A new report from the European Union's Copernicus Climate Change Service shows that the global average temperature from January to October of this year is the highest ever recorded, dangerously close to the 1.5 degree Celsius warming threshold. October was 0.4 degrees Celsius (0.7 degrees Fahrenheit) warmer than the previous record for the month in 2019, and it is virtually certain that 2023 will be the hottest year on record. This could bring about significant challenges for people worldwide, so it is important that governments and citizens take action to reduce emissions and mitigate the effects of climate change.
