The 27th session of the Conference of the Parties (COP27) to the United Nations Framework Convention on Climate Change (UNFCCC) started Sunday in the Egyptian coastal city of Sharm El-Sheikh, with countries jointly seeking to combat the global climate crisis.

In the past year, in addition to climate change and the lingering impact of the COVID-19 pandemic, the world has been battered by multiple crises such as geopolitical conflicts, higher energy and food prices, increasing inflation, and frequent extreme weather events.

Under such circumstances, the convening of the climate conference appears all the more important. Collective, complementary and collaborative actions by countries around the world to adapt to the effects of climate change, mitigate its negative repercussions, and provide climate finance have become the focus of this year's conference agenda.

URGENT NEED FOR CLIMATE ACTIONS

Since the beginning of 2022, heatwaves, torrential rains, floods, droughts and other natural disasters occurred one after another around the world. Europe has experienced unprecedented high temperatures and heatwaves not seen in centuries, as well as frequent droughts and wildfires. One third of Pakistan has been completely submerged by historic flooding. Powerful hurricanes have made thousands of families homeless in the U.S.

Yet, Robert Stefanski, the World Meteorological Organization's chief of Applied Climate Services, said 2022 may be the year with the best climate from now on. He warned that if the world does not take urgent actions, extreme weather events such as heatwaves, droughts and floods may become the "new norm" in the world.

Should global warming reach 3 degrees Celcius by 2100, according to a UN report, drought losses could be five times higher than they are today, with the largest increase in the Mediterranean and the Atlantic regions of Europe.

The UN Food and Agriculture Organization (FAO) estimates that by 2030 Africa will lose two-thirds of its arable land if the march of desertification -- the spread of arid, desert-like areas of land -- is not stopped. Since the beginning of this year, many African countries are facing the risk of food shortages or supply interruption, even in countries with rich water resources.

The loss and damage caused by global climate change have become one of the top issues, said Egypt's chief climate negotiator Ambassador Mohamed Nasr, adding that "the international response is still not up to the challenge of the impacts."

COP27 will hold a round table summit on climate change and food security, during which initiatives on agriculture, food security and nutrition will be proposed, and agricultural solutions under climate change will be a priority in multilateral negotiations.

"We have witnessed during this year painful events in Pakistan, the African continent and various parts of Europe and America. All these events and the destruction and impact represent a lesson to be learned and alarm all over the planet... to more precaution, and to act quickly to take all necessary measures as per our commitments and pledges," Egyptian Foreign Minister and COP27 President Sameh Shoukry said at the COP27 opening ceremony.

"Dealing with climate change problems is obligatory, not a choice," said Egyptian climate and environment expert Magdy Allam. Under the slogan of COP27 -- Together for implementation -- the host country Egypt calls on countries across the globe to convert their previous commitments on climate change from lip service to action, he said.
