Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [35] [36] [37] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [34]
The health effects of climate change are expected to rise in line with projected ongoing global warming for different climate change scenarios. [127] [128] A review [129] found if warming reaches or exceeds 2 °C this century, roughly 1 billion premature deaths would be caused by anthropogenic global warming. [130]
Greenhouse effect. Energy flows down from the sun and up from the Earth and its atmosphere. When greenhouse gases absorb radiation emitted by Earth's surface, they prevent that radiation from escaping into space, causing surface temperatures to rise by about 33 °C (59 °F). The greenhouse effect occurs when greenhouse gases in a planet's ...
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 ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 17 September 2024. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Climate change feedbacks are natural processes which impact how much global temperatures will increase for a given amount of greenhouse gas emissions. Positive feedbacks amplify global warming while negative feedbacks diminish it. [2]: 2233 Feedbacks influence both the amount of greenhouse gases in the atmosphere and the amount of temperature ...
Global action is also needed to mitigate the negative impacts of climate change on the environment and human health. However, there are many ways we can make changes individually for our health ...
