Changes in climate , specifically rising temperatures, altered precipitation patterns, and increasing concentrations of atmospheric carbon dioxide , are expected to contribute to increasing levels of some airborne allergens and associated increases in asthma episodes and other allergic illnesses [High Confidence].

Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

Climate change will also bring new diseases to many areas, including water-borne diseases like cholera. The whole region is relatively poor so will struggle to adapt. The first step is to adapt to the current climate. That includes easing poverty and creating early warning systems for disease outbreaks and bad weather.

Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air. Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world.

A changing climate thus affects the prerequisites of population health: clean air and water, sufficient food, natural constraints on infectious disease agents, and the adequacy and security of shelter. A warmer and more variable climate leads to higher levels of some air pollutants.

As Earth becomes warmer, its atmosphere can hold more water vapor, which amplifies the initial warming in a process called the “water vapor feedback.” Variations in carbon dioxide have therefore been the controlling influence on past climate changes.

Air pollutants have a complex relationship with climate change. Some pollutants, such as black carbon and ozone, increase warming by trapping heat in the atmosphere, while others, such as sulfur dioxide forming light reflecting particles, have a cooling effect on the climate.

Nitrogen emissions such as ammonia, nitrogen oxide and nitrous oxides contribute to particulate matter and acid rain. These cause respiratory problems and cancers for people and damage to forests and buildings. Nitrogenous gases also play an important role in global climate change.

According to the National Climate Assessment, climate change will affect human health by increasing ground-level ozone and/or particulate matter air pollution in some locations. ... The increase in air pollutants makes the effects of increased allergens associated with climate change even worse.

Pesticides and Climate Change With a longer growing season and a warmer climate, weeds and insect pests will proliferate, most likely leading to more pesticide use – which is itself responsible for harmful emissions that further exacerbate climate change.

In addition to increasing global temperatures, the impacts of climate change include extreme weather events such as drought, hurricanes and rising sea levels. ... In addition to increased rates of disease and degraded habitats, climate change is also causing changes in species themselves, which threaten their survival.

Climate change influences severe weather by causing longer droughts and higher temperatures in some regions and more intense deluges in others, say climate experts. Among the most vulnerable are communities in exposed mountain and coastal regions.

Climate change is affecting pollination by disrupting the synchronized timing of flower blooming and the timing at which bees pollinate. Flowers are blooming earlier in the growing season due to rising temperatures, before many bees have a chance at pollinating the plants[1], [2].

“Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there's more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and ...
