Causes of Climate change:

1. Greenhouse gases: The main and actual cause of climate change is greenhouse gases,(Carbon dioxide, nitrous oxide, methane, chlorofluoro carbons, water vapour) overflow. It causes due to industrial smoke, Transport, destroy green forest, filling the river, pond.
2. Polythene: Polythene which is not destroyable or avoidable is another matter of climate change. A sunlight can not go through polythene and the warm of sunlight remains in the atmosphere without absorbing.
3. War: War is another cause of climate change. Due to war a huge amount of bomb, missile is busted. A huge amount of air polluted and a huge amount of gas outflows.
4. Higher quantity of Electric product use: Electrical goods outflows gases. Previous it was used limitedly.
5. Increase of dust in the air: increase of dust in the is another cause of climate change. Dust increases due to lacking of rain.
6. Sound: since sound can’t be deleted so it might be another cause of climate change.
7. Dust in the Sea: Due to high dust specially plastic the sea could not absorb full sunlight . As such water vapour could not create properly. For this rain decreases carbon increases.

Effects:

 Hailstorm: Hailstorm is the most common effect of climate change.

Patience and Mental health: Due to climate change (heat) people are losing their patience and mental health.

Several diseases: Due to high carbon, dust and no rain several pandemic diseases found in the world like Corona by accumulating carbon, dust in a specific area and spread it through air. Climate Change also liable for diseases.

Earthquake:  Mostly earthquake occurs due to climate change. Suppose due to climate change one area has less rainfall and the adjacent area is full of rainfall. Due to low rainfall the sea level must be reduced and to increase the sea level the nature automatically collect water from adjacent area. This may cause to move the plates under land.

Reduces lifespan: Climate change reduces life span. In ancient year people were living for 1000 years but now it came to average 60-70 years. It is observed by Wikipedia in the ancient time the weather was mostly cool and comfortable.

Rain at non seasonal monsoon: Due to climate change rain falls at non seasonal monsoon.

Temperature increase: Temperature increase is the one of the most common effect of climate change. It effects through higher carbon in the weather.

Increase of height of sea level: Due to climate change the height of sea level increases and water level decreases. Global sea level has risen about 8 inches from 1880. It occurs through short rainfall, glaciers retreating, ice sheets shrinking, subsidence.

Snow cover is decreasing : Decreasing of snow cover also causes of climate change.

Artic Sea Ice is declining: Both the extent and thickness Artic sea ice has declined rapidly over the last several decades.

Ocean acidification is increasing: Since the beginning of the revolution the acidity of surface ocean waters has been increased by about 30%. The ocean has absorbed between 20% & 30%of total anthropogenic carbon dioxide emissions in recent decades

Disappearing of Rainbows: Due to climate change we lost the rainbows.

Losses: Due to climate change

1. Many people die by thunderstorm,
2. Million hector land flooded and crops are losses,
3. Fire occurs in jungle, fire occurs in cities,
4. Green world becomes wide,
5. Animal, bird, fishes dies.
6. The natural life destroyed by climate change.
7. People losses their mental health and patience.
8. Ices of the world deceasing.

Prevention:

1. Tree planting: A matured tree absorbs 130 gram carbon in a day. Other hand Bangladesh emits 700 Kg carbon i.e. 1.9 kg i.e. 1900 gram per day. It means if Bangladesh plants1900/130= 15 tree for pee person the climate must be favourable.
2. Use filter when carbon emerged from factories, vehicles and other sources. The filter will store the carbon which might be used another positive purpose.
3. Carbon separator machine: To invent a carbon separator machine from weather.
4. Polythene production: To decline the production of polythene through strict law.
5. War control: The world should control war i.e. bombing.
6. Water distribution: As per Bangladesh previously water Inflows from several countries was 5590m3/s now it is 3370m3/s. It means the neighbour countries is not passing proper water to Bangladesh. For this dust increases and climate changes

Methodology: Hail grows when air temperature falls below -30°C (-22°F)

As per Bangladesh history:

• Minimum hail size: 5 millimetre equal to 1.5 gram

Maximum hail size: 1 kg in1986

• Latest hail size: 203-gram April 2026

It means:

To grow minimum size hail i.e. 1.5 gram -30° Celsius temperature needed

Then 203-gram hail needs (-30X1.5/203) -0.22. ° C

It means climate change effect -30—0.22=-29.68° C.

It means this -29.68° C heat increases in the atmosphere.

Present highest temperature recorded at summer season in Bangladesh 43° C.

That means temperature should be 43°+-29.68°=14°C.

The percentage of climate change is 14/43X100=32.55%
