U.N. Secretary-general António Guterres said  July 2023 is the hottest month ever recorded. Talking to reporter  Mr. Guterres said the era of global boiling has arrived. So hot has the month been to date that researchers are confident the 2019 record will be broken, even with several days to go.

The U.N. World Meteorological Organization (WMO) and European Union's Copernicus Climate Change Service also said in a joint statement it was extremely likely July 2023 would break the record.  George Adamson, Reader in Climate and Society, King’s College London and author of ‘El Niño in World History’ said, “El Niño can cause major changes to weather patterns around the world although this can be highly disruptive. During El Niño events, more energy is released from the oceans to the atmosphere, which means that overall global surface temperatures will increase. 

Secretory General of the World Meteorological  Organisation Petteri Taalas said in a statement that the need to reduce greenhouse gas emission is more urgent than ever before.
The effects of July's heat have been seen across the world. Thousands of tourists fled wildfires on the Greek island of Rhodes, and many more suffered baking heat across the U.S. Southwest. Temperatures in a northwest China township soared as high as 52.2C (126F), breaking the national record.Scientists agree the extra heat is mainly linked to fossil fuel use.
