JOHANNESBURG (AP) \u2014 Human-caused climate change worsened recent torrential rains and floods<\/a> that devastated parts of southern Africa, killing more than 100 people and displacing hundreds of thousands, researchers said Thursday.<\/p>\n

A study by the World Weather Attribution, which analyzed the recent heavy rainfalls that caused severe flooding<\/a> in parts of South Africa, Mozambique and Zimbabwe, showed that the region experienced a year\u2019s worth of rain in a period of 10 days.<\/p>\n

It resulted in widespread damage to housing and infrastructure estimated to run to millions of dollars, while humanitarian agencies say there is an escalating crisis for people displaced and facing hunger, disease outbreaks and a lack of health services because of the destruction<\/a>.<\/p>\n

Many homes and buildings in Mozambique<\/a> were completely submerged under water and dozens of hospitals and clinics were destroyed, while roads and bridges were swept away in the South African provinces of Limpopo and Mpumalanga and parts of Zimbabwe.<\/p>\n

The study was conducted by scientists from across the world using peer-reviewed methods to assess the impact of climate change on severe weather patterns and events.<\/p>\n

A magnitude occurring once in 50 years<\/p>\n

The data obtained from the recent downpours, the rare magnitude of which occurs roughly once every 50 years, confirmed a \u201cclear move toward more violent downpours,\u201d the study said.<\/p>\n

It was also compounded by the current La Nina weather phenomenon which naturally brings wetter conditions in the southern Africa region but was now operating within a much warmer atmosphere.<\/p>\n

\u201cOur analysis clearly shows that our continued burning of fossil fuels is not only increasing the intensity of extreme rainfall, but turning events that would have happened anyway into something much more severe,\u201d said Izidine Pinto, a senior climate researcher at the Royal Netherlands Meteorological Institute.<\/p>\n

Pinto, who co-authored the study, said the climate models used struggled to pinpoint exactly how much worse the recent floods were made by climate change, but that a 40% increase in the intensity of the rains would be impossible to explain without human-caused climate change.<\/p>\n

\u201cIt means what would have already been a serious period of heavy rain has been transformed into a more violent deluge that communities are not equipped to deal with,\u201d he said.<\/p>\n

Africa contributes only 3% to 4% of global emissions, according to the United Nations, and yet is one of the most vulnerable to the impacts of climate change. The floods and previous crises like cyclones<\/a> in southern Africa cause hundreds of millions to billions of dollars\u2019 worth of damage in what are largely poor countries and the continent has urged richer nations to help more<\/a> with climate-related disasters.<\/p>\n

Around 1.3 million people across southern Africa were affected by this month\u2019s floods, The World Health Organization said.<\/p>\n

Rainfall exceeds expectations<\/p>\n

The affected regions in southern Africa are no strangers to heavy downpours and flooding, but scientists were alarmed by the magnitude of the recent events.<\/p>\n

\u201cThis event was a surprise to us because we have experienced the previous ones 25 years ago, which flooded the same areas,\u201d said Bernardino Nhantumbo, a researcher with the Mozambique weather service. \u201cThere are places that have recorded in two to three days the rainfall that was expected for the entire rainy season, so this was very challenging to accommodate in any circumstances.\u201d<\/p>\n

Nine international rivers flow downstream to Mozambique and signficant damage is expected following such an event due to heavy rainfall as well as the stream flow, Nhantumbo said.<\/p>\n

\u201cWe forecast well because we have different models, but these are those events that even with a good forecast you cannot hold the damages that are associated,\u201d he said.<\/p>\n

The central and southern parts of Mozambique were the hardest hit, with the Gaza provincial capital of Xai-Xai and the nearby town of Chokwe largely submerged under water.<\/p>\n

Researchers seek Africa-focused climate models<\/p>\n

The researchers also have called for the development of climate models in Africa in order to best understand the dynamics and extent of the impact of climate change in the continent\u2019s various regions.<\/p>\n

The lack of climate models developed in Africa was part of the reason why most models struggled to pinpoint exactly how much worse the recent floods were made by climate change, according to Friederike Otto, professor of climate science at the Centre for Environmental Policy at Imperial College in London.<\/p>\n

\u201cAll climate models that we have that are freely available are developed outside of Africa. They are all developed within climate modeling centers in the U.S., Europe and some in Asia,\u201d Otto said. \u201cBut there is not a single climate model that is developed in Africa. Because of this they are usually designed so that they get the weather best in the regions they are made for, and that is true for all models.\u201d<\/p>\n
