- What Is Climate Change? - Science@NASA
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 Changes observed in Earth’s climate since the mid-20th century are driven by human activities, particularly fossil fuel burning, which increases heat-trapping
- 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 The modern-day rise in global temperatures is driven by human activities, especially fossil fuel (coal, oil and natural gas) burning since
- Climate change | Definition, Causes, Effects, Facts | Britannica
Climate change, the periodic modification of Earth’s climate caused by atmospheric changes and the atmosphere’s interactions with geologic, chemical, biological, and geographic factors Loosely defined, climate is the average weather at a distinct place that incorporates temperature, precipitation, and other features

What is climate change? Climate change is the long-term shift in the Earth's average temperatures and weather conditions The world has been warming up quickly over the past 100 years or so
- Climate change: global temperature - NOAA Climate. gov
Earth's surface temperature has risen about 2 degrees Fahrenheit since the start of the NOAA record in 1850 It may seem like a small change, but it's a tremendous increase in stored heat

Climate change refers to long-term shifts in temperatures and weather patterns Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions But since the 1800s
- Impacts of Climate Change | US EPA
Climate change is happening Global average temperature has increased about 1 7°F from 1970 to 2023 1 Changes of one or two degrees in the average temperature of the planet can cause potentially dangerous shifts in climate and weather These real, observable changes are what we call climate change impacts because they are the visible ways that climate change is affecting the Earth For
