CLIMATE CRISIS

‘A code red’: Will Europeans change their habits after climate crisis ‘reality check’?

Europe was hit by a series of extreme weather events this summer that left rivers dry and forests burned but will people wake up to the "reality check" or go on eating as much steak and taking the plane?

Wildfires and storms. Rivers at record lows. Parched crops withering in the fields. For many Europeans, this year’s scorching summer means climate change is increasingly hard to ignore.

After months of cloudless days and drought, the weather has been one of the major themes of media coverage — and discussions during family gatherings — over the annual August holiday period.

“This summer has seen a series of extreme weather events,” French government spokesman Olivier Veran told a first press conference after he and
the government returned to the office last week.

It had been a “complete reality check, even for the most sceptical,” he said.

France experienced its second-hottest summer on record, its driest one since 1976 and the worst in terms of the loss of forestry to wildfires since
2003, he said.

In recent months, some French villages have needed to be supplied with water trucks as their usual sources have dried up. Fires have repeatedly
ravaged pine forests near Bordeaux.

Even in the normally verdant Alps, cheese makers complain that their cows are producing less milk than usual because their pastures are dried up.

The picture is similar across Europe.

In Italy, the collapse of the country’s largest Alpine glacier in July sparked an avalanche that killed 11 people.

“The year 2022 in terms of extreme climate events is code red,” said the head of environmental group Legambiente, Stefano Ciafani, in an August report.

After a punishing drought, around 400 Spanish wildfires destroyed 290,000 hectares (72,000 acres) of forest — way above the recent average of 67,000 hectares a year.

As reservoir water levels plunged, a previously flooded centuries-old church and a huge megalithic complex emerged from their depths.

And a year after shocking major floods that claimed more than 180 lives in Germany, the country saw the Rhine river — a crucial trade route — shrink to levels that were barely navigable.

Jets and steak

The question for experts and campaigners is how much the sweltering summer of 2022 will translate into political change and lifestyle shifts from
consumers.

As people return to work, France’s green EELV party has been setting the news agenda with eye-catching proposals to crack down on executive jets as well as private swimming pools.

“We’ve just lived through a summer when we’ve seen the real impact of climate change for the first time and what are we doing? What are we prepared to do?” said leading MP Sandrine Rousseau.

She found herself at the centre of a national furore this week after suggesting men needed to cut down on emissions-heavy barbecued steak which
they saw as a “symbol of virility.”

“What has become quite obvious is that climate impacts and climate hazards are happening throughout Europe to differing degrees and with differing hazards,” Carolina Cecilio from the E3G think-tank told AFP.

“It’s not limited to southern Europe, which is more used to periods of drought and forest fires,” she added.

Greater awareness in big EU member states such as France, Germany and Italy could help “shape the political agenda,” Cecilio said.

Energy crisis

Some campaigners see an opportunity for real change in the energy crisis that has gripped Europe since Russia began turning off its gas deliveries
following its invasion of Ukraine.

“I think that the scale and the coming together of overlapping crises should drive us to really question our use of energy,” Lola Vallejo from the
IDDRI think-tank told AFP.

“We can only hope that the summer we’ve just lived through will play a role in accelerating our collective will,” said Vallejo.

But a working paper from the Organisation for Economic Cooperation and Development in June laid bare the scale of the challenge.

Analysing survey results from 20 mostly rich countries, its experts concluded that climate change awareness was high, with 60-90 percent of people
understanding it was caused by human activity.

The problem was their willingness to change.

“Respondents were generally unwilling to limit their beef or meat consumption significantly. Few are willing to limit driving or heating or cooling their homes by a lot,” the authors wrote.

Italy’s elections on September 25 will be a test of how much climate change has really hit home, with campaigning so far dominated by worries about the cost of living.

Polls suggests that the next government could be a coalition of far-right and right-wing parties who have put it low on their agenda.

Does Spain use cloud seeding?

Some voices online blamed cloud seeding for flash flooding in Dubai recently. Does Spain use this weather modification technique and is it being harnessed as a means of combatting severe drought in the country?

Does Spain use cloud seeding?

The internet was awash with images of dramatic flooding in the UAE two weeks ago, in which parts of the country saw more rainfall in a single day than it usually does in an entire year on average.

The UEA government stated that it was the most rainfall the country had seen in 75 years and an incredible 10 inches of rain fell in the city of Al Ain.

Predictably, the freak weather event sparked fierce internet debate about the causes and consequences among climate change activists and climate change sceptics. The cause, in particular, struck a chord with certain subsections of the internet and many were asking the same question: did ‘cloud seeding’ cause this biblical downpour?

But what exactly is cloud seeding? Does Spain use it? And with the country’s ongoing drought conditions, should it be using it?

What is cloud seeding?

According to the Desert Research Institute: “Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by introducing tiny ice nuclei into certain types of subfreezing clouds. These nuclei provide a base for snowflakes to form. After cloud seeding takes place, the newly formed snowflakes quickly grow and fall from the clouds back to the surface of the Earth, increasing snowpack and streamflow.”

Cloud seeing is used by countries around the world, not only in the Middle East but in China and the U.S, usually in areas suffering drought concerns. The process can be done from the ground, with generators, or from above with planes.

Does Spain use cloud seeding?

Sort of, but on a far smaller scale and not in the same way other countries do. In places like China and the U.S, where large swathes of the country are at risk of drought, cloud seeding is used to help replenish rivers and reservoirs and implemented on an industrial scale.

In Spain, however, the technique has been for a much more specific (and small scale) reason: to avoid hailstorms that can destroy crops.

This has mostly been used in the regions of Madrid and Aragón historically.

But cloud seeding isn’t something new and innovative, despite how futuristic it might seem. In fact, Spain has a pretty long history when it comes to weather manipulation techniques. Between 1979 and 1981, the first attempts to stimulate rainfall took place in Spain, coordinated by the World Meteorological Organisation.

“In 1979, in Valladolid, different techniques were developed to observe the local clouds but they did not meet any possible conditions for cloud seeding experiments. The project came to a standstill,” José Luis Sánchez, professor of Applied Physics at the University of León, told La Vanguardia.

This sort of cloud seeding, as used abroad, doesn’t really happen in Spain anymore. Rather, when it’s used it’s done to protect crops on a local level. Spain’s Ministry for Ecological Transition and the Demographic Challenge are responsible for authorising cloud seeding, but there are only a handful of current authorisations to combat hail, such as the one granted to the Madrid’s Agricultural Chamber combat hail in the south-east of the region.

As of 2024, it is believed that no regions have requested cloud seeding (whether by generator or plane) to ‘produce’ more rain.

So, cloud seeding isn’t currently used like it is in countries such as the U.S., China, and the UAE. But should it, and could it solve the drought issue in Spain?

Spain’s drought conditions

Spain has been suffering drought conditions for several years now. Last year the government announced a multi-billion dollar package to combat the drought conditions, and several regions of Spain have brought in water restrictions to try and maintain dwindling reservoir reserves.

At times in Spain in recent years it has felt as though another temperature or minimum rainfall record is broken every other day. The drought conditions are particularly bad in the southern region of Andalusia and Catalonia, where, despite heavy rain over Easter, reservoirs in the region are at just 18 percent capacity, the lowest level in the country.

So, could cloud seeding be used in Spain to help alleviate some of the drought conditions? Yes and no. Seeding is not the only answer to drought, but could theoretically be used as one option among many.

“It’s just another tool in the box,” Mikel Eytel, a water resources specialist with the Colorado River District, told Yale Environment 360 magazine: “It’s not the panacea that some people think it is.”

This is essentially because cloud seeding does not actually produce more rain, rather it stimulates water vapour already present in clouds to condense and fall faster. For there to be a significant amount of rainfall, the air needs significant levels of moisture.

That is to say, using cloud seeing to try and stimulate more rain may help Spain’s drought conditions in a small way, but the difference would be marginal.

“It’s not as simple and may not be as promising as people would like,” respected cloud physicist Professor William R. Cotton, wrote in The Conversation. 

“Experiments that produce snow or rain require the right type of clouds with sufficient moisture and the right temperature and wind conditions. The percentage increases are small and it is difficult to know when the snow or rain fell naturally and when it was triggered by seeding.”
