Global Humanitarian Overview 2023

The climate crisis is a humanitarian crisis

Climate change is contributing to humanitarian crises worldwide. Climate-related disasters are driving increased levels of risks, vulnerability human rights abuses, disrupting livelihoods, increasing displacement, influencing the spread of diseases, worsening global public health and threatening lives overall. The past eight years are on track to be the eight warmest on record, and 2022 is estimated to be among the hottest, with a mean temperature of 1.15°C above pre-industrial times. This is taking an exceptionally heavy toll on glaciers, with initial indications of record-shattering melt and record levels of ocean heat.,

Disasters triggered more than 60 per cent (23.7 million people) of the newly recorded internal displacements in 2021. Ninety-four per cent of these displacements were climate related. Countries that are highly vulnerable to the impacts of climate change also saw 95 per cent of all conflict-related displacements in 2021. Almost all conflict-related refugees who returned in 2021 (99 per cent) returned home to countries on the front line of the climate crisis, making safe and sustainable solutions harder to achieve.

Climate-related disasters almost tripled this decase compared to the 1980s

Climate change continues to exacerbate the frequency and intensity of disasters, disproportionately impacting the most vulnerable people. The effects of these disasters deepen inequalities and exacerbate pre-existing human rights, and social and structural vulnerabilities. Floods and storms accounted for 91 per cent of disaster displacements in 2021, a year that saw 432 individual disasters. If current trends persist, the number of disaster events per year is projected to reach 560, or 1.5 large-scale disasters per day. An extreme-heat event that would have occurred once in 50 years in a climate without human influence is now nearly five times as likely.

As temperatures rise, water scarcity continues. Despite progress in recent years, 2 billion people still do not have access to safe drinking water, and 1.5 million people die every year from diarrhoea caused by unsafe drinking water, most of them infants and small children. Wide geographical disparities exist, and every day, millions of women and school-aged children, often girls, walk long distances to fetch water for the family. Only one third of health-care facilities in Least Developed Countries have water available from a safe source. Progress towards universal access to water is threatened by the impacts and uncertainty of climate change, agricultural and ecological needs, competing financial priorities and existing threats to water quality.

People caught in humanitarian crises contribute the least to global warming, yet they are the most vulnerable to its impacts. Of the 15 countries most vulnerable to the climate crisis, 12 had an internationally led humanitarian response. Those countries contributed less than 0.2 per cent of global greenhouse gas emissions in 2020. The majority of the emergencies are protracted crises, such that humanitarian workers have become a constant presence and lifeline for affected communities. By the end of the century, deaths from extreme heat are projected to be comparable in magnitude to all cancers or all infectious diseases and staggeringly unequal, with people in poorer countries seeing far greater levels of increase.

Vulnerability to climate change (2020)

This growing humanitarian climate emergency requires significant investment in humanitarian programmes that boost the resilience and adaptative capacities of vulnerable communities and ensure they receive climate adaptation funds to manage the risks they face. Less than 18 per cent of climate adaptation finance allocated in 2019 went to countries with an HRP. The participation of people affected by climate change will be critical to ensure responsive, accountable and effective humanitarian programming. Unless policy and prevention and mitigation measures are put in place now, climate change will continue being a leading driver of humanitarian need.
