AMOC: Is Global Warming Tipping Key Atlantic Ocean Currents Towards ‘Collapse’?
The Atlantic Meridional Overturning Circulation (AMOC) moves warm tropical water north and returns cold water south, keeping Europe milder and shaping global rainfall. Climate‑driven warming, ice melt, and freshening of the North Atlantic are weakening the system, prompting fears of a tipping point. The IPCC forecasts a steady decline through the 21st century but deems a full collapse before 2100 unlikely. Some researchers, however, argue that accelerating changes could push the AMOC into a centuries‑long weak state.
CCC: Net-Zero Will Protect UK From Fossil-Fuel Price Shocks
The Climate Change Committee’s new analysis shows that the UK’s net‑zero transition will generate average annual benefits of £110 billion between 2025 and 2050, outweighing its costs by 2029. A single fossil‑fuel price shock would cost the nation more than the...
Heatwaves Driving Recent ‘Surge’ in Compound Drought and Heat Extremes
A new study in Science Advances shows compound drought‑heat events have surged globally since the early 2000s, driven mainly by heatwave‑led events that more than doubled in area. The increase outpaces what can be explained by global warming alone, reflecting...
DeBriefed 6 March 2026: Iran Energy Crisis | China Climate Plan | Bristol’s ‘Pioneering’ Wind Turbine
The recent US‑Israeli strikes on Iran and Iran’s retaliatory attacks have halted shipping through the Strait of Hormuz, cutting roughly 20% of global oil flow and sending diesel and gas prices sharply higher in Europe and the United States. The...
Analysis: UK Emissions Fall 2.4% in 2025 as Coal Hits 400-Year Low
UK greenhouse gas emissions fell 2.4% in 2025 to 364 MtCO2e, the lowest level since 1872 and 54% below 1990. The decline was driven by coal use dropping to a 400‑year low and gas use reaching its lowest since 1992, both...
