Knowing how to appeal to apocalyptic fear, political fear, and private fear will help a leader name reality in a credible manner and assess which fear to prioritize at a given time.

Permafrost and glaciers in the high Arctic form an impermeable ‘cryospheric cap’ that traps a large reservoir of subsurface methane, preventing it from reaching the atmosphere. Cryospheric vulnerability to climate warming is making releases of this methane possible. On Svalbard, where air temperatures are rising more than two times faster than the average for the Arctic, glaciers are retreating and leaving behind exposed forefields that enable rapid methane escape. Here we document how methane-rich groundwater springs have formed in recently revealed forefields of 78 land-terminating glaciers across central Svalbard, bringing deep-seated methane gas to the surface. Waters collected from these springs during February–May of 2021 and 2022 are supersaturated with methane up to 600,000 times greater than atmospheric equilibration. Spatial sampling reveals a geological dependency on the extent of methane supersaturation, with isotopic evidence of a thermogenic source. We estimate annual methane emissions from prog

Russia’s war in Ukraine has earned Norway billions – and caused controversy. Thanks to oil and gas reserves in the waters off its coast, Norway is not only extremely rich but getting richer still. Already the World Bank’s seventh wealthiest country by GDP per capita at the start of this year, the resource-rich Scandinavian country’s profits have ballooned to record levels over the last 12 months, as prices on the energy markets tripled due to Russia’s invasion of Ukraine and Norway replaced bellicose Moscow as Europe’s largest supplier of gas.
