Summary
Climate change significantly impacts health in India, causing heat wave mortality, respiratory illnesses, and malnutrition. Further research is needed to understand and mitigate these health risks, especially for vector-borne diseases.
Area of Science:
- Environmental Health
- Public Health
- Climate Science
Background:
- Climate change poses significant health risks in India, including mortality from heat waves and increased respiratory diseases.
- Impacts extend to malnutrition due to crop failures and increased disaster frequency like floods.
- Southeast Asia faces substantial disease burden, with over 2.5 million DALYs (Disability-Adjusted Life Years) estimated.
Purpose of the Study:
- To review the current understanding of climate change's health impacts in India.
- To identify knowledge gaps and uncertainties in existing research.
- To highlight the need for further studies on climate-sensitive diseases.
Main Methods:
- Literature review of climate change and health studies in the Indian context.
- Analysis of current research scenarios and identification of future research needs.
- Discussion of uncertainties and knowledge gaps in the field.
Main Results:
- Climate change contributes to heat wave mortality, respiratory diseases, flood-related disasters, and malnutrition.
- Specific concerns exist for diseases like dengue and chikungunya due to changing transmission dynamics.
- Vulnerable areas, including northeastern states, require targeted interventions for vector-borne diseases.
Conclusions:
- Urgent need for further research on climate change impacts on public health in India.
- Focus on vector-borne diseases like dengue and chikungunya is critical.
- Strategic interventions can minimize climate change risks, particularly in endemic and malaria-free regions.

01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
01:16What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
01:21Dimensions of Health and Illness
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
01:27Microbes and Climate Change
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

01:18Factors Affecting Illness
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...
