First June breach of 1.5°C limit

Copernicus records first June breach of 1.5°C climate threshold

The global-mean surface air temperature was more than 1.5°C above pre-industrial levels in early June, which is a first for a summer month, the EU-funded Copernicus Climate Change Service (C3S) implemented by ECMWF has said.
Sea-surface temperature analysis 1-8 June 2023

Forecasts show growing El Niño event

Forecasts assembled by the EU’s Copernicus Climate Change Service implemented by ECMWF predict a growing El Niño event, which is a prolonged period of abnormally high sea-surface temperatures in the tropical Pacific Ocean.

2 m temperature forecast for Paris on 17 June 2022 22 UTC

Developing an urban scheme for the IFS

The urban environment will for the first time be considered in ECMWF’s Integrated Forecasting System (IFS) from next year. This is important because in cities temperatures are often elevated compared to their surroundings.
