 people and an estimated $2 billion worth of damage.

In parts of the Middle East and North Africa, rainfall is becoming concentrated in shorter bursts, even if overall levels are often decreasing, said Dr Nasser Karami, a researcher in Norway who analyses the region's climate.

Added to this, he said, are the effects of development, with buildings constructed in areas that are prone to flooding.

“So the possibility of floods occurring has increased, and the possibility of damage from floods has increased,” he said.

“Big damage from flooding in the Middle East previously was about once per 10 years. Now it's every year.”

Global issue

Look further afield and a similar picture is seen.

In Seoul, the South Korean capital, rain recently fell at the fastest rate since records began more than a century ago, killing 13 people, some of whom were trapped in basements.

Parts of the Philippines, including the capital, Manila, and the island of Cebu, have been under as many as 1.2 metres of water this month.

Meanwhile, Death Valley in California not long ago experienced, in just a few hours, 43mm of rainfall, almost as much as falls in an average year.

It is no wonder that palm trees were uprooted and dozens of cars were swept away and ended up partially buried in debris.

While extreme weather events and flooding are nothing new, experts say the disturbances caused by climate change mean they are happening more often.

One reason is that a warmer atmosphere holds more moisture: a 1°C average temperature rise increases the amount of moisture by about seven per cent.

“That's basic physics,” said Bob Ward, of the Grantham Research Institute on Climate Change and the Environment, part of the London School of Economics and Political Science.

“When it does rain, you tend to get heavier rainfall, which can lead to river flooding and surface-water flooding.”

As well as intensifying rainfall, climate change is causing some storms to move more slowly, so more rain falls on a particular area and flash floods become more likely.

Research published last year by Newcastle University and the University of Bristol in the UK suggested that “slow-moving intense rainstorms” could be 14 times more common in Europe by the end of the century if little was done to reduce emissions.

An unwelcome preview of this was seen in July 2021, when lingering storms meant that Germany, Belgium and other European nations suffered devastating flooding that killed nearly 250 people.

Multiple factors

There are many other ways in which floods are becoming more of a risk in particular environments.

In some mountainous regions, such as the Appalachians of eastern and north-eastern North America, several factors are at play.

As well as an upward trend in intensity, researchers have found that more precipitation is in the form of rain, which is more likely than snow to cause flooding.

In addition, wildfires are more frequent because of climate change, and they increase the risk of mudslides and debris flows when there is heavy rain.

Vulnerable seaside populations

For coastal areas, sea-level rises caused by climate change increase the risk of floods, especially due to storm surges. Building higher and stronger sea defences can protect some, but not all, areas.

“This may be economically viable where you have concentrations of population, such as cities,” Mr Ward said. “But in less populated areas there will have to be a calculation as to whether it's worth staying there or giving up coastal population to rising sea levels.

“There are many parts of the world where we're starting to get these conversations.”

Many coastal cities, such as New Orleans, Mumbai and Shanghai, are built on river deltas, which makes them especially vulnerable.

Cities are often at risk of flooding because large areas of the ground are made from impermeable materials that do not allow the water to soak in, but things can be done to make them more resilient.

Individual buildings can be protected by what the industry calls property flood resilience measures.

These may consist of aperture barriers, such as waterproof metal barriers in front of external doors, to prevent water entering.

Another approach is to design buildings in such a way that, if they are flooded, damage is reduced. Mr Ward highlights measures such as using tiles, which will not be spoilt if water gets into a room, and placing electrical sockets higher up. It may also be preferable for the electrics to run down from the ceiling rather than up from the ground.

On a wider level, and among many other measures, governments may have to invest in improved drainage systems so that, when rains come, more water escapes.

“You have cities like London with Victorian drainage, which cannot cope,” Mr Ward said. “You need to overhaul the drainage system.”

As the world struggles to meet greenhouse gas emission targets that would limit average temperature increases to 1.5°C above pre-industrial levels, a key goal of the 2015 Paris Agreement, extreme rainfall events are set to become ever more common, and sea levels are forecast to continue to rise.

“The climate is changing because we've altered the atmosphere in a way we haven't seen in more than one million years,” Mr Ward said. “There's going to be lots of nasty shocks because of this.”

Heavily-sugared soft drinks slip through the tax net

Some popular drinks with high levels of sugar and caffeine have slipped through the fizz drink tax loophole, as they are not carbonated or classed as an energy drink.

Arizona Iced Tea with lemon is one of those beverages, with one 240 millilitre serving offering up 23 grams of sugar - about six teaspoons.

A 680ml can of Arizona Iced Tea costs just Dh6.

Most sports drinks sold in supermarkets were found to contain, on average, five teaspoons of sugar in a 500ml bottle.

Real estate tokenisation project

Dubai launched the pilot phase of its real estate tokenisation project last month.

The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.

Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Sugary teas and iced coffees

The tax authority is yet to release a list of the taxed products, but it appears likely that sugary iced teas and cold coffees will be hit.

For instance, the non-fizzy drink AriZona Iced Tea contains 65 grams of sugar – about 16 teaspoons – per 680ml can. The average can costs about Dh6, which would rise to Dh9.

Cold coffee brands are likely to be hit too. Drinks such as Starbucks Bottled Mocha Frappuccino contain 31g of sugar in 270ml, while Nescafe Mocha in a can contains 15.6g of sugar in a 240ml can.

Mia Man’s tips for fermentation

- Start with a simple recipe such as yogurt or sauerkraut

- Keep your hands and kitchen tools clean. Sanitize knives, cutting boards, tongs and storage jars with boiling water before you start.

- Mold is bad: the colour pink is a sign of mold. If yogurt turns pink as it ferments, you need to discard it and start again. For kraut, if you remove the top leaves and see any sign of mold, you should discard the batch.

- Always use clean, closed, airtight lids and containers such as mason jars when fermenting yogurt and kraut. Keep the lid closed to prevent insects and contaminants from getting in.
