The results of various scientific studies on the repercussions of climate change and its catastrophic effects on nature and humans show that the world is on the verge of worse in the coming years and decades.
In one of the most recent studies, it concluded that global warming will expose more than a fifth of humanity to extreme heat, which may threaten life, by the end of this century.
Global warming constitutes a global concern that haunts the countries of the globe. Its effects have increased, and its economic cost has become a phenomenon more than ever before. As for its human bill, it is rising, and threatens a catastrophe that befalls hundreds of millions of people around the world.
What does the study say?
The study, published in the journal Nature Persistence, revealed that global surface temperatures are set to rise by 2.7 degrees Celsius by the year 2100, compared to the pre-industrial era.
By this date, two billion people will suffer from global warming, which will keep them away from the comfortable climatic conditions that allowed humanity to develop over thousands of years.
most affected countries
The study warned that certain countries are facing a catastrophic fate represented by deadly heat waves, such as India, Nigeria, Indonesia, the Philippines and Pakistan, noting that the risks are increasing in regions along the equator.
While the climate could become deadly there if temperatures rise, due to moisture that prevents the human body from cooling itself, and in the worst-case scenario, with climate sensitivity to greenhouse gases higher than expected, the global temperature will rise by 3.6 degrees Celsius and leave nearly half of The world’s population is outside of a suitable climate environment.
Experts warn that the worst is yet to come, and that the record high temperatures will affect hundreds of millions of people with deadly repercussions and turn large parts of the earth into uninhabitable areas, which requires urgent international action to remedy the disaster afflicting the earth and its inhabitants.
Rising temperatures due to greenhouse gas emissions
The world is on the brink
Ayman Haitham Qaddouri, an environmental expert and member of the International Union for Conservation of Nature, said in an interview with Sky News Arabia:
* Global warming is the focus of climate change research operations. The continuous rise in temperatures over the past two decades and their breaking of global determinants in more than a year has directed scientific efforts to study the effects of this rise.
* The Intergovernmental Panel on Climate Change (IPCC) stated in its report published in 2019 that the world is on the cusp of exceeding 1.5 degrees Celsius, the limit set by the Paris Agreement in 2015, for a rise in average temperature by the global warming limit in 2050.
* It is possible that this rate will rise by the end of the century, that is, in the year 2100, to reach more than 2 degrees Celsius, which threatens the stability of 70% of people through the exacerbation of the consequences of the climate change process, from severe droughts on the one hand and torrential floods on the other hand, the scarcity of fresh water and the lack of The ability of humans to provide the most important elements of life, displacement from areas that the high temperature will make unsuitable for human settlement towards somewhat cooler areas on the surface of the planet.
* The study, which was published within the journal Nature Sustainability, which keeps pace with the climatic events of recent years, and confirms the findings of the studies of the Intergovernmental Panel on Climate Change (IPCC), adding that exceeding the threshold of 1.5 degrees Celsius has become a reality, and the world is heading to reach 2.7 degrees Celsius at the end of the century.
* Thus, more than one-fifth of the world’s population will be exposed to extremely dangerous temperatures that discourage human activity, with fatal health effects that lead to death, in addition to the damages resulting from the exacerbation of the climate change process and the succession of natural disasters and their recurrence at an escalating pace.
Meteorological Organization: High temperatures in the next 5 years
How can the world avoid or reduce the effects of global warming?
* Predictions indicate an increase in the average annual temperature from 13-25 degrees Celsius, the optimum temperature for humans, to reach 29 degrees Celsius, which means a shrinking of the human climate suitable for habitation and the exercise of human activities, which puts two billion people at risk, and for this what is required:
* Intensifying global efforts to limit global warming and returning to the 1.5°C threshold approved by the Paris Climate Agreement in 2015 is the only way to spare three quarters of the world’s population from exposure to unprecedented temperatures that are not recorded in the records of the climatic regions distributed within the terrestrial climatic regions.
Fulfilling the Paris Climate Agreement requires the commitment of the major industrialized countries, led by the United States, China and India, to reduce greenhouse gas emissions resulting from excessive industrial activity, while activating the role of the “losses and damages” fund to support affected countries and address the effects of climate change in developing countries, especially those that are not It has actual contributions to the global warming process.
Importance of COP 28 Summit
* And the launch must be quick and immediate, with a time limit that does not exceed the date of the next climate summit, in the UAE, COP28, and for the upcoming summit to be a turning point towards a more stable climate for future generations.
