Copernicus Climate Change Service says results a ‘large and continuing shift’ in the climate

The world has baked for 12 consecutive months in temperatures 1.5C (2.7F) greater than their average before the fossil fuel era, new data shows.

Temperatures between July 2023 and June 2024 were the highest on record, scientists found, creating a year-long stretch in which the Earth was 1.64C hotter than in preindustrial times.

The findings do not mean world leaders have already failed to honour their promises to stop the planet heating 1.5C by the end of the century – a target that is measured in decadal averages rather than single years – but that scorching heat will have exposed more people to violent weather. A sustained rise in temperatures above this level also increases the risk of uncertain but catastrophic tipping points.

    Copernicus, a scientific organisation that belongs to the EU’s space programme, uses billions of measurements from satellites, ships, aircraft and weather stations to track key climate metrics.

    Whether pumped out the chimney of a coal-burning power plant or ejected from the exhaust pipe of a passenger plane, each carbon molecule clogging the Earth’s atmosphere traps heat and warps weather.

    “This is not good news at all,” said Aditi Mukherji, a director at research institute CGIAR and co-author of the latest Intergovernmental Panel on Climate Change (IPCC) report.

    François Gemenne, an IPCC author and director of the Hugo Observatory at the University of Liège, said the climate crisis is not a binary issue.
