The target of keeping long-term global warming within 1.5 degrees Celsius is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea.

Though mean temperatures had temporarily breached the 1.5 C threshold before, this was the first time they had done so in the Northern Hemisphere summer that starts on June 1. Sea temperatures also broke April and May records.
