Surging Seas Are Coming For All Of Us, UN Secretary-General Warns

The United Nations Secretary-General António Guterres has emphasised that major polluters must reduce emissions to avoid a global catastrophe. "The Pacific is today the most vulnerable area of the world," he announced at the Pacific Island Forum Leaders Meeting in Tonga. "There is an enormous injustice in relation to the Pacific and it's the reason I am here."

During his speech at the forum, Guterres warned that "surging seas are coming for us all," as the UN released reports on rising sea levels threatening Pacific island nations. He highlighted that small islands contribute minimally to climate change but suffer its worst effects.

Rising Sea Levels and Climate Change

The World Meteorological Organization's State of the Climate in the South West Pacific report indicates a triple threat: accelerating sea level rise, ocean warming, and acidification. Guterres stated, "The reason is clear: greenhouse gases – overwhelmingly generated by burning fossil fuels – are cooking our planet." He added, "The sea is taking the heat – literally."

This year's forum theme, transformative resilience, was tested when heavy rains flooded a new auditorium and an earthquake caused evacuations. Joseph Sikulu, Pacific director at 350, a climate change advocacy group, remarked on how volatile conditions highlight the need for preparation.

The UN Climate Action Team's report titled "Surging Seas in a Warming World" reveals that global average sea levels have risen at unprecedented rates over the past 3,000 years. In some parts of the tropical Pacific, sea levels have increased by up to 15cm in 30 years.

Guterres urged world leaders to drastically cut emissions and phase out fossil fuels while boosting climate adaptation investments. He stressed that limiting global warming to 1.5°C is crucial to prevent irreversible damage.

"Only by limiting warming to 1.5 degrees Celsius do we have a fighting chance of preventing the irreversible collapse of the Greenland and West Antarctic ice sheets," he said. This requires cutting global emissions by 43% from 2019 levels by 2030 and 60% by 2035.

He also pointed out that last year saw a rise in global emissions by 1%. The G20 nations, responsible for 80% of emissions, must lead efforts to reduce them significantly.

The Secretary-General highlighted emerging science suggesting that a two-degree temperature rise could lead to catastrophic ice sheet collapses and unstoppable sea level rise over millennia. He warned that without drastic cuts to emissions, Pacific Islands could see an additional 15cm rise in sea levels by mid-century.

"Surging seas are coming for us all," Guterres reiterated, noting that coastal megacities worldwide face increased risks from rising seas and extreme weather events.

Looking ahead to this year's UN climate conference, Guterres called for innovative financing and richer nations fulfilling commitments like doubling adaptation finance to $40 billion annually by 2025. He also stressed significant contributions to the Loss and Damage Fund supporting vulnerable countries.

The Early Warnings for All initiative aims to ensure lifesaving systems are in place globally by 2027. This involves enhancing countries' data capacities for better decision-making on adaptation and coastal planning.

The Secretary-General concluded with a stark reminder: "If we save the Pacific, we also save ourselves." The world must act urgently before it is too late.
