The Earth has been experiencing a steady rise in temperature over the past eight years, which has been recorded as the warmest on record globally. This trend is driven by an increase in greenhouse gas concentrations and accumulated heat. The World Meteorological Organization (WMO) has compiled data from six major worldwide temperature datasets to confirm this.
Record-breaking Temperature
The worldwide temperature in 2022 was approximately 1.15 [1.02 to 1.27] °C above pre-industrial levels, on average. The WMO has confirmed that 2022 was the eighth year in a row where annual global temperatures were at least 1°C higher than pre-industrial levels. This trend has led to the eight hottest years on record occurring between 2015 to 2022.
Growing Concerns
This steady rise in temperature has raised concerns about the possibility of temporarily exceeding the 1.5°C limit set forth in the Paris Agreement. The WMO warns that urgent action is required to reduce greenhouse gas emissions and curb global warming to prevent further damage to the Earth’s ecosystem.
Long-term Warming
The 10-year average temperature for the years 2013 to 2022 is 1.14 [1.02 to 1.27] °C higher than the pre-industrial average of the years 1850 to 1900. This confirms that long-term warming is still occurring, as estimated by the Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment report’s estimate of 1.09°C from 2011 to 2020.

Conclusion, the Earth’s record-breaking heat over the past eight years is a concerning trend that demands immediate action. The WMO’s data confirms that reducing greenhouse gas emissions is essential to curb global warming and prevent further damage to the planet’s ecosystem.
