Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

The United Nations Environment Programme (UNEP) is stepping up its work on mapping zoonotic threat and protecting the environment to reduce the risk of future pandemics, such as the COVID-19 crisis currently sweeping the globe.
An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
As more frequent droughts and floods threaten the global food supply, humans are increasing their demands on water and land,... The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.

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 document describes the essential interventions in mental health and psychosocial support (MHPSS) that should be developed on an intersectoral basis in countries and communities. Its frame of reference is the Inter-Agency Standing Committee (IASC) intervention pyramid for MHPSS services. The pyr...amid shows different levels of support, ranging from social considerations, safety, and basic needs, to the provision of specialized services for the management of more severe conditions, as well as the probable volume of demand at each established level.

Climate change has direct impacts on human health, but those impacts vary widely by location. Local health impacts depend on a large number of factors including specific regional climate impacts, demographics and human vulnerabil...ities, and existing local adaptation capacity. There is a need to incorporate local data and concerns into climate adaptation plans and evaluate different approaches.

Preparedness planning is essential in order to respond effectively to outbreaks, including single case occurrences of highconsequence infectious diseases (HCID), such as the importation of a viral haemorrhagic fever (VHF) case
This document outlines PAHO’s regional priorities for the year 2023 to sustain and scale up health emergency and humanitarian assistance in the Americas, with a focus on five priority countries currently facing a prolonged humanitarian crisis and recovering from recent acute emergencies: Colombia,... El Salvador, Guatemala, Haiti, and Venezuela (Bolivarian Republic of). These goals align with and build on the World Health Organization’s Global Health Emergency Appeal for 2023, its principles, priorities, and strategies.

WHO needs US$2.54 billion to provide life-saving assistance to millions of people around the world facing health emergencies. WHO’s Health Emergency Appeal is a consolidation of WHO’s priorities and financial requirements for 2023 to carry out health interventions in emergency and humanitarian r...esponses. The number of people in need of humanitarian relief has increased by almost a quarter compared to 2022, to a record 339 million. WHO is responding to an unprecedented number of intersecting health emergencies: climate change-related disasters such as flooding in Pakistan and food insecurity across the Sahel in the greater Horn of Africa; the war in Ukraine; and the health impact of conflict in Yemen, Afghanistan, Syria and north eastern Ethiopia – all of these emergencies overlapping with the health system disruptions caused by the COVID-19 pandemic and outbreaks of measles, cholera, and other killers. Contributions to the appeal can be fully flexible, flexible across a region, or flexible within a country appeal.

The Planetary Health Report Card is a student-driven, metric-based initiative to inspire planetary health and sustainable healthcare education engagement in medical schools. In addition to inspiring expansion of medical school curricula, we hope to inspire medical schools to expand research efforts,... engage with communities most affected by climate change and environmental injustice, support passionate medical students who are trying to organize around planetary health at the institutional level, and implement sustainable practices. A set of metrics in these five category areas allows students and faculty to conduct a needs assessment at their medical school.
