July 2019 was the hottest month on record

• According to the report, July was around 0.56°C higher in temperature than the global average between 1981–2010, and close to 1.2°C above preindustrial levels. A landmark UN report released last year warned that global temperatures will only be held to 1.5°C above preindustrial levels — which could help to stave off some effects of global warming — only with "unprecedented" action around the world.

Of note: The C3S report further noted that "every month in 2019 has ranked among the four warmest for the month in question, and June was the warmest June ever recorded."
