The past eight years have been the hottest of those recorded so far, fueled by increasing concentrations of greenhouse gases and heat accumulating in the sea. The average temperature in 2022 is about 1.15 degrees above pre-industrial levels (i.e. the average temperature for the period 1850-1900). This was revealed by the report “The State of the Global Climate in 2022” issued by the World Meteorological Organization (Wmo), which was released today on the occasion of the opening of the United Nations Climate Conference COP27 in Sharm El-Sheikh, Egypt, where he was the Prime Minister. is expected Georgia Meloni The Minister of Environment Gilberto Piccito Fratine.
This increase in temperature is attributed to increased concentrations of major greenhouse gases in the atmosphere (carbon dioxide, methane and nitrogen dioxide). These gases reached record levels in 2021, and continue to rise in 2022. Heat is melting polar ice caps and glaciers, and causing sea level rise, threatening island nations and coastal lands.
Also, the reason Desertification and extreme weather eventsThousands of people were killed, millions were deprived of livelihoods, and they were condemned to starvation, poverty and emigration. Then heat and disasters cause a series of diseases to spread. “The greater the warming, the worse the effect – commented Wmo Secretary-General, Petteri Taalas – we have so high levels of carbon dioxide in the atmosphere today that the target of 1.5 degrees (of warming compared to pre-industrial, ed) from the Paris Agreement can hardly be achieved. to get it “. For Tlass, “It is already too late for many glaciers, and the melt will continue for hundreds if not thousands of years, with serious consequences for water security.”
An increase in sea levels of a few millimeters per year means an “increase from half a meter to one meter in a century, and this is a threat to millions of coastal and island dwellers.” “Those least responsible for climate change suffer the most – as we have seen with the terrible floods in Pakistan and the prolonged and deadly drought in the Horn of Africa. But well-prepared communities have also been affected by this year’s events. The extremes, as we have seen with heat waves and droughts in large parts from Europe and southern China.
Mwo’s report makes it clear as well Drought in 2022 starved 19 million people in East AfricaWhile the floods killed 1,700 people in Pakistan and forced nearly 8 million from their villages.
In East Africa, rainfall has been below average for four consecutive seasons, the longest in 40 years, and there are indications that the current season will also be dry. Between 18.4 and 19.3 million people were in a state of food crisis before June 2022 in Kenya, Somalia and Ethiopia. Record rains in July and August led to widespread flooding in Pakistan. There were at least 1,700 deaths and 33 million people affected. There were 7.9 million displaced people. South Africa, in particular MadagascarEarlier this year, it was hit by a series of hurricanes.
Hurricane Ian in September caused death and destruction in Cuba and in Florida. Much of the Northern Hemisphere has been exceptionally hot and dry this year. China has experienced the longest and longest heat wave in history, and the second dry summer on record. The Yangtze River in Wuhan reached an all-time low in August. Large areas of Europe experienced frequent bouts of extreme heat. On July 19 the United Kingdom set its national record, with a score of over 40 for the first time. And the heat of drought and fires. European rivers, including the Rhine, Loire and Danube, have fallen to critical levels.
Cop27 puts climate damage financing on the agenda
The issue of financing the damage already caused by climate change will be discussed at COP 27, according to the agenda approved at the opening of the World Climate Conference in Sharm El Sheikh, Egypt. Poor and vulnerable nations, which are little responsible for global warming but highly vulnerable to its consequences, insist that the issue of damage is officially on the agenda of the COP while rich nations have been very reluctant on the issue.
