A 498 references paper on climate change and allergy

This is certainly the most comprehensive paper that examines the association of air pollution, climate change and allergen exposure: “Air Pollution and Climate Change Effects on Allergies in the Anthropocene: Abundance, Interaction, and Modification of Allergens and Adjuvants

Air pollution and climate change are potential drivers for the increasing burden of allergic diseases. The molecular mechanisms by which air pollutants and climate parameters may influence allergic diseases, however, are complex and elusive.

There is no causal effect of allergens on human allergy, as allergens have been always abundant even without allergy. Nevertheless allergens are drivers aggravating symptoms in allergy-prone patients by basically four factors

  1. Stability effects; influencing the accumulation and degradation of allergenic proteins, the duration of exposure times to cellular receptors, and the process of antigen presentation via major histocompatibility complex (MHC) class II
  2. Epitope effects, i.e., generation of new epitopes or modification of existing epitopes, changing the binding properties of antibodies and receptors, by direct chemical modification or as a result of conformational changes
  3. Adjuvant effects, i.e., generation of new adjuvant functions or modification of existing adjuvant functions such as lipid-binding capacities due to modified ligand binding sites
  4. Agglomeration effects, i.e., multiplication or shielding of epitopes or adjuvant functions by cross-linking (oligomerization) of allergenic proteins, which may enhance the cross-linking

I would add 5. that the absolute number of pollens increased in some areas as a stress response of dying trees.

Scientists who change their life style

There are scientists who support climate campaigns but there are also scientists who change their life style.

Kim Cobb traveled to the Kiritimati coral reefs in the spring of 2016 and found, to her horror, an underwater graveyard.
A climate scientist at the Georgia Institute of Technology, Cobb was alarmed to see this precious research site in the Pacific Ocean in such visible distress. The reefs were mostly dead after months of being in abnormally warm ocean waters […]
And so, she underwent a “wholesale reorganization” of her life, she said, including biking to work, rarely flying, going vegetarian, investing in expensive residential rooftop solar panels, and getting involved in her community’s new transportation plans.
