Laborers and Street Vendors in Mali Find No Respite as Deadly Heat Wave Surges Through West Africa

Street vendors in Mali's capital of Bamako peddle water sachets, ubiquitous for this part of West Africa during the hottest months. This year, an unprecedented heat wave has led to a surge in deaths, experts say, warning of more scorching weather ahead as effects of climate change roil the continent.

The heat wave began in late March, as many in this Muslim majority country observed the holy Islamic month of Ramadan with dawn-to-dusk fasting.

On Thursday, temperatures in Bamako reached 44 degrees Celsius (111 Fahrenheit) and weather forecasts say it's not letting up anytime soon.

The city's Gabriel-Touré Hospital reported 102 deaths in the first four days of the month, compared to 130 deaths in all of April last year. It's unknown how many of the fatalities were due to the extreme weather as such data cannot be made public under the regulations imposed by the country's military rulers.

Cheikh A Traoré, Mali’s general director for health, said significantly more elderly people have died during this period although there were no statistics available due to the measures.

Mali has experienced two coups since 2020, leading a wave of political instability that has swept across West and Central Africa in recent years. Along with its political troubles, the country is also in the grip of a worsening insurgency by militants linked to al-Qaeda and the ISIS group.

The Red Cross Red Crescent Climate Centre says that a lack of data in Mali and other West Africa countries affected by this month's heat wave makes it impossible to know how many heat-related deaths there were but estimated that the death toll was likely in the hundreds if not thousands.

The heat is also endangering already vulnerable children in Mali — 1 million under the age of 5 were at risk of acute malnutrition at the end of 2023 due to protracted violence, internal displacement, and restricted access to humanitarian aid, according to the World Food Program.

Professor Boubacar Togo, head of pediatrics at Gabriel-Touré, told The Associated Press that the hospital has had six cases of meningitis in children in the last week, an unusually high number. He also added that there were many illnesses with diarrhea as a leading symptom. Togo did not elaborate or offer specific data.

To protect children from the worst of the heat, Mali's military rulers have shortened the school day, to end before 1 p.m. instead of at 5.30 p.m. during the heat wave. But on the streets of Bamako, workers say they have no choice but to go out and brave the extreme heat.

“Either I work and risk my health or I stop working for the most of the day and I earn nothing,” said 25-year-old driver Amadou Coulibaly, who offers rides on his motorbike for a small fee.

With the political instability, many foreign investors are leaving Mali. Rolling power cuts and fuel shortages have forced companies to shut doors, exacerbating an already dire economic situation.

Despite the heat, 30-year-old welder Somaila Traoré worked in his shop alongside a dozen employees, urging them to work faster.

“We’ve got to finish the job before the power cuts,” he said.

An analysis published Thursday by the World Weather Attribution — an international team of scientists looking at how human-induced climate change impacts extreme weather — said the latest heat wave in the Sahel, a region in Africa south of the Sahara that suffers from periodic droughts, is more than just a Malian record-breaker.

“Our study found that the extreme temperatures across the region simply wouldn’t have been possible without human-caused warming,” said Clair Barnes, the lead author and a researcher at Imperial College London.

The researchers say climate change has made maximum temperatures in Burkina Faso and Mali hotter by 1.5 degrees Celsius (2.7 degrees Fahrenheit) — something that may not have happened “if humans had not warmed the planet by burning fossil fuels.”

With sustained warming temperatures, the trend would continue, with similar events likely once every 20 years, the study said.

“This result is a warning for both the region and the world,” Barnes said. “Extreme heat can be incredibly dangerous and will become more of a threat as the world continues to warm.”



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
