Main Body

IPCC's Sixth Assessment Report has warned about the Indian Ocean warming at a decadal high level with 2019 recent highest temperature.

Causes of Indian Ocean warming:

Natural causes | Anthropogenic:

1El-Nino year after (1) Climate change due

3 triple dip (2) LaNina to Industrial Activity

(Paris climate agreement

2changing monsoon for 1.5°C already

Pattern breached by 2020)

3changing Ocean (2) Weakened Albedo

current (Agulhas, effect due to ice

equatorial current) melting (Himalayas)

patterns. 1&x more than ever.

It may affect food security in India

1On Agriculture:
Unstable Rainfall due to Ocean Warming (45% population Rainfed Agri.)
Threaten current crops food-water Lordshipextreme weather event triggered.
Increased gap [handwriting unclear]
2On Coastal Fisheries:
India 2nd largest producer, 8.9% global
Ocean warming - fish deaths & Reduced capacity of fish farming.
Impact due to increased Cyclones in Arabian Sea due to @°C temp
3On Seafood - like crabs, prawn.
Threaten tourism opportunity & crab & prawns culture in Goa.

Diagram

Diagram showing causes of Indian Ocean warming split into Natural causes (El-Nino, LaNina, changing monsoon pattern, changing Ocean currents) and Anthropogenic causes (Climate change, Weakened Albedo effect)

  • Cites IPCC Sixth Assessment Report as credible source
  • Uses diagram to clearly distinguish natural and anthropogenic causes
  • References relevant phenomena like El-Nino, LaNina, monsoon changes
  • Mentions Paris Climate Agreement with specific targets
  • Discusses albedo effect and ice melting mechanisms
  • Clearly addresses the question about food security impacts
  • Provides specific data (45% population on rainfed agriculture, 8.9% global fisheries)
  • Covers multiple dimensions: agriculture, fisheries, and seafood
  • Mentions specific locations like Goa
  • Links ocean warming to cyclones
  • Addresses tourism impact
