SINGAPORE – Extreme weather in Antarctica, including ocean heat waves and ice loss, is set to become more intense unless urgent policy action reduces the burning of fossil fuels, a new study has found – the latest to sound the alarm on the damage climate change is unleashing.
Scientists have become increasingly alarmed on how the Antarctic ice has struggled to grow back after– a deviation so extreme from the normal that it’s been dubbed a “six sigma event,” or once-in-a-7.5-million-year phenomenon. The Arctic, too, is expected to be ice-free in summers by 2030, underscoring the rapid pace at which global warming is damaging the planet’s ecosystems.
The world’s most extreme heat wave was recorded in east Antarctica. Temperatures hit 38.5 deg C above the seasonal normal there in 2022, according to the study that has reviewed climate extremes in Antarctica and the Southern Ocean. The study concludes that Antarctica is likely to face considerable stress and damage in the coming decades. Twelve countries including the UK, US, India and China pledged to preserve the continent’s fragile environment through the Antarctic Treaty in 1959. The study says some countries risk breaching the terms of this agreement without urgent action to reduce emissions.
