- Energy analysts report renewables became the largest power source in 2025, with wind and solar exceeding demand growth and coal output edging lower.
- Scientific records show a sharp temperature jump since 2015 and escalating extremes, alongside reports of a tipping signal with widespread coral reef decline.
- Progress in clean technology has lowered projected end‑century warming to around 2.8°C, yet a UN assessment says current pledges miss Paris‑level cuts by a wide margin.
- Political headwinds weigh on the talks as the United States under President Trump rolls back clean‑energy incentives and advances fossil fuel expansion.
