What Is Climate Change?
Climate change refers to long-term shifts in temperatures and weather patterns. For some years human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil, and gas.
Greenhouse gas emissions that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and forests can also release carbon dioxide. Landfills for garbage are a major source of methane emissions. Energy, industry, transport, buildings, agriculture, and land use are among the main emitters. Energy sources release a gas called carbon dioxide (CO2) into the atmosphere. When CO2 and other greenhouse gases trap heat that would otherwise escape Earth’s atmosphere, the planet’s temperature rises. That’s called global warming, which causes climate change.
People are experiencing climate change
Climate change can affect our health, raises disease skin diseases 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 nations and other developing countries. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate, and protracted droughts are putting people at risk of famine. In the future, the number of “climate refugees” is expected to rise.
There are many benefits to taking action on climate change, such as improved health, growth in the low-carbon jobs market, and reduced inequality. There are many benefits to taking action on climate change, such as improved health, growth in the low-carbon jobs market, and reduced inequality.
