Environmental Factors: Consequences of Climate Change

Agriculture

  • In southern countries, crop yields are lower than a few years ago.

People and diseases

Respiratory system

  • Increase in warm climate
    • This will significantly extend the hay fever season (rhinitis allergica).The reason is clear: some pollen will fly earlier – others will fly well into October.In France and Italy, ragweed allergies have already become a massive problem. The ragweed plant (ragweed; mugwort ambrosia) can trigger respiratory distress and asthma during the flowering period from mid-July to mid-October. Touching the plant can also cause pruritus and redness of the skin. Notice: Meanwhile, the the plant is also in Germany. The plant can be found on roadsides or in private gardens.
    • During the pollen season increase in asthma attacks; as well as increase acute bronchospasms after a storm during the pollen season.
  • Severe exposure to harmful environmental factors such as traffic-related (nitrogen oxides, particulate matter) and secondarily formed air pollutants.
    • Increase in ozone levelsThis leads to: irritation of the mucous membranes, inflammatory reactions of the respiratory tract with impairment of lung function and physical performance.Affected: patients with bronchial asthma.

Skin and subcutaneous (L00-L99).

  • Atopic dermatitis (neurodermatitis) due to strong exposure of harmful environmental influences such as traffic-related (nitrogen oxides, particulate matter) and secondary formed air pollutants (ozone).

Infectious and parasitic diseases.

  • Mild winters and the heat after long periods of rain create ideal conditions for mosquitoes and ticks. Therefore, a greatly increased risk of Lyme disease (Lyme disease) and early summer meningoencephalitis can be assumed.
  • Further spread of the sheep tick. It spreads the so-called Q fever, which behaves similarly to summer flu. This disease manifests itself with fever, chills, faintness and headache and aching limbs. In about five percent of cases, the infected get pneumonia (pneumonia) or hepatitis (liver inflammation).
  • The in rare cases fatal West Nile virus infection is discussed in connection with climate change as a possible new infectious disease (West Nile fever) in Europe.
  • Tropical insects are increasingly making their way to Europe. Possibly come this way tropical diseases to us such as: Dengue fever, malaria, leishmaniasis, etc. The Bernhard Nocht Institute for Tropical Medicine estimates that dengue fever (transmitted by the Asian tiger mosquito (Stegomyia albopicta, formerly Aedes albopictus)) threatens approximately 2.5 billion people.The Asian tiger mosquito has also been present in Germany since 2007 as an invasive neozoon. Neozoon refers to species that have become established with human influence in an area where they were not previously native. It is to be expected, for example, that as temperatures rise, malaria will spread to regions that were previously too cool for the carriers of the disease, the Anopheles mosquitoes. The Bernhard Nocht Institute for Tropical Medicine estimates that approximately 2.4 billion people are at risk. Leishmaniasis, a tropical disease caused by parasitic protozoa (single-celled organisms), has now arrived in southern France. The vector is the sand fly. This has already arrived in Baden-Württemberg.
  • Increase in zoonoses (animal diseases), which are diseases caused by pathogens that mainly infect animals, but can be transmitted to humans at any time. These diseases include: Hanta virus infections (Bavaria and Baden-Württemberg are already affected; the disease can lead to kidney failure (Hantavirus in Germany; vector: deer mice); first symptoms of a Sin Nombre Hanta virus infection (visitors to Yosemite National Park, USA) are: Fatigue, fever, and muscle aches; in addition, cephalgia (headache), vertigo (dizziness), chills, vomiting, diarrhea, and abdominal pain (abdominal pain) may occur; 4-10 days after the initial illness phase, additional symptoms may include: Cough, dyspnea, and increasing respiratory distress (hantavirus-induced pulmonary syndrome, HPS; lethality (mortality related to the total number of people with the disease): 30-40 percent! ), leptospirosis, and tularemia (rabbit plague). These diseases take their origin in rodent populations.
  • Rise in water temperatures of the North and Baltic Seas: increase in wound infections caused by Vibrio vulnificus (a distant relative of the cholera pathogen).
  • Increase in salmonellosis due to increase in ambient temperature. From an ambient temperature of 5 °C, the incidence (rate of new cases) increases by 5-10% per °C of weekly increase in temperature.

Diveres

  • More heat deaths in young children, the elderly and the sick.Causes of death: Myocardial infarction (heart attack), cardiovascular disease, kidney disease and respiratory and metabolic disorders.Affected: people with chronic respiratory and cardiovascular diseases.

People, animals and buildings

  • Natural disasters (floods, storms) seem to occur more frequently. The influence of humans on climate change has been corroborated by researchers from the Canadian Centre for Climate Modelling in a scientific study. Parameters such as ground temperature, sea level pressure, temperature of the Earth’s atmosphere and oceans served as the basis of this study.
