A new United Nations report says greenhouse gases in the atmosphere have reached a record high.

According to the World Meteorological Organization's annual Greenhouse Gas Bulletin, the concentration of carbon dioxide was 149% higher in 2020 than before widespread industrialization.

The last time CO2 levels were this high was three-to-five million years ago when it was up to 3 Celsius degrees warmer and water levels were up to 20 meters higher.

The current trend puts us on a road to far exceed the 1.5 to 2 degrees Celsius temperature increase limit set by the Paris agreement.

The report found that while the Covid-19 pandemic resulted in a temporary decline in new emissions, it did not impact the amount of greenhouse gases already in the atmosphere.

That number is continuing to increase.

The findings come less than a week ahead of the COP26 climate talks scheduled to begin Sunday in Glasgow, Scotland.
