What is climate change? A simple guide

-


The United Nations Climate Change Conference 2021 (COP26) will kick off in Glasgow, Scotland, where representatives and heads of state from 200 countries will announce what steps will be taken in 2030 to unite the planet. Protection from the effects of climate change

Climate change is causing global warming to rise, and scientists have warned that urgent action is needed to protect the planet from the ravages of climate change.

We also need to know what climate change is and how it affects our environment.

Man-made products have increased carbon dioxide emissions, which increase the temperature.

Severe weather conditions and possible melting of mountain ice caps are among the possible effects.

What is climate change? 

A local climate is a measure of its seasons for many years. Climate change is a change in this scale.

Now the earth is facing a rapid climate change and global temperatures are rising.

What does climate change mean? 

Climate change will change our way of life, leading to water shortages and food insecurity.

Some regions can be dangerously hot and some will not be inhabited due to rising sea levels.

Extreme weather events such as heat waves, rain and storms will recur and intensify, threatening people's lives and livelihoods.

Residents of poor countries are less likely to adapt, so they will suffer more.

Climate 

The ice in the southern hemisphere and glaciers are melting rapidly. There is a risk of flooding in low-lying coastal areas and oceans.

When glaciers melt in areas such as Siberia, methane, a greenhouse gas, is released into the atmosphere, exacerbating the effects of climate change.

Climatic conditions are increasing.

Nature 

As their habitat changes, some species will migrate to new areas.

But climate change is so rapid that many species are at risk of extinction.

White bears are in danger of disappearing because the ice they rely on melts quickly.

Atlantic salmon can be wiped out as the breeding grounds warm up.

Coral reefs may disappear as the acid in the sea rises due to the absorption of excess carbon dioxide.

What are the reasons?

There have been natural changes in the climate.

But as a result of human activity, global temperatures are now rising.

The earth has been warmed by about 1.2 degrees Celsius in the past since humans started using oil, gas and coal. Gasoline is used to generate industry, transportation and heating.

Burning these minerals releases greenhouse gases that trap solar energy.


The amount of carbon dioxide, greenhousle gases, has increased by about 50 percent since the 19th century and 12 percent over the past two decades.

Deforestation is another reason for the increase in greenhouse gases.

When trees are burned or cut down, they usually retain carbon and release it.

What will happen in the future? 

Scientists have set a temperature of 1.5 degrees Celsius as the "safe" limit for global warming.

If the temperature rises, harmful changes in the environment may change the way people live.

Many scientists believe that this will happen and have predicted an increase of three degrees Celsius or higher by the end of this century.

It will have different results worldwide

The UK will be at risk of flooding due to heavy rains

Countries with low Pacific islands may become overwhelmed by rising sea levels.

Many African countries will suffer from drought and food shortages

A severe drought in North America will affect the western part, and some areas are likely to experience more rainfall and severe storms.

Australia is likely to experience severe heat and severe drought

What are governments doing? 

Countries around the world are being asked to set targets that will reduce their greenhouse gas emissions to “zero” by the middle of this century.

This means that any gas emissions will be measured by absorbing equal amounts, for example by planting trees.

The hope is that it will counteract the devastating effects of climate change by halting global warming.

What are scientists doing?

Scientists' knowledge of climate change is constantly growing.

For example, they can now see the link between climate change and a single seasonal event such as heavy rain and heat waves.

It is hoped that they will be able to better predict such future catastrophes.

What can people do?

Scientists say that humans can do the following:

Reduce reliance on cars by using public transport or bicycles on the go

* Fill in your homes

* Reduce flight

* Reduce consumption of meat and milk

An art graduate whose creative power was no less than that of a scientist Ibn Safi holds a unique place among Urdu writers. In the beginning, the critics of literature did not consider him worthy of attention, but then all became captives of his pen. Ibn Safi's pen journey spans 28 years . During this journey, he created about two and a half hundred novels which were published under the name of Jasusy Dunia (Detective World) and Imran Series. In January 1952, the world's first detective novel, Dalair Mujram(The Brave Criminal) , was published, and in August 1955, the first novel in the Imran series, Khaofnak Amarat (The Terrible Building), was published. This continued until his death. In these novels, he invented a new world in which crime was eliminated with the help of new methods and inventions. Irfan Javed , a well-known author on science fiction, writes in his book Ajaib Khana'(Museum )' that 'surprisingly many novels and fictions in the West have led to sci...

13 years of Lal Masjid operation

  The motives of the military operation on Lal Masjid in Islamabad and the vague facts related to it Thirteen years have passed since the military operation on the Lal Masjid in Islamabad in 2007, but even today the issue is not fully resolved. Even nowadays the smoke sometimes erupts, which can be a precursor to a major accident at any time. Various reasons are given for this operation. Some people speak in favor of the operation, while others complain of resolving the issue without any disciplinary action. What were the motives for this military operation? To make the capital 'free from obscenity' In May and June 2007, students from various madrassas run by the Lal Masjid administration were active in promoting Islam, establishing an Islamic system in the country and "cleansing" the federal capital. They would sometimes set fire to CDs in video and CD shops and sometimes break into massage centers in different sectors of the city without permission, not only torturi...

  50 years of Bangladesh's existence: Language, cultural domination, disenfranchisement or any conspiracy, what were the driving forces behind East Pakistan becoming Bangladesh?  When Indian Prime Minister Narendra Modi visited Dhaka on the occasion of Bangladesh National Day in March this year, the two countries, along with their counterpart Hasina Wajid, agreed to make December 6 the 'Day of Friendship'. Will celebrate One has to go back 50 years to know the significance of this history, when on December 6, 1971, India recognized Bangladesh as an independent country when it was the eastern part of Pakistan. Just ten days later, Lieutenant General Amir Abdullah Khan Niazi, commander of the Pakistan Army in East Pakistan, signed a surrender document with Indian Army Lieutenant General Jagjit Singh Arora and conceded defeat. Emerged as a state on the world map. It would not be wrong to say that Bangladesh has the closest ties with India among the South Asian countries. At th...
