United Nations report: The world faces a disaster this century Science

In a new report released by the United Nations Environment Program on November 20, the Panel of Experts on Climate Science declared that current measures taken by the world are not enough to prevent average global temperature increases of 1.5 degrees Celsius. degrees in the current century, it has become day by day, this century will end with a rise of 2.9 degrees Celsius.

This comes as the entire world is experiencing an alarming acceleration in the number, speed and scale of climate records. In 2023 alone, 86 days were 1.5°C warmer than the pre-industrial period. September was the hottest month on record.

These temperature rises, along with catastrophic extreme events, the Intergovernmental Panel on Climate Change warned, are “the beginning” of a major future disaster.

The following video shows where we are headed as emissions continue to rise and temperatures exceed expected limits:

What happens when the temperature rises by 2.9 degrees?

The average citizen thinks that if the average temperature rises by 2.9 degrees Celsius, the summer temperature will change from an average of 35 degrees to about 38 degrees, but this is completely wrong, because the increase in average temperature will cause absolute. Imbalance in Climate and Ecosystem.

For example, it will double the rates, intensity and duration of extreme weather events such as heat waves, droughts, floods, storms and wildfires, and global sea levels will rise by up to one meter by the end of the century, threatening coastal areas. cities.

Additionally, Earth will lose up to 40% of its Amazon rainforest, which traps more carbon dioxide in the atmosphere, affecting everything from coral reefs and fisheries to the rice and wheat we eat.

We are not talking about the dangers of water shortages, the spread of diseases, migration, internal and external conflicts, and what is worse, if the world crosses them, there are tipping points that will lead to disaster and irreversibility. Changes in the climate system, such as the melting of the ice sheets in Greenland and Antarctica and the disturbance of water currents in the oceans.

Report the results

The report found that global greenhouse gas emissions will increase by 1.2% from 2021 to 2022 to reach a new record of 57.4 gigatonnes of carbon dioxide.

Greenhouse gas emissions are expected to increase by 16% by 2030, although the path to the 2015 Paris Agreement was supposed to reduce carbon dioxide emissions into the atmosphere by 42%. degrees Celsius.

Halting a 1.5 degree rise in average temperatures is still possible, the report points out, but that would require uprooting fossil fuels, the main root of the climate crisis.

The report calls on all countries to accelerate development transitions towards a low-carbon economy, and high-emitting countries to take greater action and support developing countries in their efforts to avoid climate disasters they did not cause.
