These climate change-induced extreme events and disasters set new records, left millions of people affected, and cost billions. Although there were no new global temperature records, however, several national heat records were recorded in different parts of the world. Mapping annual temperature anomalies (1850 to 2022).

Specifically, Pakistan and India experienced a record-breaking heatwave in March and April. After heatwave, Pakistan experienced another extreme weather event, a mega-flood in August 2022. Pakistan Flood (August 2022) During July and August record-breaking rains were observed across Pakistan. At national scale rainfall was +243% above climatic average with significant spatial variation, highest for Sindh province (+726%) followed by Balochistan province (+590%) (WMO).

Flood also affected more than 48,000 km2 croplands, posing serious threats to regional food security. Credit : United Nations Satellite Centre (UNOSAT)

Europe European Heatwave 2022: Highest Temperature during heatwave: 47.0 °C (116.6 °F), recorded at Pinhao, Portugal (14 July 2022) (The Portugal News) Credit: NOAA Greenland: Late Season Melting
In September 2022 (1-6 September), a substantial ice melting event was recorded atop the Greenland ice sheet. Scientists warned about the implications of this extensive melting event. At its peak on July 18, surface melting spanned 688,000 square kilometers (266,000 square miles) of the ice sheet. A late-season warm spell (September 1–6 2022, with its peak on September 3), caused the melting of 592,000 square kilometers of the ice sheet.
