Question 17GS3UNKNOWN
What are the reasons behind the increased frequency and intensity of heat waves globally? How will it impact global food security? (Answer in 250 words)
Introduction
Heat waves are defined as abnormally high temperatures as derivation of long term averages in plain, coastal & hilly regions.

Main Body
Reasons:
1[Increased Solarity]
2Global Warming: Clearly higher global temperature in all regions (1.5°C increase since 1850 - IPCC)
3[Climate Change]: Increasing average temperature over long periods & intensifying heatwaves (E3 Chennai 2023)
4Wildfires: Increasing & oddly carbon & soot to further increase Greenhouse effect. (E3 Hawaii, 2024, Italy)
5Lower Resilience: In human population increasing perception & intensity (E3 Diet-related on Costly System)
6[Increased Frequency]
7Human action: Creating unnecessary Greenhouse effect by adding GHG goes due to development & industrialisation (E3 Melbourne CO2)
8Urban Heat Island Effect: Creating more frequent heatwave. (E3 Concentration in New York)
9Heat dome: Region of high pressure & temperature inhibiting convection & cloud formation. (E3 Europe 2023)
4Wildfires: Increasing & oddly carbon & soot to further increase Greenhouse effect. (E3 Hawaii, 2024, Italy)
5Lower Resilience: In human population increasing perception & intensity (E3 Diet-related on Costly System)
[Increased Frequency]
6Human action: Creating unnecessary Greenhouse effect by adding GHGs goes due to development & industrialisation (E3 Melbourne CO2)
7Urban Heat Island Effect: Creating more frequent heatwave. (E3 Concentration in New York)
8Heat dome: Region of high pressure & temperature inhibiting convection & cloud formation. (E3 Europe 2023)
9Lower Monsoon Rain: due to El Niño conditions (Smart Food Security)
10[Crop losses]: due to high temp & wilting. (E3 Wheat in India (2023))
11High water Use: due to increased irrigation needs. (IASJ) (E3 Paddy)
12Lower Food Available: due to low production. (E3 Ghana, Bolivia)
13Great Pressure: on public food distribution. (India spent 2.3 lakh crore in Food Subsidy in 2022-23)
