The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. The IPCC prepares comprehensive Assessment Reports about the state of scientific, technical and socio-economic knowledge on climate change, its impacts and future risk...s, and options for reducing the rate at which climate change is taking place. It also produces Special Reports on topics agreed to by its member governments, as well as Methodology Reports that provide guidelines for the preparation of greenhouse gas inventories.

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 2021: The Physical Science Basis. Contribution of Working Group I to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change
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.

Changes in climate, in conjunction with other drivers of mobility, shape human migration. While there is an increasing focus on the adaptive potential of migration, the health impacts of climate-related migration, including planned relocation and forced displacement, have not been thoroughly examine...d. The Intergovernmental Panel on Climate Change stated that migration is currently, and will increasingly be, influenced by environmental degradation and climate change, and that it needs to be addressed in a focused and coordinated manner

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.

As scientists of the UN’s Intergovernmental Panel on Climate Change meet in Geneva this week to publish their Special Report on Climate Change and Land (August 8), a new report by the development charity Christian Aid shows that climate change is having a disproportionate impact on the food systems of the country’s least responsible for causing the climate crisis.
The IPCC is expected to show how climate change will affect global food supply, spiking prices and reducing nutrition. It is also likely to recommend that countries will need to drastically cut emissions if global food security is to be protected.

Climate change presents the single biggest threat to human development, and its widespread impacts disproportionately burden the poorest and most vulnerable households in fragile and rural developing contexts – particularly women and children.
According to the Intergovernmental Panel on Climate C...hange’s (IPCC) latest report, ‘between 2010 and 2020, droughts, floods and storms killed 15 times as many people in highly vulnerable countries, particularly in Africa — which is responsible for less than 3 percent of global emissions – than in the wealthiest countries’.
Recognising environmental degradation and climate change are key accelerators of extreme child vulnerability, World Vision (WV) approved the Environmental Stewardship Management Policy (‘the Policy’) and Guidelines (‘the Guidelines’) in 2021.
To support the implementation of the Policy and Guidelines, WV has developed this Environmental Stewardship and Climate Action Handbook (‘the Handbook’) to help offices across the WV Partnership implement best practice environmental management strategies both in the field and in our operations and facilities.
Integrating environmental stewardship and climate action into all our work – whether that be in our Area Programmes, grant projects, responses to disasters or advocacy – is critical to achieving WV’s strategy.
As a Christian organisation we are compelled to follow the ways of Jesus Christ, calling us to care for the ‘least of these’ (Matthew 25:40) – the vulnerable children who are disproportionately impacted by climate change. Our response to the degradation of the environment is not motivated by political expediency or funding – but because we are called to steward God’s creation (Genesis 1:28).

Climate Change 2021: The Physical Science Basis. Contribution of Working Group I to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change
Climate change is one of the most urgent challenges for people and ecosystems worldwide. The recently published sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) stresses the occurrence of widespread adverse impacts of climate change. Increased frequency and inten...sity of extreme weather events, as well as slow-onset processes cause enormous losses and damages to human and natural systems. Marginalized groups and people in vulnerable situations are often disproportionally affected. While the impacts of climate change already become more tangible and threatening, action for addressing them remains insufficient. Adaptation to climate change is, thus, becoming a necessity for governments, companies, and private citizens.
To provide practical and scientifically sound guidance on how to conduct vulnerability assessments, GIZ published its Vulnerability Sourcebook in 2014. The Vulnerability Sourcebook was used in over twenty different GIZ partner countries and provides a step-by-step guidance for designing and implementing a vulnerability assessment. It is also one of the methodological foundations for the ISO 14091:2021 standard on vulnerability, impacts and risk assessment for climate change adaptation.

In 2018, the Intergovernmental Panel on Climate Change announced that to restrict global temperature rise to 1·5°C, greenhouse gas emissions must decrease 45% by 2030 compared with 2010, and reach net zero by 2050.1
In Climate Change 2014: Impacts, Adaptation, and Vulnerability. Part A: Global and Sectoral Aspects. Contribution of Working Group II to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change
The climate crisis has many consequences – among them widespread health impacts that will lead to immense societal, ecological, and economic harm.
Over the past two decades multiple large-scale reviews on climate change and health have made clear the need for a multi-sectoral approach to target t...he drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.
