Climate Change

Passage

Climate change refers to long-term shifts in temperature, precipitation, and other atmospheric conditions on Earth. Over the past century, human activities, particularly the burning of fossil fuels, deforestation, and industrial activities, have contributed to the rise in greenhouse gases like carbon dioxide. These gases trap heat in the Earth's atmosphere, leading to global warming. The impacts of climate change are already being felt, including rising sea levels, more frequent and severe weather events such as hurricanes, droughts, and heatwaves, and shifts in ecosystems. The scientific consensus is that immediate action is needed to mitigate further damage, including reducing emissions, transitioning to renewable energy sources, and adopting sustainable practices in agriculture, transportation, and other industries.
