Humans can adapt to climate change by making themselves less vulnerable to its effects. Adaptation strategies include things like moving to higher ground to avoid rising sea levels, planting new crops that will thrive in new climate conditions, and using new building technologies. Adaptation frequently necessitates monetary investment in new or improved research, technology, and infrastructure.
According to a new United Nations Environment Program (UNEP) report, as climate impacts intensify around the world, nations must dramatically increase funding and implementation of actions designed to assist vulnerable nations and communities in adapting to the climate storm.
The Adaptation Gap Report 2022: Too Little, Too Slow was released ahead of COP27, the latest round of climate talks taking place in Sharm El-Sheikh, Egypt. Climate adaptation failure puts the world at risk, according to a study that finds global efforts in adaptation planning, financing, and implementation are falling behind the growing risks.
“Climate change is landing blow after blow upon humanity, as we saw throughout 2022: most viscerally in the floods that put much of Pakistan under water,” said Inger Andersen, Executive Director of UNEP. “The world must urgently reduce greenhouse gas emissions to limit the impacts of climate change. But we must also urgently increase efforts to adapt to the impacts that are already here and those to come.
“Nations need to back the strong words in the Glasgow Climate Pact with strong action to increase adaptation investments and outcomes, starting at COP27.”

Climate risks rising
A multiyear drought in the Horn of Africa, unprecedented flooding in South Asia and severe summer heat across the northern hemisphere point to mounting climate risks. These impacts are coming at only 1.1°C above pre-industrial temperatures.
According to UNEP’s Emissions Gap Report—the recently released sister publication of the Adaptation Gap Report—Nationally Determined Contributions (NDCs) under the Paris Agreement point towards global warming of 2.4–2.6°C by the end of the century. Research from the Intergovernmental Panel on Climate Change (IPCC) says that climate risks will intensify with each tenth of a degree.
Such trends mean that adaptation must take center stage alongside mitigation in the global response to climate change, the report finds. Since even ambitious investments in adaptation cannot fully prevent climate impacts, losses and damages must also be addressed.
Progress on adaptation slow and spotty
The report finds that more than eight out of ten countries have at least one national adaptation planning instrument, and they are getting better and more inclusive. One third of the 197 country Parties to the UN Framework Convention on Climate Change (UNFCCC) have incorporated quantified and time-bound targets on adaptation. Meanwhile, nearly 90% of planning instruments analyzed display consideration for gender and disadvantaged groups, such as Indigenous peoples.
However, financing to turn these plans into action isn’t following. International adaptation finance flows to developing countries are 5–10 times below estimated needs and the gap continues to widen. International adaptation finance flows to developing countries reached USD 29 billion in 2020, as reported by donor countries, an increase of 4% from 2019.
Combined adaptation and mitigation finance flows in 2020 fell at least USD 17 billion short of the USD 100 billion pledged to developing countries. Significant acceleration is needed if a doubling of 2019 finance flows by 2025 is to be met, as urged by the Glasgow Climate Pact.
Estimated annual adaptation needs are USD 160–340 billion by 2030 and USD 315–565 billion by 2050. Implementation of adaptation actions—concentrated in agriculture, water, ecosystems, and cross-cutting sectors—is increasing, but not keeping up with climate impacts. Without a step change in support, adaptation actions could be outstripped by accelerating climate risks.
A united approach
According to the report, integrating adaptation and mitigation actions, such as nature-based solutions, from the start in planning, finance, and implementation can increase co-benefits. It may also limit potential trade-offs like hydropower reducing food security or irrigation increasing energy consumption.
The authors conclude that increased adaptation investments and outcomes require strong political will. International efforts to increase adaptation must not be derailed by crises such as the war in Ukraine and the COVID-19 pandemic. Unprecedented political will and longer-term adaptation investments are urgently needed to keep the adaptation gap from widening.
