Pointing out that allergies are more severe today with climate change as a result of global warming, Assoc. Dr. Hikmet Tekin Nacaroğlu said, “Air pollution increases respiratory diseases. Global warming emerges with the increase in the rate of carbon dioxide, methane, nitrous oxide gases, chlorofluorocarbon and ozone and water vapor in the atmosphere as a result of the increase in the use of fossil fuels and population, the decrease of forests, urbanization and improper agricultural practices in parallel with the industrial revolution. These increased human activities are accelerating natural climate change, causing global climate change. With the intense use of fossil fuels such as oil, natural gas and coal with industrialization, the amount of toxic greenhouse gases increased in the atmosphere. In relation to the resulting air pollution, increases in the severity of respiratory diseases such as allergic rhinitis and asthma have occurred in the society ”.

“GLOBAL WARMING INCREASES POLEN EMISSIONS”

Stating that one of the most important allergens is pollen, Assoc. Dr. Nacaroğlu continued as follows:

“Pollens belonging to plants, most of which are pollinated by wind and which can cause respiratory allergies, and their concentrations in the air are largely affected by climate changes due to global warming. The effect of climate on pollination is based on long-term measurements and researches, and short-term changes occur under the influence of meteorological events. The amount of pollen in the air is influenced by meteorological factors such as temperature, wind speed, humidity, cloudiness and total rainfall.Generally, sunny days with high temperatures and moderate winds and rainfall are the periods when pollen release is highest.

“POLEN SEASON NOW BEGINS 20 DAYS AGO”

Assoc. Dr. Nacaroğlu pointed out that with the pollination time, the level and allergic characteristics of the pollens increase and gave the following information:

“With the recent studies, it has been shown that global warming and increasing carbon dioxide concentrations in the world have an effect on the beginning and end of pollination periods in some plants and pollen concentrations in the atmosphere. According to the data of a new study conducted in the USA, due to the effects of global warming since 1990, North America Pollen seasons have been shown to begin on average 20 days ago, causing an increase in pollen concentrations by 20 percent higher. The same researchers stated that they expect the pollen seasons to get worse in the coming years. Atlantic Oscillation (KAS) causes long-distance transport and early or late initiation of pollination by affecting the plants especially in early spring.KAS, in our country, blooms in the early spring period and has allergic importance such as hazelnut, alder, birch, ash tree. It causes early or late blooming of flowers in trees pollinated with zgar. “

“ASTHMA ATTACKS MAY BE MORE DIFFICULT EVERY YEAR”

Assoc. Dr. Nacaroğlu said, “As a result, the distribution of pollen in the air depends largely on the climate parameters. Effects of climate changes on pollen; It has been shown in studies that it increases the production of pollen, extends the spread of pollen and extends the excuse period, and increases the antigenic properties of pollen, causing more complaints in allergic patients. In addition, in thunderstorms and rainy weather, pollens are broken down by the effect of lightning and can reach the lower respiratory tract by turning into smaller antigen carriers. In this case, it should be kept in mind that severe asthma attacks can be triggered. “It is important to inform patients that the allergy season may be more difficult every year due to these effects of global warming.”
