Climate Change Impacts in Asia: A Special Edition

This report details the escalating impacts of climate change, particularly focusing on Asia, which is experiencing warming at nearly twice the global average. The year 2025 is highlighted as a period of unprecedented heat, leading to the adoption of the term "global boiling." The World Meteorological Organization (WMO) has identified Asia as a critical region facing amplified climate risks.

Mitigation and Adaptation Strategies

Dr. Hijoka Yasuaki, a leading climate change expert from Japan's National Institute for Environmental Studies, outlines two primary strategies for addressing climate change:

• Mitigation: This involves reducing greenhouse gas emissions into the atmosphere or enhancing the capacity of carbon sinks (natural reservoirs that absorb carbon dioxide) to absorb them.
• Adaptation: This refers to actions taken to reduce or avoid the negative impacts of climate change while also identifying and leveraging potential opportunities. Dr. Hijoka emphasizes that adaptation must be applied to people's lives and lead to concrete actions. His institution promotes adaptation through social media campaigns like "#let's adapt," offering practical advice for daily life.

The State of Climate in Asia: WMO Report 2024

A WMO report on the state of the climate in Asia in 2024 revealed alarming trends:

• Accelerated Warming: Asia's average temperature has increased by 1.04°C compared to the 1991-2020 baseline, which is double the global average rate of increase.
• Record High Sea Surface Temperatures: Over the past decade, sea surface temperatures in Asia have risen by 0.24°C, also approximately twice the global rate. This has led to unprecedented marine heatwaves.
• Extreme Weather Events:
  • China: Experienced its highest temperatures in 70 years.
  • Indonesia: Faced thousands of hectares of drought.
  • India: Saw 1.65 million people affected by flood damages.
  • Pakistan: Glacial flooding forced the evacuation of thousands.
  • United Arab Emirates: Recorded its largest rainstorm since 1949, with 259.5 mm of rain in 24 hours, more than double the annual average.
  • Inland China: Suffered an extreme drought affecting 4.76 million people and over 330,000 hectares of farmland, with economic losses exceeding $400 million.

Impacts on the Cryosphere and Glacial Lakes

• Glacial Melting: The mountainous region between the Tibetan Plateau and the Himalayas, a significant part of the cryosphere, is experiencing intense warming and reduced winter snowfall, leading to large-scale glacial melting. Out of 24 surveyed glacial locations, 23 showed reductions in volume.
• Glacial Lake Collapse: In Sikkim, India, melting glaciers caused glacial lakes to collapse, resulting in over 100 deaths and missing persons, and damages to around 90,000 people.

The Role of Human Activity

The Intergovernmental Panel on Climate Change (IPCC) in its Sixth Assessment Report stated with "no doubt" that human activities are a significant factor in climate change. The emission of greenhouse gases like carbon dioxide from human activities traps heat, leading to rising air and sea temperatures.

Geographical Factors Contributing to Asia's Rapid Warming

Dr. Hijoka explains that Asia's vast inland areas are less exposed to the moderating effect of sea breezes. Furthermore, rapid urbanization and socio-economic development have intensified the "urban heat island effect," creating hotter environments.

Case Study: Indonesia's Mega Fires and Peatland Issues

• Vulnerability: With 48% of its land area covered by forests, Indonesia is highly susceptible to wildfires.
• 2019 Fires: Major fires in Kalimantan and Sumatra in June 2019 consumed 3.1 million hectares of land over nearly six months.
• Peatland Fires: Peatlands, which constitute 11% of Indonesia's surface area, are a significant fire risk. These waterlogged soils become highly flammable when dry, allowing fires to burn underground and persist for extended periods.
• Health Impacts: The smoke from these fires is toxic. In 2019 alone, over 900,000 people in Indonesia received hospital treatment for pollution-related respiratory issues. Dr. Faber Christian Monty, a pulmonologist, witnessed the severe health consequences.
• Carbon Sequestration Loss: Peatlands are crucial carbon sinks, storing more carbon dioxide than forests. Their destruction not only releases stored carbon but also eliminates future sequestration capacity. Preventing these fires falls under mitigation efforts.
• Global Significance: Indonesia's peatlands, covering approximately 26.55 million hectares (about 14% of the country's land), represent about 4.6% of the world's total peatland area, making their protection globally important.

Case Study: Dengue Fever Outbreaks in Asia

• Global Increase: Dengue fever cases have surged globally, with the World Health Organization recording approximately 14.6 million cases in 2024, a nearly 30-fold increase compared to 20 years prior.
• Vector Expansion: The yellow fever mosquito, the primary carrier of dengue, is expanding its range beyond tropical and subtropical climates due to temperature variations.
• Asia's Burden: The Philippines experienced a record high in dengue fever cases in 2024, with over 1,000 deaths. Hospitals in Manila saw a daily influx of new patients.
• Adaptation Measures:
  • Hospital Response: Hospitals have opened dedicated dengue fever wards.
  • Mosquito Control: Efforts focus on reducing mosquito populations by eliminating breeding sites, such as stagnant water.
  • Technological Solutions: Soda Technology, a Japanese startup, utilizes drones and AI to identify potential mosquito breeding grounds by analyzing aerial imagery for water bodies and their characteristics. This technology has also been deployed in Africa to combat malaria.

International Cooperation and Japanese Initiatives

• Global Cooperation: The transboundary nature of mosquito-borne diseases underscores the importance of international cooperation.
• Asia Zero Emission Community (AZEC): Launched in 2023 by the Japanese government, AZEC comprises 11 Asian countries working collaboratively on climate change countermeasures, including a 10-year plan for carbon neutrality and net zero.
• Private Sector Innovation: Japanese companies are developing innovative solutions. Shyabondama Soap has created an eco-friendly fire extinguishing agent based on natural ingredients, which proved effective in combating Indonesian mega fires, using significantly less water and promoting faster regrowth. This project received a subsidy from the Japanese Ministry of Economy, Trade, and Industry.

Net Zero and Technological Advancement

• Definition: Net zero emissions are achieved by offsetting greenhouse gas emissions through absorption via afforestation and conservation efforts.
• Japan's Approach: Japan aims to advance innovation by providing low-carbon technologies through public-private collaboration, focusing on renewable energy and hydrogen utilization.

Rising Sea Levels and Their Impact on Asia

• Global Trend: The IPCC reported a global average sea level rise of 20 cm between 1901 and 2018, with a notable acceleration in the last two decades.
• Asia's Vulnerability: Six observed areas in Asia have experienced sea level rise exceeding the global average of 3.4 mm per year.
  • Bangladesh: Has lost over 66,000 hectares of land to rising sea levels since 1967, forcing 50,000 to 200,000 people to relocate annually.
  • Vietnam: The Mekong Delta, a vital rice-growing region, is experiencing saltwater intrusion upstream due to rising sea levels, rendering land unsuitable for rice cultivation and forcing a shift to shrimp aquaculture.
• Causes of Sea Level Rise:
  • Thermal Expansion: Warming seawater expands in volume (0.025% increase per 1°C rise).
  • Melting Ice: Melting glaciers and ice sheets at the poles and in mountainous regions contribute significant water to the oceans.
• Future Projections: The IPCC has projected potential sea level rises of up to 1 meter by 2100 under worst-case scenarios. By 2050, cities like Shanghai are at high risk of significant submersion.
• Adaptation in Vietnam: Relocating rice cultivation inland is a potential adaptation strategy, but it involves securing land and relocating communities, posing significant challenges.

Extreme Rainfall and Flood Management

• Increased Intensity: Rising sea temperatures are impacting regional weather patterns, leading to more intense and unpredictable rainfall events.
• Examples:
  • Japan (Kyushu): Experienced heavy rains and landslides in August 2025 due to linear rainbands.
  • Pakistan: Faced exceptionally heavy monsoon rains from June to August 2025, 73% higher than the previous year, causing over 300 deaths.
  • Thailand: Has seen increasingly severe seasonal rains. The 2011 floods, unprecedented in 50 years, inundated industrial areas, causing worldwide production halts, particularly for Japanese-owned companies in the electronics and automotive sectors. The floods affected 2.3 million people and caused an estimated $4 billion in economic losses.
• Flood Prediction Systems: Thailand's Geo-Informatics and Space Technology Development Agency (GISTDA), in collaboration with the UN Satellite Centre, is developing a flood prediction system using satellite data and AI to provide early warnings to residents via a mobile app.

The Future of Climate Action in Asia

• AI and Data Utilization: AI is accelerating the analysis of climate data, improving predictive accuracy for weather events.
• Infrastructure Development: Direct satellite-to-smartphone communication services are being established to overcome underdeveloped terrestrial communication infrastructure in remote areas.
• Leveraging Strengths: Asia's young population and high smartphone penetration can be leveraged for effective adaptation strategies.
• Unified Approach: Despite geographical and cultural diversity, Asian nations share the common challenge of climate change impacts. A collective approach to setting and achieving climate goals is crucial.
• Personal Responsibility: Dr. Hijoka concludes by emphasizing that climate change is not a distant threat but a present challenge requiring immediate action from individuals in both mitigation and adaptation efforts.
