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.

Climate change - Human Impact, Causes, Solutions | Britannica
Climate change - Human Impact, Causes, Solutions: Regardless of their locations on the planet, all humans experience climate variability and change within their lifetimes. The most familiar and predictable phenomena are the seasonal cycles, to which people adjust their clothing, outdoor activities, thermostats, and agricultural practices. However, no two summers or winters are exactly alike in ...
Climate change - Greenhouse Gases, Carbon Emissions, Global Warming ...
Climate change - Greenhouse Gases, Carbon Emissions, Global Warming: Greenhouse gases are gas molecules that have the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the phenomenon known as the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important ...
Climate change - Evidence, Causes, Impacts | Britannica
Climate change - Evidence, Causes, Impacts: All historical sciences share a problem: As they probe farther back in time, they become more reliant on fragmentary and indirect evidence. Earth system history is no exception. High-quality instrumental records spanning the past century exist for most parts of the world, but the records become sparse in the 19th century, and few records predate the ...
Climate change - Human Impact, Causes, Effects | Britannica
Climate change - Human Impact, Causes, Effects: The history of humanity—from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human species (Homo sapiens) beginning some 150,000 years ago—is integrally linked to climate variation and change. Homo sapiens has experienced nearly two full glacial-interglacial cycles, but its global ...
Climate change - Global Cooling, Ice Age, Human Impact | Britannica
Climate change - Global Cooling, Ice Age, Human Impact: The Earth system has undergone a general cooling trend for the past 50 million years, culminating in the development of permanent ice sheets in the Northern Hemisphere about 2.75 million years ago. These ice sheets expanded and contracted in a regular rhythm, with each glacial maximum separated from adjacent ones by 41,000 years (based on ...
Global warming - Climate Change, Melting Ice, Rising Sea Levels ...
Global warming - Climate Change, Melting Ice, Rising Sea Levels: Global warming and climate change have the potential to alter biological systems. More specifically, changes to near-surface air temperatures will likely influence ecosystem functioning and thus the biodiversity of plants, animals, and other forms of life. The current geographic ranges of plant and animal species have been ...
