Climate risks have significant effects on public health including: injury, death, communicable diseases such as vector-borne and water-borne diseases, and non-communicable impacts such as malnutrition, heat stress and health effects of air pollution.
The devastating impacts of the 2015–16 El Niño will be felt well into 2017. This crisis was predicted, yet overall, the response has been too little too late. The looming La Niña event may further hit communities that are already deeply vulnerable. To end this cycle of failure, there is an urgen...t need for humanitarian action where the situation is already dire, to prepare for La Niña later this year, to commit to comprehensive new measures to build communities’ resilience, and to mobilize global action to address climate change which is creating a ‘new normal’ of higher temperatures, drought and unpredictable growing seasons.

Climate change is the single biggest health threat facing humanity, and health professionals worldwide are already responding to the health harms caused by this unfolding crisis.
The Intergovernmental Panel on Climate Change (IPCC) has concluded that to avert catastrophic health impacts and prevent... millions of climate change-related deaths, the world must limit temperature rise to 1.5°C. Past emissions have already made a certain level of global temperature rise and other changes to the climate inevitable. Global heating of even 1.5°C is not considered safe, however; every additional tenth of a degree of warming will take a serious toll on people’s lives and health.

Asia-Pacific Disaster Report 2017
The report looks at the extent and impact of natural disasters across the region and how these intersect with poverty, inequality and the effects of violent conflict. But it also shows how scientific and other advances have increased the potential for building di...saster resilience and ensuring that even in the most extreme circumstances people can survive disaster impacts and rebuild their communities and livelihoods.
Disaster resilience is a key element of the 2030 Agenda for Sustainable Development. The Sustainable Development Goals are based on the premise of reaching absolutely everyone. When the drought is assessed, when the flood warnings are broadcast, when the tsunami siren sounds, the aim is to ‘leave no one behind’.

Recently, Sri Lanka has been impacted by multiple natural disasters. Sri Lanka experienced a landslide in October 2014, and flooding in December 2014.8 Sri Lanka withstood the worst drought conditions witnessed in four decades in 2016; the extreme drought conditions extended into 2017 and produced s...ubstantial economic and social effects. The drought was responsible for an increase in national poverty levels, due to reduced cultivation income, especially for rural farmers. ... In May 2017, Sri Lanka experienced continuous rains causing flash floods and extreme devastation. However, despite natural disasters and challenges posed by a complex political environment, Sri Lanka’s financial performance remained largely satisfactory in the first half of 2017.

Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19.
2020 was one of the three warmest years on record. The past six years, including 2020, have been the si...x warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle.
The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change.

Climate change is resulting in poorer health outcomes, increasing mortality and is a driver of health inequities. However, health is well placed to be a significant part of the solution; the positive health impacts from stronger climate change action can motivate stronger global ambition; health sys...tems which are resilient to climate change can help protect their populations from the negative impacts (in the short and longer terms); and sustainable low carbon health systems can make a substantial contribution to reducing national and global emissions.
This fact sheet on climate change and health is part of the Climate Fast Facts series of the United Nations Climate Action team.

The threat climate change poses to health, equity, and development has been rigorously documented. However, in an era marked by economic crisis, regional conflicts, natural disasters and growing disparities between rich and poor, the joint global actions required to address climate change have been ...vigorously debated – and critical decisions postponed.
This document, part of WHO’s Health in the Green Economy series, describes how many climate change measures can be “win-wins” for people and the planet.
These policies yield large, immediate public health benefits while reducing the upward trajectory of greenhouse gas emissions. Many of these policies can improve the health and equity of people in poor countries and assist developing countries in adapting to climate change that is already occurring, as evidenced by more extreme storms, flooding, drought and heatwaves.
WHO’s Department of Public Health and Environment launched the Health in the Green Economy initiative in 2010 to review potential health and equity “co-benefits” of proposed climate change measures – as well as relevant risks.
This review examines mitigation strategies discussed in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change which constitutes the most broad-based global review of mitigation options by scientific experts.

Addressing gaps and improving health system performance is simply not enough to prepare a health system to tackle the effects of the climate crisis. Climate change’s impact on the health and well-being of people globally is reaching catastrophic levels. As the earth continues to warm, tens of mill...ions of people are at increased risk from rapid and unpredictable spread of infectious diseases, heatwaves, water and food insecurity and scarcity, air pollution, poverty and homelessness. Health services are often regarded as a first line defense in preventing adverse health outcomes, especially from those caused by climate impacts

Climate change creates and exacerbates circumstances conducive to gender-based violence. Climate action must tackle gender-based violence.
The WHO health advisory provides guidance to countries on adapting all existing preparedness and response plans and procedures for natural hazards such as cyclones, tropical storms, tornadoes, floods, earthquakes and potential outbreaks of other diseases to their existing COVID-19 strategic prepared...ness and response plans. It advises countries to sustain all established public health and social measures to prevent and control COVID-19 while simultaneously preparing for responding to and effectively manage other disaster risks and events. It highlights WHO’s call for local, national, regional and global solidarity to support countries and communities with high levels of vulnerability to natural hazards during the COVID-19 pandemic.

Colombia is characterized by a fragile and prolonged humanitarian context marked by recurrent multi-hazards affecting its territories and combined with severe structural and systemic challenges within the health system. Recent shocks, including the
COVID-19 pandemic, growing violence within the Col...ombian territories and along the border with Venezuela (Bolivarian Republic of), and repetitive hydro-meteorological disasters over the last 12 months aggravate such chronic challenges.
In 2022, the number of people in need of humanitarian assistance increased by 300 000 due to deteriorating indicators of maternal and child mortality, pregnancy in adolescent girls, human immunodeficiency virus (HIV), suicides, sexually transmitted
infections (STIs), gender-based and sexual violence, and communicable diseases. increasing population trends, primarily due to mass migration movements and the persistence of armed conflicts, create access barriers to essential health services, mobility restrictions, and forced displacement, further impacting the health, lives, and well-being of populations in vulnerable situations. In many territories, geographical distance to health facilities and attacks against medical missions hinder providing appropriate healthcare.

Climate-induced water insecurity poses one of the biggest threats to humanity and will lead to more hunger, disease and displacement
Oxfam water engineers are having to drill deeper, more expensive and harder-to-maintain water boreholes used by some of the poorest communities around the world, mo...re often now only to find dry, depleted or polluted reservoirs.
Today, during World Water Week, Oxfam publishes the first of its series of reports, “Water Dilemmas”, about the growing water crisis, in large part driven by global heating from greenhouse gas emissions. The report describes how climate change will impact water security in different regions, leading to more hunger, disease and displacement.
Carlos Calderon, Humanitarian Advocacy and Partnerships Lead for Oxfam Aotearoa said, “This new Oxfam research is focused on the global Water, Sanitation and Hygiene (WaSH) situation, but it paints a picture that illustrates the complexity of elements that, combined, will continue to increasingly affect women, girls, boys and men in the decades to come. Changing weather, poverty, inequality, gender-based violence, political instability and conflicts are impacting the availability and quality of adequate water systems. All governments, particularly those from rich countries, should responsively take action at a global scale. The clock is ticking. Our children will judge us for our actions today, or for the lack of them.”

In 2024, we need US$1.5 billion to provide live-saving health care to millions of people in emergencies. An alarming combination of conflict, climate-related threats and increasing economic hardship mean an estimated 166 million people require health assistance.
Beat the heat: child health amid heatwaves in Europe and Central Asia finds that half of these children died from heat-related illnesses in their first year of life. Most children died during the summer months.
"Around half of children across Europe and Central Asia – or 92 million children –... are already exposed to frequent heatwaves in a region where temperatures are rising at the fastest rate globally. The increasingly high temperatures can have serious health complications for children, especially the youngest children, even in a short space of time. Without care, these complications can be life-threatening,” said Regina De Dominicis UNICEF Regional Director for Europe and Central Asia.
Heat exposure has acute effects on children, even before they are born, and can result in pre-term births, low birth weight, stillbirth, and congenital anomalies. Heat stress is a direct cause of infant mortality, can affect infant growth and cause a range of paediatric diseases. The report also notes that extreme heat caused the loss of more than 32,000 years of healthy life among children and teenagers in the region.
As the temperatures continue to rise, UNICEF urges governments across Europe and Central Asia to:
- Integrate strategies to reduce the impact of heatwaves including through National Determined Contributions (NDC), National Adaptation Plans (NAP), and disaster risk reduction and disaster management policies with children at the centre of these plans
Invest in heat health action plans and primary health care to more adequately support heat-related illness among children
- Invest in early warning systems, including heat alert systems
- Adapt education facilities to reduce the temperatures in the areas children play in and equip teachers with skills to respond to heat stress
- Adapt urban design and infrastructure including ensuring buildings, particularly those housing the most vulnerable communities are equipped to minimize heat exposure
- Secure the provision of safe water, particularly in countries with deteriorating water quality and availability.
UNICEF works with governments, partners and communities across the region to build resilience against heatwaves. This includes equipping teachers, community health workers and families with the skills and knowledge to respond to heat stress.
