Climate Change: Greenhouse gas, sea level rise set new records in 2021

Greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification — the four key climate change indicators — set new records in 2021 with extreme weather — the day-to-day ‘face’ of climate change — led to hundreds of billions of dollars in economic losses, the WMO State of the Global Climate in 2021 report said on Wednesday.

“It wreaked a heavy toll on human lives and well-being and triggered shocks for food and water security and displacement that have accentuated in 2022. 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 World Meteorological Organisation (WMO) said.
