Disclaimer: Copyright infringement not intended.

Context

• The report, published by the UN’s World Meteorological Organization (WMO), said the years between 2015-2022 were the warmest on record.

Findings of the report

• The La Nina cooling weather phenomenon failed to ease the temperature hikes, with the past eight years considered the highest mean temperatures on record.
• In 2021, greenhouse gas concentrations peaked.
  • Carbon dioxide (CO2) concentration was at 415.7 parts per million globally, which is 149% of the pre-industrial level.
  • Methane meanwhile stood at 262% and nitrous oxide at 124%.
• Oceans were meanwhile the warmest on record.
  • Some 58% of ocean surfaces experienced a marine heatwave.
  • Around 90% of the energy trapped in the climate system by greenhouse gases goes into the ocean, somewhat ameliorating even higher temperature increases but posing risks to marine ecosystems.
