UN Climate Change chief Simon Stiell has urged countries to deliver a rapid surge in climate finance ahead of COP30, warning that developing nations remain dangerously short of the resources needed to withstand worsening storms, floods and droughts.

From the rainforests of Central America to low-lying atolls in the Pacific and drought-stricken plains in Africa, leaders came to the United Nations General Assembly on Wednesday with a common message: climate change is no longer a distant threat, but an immediate danger demanding bolder global commitments.

From accelerating the move to clean energy to planting acres of trees, leaders from nearly 100 countries announced or reiterated new national climate action plans during a meeting on Wednesday as part of the high-level week of the UN General Assembly.

The head of theUNFCCCon Tuesday called for finance to flow right now, as delegates prepare to head for the Brazilian city of Belm next month for what is being seen as a crunch summit for turning promises into action.

Whether or not countries need to be prepared to cope with a changing, more unpredictable climate is hardly in question: extreme weather events such as devastating wildfires, catastrophic droughts and apocalyptic floods are making life increasingly difficult in all parts of the world (or even, as the inhabitants of sinking Pacific island Statesare finding, impossible).

There are plenty of examples of effective measures that countries can take to adapt to this new normal, ranging from high sea walls to cyclone warning systems, floating homes and planting drought-tolerant crops.

However, it all costs money. A lot of money.Estimatesfrom the UN Environment Programme (UNEP) put the figure at somewhere between $160 and $340 billion but just a tiny fraction of that amount is actually getting to developing countries.

Livelihoods destroyed

On Tuesday, UN Climate Change released a newreportdetailing the progress countries are making on their national climate adaptation plans (NAPs). It confirms that the persistent funding gap risks scuppering plans that many are attempting to implement.

Speakingat the launch in the Brazilian capital, Brasilia, Simon Stiell reminded that the climate crisis is destroying lives and livelihoods in every region of the world, especially in the most vulnerable countries, and thatadaptation is not optional; it is absolutely essential.

The UN climate chief said adaptation would not only protect lives but also help empower communities and countries to thrive.

National Adaptation Plans, he declared, arekey to unleashing the epic transformative power of investing in climate resilience.

Plans up and running

Aside from the funding challenge, progress is being made: 67 developing countries have submitted plans including 23 from least developed countries and 14 small island developing States with an approach aimed at engaging more women, young people, Indigenous Peoples, local communities and the private sector.

These efforts explain in detail what the priorities and needs are and should, Mr. Stiell suggested, make it more straightforward for investors and financial institutions to fund climate adaptation.

The report comes 19 days before the opening of the COP30 UN climate conference in the Amazonian city of Belm, where adaptation and the funding gap will be a central issue for negotiators, with the aim of mobilising 1.3 trillion dollars in climate finance.

Looking ahead to the UN summit, Mr. Stiell said it was a key test of global solidarity, that mustconnect climate action to real lives everywhere, to spread the vast benefits.
