Extreme heat threatening cities 0
Rapid population growth and global warming are increasing exposure to extreme heat in cities, aggravating health problems and making moving to urban areas less beneficial for the world’s poor, according to a study released Monday.
The rise is affecting nearly a quarter of the world’s population, said the report published in the “Proceedings of the National Academy of Sciences.”
In recent decades, hundreds of millions of people have moved from rural areas to cities where temperatures are generally higher because of surfaces such as asphalt which trap heat and a lack of vegetation.
Scientists studied the maximum daily heat and humidity in more than 13,000 cities from 1983 to 2016.
Using the so-called “wet-bulb globe temperature” scale, a measure that takes into account heat and humidity, they defined extreme heat as 30 degrees Celsius (86 degrees Fahrenheit).
The researchers then compared weather data with statistics on the cities’ population over the same 33-year period.
They calculated the number of days of extreme heat in a particular year by the population of the city that year to come up with a definition called person-days.
The authors found that the number of person-days in which city dwellers were exposed went from 40 billion per year in 1983 to 119 billion in 2016.
Cascade Tuholske at Columbia University’s Earth Institute, a lead author of the study, said the rise “increases morbidity and mortality.”
“It impacts people’s ability to work, and results in lower economic output. It exacerbates pre-existing health conditions,” he said in a statement.
Population growth accounted for two-thirds of the exposure spike, with actual warming temperatures contributing a third, although proportions varied from city to city, they wrote.
Bangladesh’s capital Dhaka was the worst-affected city, seeing an increase of 575 million person-days of extreme heat over the study period.
That was largely attributable to its population soaring from around four million in 1983 to around 22 million today.
The authors said the patterns they found in Africa and South Asia, “may crucially limit the urban poor’s ability to realize the economic gains associated with urbanization.”
They added that “sufficient investment, humanitarian intervention, and government support” would be needed to counteract the negative impact.
The study was carried out by researchers at New York’s Columbia, University of Minnesota Twin Cities, the University of Arizona at Tuscon and the University of California, Santa Barbara.

Southern Cameroons Crisis: Yerima calls on Ambazonians to ignore Dion Ngute 0
INTERIM GOVERNMENT STATEMENT on DION NGUTE’S VISIT TO THE NORTHERN ZONE FROM 5TH–8TH OCTOBER 2021
Yesterday, 03 October 2021, Adolphe Lele Lafrique communicated that Joseph Dion Ngute, the Prime Minister of La Republique du Cameroun, will be “undertaking a peacebuilding visit” to the Northern Zone of Ambazonia from Tuesday, the 05 to Friday 08 October 2021.
The Interim Government of Ambazonia considers this scam an act of utter contempt and disrespect to the people of Southern Cameroons and a flagrant violation of our sovereignty. It is particularly cruel that this visit takes place a few days after the monstrous regime in Yaoundé released hundreds of army and gendarme officers to the Northern zone with the exclusive order to rape our women and kill our people.
This action from Dion Ngute and his master in Yaoundé confirms what the opinion of all Ambazonians is, that La Republic du Cameroun has a disregard for the lives of our people. This move is proof of Yaoundé’s steadfast commitment to deception.
After consultation with Generals and Commanders in Ground Zero, major military operations have been planned in the Northern zone over the next few days. Consequently, our military leaders cannot guarantee the safety of anyone who ventures outside their home.
Because the safety of our people is of paramount importance, your Interim Government now wants to counsel that all law-abiding Southern Cameroonians in the Northern Zone must stay at home during these four days. All emergency activities within this zone of Ambazonia must be assumed with extreme caution.
Fellow Ambazonians, this is a difficult journey we have embarked upon. No one can say with utmost certainty what the outcome will be, but we must remain focus and keep our eyes on the prize despite the games from the murderous regime in Yaoundé. We shall not accept anything less than total independence.
God Bless Ambazonia. It’s Total Independence or Resistance forever.
Thank You, and God Bless You
Dabney Yerima
