The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.

This guidance aims to enhance the capacity of health care facilities to protect and improve the health of their target communities in an unstable and changing climate. The document also intends to empower health care facilities to be environmentally sustainable, by optimizing the use of their resources and minimizing the release of waste into the environment. Climate resilient and environmentally sustainable health care facilities contribute to high quality of care and accessibility of services, and by helping reduce facility costs also ensure better affordability. 

This document aims to:

  • Guide professionals working in health care settings to understand and effectively prepare for the additional health risks posed by climate change.
  • Monitor, anticipate, manage and adapt to the health risks associated with climate change.
  • Guide health care facility officials to work with health determining sectors (including water and sanitation, energy, transportation, food, urban planning, environment) to prepare for additional health risks posed by climate change through a resilience approach, and to promote environmentally sustainable practices in providing these services.
  • Provide tools to assist health care facility officials assess their resilience to climate change threats, and their environmental sustainability based upon the appropriate use of resources (in particular water and energy and sustainable procurement), and release of hazards (biological, chemical, radiological), to their surrounding environment.
  • Promote actions to ensure that health care facilities are constantly and increasingly strengthened and continue to be efficient and responsive to improve health and contribute to reducing inequities and vulnerability within their local settings.

Heatwaves are deadly and their impacts are on the rise globally due to climate change. People living in urban areas are amongst the hardest hit when a heatwave occurs because these are hotter than the surrounding countryside. It is crucial that cities incorporate heat-reduction tactics such as green spaces into their plans for growth or retrofit them in built areas; this emergency can only be avoided if city institutions, community groups, and planners contribute to reducing heat risk now and in the future. This guide is intended to help city staff take the first steps to understanding the heat risks they face, develop an early warning system, work with partners to consolidate heat action plans, and adapt urban planning practices.

This report is the culmination of a workshop and webinars exploring activities, resources, capabilities, and challenges to the prediction of infectious diseases at sub-seasonal and seasonal time scales. The webinars and workshop were led by a steering committee that included members from the U.S. Global Change Research Program’s Interagency Group on Integrated Modeling and Interagency Crosscutting Group on Climate Change and Human Health, as well as the National Science and Technology Council’s Pandemic Prediction and Forecasting Science and Technology Working group. The report highlights key gaps and provides a summary of needed interagency actions ranging from research to forecast production—some of which have already started.

This special report from the Intergovernmental Panel on Climate change describes the impacts of global warming of 1.5 °C above pre-industrial levels. The report also describes potential global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.

As incomes rise and populations grow, especially in the world’s hotter regions, the use of air conditioners is becoming increasingly common. In fact, the use of air conditioners and electric fans already accounts for about a fifth of the total electricity in buildings around the world–or 10 percent of all global electricity consumption. Over the next three decades, the use of ACs is set to soar, becoming one of the top drivers of global electricity demand. This new analysis by the International Energy Agency shows how new standards can help the world avoid facing such a “cold crunch” by helping improve efficiency while also staying cool.

This report documents that the average temperature in 2015 was over one degree higher than pre-industrial times and that the period 2011–2015 was the warmest five-year period on record, consistent with established warming trends. The report further documents that in 2015 another milestone was reached, with globally averaged CO2 levels of 400 parts per million (ppm). The year 2016 is on track to be even warmer and will be the first year in which CO2 at the Mauna Loa Observatory remains above 400 ppm all year, and for many generations to come.

The probability of extreme climate events since 2011, especially those involving extreme high temperatures, has been substantially increased by climate change, often by a factor of 10 or more. The single most significant event in humanitarian terms, with over 250,000 lives lost, was the 2011–2012 famine in the Horn of Africa, where drought was a major factor.

This report promotes a relatively simple solution to the problem of increasing heat and air pollution in cities: plant more trees. Trees cool the air by casting shade and releasing water vapor, and their leaves can filter out fine particulate matter (PM)—one of the most dangerous forms of air pollution, generated from burning biomass and fossil fuels. 

The report documents analysis that tree planting efforts could improve the health of millions of people, and that trees are as cost-effective as many other common solutions. The report also shows that most of the cooling and filtering effects created by trees are fairly localized, so densely populated cities—as well as those with higher overall pollution levels—tend to see the highest overall return on investment (ROI) from tree plantings.

A 24-year tradition encompassing the work of 425 authors from 57 countries, 2013's State of the Climate report uses dozens of climate indicators to track patterns, changes, and trends of the global climate system.

Cover of the Reducing Climate-Sensitive Disease Risks report
Published
April 2014

This report focuses on livestock diseases that are sensitive to climate change. The report aims to help practitioners reduce the risks of key climate-sensitive infectious diseases by strengthening risk management systems for disease outbreaks. The three diseases chosen for the study—Rift Valley fever, Bluetongue, and East Coast fever—spread through “vectors” such as insects and parasites, the prevalence of which fluctuates depending on key weather and climate variables such as temperature and humidity. As the symptoms of climate change continue, the frequency and extent of these diseases are expected to escalate.
