The planet is heating faster than models predicted, and the UK has summoned world leaders for an emergency climate summit in London next week. Global average temperatures are on track to surpass the previous record set in 2023, according to new data from the UK Met Office and NASA. The anomaly is driven by a combination of continued greenhouse gas emissions and a strengthening El Niño event in the Pacific, which is injecting additional heat into the atmosphere.
Dr James Hansen, the veteran climate scientist, said in a statement: 'We are moving into uncharted territory. The rate of warming in the last 12 months is unprecedented in the instrumental record.' The Met Office predicts a 60% chance that 2024 will be the hottest year ever measured.
The UK Prime Minister will host the summit at Lancaster House, with attendees including the heads of state from the G20 and vulnerable island nations. The agenda includes emergency measures such as temporary carbon taxes, accelerated deployment of solar and wind capacity, and a potential freeze on new oil and gas exploration licenses.
But the science is clear: even if emissions stopped tomorrow, the heat already locked into the ocean would continue to raise global temperatures for at least another decade. The ocean has absorbed 90% of the excess heat from global warming, and its thermal inertia means we are committed to further warming regardless of near-term action.
This is a moment of calm urgency. The window to limit warming to 1.5°C above pre-industrial levels is closing. We have perhaps five years at current emission rates before that target is breached permanently.
The summit is a start, but the real work begins when the cameras leave. Every fraction of a degree matters. Every tonne of carbon avoided reduces the risk of tipping points: the collapse of the Greenland ice sheet, the Amazon becoming a net carbon source, the permafrost thaw accelerating.
For now, the numbers speak. The planet is telling us, in the most direct physical language it can, that our systems are overdue for an overhaul. The UK summit must be the beginning of a new era of climate action, not another photo opportunity.
