Global Ice Loss Crosses a Critical Climate Threshold

WHO:

Phys.org - The study concerns the cryosphere: ice sheets, mountain glaciers, sea ice, permafrost and snow cover.

Wired Science - Humanity has thrived thanks to a stable cryosphere.

WHAT:

Phys.org - Research published in *Science* finds that human-driven climate change is degrading the cryosphere beyond safe environmental limits.

Phys.org - The study warns that this degradation systematically threatens Earth-system conditions on which humanity depends.

Wired Science - The world’s ice has been pushed out of its “safe zone.”

Wired Science - Burning fossil fuels has increased the risk of “accelerating and partly irreversible” harm to the planet’s cold places.

WHERE:

Phys.org - The research warning was issued at COP31.

Wired Science - The reported harm concerns the planet’s cold places.

WHY:

Phys.org - Human-driven climate change is degrading frozen parts of the planet beyond safe environmental limits.

Wired Science - Burning fossil fuels has increased the risk of harm to the world’s ice and other cold places.

Human-driven climate change has pushed Earth’s cryosphere beyond safe environmental limits, researchers warn. The threatened frozen regions include ice sheets, glaciers, sea ice, permafrost, and snow. Fossil fuel burning raises risks of accelerating, partly irreversible harm to Earth’s cold places.
