A new study concluded that just a 2 degree (C) increase in temperature could lead to flooding in some places, droughts in others
The report titled Turn Down the Heat: climate extremes, regional impacts, and the case for resilience, marks Bangladesh as one of the world’s “potential impact hotspots” threatened by extreme river floods, more intense tropical cyclones, rising sea levels and very high temperatures.
Released yesterday, the report assesses the impacts of a 2 to 4C temperature rise on agriculture and livelihood security in sub-Saharan Africa; the rise in sea-level, loss of coral reefs and devastation to coastal areas likely in South East Asia; and the fluctuating water resources in South Asia.
It warns of major threats to food production, livelihoods and infrastructure in Bangladesh, as well as a slowdown in poverty reduction that will affect millions in the country’s coastal areas.
“Bangladesh faces particularly severe challenges with climate change threatening its impressive progress in overcoming poverty,” said Johannes Zutt, World Bank country director for Bangladesh.
Cyclone Sidr (2007) exposed 3.45 million households to inundation in Bangladesh and the potential return of a similar cyclone in 2050 could expose 9.7 million people to more than 3 ms of inundation, affecting agriculture and lives, the report says.
It warns that even 20 to 30 years from now, shifting rain patterns could leave some areas under water and others without enough water for power generation, irrigation or drinking.
Unless action is taken now to limit carbon release in the atmosphere, the report says that more extreme droughts and floods, and declines in food production, will be inevitable for South Asia.
