The World Meteorological Organization said in a new report today, Wednesday, issued in Geneva that four main indicators of climate change, including concentrations of greenhouse gases, sea-level rise, ocean temperature, and ocean acidification, have set new records in 2021, confirming that human activities are causing Changes in the planetary scale on land, in the ocean and in the atmosphere, with harmful and long-term implications for sustainable development and ecosystems.

The report indicated that severe weather (the daily face of climate change) led to economic losses estimated at hundreds of billions of dollars, caused huge losses in human lives and well-being, and caused shocks to food and water security and displacement that emerged in 2022, and that the past seven years were the seven warmest Recorded years and that 2021 was only one among the seven warmest, and that the average global temperature in 2021 was about 1.11 (± 0.13) degrees Celsius above the pre-industrial level.

In a message coinciding with the launch of the report today, United Nations Secretary-General Antonio Guterres said that five critical actions are needed to start the transition to renewable energy, including increasing access to renewable energy technology and supplies, tripling private and public investment in renewable energy sources, and ending subsidies on renewable energy. Fossil fuels are about $11 million per minute.

Guterres added in his message that renewable energy is the only way to real energy security, stable energy prices, and sustainable job opportunities and that the transformation of renewable energy can be the peace project of the twenty-first century, calling on the world to move in this decade to prevent the ever-worsening climate impacts and to preserve The temperature rise is less than 1.5°C above pre-industrial levels.

For his part, Petteri Taalas, Secretary-General of the World Meteorological Organization, warned that the heat entrapped by human-caused greenhouse gases will warm the planet for many generations to come, as sea levels will rise and the oceans will heat and acidify for hundreds of years unless methods are invented to remove carbon from the atmosphere.

Talas stressed that some glaciers have reached a point of no return, and this will have long-term repercussions, in a world where more than two billion people are already water-stressed.

It is noteworthy that the report on the state of the global climate issued today, which will be used as an official document, for the United Nations negotiations on climate change known as (COP27) to be held in Sharm El-Sheikh, Egypt next November, is a supplementary report to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change.

The report pointed out that the last seven years from 2015 to 2021 were the seven warmest years on record, and warned that the ocean temperature was a record high and that the ocean depth of 2000 meters, continued to rise in 2021 and is expected to continue warming in the future.

The report pointed to the seriousness of the phenomenon of ocean acidification, as the ocean absorbs about 23% of the annual emissions of human carbon dioxide, originating in the atmosphere where this interacts with seawater, and leads to ocean acidification, which threatens living organisms and ecosystem services, and thus food security, tourism, and coastal protection.

The report noted that the global average sea level reached a new record level in 2021, after rising by an average of 4.5 mm annually during the period 2013-2021, which is more than double the rate between 1993 and 2002, due to the accelerated loss of ice mass from the plates. icy glaciers, warning that the phenomenon has significant effects on hundreds of millions of coastal residents and increases vulnerability to tropical cyclones.

The report said that the complex effects of conflicts and extreme weather events, in addition to the economic shocks exacerbated by the Corona epidemic, have undermined decades of progress towards improving food security globally, while the exacerbation of humanitarian crises in 2021 led to an increasing number of countries at risk of starvation. .

He pointed out that of the total number of undernourished people in 2020, more than half of them live in Asia (418 million) and a third in Africa 282 million.

The report stated that hydrometeorological hazards continued to contribute to internal displacement and that the countries that recorded the largest number of displacements as of October 2021 were China (more than 1.4 million), the Philippines (more than 386,000 people) and Vietnam (more than 664,000 )
