2027: Will El Niño Trigger Hottest Year Ever?
6 Nov
Summary
- El Niño may drive 2027 to become the hottest year on record.
- Europe's October temperatures already exceeded 2023 records.
- Academics urge Australia to accelerate climate action now.
Global temperatures are projected to reach a historic peak in 2027, influenced by an unprecedented El Niño event amplifying climate change-driven warmth. Climate researcher Zeke Hausfather forecasts a potential rise of 1.8 degrees Celsius above preindustrial levels.
Recent data from Europe's ERA5 dataset indicates October temperatures already exceeded previous records, reaching 1.75 degrees Celsius above preindustrial averages. Projections suggest 2026 will be the second-hottest year on record, just below 2024.
This outlook coincides with an open letter from over 500 academics, including prominent Australian scientists, urging national leaders to accelerate climate action. They call for an end to approvals for new fossil fuel projects and demand a legally binding fossil fuel phase-out timetable.
The academics emphasize Australia's potential to lead globally, particularly as it prepares to host COP31. They implore leaders to act with courage and urgency, highlighting the mounting climate impacts associated with continued support for fossil fuel expansion.
