Global temperatures have increased by about 1.1°C (2°F) over pre-industrial levels, and this development is anticipated to grow in the ensuing decades. In the last decade of the century, the IPCC predicts that global temperatures may have risen by up to 3-5°C (5.4-9°F), which would have a considerable impact on weather patterns, sea levels, floods, food security, and human health. Millions of people might be forced to relocate due to rising sea levels, especially those residing in low-lying coastal regions and tiny island nations. The argument over whether the terms "climate refugee" or "environment refugee" accurately depict those who flee their homes because of climate-related problems or natural catastrophes. The international community has to be ready for communities and civilizations being uprooted owing to climate change.
