Long-term changes in temperature and weather patterns are referred to as climate change. These changes may be organic, but since the 1800s, human activity has been the primary cause of climate change. This is primarily because burning fossil fuels, such as coal, oil, and gas, releases gases that trap heat. Global warming is included in “climate change,” but it also refers to a wider variety of changes that are taking place to our planet.
These include changes in flower/plant blooming seasons, dwindling mountain glaciers, accelerated ice melt in Greenland, Antarctica, and the Arctic, and rising sea levels. All of these are effects of warming, which is mostly brought on by people burning fossil fuels and releasing heat-trapping gases into the atmosphere. 

As the planet continues to warm, climate-induced migration is poised to become a global crisis. For the most vulnerable geographies—most prominently, low-lying island states—climate migration poses an immediate and existential threat. Without substantial adaptation, the lowest-lying island states are predicted to be uninhabitable by mid-century, necessitating wholesale migration and jeopardizing cultural identity, independence, and sovereignty.
