Greenhouse Gases, Other Climate Change Indicators Hit Record High in 2021 – WMO

Geneva – Human activities harmful to the environment have resulted in four main climate change indicators, including greenhouse gas and sea level, reaching record high in 2021, according to the World Meteorological Organization (WMO) report released on Wednesday.

“Four key climate change indicators – greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification – set new records in 2021. This is yet another clear sign that human activities are causing planetary scale changes on land, in the ocean, and in the atmosphere, with harmful and long-lasting ramifications for sustainable development and ecosystems,” the WMO said in its annual State of the Global Climate Report.

The organization added that the past seven years had been the warmest years in recorded history. In particular, the 2021 average global temperature was around 1.11 degrees Celsius (1.98 degrees Fahrenheit) above the pre-industrial level.

Such extreme weather conditions undermined food and water security in many regions of the world and led to economic losses worth billions of dollars, which put a heavy burden on the population, the WMO stressed.
