  Straddling the Tropic of Cancer, Bangladesh's climate is tropical, with a mild winter from October to March and a hot, humid summer from March to June. The country has never recorded an air temperature below 0 °C (32 °F), with a record low of 1.1 °C (34.0 °F) in the northwest city of Dinajpur on 3 February 1905. A warm and humid monsoon season lasts from June to October and supplies most of the country's rainfall. Natural calamities, such as floods, tropical cyclones, tornadoes, and tidal bores occur almost every year, combined with the effects of deforestation, soil degradation and erosion. The cyclones of 1970 and 1991 were particularly devastating, the latter killing approximately 140,000 people.
  
  In September 1998, Bangladesh saw the most severe flooding in modern history, after which two-thirds of the country went underwater, along with a death toll of 1,000. As a result of various international and national level initiatives in disaster risk reduction, the human toll and economic damage from floods and cyclones have come down over the years. The 2007 South Asian floods ravaged areas across the country, leaving five million people displaced, with a death toll around 500.
