The concentration of planet-heating pollutants clogging the atmosphere hit record levels in 2023, the World Meteorological Organization (WMO) said on Monday, October 28.
Despite climate change warnings issued by the Intergovernmental Panel on Climate Change (IPCC) since 1990, global emissions have continued to rise in the last decade, reaching their highest point in history.
The result: global emissions are on track to blow past the 1.5 degrees C warming limit envisioned in the 2015 Paris Agreement.

The target of keeping long-term global warming within 1.5 degrees Celsius (2.7 Fahrenheit) 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.
Nearly half the world's population is considered highly vulnerable to the impacts of climate change -- floods, heat, drought, wildfires, and storms.
