Four key climate change indicators set new records in 2021@ “State of the Global Climate” report from the World Meteorological Organization (WMO)

Key climate change indicators like greenhouse gas concentrations, sea level rise, ocean heat content, and ocean acidification all hit new highs in 2021. According to the World Meteorological Organization, this is yet another clear indication that human activities are causing planetary-scale changes on land, in the ocean, and in the atmosphere, with long-lasting and harmful consequences for sustainable development and ecosystems.Hundreds of billions of dollars in economic losses and a heavy toll on human lives and well-being have been attributed to extreme weather. A latest report from the World Meteorological Organization confirms that the last seven years have been the warmest in recorded history. The average global temperature in 2021 was about 1.11 (± 0.13) °C above the pre-industrial level.

The WMO State of the Global Climate report is an addition to the IPCC’s Sixth Assessment report, which includes data up to 2019. For policymakers, the new WMO report includes a story map that shows how the climate change indicators outlined in IPCC reports have played out globally in recent years and how the associated implications on extremes have been felt at national and regional level in 2021. UN Climate Change Negotiations known as COP27 will take place in Egypt later this year, using the WMO State of the Global Climate report as an official document.
