Israt Jahan: Climate change is not a common occurrence. Climate change is one of the most talked-about and critical events in the world. Global warming is increasing day by day due to this climate change. The rate at which global warming is increasing is a threat to the world. The problem of climate change and climate change is now presented to the people of the world as a recognized fact. They have been thinking about it for many years now when global change has caught the attention of world leaders. It is not a change that happened a few years or a few decades ago, it happened about one hundred to one hundred and fifty years ago. According to the graph of global temperature that we see in various scientific research papers, "the average temperature has risen close to one degree in the last 100-150 years." A review of the current state of the earth shows how much it has become a threat to living and inanimate objects.

Ever since climate change began to take a deadly turn, environmentalists and world leaders have been fearful that if the temperature could change from one degree to four to five degrees, every animal and every object will fall into the lap of death. The reason for this line of thinking and fear is that the higher the temperature, the more unbearable the weather will become and the more uncertainty will be. Environmentalists and world leaders then decide that the temperature should not be allowed to rise more than two degrees. The Paris Agreement was originally signed in 2015 to prevent further growth.

Scientists have been expressing different views and fears about climate change for so long. And the fact that their fears are slowly becoming a reality can be inferred from the current weather conditions. The effects of climate change are being noticed in more or less every country in the world. Somewhere floods caused by heavy rains, somewhere or lives of people suffering from drought, somewhere fires caused by intense heat. The amount of water on the surface of the sea is increasing due to the melting of polar ice. And so the lowlands are at risk. On August 9, the United Nations released a report on climate change. The report is no ordinary report.  This is the biggest report so far.  The 42-page report has been described as a "red signal for humanity."

The report is based on thousands of studies conducted by the United Nations to provide details on climate change. This report was prepared by the Intergovernmental Panel on Climate Change (IPCC) of the United Nations. The IPCC is a special branch of the United Nations on climate change formed by the governments of different countries. Based on more than 14,000 scientific studies, the report provides the most detailed and detailed picture of how climate change is changing the natural environment and what could happen next.

The report said, "Over the next two decades, the world`s average temperature will rise by 1.5 degrees Celsius above pre-industrial temperatures. Besides, by the end of this century, the sea level will rise by 2 meters. In the past, the heatwave that used to swell in different parts of the world every 50 years is now happening every year. So many fears about climate change are true. All the predictions and concerns that scientists have been making for so long are going to happen. In addition, evidence has been found that humans have direct responsibility for the unprecedented changes in the world`s climate. However, future losses can still be prevented. To avoid the risk, greenhouse gas emissions must be drastically reduced within a decade."

UN Secretary-General Antonio Guterres called the report a `red signal for humanity.` "We have no time to be late. There is no room for excuses. We trust the governments and partners of all countries to make the Glasgow Climate Conference a success," he said. A UN conference on climate change will be held in November this year in Glasgow, Scotland. The report was published three months before the conference.

Developed countries are most responsible for climate change. They do not have time to look at the environment that has been adversely affected by the addiction to development and the devastating effects that this addiction has had on underdeveloped and developing countries. Due to their indifference, the lives of the people in these countries are becoming more and more uncertain. On April 22 this year, a two-day `Leaders Summit` was inaugurated at the invitation of US President Joe Biden to address the challenges of climate change. The inaugural session was attended by 41 world leaders including Bangladesh. The United Nations has previously issued a "Red Alert" on climate change and the future of the planet. "The Blue Planet (Earth) is now in a major crisis. Risks have been created in many ways, and we are responsible for that," said the report`s creator in the latest IPS climate report.

The world needs to be more aware of climate change as soon as possible otherwise it will become more of a threat to the world. It will push the people of many countries to the brink of death. Therefore, every developed, underdeveloped, and developing country must work together to overcome the indifferent attitude in this regard.
