Measures needed to face fallout

Experts have agreed that warming will record a new high in next five years necessitating flow of global aid to face the fallout of climatic changes. The recent meeting on climate change in New York debated ways towards a multilateral framework for action on climate change for the period after 2012.In fact, countries like Bangladesh will have to put an extra efforts in facing more intensive and frequent floods, cyclones, tidal surges and storms across the globe as the country is found to be vulnerable to climatic changes.Global efforts should also urgently required in facing those adverse impacts of climatic changes worldwide with a special focus on least developed and small island countries.Bangladesh marked a slight rise in temperature in the past years. It estimated temperature had marked a rise of about 0.0037 degree Celsius over 40 years that has changed the character of the winter and the rains. The duration of winter has been shortened to a degree that it has come to be known as ‘warm winter’. The Met Office in 2004 recorded the highest rainfall in 50 years in a day. Experts blamed population growth, more land use, melting of ice caps in the poles, global warming of ozone layer, and jhum farming on highland in the upstream causing continuous silting in rivers for environmental degradation. Unplanned development, especially construction of dams and roads, and emission of toxic chemicals from industries and brick kilns have also been taking a toll on the environment. The slight change in climate has adversely affected the country in many ways, bringing about long dry spells, heavy downpour, cyclones, floods, storms, surges, increase in salinity and fresh water depletion with their knock-on effects on the ecosystem. It also caused in the past few years problems such as outbreaks of diseases like kala ajar, dengue fever, leishmaniasis disease, cholera and meningococcal meningitis. It has been causing crop failure and near-famine situations during a particular period of the year and has been threatening food security, according to an international study on climatic changes. Bangladesh has no record of sea-level rise although the international environmentalists predict that Bangladesh would be the worst victim of the happening. The speed and magnitude of climate change affect the success of species, population, and community adaptation. The rate of climatic warming may exceed the rate of shifts in certain species ranges; these species could be seriously affected or even disappear because they are unable to adapt. Some plant and animal species and natural systems could be adversely affected by regional climatic variations that correspond to a less than 1°C mean global warming by 2100. Hence, countries like Bangladesh will need global assistance in devising ways and means to survive dangers of climate change.
