Climate change is already affecting the cardiorespiratory health of populations around the world, and these impacts are expected to increase. The present overview serves as a primer for respirologists who are concerned about how these profound environmental changes may affect their patients. The authors consider recent peer-reviewed literature with a focus on climate interactions with air pollution. They do not discuss in detail cardiorespiratory health effects for which the potential link to climate change is poorly understood. For example, pneumonia and influenza, which affect >500 million people per year, are not addressed, although clear seasonal variation suggests climate-related effects. Additionally, large global health impacts in low-resource countries, including migration precipitated by environmental change, are omitted. The major cardiorespiratory health impacts addressed are due to heat, air pollution and wildfires, shifts in allergens and infectious diseases along with respiratory impacts from flooding. Personal and societal choices about carbon use and fossil energy infrastructure should be informed by their impacts on health, and respirologists can play an important role in this discussion.

Abstract. Wildfires pose a significant risk to human livelihoods and are a substantial health hazard due to emissions of toxic smoke. Previous studies have shown that climate change, increasing atmospheric CO2, and human demographic dynamics can lead to substantially altered wildfire risk in the future, with fire activity increasing in some regions and decreasing in others. The present study re-examines these results from the perspective of air pollution risk, focussing on emissions of airborne particulate matter (PM2. 5), combining an existing ensemble of simulations using a coupled fire–dynamic vegetation model with current observation-based estimates of wildfire emissions and simulations with a chemical transport model. Currently, wildfire PM2. 5 emissions exceed those from anthropogenic sources in large parts of the world. We further analyse two extreme sets of future wildfire emissions in a socio-economic, demographic climate change context and compare them to anthropogenic emission scenarios reflecting current and ambitious air pollution legislation. In most regions of the world, ambitious reductions of anthropogenic air pollutant emissions have the potential to limit mean annual pollutant PM2. 5 levels to comply with World Health Organization (WHO) air quality guidelines for PM2. 5. Worst-case future wildfire emissions are not likely to interfere with these annual goals, largely due to fire seasonality, as well as a tendency of wildfire sources to be situated in areas of intermediate population density, as opposed to anthropogenic sources that tend to be highest at the highest population densities. However, during the high-fire season, we find many regions where future PM2. 5 pollution levels can reach dangerous levels even for a scenario of aggressive reduction of anthropogenic emissions.

Efforts to mitigate air pollution and noise are a complex endeavour as they involve addressing their sources, which vary depending on the country and region of the world and complex economic and geopolitical considerations. Measures such as mandatory or voluntary greenhouse emissions or fuel efficiency standards, shifting to lower-carbon fuels, legislating the use of motorized vehicles/kilometres driven, introduction of electric mass transit, congestion pricing/taxes, vehicle and fuel taxes, and advanced vehicle technologies (e.g. battery electric cars, hybrids, plug-in hybrids, and fuel cell cars) may help simultaneously alleviate air and noise pollution and climate change goals.

The chapter and the Mali field research it is based on reveal how Muslim subjects in Mali encounter climate change and respond to it with a fascinating and creative blend of religious and political ideas. Ethnographic anecdotes relate the environmental changes that people in Ouélessébougou have confronted during their lifetimes and illustrate how residents dealt with the causes of climate change. In southern Mali, residents’ religious beliefs and practices played a central role in their interpretations of climate change and their criticisms of the moral state of the world in their blend of politics, religion, and ethics to assess causality and find meaning in chronic, climate-change-related drought.

<p>Climate changes are rapidly intensifying and can lead to adverse global health impacts. Indigenous populations are especially vulnerable to climate change because of their dependence on the environment for cultural activities and subsistence. The voices of Inuit Elders and seniors encompass deep wisdom and history; as such, the goal of this research was to examine the perceived impacts of climate and environmental changes on physical, mental, and emotional health, as observed by Elders and seniors in the Inuit community of Rigolet, Nunatsiavut, Labrador, Canada. A mixed-methods approach was used to gather data capturing these local observations, as well as perceived impacts on community health. A community survey was administered in November 2009 (n = 75) and in-depth interviews were conducted with Elders and seniors from January to October 2010 (n = 22). Survey results indicated that Elders and seniors observing changes in weather patterns, water systems, and wildlife were more likely to perceive climate change impacts on health (p &lt; 0.05). Emergent themes from the interviews included: recurring observations of climate change, including changes in temperature, ice, snow, and seasonal timing; impacts on physical health, including reduced physical activity levels and poorer nutrition; impacts on mental and emotional health, including feelings of isolation and depression; and an identified need for community-wide adaptation. This research emphasized the importance of understanding Elder-specific perspectives of climate-health relationships in the Canadian North to develop sustainable, culturally relevant adaptation strategies to mitigate health impacts related to climate change.<br /><br />ᓯᓚᐅᑉ  ᐊᓯᔾᔨᐸᓪᓕᐊᓂᖓ  ᓱᒃᑲᓕᔪᒃᑯᑦ  ᐱᕙᓪᓕᐊᕗᖅ  ᐊᒻᒪᓗ  ᓯᓚᕐᔪᐊᕐᒥ  ᐊᑦᑕᓇᖅᑐᒃᑯᑦ  ᐊᑦᑐᐃᔪᓐᓇᖅᑯᖅ  ᐃᓗᓯᓕᕆᓂᒃᑯᑎᒍᑦ.  ᓯᓚᕐᔪᐊᕐᒥ  ᓄᓇᖃᖅᑳᖅᑑᔪᑦ  ᐊᑦᑐᖅᑕᐅᓂᖅᐹᖑᔪᓐᓇᖅᑯᑦ  ᐊᕙᑎᒥᓂᒃ  ᑕᑎᖃᕐᓂᕐᒥᓄᑦ,  ᐱᖅᑯᓯᖏᑎᒍᑦ  ᐊᒻᒪᓗ  ᐱᓇᓱᐊᖅᐸᓐᓂᖏᑎᒍᑦ.  ᐃᓄᐃᑦ  ᐃᓐᓇᐃᑦ  ᐃᓐᓇᑐᖃᐃᓪᓗ  ᓂᐱᖏᑦ  ᓯᓚᑐᓂᕐᒥᒃ  ᑐᓐᖓᕕᖃᖅᑯᑦ  ᐊᒻᒪᓗ  ᐊᑐᖅᓯᒪᔭᖃᖅᑯᑦ;  ᓲᕐᓗ  ᐆᒧᖓ  ᖃᐅᔨᓴᕐᓂᕐᒧᑦ  ᑐᕌᒐᖃᖅᑎᓪᓗᒍ  ᓯᓚᐅᑉ  ᐊᓯᔾᔨᐸᓪᓕᐊᓂᖓᓂᒃ  ᐊᑦᑐᐃᔾᔪᑕᐅᔪᓂᒃ  ᐊᒻᒪᓗ  ᖃᓄᖅ  ᐊᕙᑎᐅᑉ  ᑕᐅᑦᑐᖓ,  ᐃᓱᒪᒃᑯᑦ  ᐊᒻᒪᓗ  ᐃᓗᓯᓕᕆᓂᒃᑯᑎᒍᑦ,  ᐃᓐᓇᐃᑦ  ᑕᑯᓐᓇᖅᑕᖃᖅᑯᑦ  ᐃᓄᐃᑦ  ᓄᓇᓕᖓᓂ  ᕆᒍᓚᑦ,  ᓄᓇᑦᓯᐊᕗᒻᒥ,  ᓛᐸᑐᐊᒥ,  ᑲᓇᑕᒥ.  ᑲᑎᑕᐹᓂᑦ  ᖃᐅᔨᓴᕐᓂᕐᒧᑦ  ᐊᖅᑯᑏᑦ  ᓄᓇᓕᒻᒥ  ᑕᑯᓐᓇᒐᐅᕗᑦ  ᐊᒻᒪᓗ  ᑕᑯᓐᓇᑕᒃᑯᑦ  ᓄᓇᓕᒻᒥ  ᐃᓗᓯᓕᕆᓂᒃᑯᑦ  ᐊᑦᑐᖅᑕᐅᓂᐅᔪᑦ.  ᓄᓇᓕᒻᒥ  ᐊᐱᖅᓲᑎ  ᓄᕕᐱᕆ  2009<strong>−</strong>ᒥ  ᐃᖏᕐᕋᓂᖃᔪᕗᖅ  (<em>n </em>= 75)  ᐊᒻᒪᓗ  ᐃᓗᑐᔪᓂᑦ  ᐊᐱᖅᓲᑎᖃᔪᕗᑦ  ᐃᓐᓇᕐᓄᑦ  ᐃᓄᑐᖃᕐᓄᓪᓗ  ᔮᓐᓄᐊᓕᒻᒥᑦ  ᐅᑐᐱᕆᒧᑦ  2010<strong>−</strong>ᒥ (<em>n </em>= 22). ᐊᐱᖅᓲᑎᒧᑦ  ᑭᒡᒍᓯᐅᔪᔪᑦ  ᓇᓗᓇᐃᖅᓯᔪᕗᑦ  ᐃᓄᑐᖃᐃᑦ  ᑕᑯᔭᖃᖅᓯᒪᓂᖏᓐᓂᒃ  ᓯᓚᐅᑉ  ᖃᓄᐃᓐᓂᖓᑕ  ᐊᓯᔾᔨᕐᓂᖏᓐᓂᑦ,  ᐃᒪᐅᓪᓗ  ᐊᒻᒪᓗ  ᐆᒪᔪᐃᑦ  ᑕᒪᒃᑯᐊ  ᐊᑦᑐᐃᔪᑦ  ᐃᓄᐃᑦ  ᐃᓗᓯᕆᔭᖏᓐᓂᒃ  (<em>p </em>&lt; 0.05).  ᓲᔪᕐᓇᑐᓪᓗ  ᐊᓚᒃᑲᔪᔪᑦ  ᐊᐱᖅᓲᑕᐅᔪᔪᓂᑦ  ᐃᓗᓕᖃᐅᕐᓂᖓᓄᑦ  ᒪᑯᓂᖓ:  ᓲᔪᕆᔭᐅᕙᑦᑐᑦ  ᓯᓚᐅᑉ  ᐊᓯᔾᔨᕐᓂᖓᓄᑦ;  ᓂᓪᓚᓱᓐᓂᕐᒧᑦ  ᐆᖅᑰᓇᕐᓂᒧᓪᓗ;  ᓂᓚᐅᑉ,  ᐊᐳᑎᐅᑉ  ᐊᒻᒪᓗ  ᐅᐱᕐᖔᑉ,  ᐅᑭᐅᑉ  ᐊᓰᓐᓇᓕᓂᖏᓐᓂᒃ; ᐊᑦᑐᐃᔾᔪᑕᐅᔪᓪᓗᑎ  ᑎᒥᒧᑦ   ᐃᓗᓯᓕᕆᓂᕐᒧᑦ;  ᐃᓱᒪᒧᑦ  ᐊᒻᒪᓗ  ᐃᓱᒪᒃᑯᑦ  ᐃᓗᓯᓕᕆᓂᕐᒨᖓᔪᑦ,  ᐃᓚᓕᐅᑦᑐᒋᑦ  ᐃᑉᐱᓐᓂᐊᔾᔪᑎᑦ  ᐃᓄᑑᓕᐅᑎᓂᕐᒧᑦ  ᐊᒻᒪᓗ  ᓄᒫᓱᓐᓂᒃᑯᑦ  ᐊᒻᒪᓗ;  ᑭᓐᖒᒪᑦᑎᓂᖅᓄᓇᓕᒻᒥ  ᐊᓯᔾᔨᐸᓪᓕᐊᓂᕐᒧᑦ  ᖃᓄᖅᑑᕈᑎᓂᒃ.  ᐅᓇ  ᖃᐅᔨᓴᕐᓂᖅ  ᓇᓗᓇᐃᖅᓯᓚᐅᖅᑯᖅ  ᐱᓪᓗᕆᑦᑐᓂᒃ  ᑐᑭᓯᐅᒪᔾᔪᑎᓂᒃ  ᐃᓐᓇᕐᓄᑦ  ᐃᓱᒪᒋᔾᔪᑕᐅᓯᒪᔪᓂᒃ  ᓯᓚᐅᑉ  ᐊᓯᔾᔨᐸᓪᓕᐊᓂᖓᓄᑦ  ᐃᓗᓯᓕᕆᓂᕐᒧᑦ  ᐊᑦᑐᐊᓂᖃᖅᑎᓪᓗᒋᑦ  ᑲᓇᑕᐅᑉ  ᐅᑭᐅᖅᑕᖅᑐᖓᓂ  ᑐᕌᒐᖃᕐᓂᐊᑎᓪᓗᒋᑦ  ᑲᔪᓯᐅᒪᔾᔪᑎᔅᓴᓂᒃ,  ᐱᖅᑯᓯᖅᑎᒍᑦ  ᐊᑲᕐᕆᔪᓂᒃ  ᐅᐸᓗᖓᐃᔭᕈᑎᓂᒃ  ᐊᑦᑐᖅᑕᐅᓂᑭᓐᓂᖅᓴᐅᖁᓪᓗᒋᑦ  ᐃᓗᓯᓕᕆᓂᒃᑯᑦ  ᐃᑉᐱᓐᓂᕈᑎᓂᒃ  ᓯᓚ  ᐊᓯᔾᔨᐸᓪᓕᐊᑎᓪᓗᒍ.</p>

Environmental pollution has become a problem not only for one nation, one region but also for the common concern of all humanity. The process of socio-economic development of the countries in the world has led to tremendous impacts on the environment, causing the human environment to change and become increasingly degraded. important. These are climate change - global warming, depletion of the ozone layer and acid rain ... especially air pollution caused by transportation. In Vietnam, environmental pollution in big cities is becoming a pressing problem. The problem of overcrowding of transport in big cities, which has been very difficult, now adds a serious situation of pollution that is increasing to worrying levels. What a challenging problem that is posing on the shoulders of managers. The paper presents the realities of environmental pollution, especially air pollution from vehicle emissions. Besides, also initially offering solutions to reduce pollution caused by urban transport in Vietnam.

Lichens have been used as biomonitors for multiple purposes. They are well-known as air pollution indicators around urban and industrial centers. More recently, several attempts have been made to use lichens as monitors of climate change especially in alpine and polar regions. In this paper, we review the value of saxicolous lichens for monitoring environmental changes in Antarctic regions. The pristine Antarctica offers a unique opportunity to study the effects of climate change along a latitudinal gradient that extends between 62° and 87° S. Both lichen species diversity and thallus growth rate seem to show significant correlations to mean annual temperature for gradients across the continent as well as to short time climate oscillation in the Antarctic Peninsula. Competition interactions appear to be small so that individual thalli develop in balance with environmental conditions and, as a result, can indicate the trends in productivity for discrete time intervals over long periods of time.

Air pollution is the natural processes caused by human activities through which certain substances enter the atmosphere at a sufficient concentration to cause environmental pollution. The World Health Organization reported that 80% of the world's cases of heart disease and stroke deaths were due to air pollution, and a total of 7 million people in the world died of air pollution in 2012. Unplanned urbanization, industrialization, and agricultural activities contribute to air pollution. Climate change affects air pollution in a number of factors including changes in temperature, solar radiation, humidity, precipitation, atmospheric transport, and biogenic emissions. Increasing scientific evidence shows that air pollution and climate change policies must be integrated to achieve sustainable development and a low carbon (LC) society. Combined efforts to deal with air pollution and climate issues at the urban level will be particularly important as most people are exposed to air pollution, and 75% of global GHG emissions are generated in urban areas.
