Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

For the first time, we are forced to consider the real risk of destabilizing the entire planet," says climate impact scholar Johan Rockström. In a talk backed by vivid animations of the climate crisis, he shows how nine out of the 15 big biophysical systems that regulate the climate -- from the per...mafrost of Siberia to the great forests of the North to the Amazon rainforest -- are at risk of reaching tipping points, which could make Earth uninhabitable for humanity. Hear his plan for putting the planet back on the path of sustainability over the next 10 years -- and protecting the future of our children.

Climate change is already having severe impacts across our planet, bringing new and previously unimaginable challenges to the people least responsible for greenhouse gas emissions.
This report, the first we’ve released jointly in the history of our organizations, provides a sobering review of h...ow just one of those challenges – the increase in deadly heat-waves – threatens to drive new emergency needs in the not-so-distant future.

Overview.
The COVID-19 pandemic is the latest crisis facing the world, but unless humans release their grip on nature, it won’t be the last, according to a new report by the United Nations Development Programme (UNDP), which includes a new experimental index on human progress that takes into acco...unt countries’ carbon dioxide emissions and material footprint.
The report lays out a stark choice for world leaders - take bold steps to reduce the immense pressure that is being exerted on the environment and the natural world, or humanity’s progress will stall.

Agriculture is highly exposed to climate change, as farming activities directly depend on climatic conditions. Agriculture also contributes to climate change through the release of greenhouse gases into the atmosphere. Two powerful greenhouse gases are by-products of agricultural activity:
Methan...e (CH4) – from livestock digestion processes and stored animal manure;
Nitrous oxide (N2O) – from organic and mineral nitrogen fertilisers.
However, agriculture can also contribute to climate change mitigation by reducing greenhouse gas emissions and by sequestering carbon while maintaining food production.

Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the ...role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate–disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

The One Health (OH) High-Level Expert Panel (OHHLEP) of the Quadripartite Organizations defined OH as an integrated, unifying approach that aims to sustainably balance and optimize the health of peo...ple, animals and ecosystems.”
It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and interdependent [1]. The Tripartite which comprised the Food and Agriculture Organization (FAO) of the United Nations (UN), the World Health Organization (WHO), and the World Organisation for Animal Health (WOAH) later became the Quadripartite organizations when the United Nations Environment Programme (UNEP) joined the OH alliance in 2022. There are Global and Regional Quadripartite Secretariats consisting of officials of headquarters and regional offices, respectively.
Over the years, the Tripartite/Quadripartite organizations and other partner agencies have developed several OH assessment and operational tools to support Member States in assessing their core capacities to achieve compliance with the requirements of international standards such as the International Health Regulations 2005 (IHR), WOAH’s Terrestrial and Aquatic Animal Health Codes, World Trade Organization’s Sanitary and Phytosanitary Measures (WTO-SPS), FAO/WHO Codex standards, etc. Technical areas that the existing tools currently support include progress monitoring, coordination and collaboration mechanisms, and capacity building for prevention, detection, preparedness, and response to health threats emerging at human-animal-environment interface. More OH B operational tools are in the pipeline.

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 Eur...ope 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.

Air pollution is a major environmental risk factor and contributor to chronic, noncommunicable diseases (NCDs). However, most public health approaches to NCD prevention focus on behavioural and biomedical risk factors, rather than environmental risk... factors such as air pollution. This article discusses the implications of such a focus. It then outlines the opportunities for those in public health and environmental science to work together across three key areas to address air pollution, NCDs and climate change: (a) acknowledging the shared drivers, including corporate determinants; (b) taking a ‘co-benefits’ approach to NCD prevention; and (c) expanding prevention research and evaluation methods through investing in systems thinking and intersectoral, cross-disciplinary collaborations.
