Climate Change Definition
Climate change can be a natural process where temperature, rainfall, wind, and other elements vary over decades or more. For millions of years, our world has been warmer and colder than it is now. But today we are experiencing rapid warming from human activities, primarily due to burning fossil fuels that generate greenhouse gas emissions.
Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas), which produces heat-trapping gases.
Climate Change Definition
- Increasing greenhouse gas emissions from human activity act like a blanket wrapped around the earth, trapping the sun’s heat and raising temperatures.
- People are experiencing climate change in diverse ways. It affects our health, ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island developing States. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate. In the future, the number of “climate refugees” is expected to rise.
- Every increase in global warming matters. In a 2018 report, thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate.
