Mar 24th 2026 · World
A WMO report shows 2015–2025 as the warmest 11-year stretch on record, with Earth absorbing more energy than it radiates and 2024 CO2 at a two million year high; other research highlights include bioengineered oesophagi that restored swallowing in pigs and progress toward a thorium nuclear clock.
- 2015–2025 are the 11 hottest years on record, according to the World Meteorological Organization.
- Earth's energy imbalance is at its highest level since observations began in 1960.
- Atmospheric carbon dioxide in 2024 reached concentrations not seen in two million years.
- Lab-grown oesophagus segments were transplanted into pigs and restored swallowing, pointing to potential human treatments.
- Physicists expect the first measurements from a thorium-229 nuclear clock as components and a driving laser near readiness in 2026.
