- UN Environment Programme released an emissions gap report finding the world must cut greenhouse gases 18% by 2030 and 45% by 2045 to have a good chance of limiting warming to 1.7°C above preindustrial levels.
- Unep executive director Inger Andersen declared the "window has closed" on holding warming to 1.5°C, saying the world "procrastinated," though she urged countries to keep the Paris Agreement goal to make any overshoot "as brief and as short as possible."
- Under Donald Trump, the US — the world's second-biggest emitter after China — has withdrawn from the Paris Agreement and is threatening to reverse its long-standing trend of falling emissions, while pledges made at last November's Cop30 summit in Brazil were "noticeably weak."
- Even if all updated Cop30 pledges were fulfilled, temperatures would still reach 2.6°C above preindustrial levels; on current policies globally, 2.8°C — and every five years of emissions at current levels adds 0.1°C to forecasts, Unep found.
- Climate Analytics chief Bill Hare singled out the US and Saudi Arabia, which together produce 20–25% of global fossil fuels, for "looking at the fire, denying it exists and pouring more petrol on it."
- The Paris Agreement's next global stocktake in 2028 has been thrown into doubt because the IPCC failed to set a timetable to publish its latest report before governments assess their progress against the latest science.
- Johan Rockström of the Potsdam Institute projected global emissions will reach ~50 gigatonnes of CO2 equivalent annually by 2035 when they should be below 35 gigatonnes, calling the gap "a question of political action, not a lack of scientific evidence."
Why it matters: With the US having exited the Paris agreement and current national pledges pointing to 2.6–2.8°C of warming, the diplomatic and fiscal burden of curbing emissions now falls on the remaining major emitters and on a post-Trump political cycle. The next formal reckoning — the 2028 global stocktake — may arrive without a fresh IPCC report to underwrite it, weakening the scientific basis governments use to justify tougher near-term cuts.
