Those who become homeless due to climate changes are called climate refugees. Researchers have given different information on their number in Bangladesh. But it is more than 8 million now.
A standout amongst the most sensitive effects will be the constrained development of individuals all through Bangladesh as a consequence of losing their homes, grounds, property and employments to the impacts of environmental change.
While it is difficult to anticipate with complete precision what number of individuals will be dislodged by environmental change, the best ebb and flow gauges express that rising sea levels alone will uproot 18 million Bangladeshis inside the following 40 years.
Bangladesh is one of the top countries worldwide with the most astounding rate of populace living in low-lying coastal zones. About 5.7 million people have lost their home last 6 years because of climate change and natural disaster. As many as 200,000 juvenile and woman of Koyra, Dacope, Paikgasa, Mongla, Sharonkhola, Ashashuni and Shamnagor Upazilas are in breeding health risk.

Climate change increments both recurrence and intensity of natural disasters, like recent severe floods in 1988, 1998, 2004, 2007 and 2010; Cyclones and tidal surges in 1991, 1998, 2000, 2004 and 2207.

The word frequently connected with Dhaka, the capital of Bangladesh, is maybe, ‘overpopulated.’ It is not really shocking to discover the Bangladesh capital among the most noticeably awful urban areas to live in on the Economist Intelligence Unit's 2015 positioning.

Around 400,000 people have come to Dhaka for their livelihoods from different parts of the country and 70 percent people living in slums are climate refugees.

China, the US, the European Union, India, the Russian Federation, Japan, and Canada are the top carbon dioxide (CO2) emitters. These data include CO2 emissions from fossil fuel combustion, as well as cement manufacturing and gas flaring. Together, these sources express to an expansive extent of aggregate worldwide CO2 emanations. Outflows and sinks identified with changes in area use are excluded in these evaluations.

Research report of Boden, T.A., Marland, G., and Andres, R.J. says that China emit 28% global CO2 producing from fossil fuel combustion and some industrial processes. Besides, USA emit 16%, Russia emit 6%, India emit 6% & Japan emit 4% global CO2.

Only five countries are liable for 60% of emissions. But their impact also goes to Bangladesh fatally. This is really shocking news.

Due to these emissions, different types of natural calamities are occurring and people become homeless, landless. Now, Bangladesh needs cooperation of major Carbon emitting nations. Otherwise climate refugee problem will hinder all developments of this country. The privilege to satisfactory housing is a fundamental human right under the International Covenant on Economic, Social and Cultural Rights (ICESCR) as a component of a sufficient way of life.

Watched and anticipated environmental change will influence the privilege to sufficient housing by sudden and moderate onset calamities that impact lasting removal from the zones of source to the regions of destination.

A more intelligent policy is important to address the issue for assurance of climate refugees. In climate provisions, climate related movement is recognised as an issue countries need to follow up on as a major aspect of modification strategies.

Be that as it may, there is no express protection existing for those uprooted due to natural changes or calamities. There is a requirement for an organised methodology under the UNFCCC and the most unprotected countries ought to ask UNFCCC to make a move towards to remuneration and protection for Climate Refugees of Bangladesh.
