Understanding the 1.5°C Climate Target and Its Impact on India

Understanding the 1.5°C Target and Its Significance for India

The 1.5°C target is a key goal established in the 2015 Paris Agreement, aiming to limit global warming to well below 2°C and preferably to 1.5°C above pre-industrial levels. This target is crucial for mitigating the impacts of climate change, such as extreme weather events, rising sea levels, and disruptions to ecosystems and agriculture.

Why is the 1.5°C Target Crucial for India?

India is particularly susceptible to climate change due to its diverse geography, vast population, and reliance on climate-sensitive sectors like agriculture. The potential consequences of exceeding the 1.5°C threshold are alarming:

• Intensified heatwaves: More frequent and severe heatwaves can cause heat stress, water scarcity, and negatively affect public health and agricultural productivity.
• Disruptions in monsoon patterns: Changes in monsoon rainfall can lead to flooding in some areas and droughts in others, jeopardizing food security and livelihoods.
• Rising sea levels: Coastal cities, including major hubs like Mumbai and Chennai, face significant risks from rising sea levels, saltwater intrusion, and increased storm surges.
• Himalayan glacial retreat: The melting of glaciers threatens freshwater supplies for millions, impacting irrigation, hydropower generation, and river ecosystems.

The Debate Over Continuing Focus

There is ongoing debate about whether the 1.5°C target should remain the focal point of climate action. Some critics argue that it is unrealistic given current emissions trends, while others believe that it diverts attention from necessary adaptation efforts already needed due to climate impacts.

Alternative Viewpoints for India

Several alternative strategies suggest a broader focus:

• Local risk assessment and adaptation: Emphasizing the importance of understanding and preparing for climate impacts on a regional and city level. This includes investments in heat action plans, drought-resistant crops, early warning systems, and coastal protection measures.
• Focus on shorter-term targets: While long-term goals are vital, prioritizing immediate emissions reductions and adaptation strategies is crucial for managing climate risks in the coming decades.

India's Current Actions

In response to these challenges, India has set ambitious renewable energy targets and aims to achieve net-zero emissions by 2070. However, reaching these goals will necessitate significant investments in clean energy infrastructure and technological advancements.

Examples of Impacts Already Felt in India

India has already experienced various climate-related impacts, including:

• Heatwaves: Record-breaking heatwaves in several regions have resulted in deaths, power outages, and disruptions in agriculture.
• Floods and droughts: Erratic monsoon patterns have caused severe flooding in some areas and droughts in others, significantly affecting agricultural production and livelihoods.
• Glacial retreat: The retreat of Himalayan glaciers poses a serious threat to water supplies for millions in the Indo-Gangetic plains.

What's the Alternative Viewpoint to a Singular Focus on 1.5°C?

Focusing on local risk assessment allows for tailored strategies that prepare for climate impacts at a regional level. Additionally, setting shorter-term targets can help address immediate climate risks rather than solely focusing on long-term goals.

Temporary vs. Permanent Breach

The significance of the temporary breach of 1.5°C in 2023 highlights the ongoing trend of rising temperatures, partly driven by natural climate cycles such as El Niño. However, this is not indicative of a permanent breach expected as part of long-term global warming trends.

Can Individual Weather Events Be Directly Blamed on Global Warming?

While climate change increases the likelihood of certain extreme events, scientists use attribution studies to determine whether warming has significantly influenced specific occurrences.

Looking Ahead

The 1.5°C target remains a vital reference point for global climate action, particularly for India's future efforts. Regardless of the exact temperature rise, prioritizing adaptation strategies and building resilience will be critical for India to effectively manage the unavoidable impacts of climate change.
