WMO Releases ‘tell-tale Signs’ Of Extreme Weather Conditions Around The World
From extreme floods to heat and drought, weather and climate-related disasters have affected millions and cost billions this year, the World Meteorological Organization (WMO) said on Friday, describing the “tell-tale signs and impacts” of intensified climate change said WMO chief Petteri Taalas.
While Global temperature figures for 2022 will be released in mid-January, the past eight years are on track to be the eight warmest on record, according to WMO.
While the persistence of a cooling La Niña event, now in its third year, means that 2022 will not be the warmest year on record, its cooling impact will be short-lived and not reverse the long-term warming trend caused by record levels of heat-trapping greenhouse gases in our atmosphere.
Moreover, this will be the tenth successive year that temperatures have reached at least 1°C above pre-industrial levels. Early warnings, increasing investment in the basic global observing system and building resilience to extreme weather and climate will be among WMO priorities in 2023 – the year that the WMO community celebrates its 150th anniversary. WMO will also promote a new way of monitoring the sinks and sources of carbon dioxide, methane and nitrous oxide by using the ground-based Global Atmosphere Watch, satellite and assimilation modelling, which allows better understanding of how key greenhouse gases behave in the atmosphere.
In East Africa, rainfall has been below average throughout four consecutive wet seasons – the longest in 40 years – triggering a major humanitarian crisis affecting millions of people, devastating agriculture, and killing livestock, especially in Ethiopia, Kenya and Somalia.
Record breaking rain in July and August led to extensive flooding in Pakistan, which caused at least 1,700 deaths, displaced 7.9 million and affected 33 million people.
“One third of Pakistan was flooded, with major economic losses and human casualties”, reminded Mr. Taalas.
