Climate scientists indicate global warming rate may be accelerating
BBC News reports that declining aerosol pollution and rising energy imbalances could lead to higher global warming projections.
The short version
- Researchers indicate that the pace of global warming has accelerated, partly as reductions in reflective sulphur pollution unmask further heat.[BBC News]
- Declining aerosols add an estimated 0.05C to 0.1C of warming per decade alongside roughly 0.2C from greenhouse gases, according to Prof Piers Forster.[BBC News]
- Analysis from ETH Zurich suggests emissions could produce about 25% more warming than earlier estimates, potentially raising projected century-end warming to near 3.5C.[BBC News]
Key facts
- Sulphur pollution particles reflect sunlight, partially offsetting carbon-driven warming.[BBC News]
- Earth's energy imbalance has roughly tripled across the past two decades, according to researcher Reto Knutti.[BBC News]
- Oceans warmed more than twice as fast over the past two decades compared to the 1960 to 2005 period, according to the World Meteorological Organization.[BBC News]
- The Met Office projects that 2027 is very likely to surpass 2024 as the warmest year on record.[BBC News]
What remains uncertain
- Whether revised climate sensitivity estimates will be confirmed remains uncertain, with long-term warming under current policies potentially reaching 3.5C if the models prove correct.[BBC News]
