Climate in a narrow sense is usually defined as the “average weather”, or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years. The classical period is 30 years, as defined by the WMO. These quantities are most often surface variables such as temperature, precipitation, and wind. The climate of a location is affected by its latitude, terrain, altitude, persistent ice or snow cover, as well as nearby oceans and their currents. Climate in a wider sense is the state, including a statistical description, of the climate system
Carbon dioxide (CO2)
Nitrous Oxide (N2O)
Sulfur Hexafluoride (SF6)
The annual mean rainfall exhibits increasing trends in Bangladesh. Decadal rain anomalies are above long term averages since 1960s.
Serious and recurring floods have taken place during 2002, 2003, and 2004. Cyclones originating from the Bay of Bengal have been noted to decrease since 1970 but the intensity has increased.
Water shortages has been attributed to rapid urbanization and industrialization, population growth and inefficient water use, which are aggravated by changing climate and its adverse impacts on demand, supply and water quality.
Salt water from the Bay of Bengal is reported to have penetrated 100 km or more inland along tributary channels during the dry season.
The precipitation decline and droughts has resulted in the drying up of wetlands and severe degradation of ecosystems.
32 cm SLR
88 cm SLR
Flood, flash flood, droughts, salinity, precipitation pattern
Rice and wheat production reduce 8% and 32% respectively by 2050
Fisheries impacted negatively (salinity intrusion, fisheries recruitment etc)
Flood/flash flood timing
Increased precipitation in the catchments bring more water which is beyond drainage capacity, infrastructure insufficient capacity
Urban flooding, drainage congestion (drainage infrastructure and channels are insufficient)
Salinity intrusion (irrigation, domestic use, drinking water)
Trans-boundary water issues
Increased water and vector borne diseases
Increased diseases due to salinity and water logging
Sanitation, safe drinking water
Increased/ storm surges, wave heights, turbulent sea
Salinity intrusion, soil salinity, ground water salinity
Areas with high economic importance (Export Process Zone, ports etc)
Most vulnerable groups
Women, children, elderly
Disadvantaged groups (ethnic, fisher, Sundarban dependent etc)
Increased SST potential for more cyclone landfall and storm surges
Increased rain during monsoon/post monsoon in upper catchment & or within Bangladesh leads to more floods and disasters
Water shortage and higher temperature results into acute and more spread droughts
Infrastructures: threat past gains and needs new design
UNFCCC, Kyoto protocol, Negotiation, funding mechanism
Kyoto Protocol, UNFCCC ratified
A large number of studies
NAPA, National communication
International process (Negotiation)
Climate Change Cell
Championed the concern in country/abroad, active earlier
Work closely/partnerships with Government entities (NAPA, national communication, etc.)
Part of country delegation to COP/MOP
Numerous studies, assessments (over 100)
Civil society initiatives are on the ground, piloting and demonstration and building community resilience
Government learns from these and uptake for scale up and institutionalization
