The week of 3-9 July 2023 was the warmest week ever measured globally, announced Monday the UN Meteorological Organization, after several daily temperature records were broken.

"The world has just experienced the warmest week on record, according to preliminary data," said the World Meteorological Organization (WMO) in a press release, after an already record month of June due to the combination of climate change caused by human activity with the first effects of the return of the maritime phenomenon El Nino.

Temperatures are breaking records both on land and in the oceans, 'with potentially devastating effects on ecosystems and the environment,' said the WMO.

'We are in uncharted territory and we can expect further records to fall as the El Niño phenomenon develops and its effects are felt until 2024,' said Christopher Hewitt, WMO Director of Climate Services.

El Niño is a natural climate phenomenon associated with warming ocean surface temperatures in the central and eastern tropical Pacific Ocean. The current episode will likely continue with "at least moderate intensity", according to the WMO.
