In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is primarily caused by humans burning fossil fuels since the Industrial Revolution. ...
2 days ago · 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.
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, […]
What Is Climate Change? 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.

Feb 8, 2024 · Climate change is the long-term shift in the Earth's average temperatures and weather conditions. Over the last decade, the world was on average around 1.2C warmer than during the late 19th Century.
Climate change is the significant variation of average weather conditions becoming, for example, warmer, wetter, or drier—over several decades or longer. It is the longer-term trend that differentiates climate change from natural weather variability. Human activity leads to change in the atmospheric composition either directly (via emissions of gases or particles) or indirectly (via atmospheric chemistry). Anthropogenic emissions have driven the changes in WMGHG concentrations during the ...
What is causing climate change? Human activities are driving the global warming trend observed since the mid-20th century. Scientists attribute the global warming trend observed since the mid-20 th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space.
Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent ...
Current climate change is primarily caused by human emissions of greenhouse gases. This warming can drive large changes in sea level, sea ice and glacier balances, rainfall patterns, and extreme temperatures. This has potentially devastating impacts on human health, farming systems, the stability of societies, and other species.
