What Is Climate Change? - Science@NASA
What Is Climate Change? Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
Climate change - Wikipedia
Present-day climate change includes both global warming —the ongoing increase in global average temperature —and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate.

Climate change - World Health Organization (WHO)
Research shows that 3.6 billion people already live in areas highly susceptible to climate change. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from undernutrition, malaria, diarrhoea and heat stress alone.
Climate Change - National Geographic Society
Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present.
Understanding Climate Change: Causes, Impacts, and Potential Solutions
Understanding climate change requires examining the intricate systems that govern the planet’s climate. The atmosphere, oceans, land surfaces, ice sheets, forests, and living organisms all interact in complex ways to regulate temperature and weather patterns.
Climate change impacts - National Oceanic and Atmospheric Administration
Climate change affects the environment in many different ways, including rising temperatures, sea level rise, drought, flooding, and more. These events affect things that we depend upon and value, like water, energy, transportation, wildlife, agriculture, ecosystems, and human health.
