What is climate?
Climate is the average weather of 30-35 years in an area or geographical area. Rapid climate change is a casual phenomenon in today's world. As a result of this climate change, the earth's temperature is slowly rising, which is better known as global warming. In scientific terms, this is called the greenhouse effect. Due to the increase in global temperature, various types of disasters are increasing such as heavy rains, droughts, flash floods, droughts, tidal surges, cyclones etc. As a result, the amount of loss of knowledge and property is increasing. Due to this, crores of rupees are being wasted every year.
Climate change caused by global warming is having a devastating effect on the world's natural environment. As a result of these changes, sea surface warming is increasing and the seasonal continuity of the weather is being disrupted. For this reason, Bangladesh is one of the countries in the world that will be affected. The main reason is the geographical location of Bangladesh, socio-economic infrastructure and dependence on natural resources. Climate change will severely damage all sectors of Bangladesh, especially infrastructure, health, housing, agricultural production, natural environment, all public welfare services and food security, which will hamper our sustainable socio-economic development process and economic activities.
The effects of climate change
The impact of climate change has been greatest in agriculture. Countries with agricultural economies are being adversely affected. Over the last century, carbon dioxide has increased by 23%, nitrous oxide by 19%, and methane by 100% (Och: Fourth Report 2006). In order to survive, people have to struggle with various adversities. The biggest adversity or threat of the present time is climate change. The part of the population that suffers the most from this change is the poor. Due to the coastal geographical location, overpopulated population, insufficient natural resources and over-reliance on it, etc., the danger of Bangladesh is very dire. There is an urgent need to raise awareness at all levels to protect Bangladesh from the potential damage of climate change.
Climate change is a regular natural phenomenon. But greatly influenced by human actions. Various human activities have accelerated climate change. The world is warming and developing countries like Bangladesh are changing the type of weather and the seasons. Och: According to the survey report-
The average annual temperature in Bangladesh in the last 14 years (1985-1998) in May was 1C. And 0.5 s in November. Increased.
The salinity of soil in Bangladesh has increased to about 10,500,000 ha. (730,000 hectares, 2009-10)
Bangladesh's average rainfall has increased, with severe floods recurring in 1986, 1996, 2002, 2003, 2004 and 2006.
Number of cyclones increases in Bay of Bengal (Sidr, Aila, Nargis)
In summer, sea salt water enters rivers up to 100 km inland.
Climate change in Bangladesh has already begun. According to a research report published in the year 2000, the coast of Cox's Bazar is 7.8 mm per year. Sea level rise has been observed at a rate. In the last four decades, about three thousand square kilometers of Bhola Island has been submerged in sea water. Reviewing various research reports, it can be seen that by 2100, the sea level is 1 m. Could be high, which could submerge 16.3 percent of the total area of Bangladesh. According to the Department of Public Health Engineering, the water level in the Upper Barind area of Rajshahi was 46 feet in 1991, 62 feet in 2000 and 93.34 feet in 2006. Normal floods inundate about 20 percent of the country's total area. Currently, both the number and intensity of floods have increased. Strong cyclones Nargis and Aila hit just two years after the catastrophic cyclone Sidr struck on November 15, 2006, and Mahasen (partial) hit May in 2013, devastating agriculture.
