The La Nina climate change and the devastating floods in southern Africa were caused by climate change

A study released on Thursday revealed that a "perfect storm" of climate changes and La Nina weather patterns caused catastrophic flooding in southern Africa during the past month. The floods killed 200 people and affected hundreds of thousands more, according to the study.

World Weather Attribution's report showed that extreme rainfall events have increased in intensity by 40% since preindustrial time. This is a clear indication that warming ocean temperatures, linked to greenhouse gas emission, are to blame. The current conditions of La?Nina also made things worse.

The study stated that severe flooding has been causing havoc in Mozambique and other countries, including South Africa, Zimbabwe, and Eswatini. "Some areas received over a year of rain in only a few days," the study noted. The Kruger Park in South Africa was closed due to burst rivers. Repairs will cost millions.

WWA reported that "data confirms a clear trend toward more violent rainstorms." This effect was compounded due to the current La Nina which brings naturally wetter conditions in this part of the world but now operates within a more moisture-rich environment.

La Nina is the temporary cooling in temperatures of the central and eastern Pacific Ocean. World Meteorological Organization predicted a weak La Nina for this cycle but warned of the increased risk of flooding and droughts due to warmer than normal sea temperatures.

Izidine Pinto is a senior climate researcher and co-author at the Royal Netherlands Meteorological Institute. She said that climate change caused by humans has a devastating impact on those who are in its path.

"Our analysis clearly demonstrates that the continued burning of fossil-fuels increases extreme rainfall and makes it more severe." (Reporting and editing by Alison Williams; Reporting by Tim Cocks)
