Key scientific concerns about climate change are based on extensive evidence from observations, climate models, and multiple scientific disciplines studying Earth’s climate system. They include:
- RISING GLOBAL TEMPERATURES: Earth’s average temperature continues to increase due to greenhouse gas emissions from burning fossil fuels, deforestation, and industrial activity. Recent years have repeatedly set heat records, contributing to more intense heatwaves and ecosystem stress;
- SEA-LEVEL RISE: Sea-level rise is one of the most significant and visible consequences of climate change. As global temperatures increase, oceans warm and expand, while glaciers and ice sheets melt, adding more water to the seas. Rising sea levels increase the risk of coastal flooding, shoreline erosion, saltwater intrusion into freshwater resources, and damage to ecosystems such as wetlands and mangroves. They also threaten homes, infrastructure, and livelihoods in coastal communities around the world, especially for coastal regions.
