The French president has called for action at a climate summit in Paris attended by heads of state and scientists before Cop28
France will spend €1bn (£880m) on polar research between now and 2030, amid rapidly rising scientific concern over the world’s melting ice caps and glaciers.
A new polar science vessel will spearhead the effort, and France is calling for a moratorium on the exploitation of the seabed in polar regions, to which the UK, Canada, Brazil and 19 other countries have so far signed up.
French president Emmanuel Macron told a summit of heads of state and scientists in Paris: “We are not talking about a threat for tomorrow, but one that is already present and accelerating. We are talking about a transformation of the cryosphere [the Earth’s ice] that already threatens millions and will threaten billions of the planet’s inhabitants with multiple direct and indirect consequences.”
The plight of the Earth’s polar regions and glaciers has sparked alarm among many scientists, as heatwaves at both poles, which were seen for the first time last year, look set to be a regular occurrence.
This year is already the hottest on record and probably the hottest in 100,000 years, with ocean temperatures so far above normal as to be, in the words of one scientist, “gobsmackingly bananas”.

They heard from polar and glacier experts that temperatures were rising four times more rapidly in the Arctic than the global average, half the world’s 200,000 glaciers were set to disappear by the end of the century and that the rate of sea level rise had doubled in the last two decades.

Glaciers were melting across the world, warned the head of the World Meteorological Organisation, Petteri Taalas. As they vanish irrecoverably, more than 1 billion people who depend on them for water and agriculture will face increasingly severe shortages. As well as cutting greenhouse gas emissions overall, there are also urgent measures that scientists believe could be taken now that would reduce or delay the risk of the collapse of glaciers or a tipping point at the poles.
