Climate change is emerging prominently in subcontinental countries such as India and Southeast Asia. Some of the most important expressions are as follows:

-Heightened Heatwaves: More frequent and intense heatwaves are posing a significant problem. These are causing increased mortality, heat stress illnesses, and reduced agricultural productivity.

This shifts the rainfall trend and leads to both droughts and extreme flooding elsewhere, disrupting agriculture, destroying infrastructure, and probably leading to water scarcity and heightened vulnerability to waterborne diseases.
This is associated with sea level rise as, along coastlines, sea levels have risen; this leads to increased coastal erosion, saltwater intrusion into sources of fresh, and communities have been displaced from the coastline.

-Glacier Melt: Glacier melting in the Himalayas and other mountain ranges is impacting the availability of water for millions downstream. This has implications for both water scarcity in dry seasons and increased flood risk in wet seasons.

-Increasing Extreme Weather Events: More frequent and intense cyclones, typhoons, and other extreme weather events have caused widespread destruction to infrastructure, livelihoods, and ecosystems.

Changes in temperature and rainfall patterns have an impact on crop yields, leading to food insecurity and economic losses for farmers.
The impacts are not evenly distributed and disproportionately affect vulnerable populations, such as low-income communities and marginalized groups.
