“The world just had the hottest week on record, according to preliminary data,” the WMO said in a statement, after climate change and the early stages of the El Nino weather pattern drove the warmest June on record.

“We are in uncharted territory, and we can expect more records to fall as El Nino develops further and these impacts will extend into 2024,” said Christopher Hewitt, WMO director of climate services.
