What is the scientific definition of 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. … Scientists use observations from the ground, air and space, along with theoretical models, to monitor and study past, present and future climate change.

What is climate change simple definition?

Climate change is the long-term alteration of temperature and typical weather patterns in a place. … The cause of current climate change is largely human activity, like burning fossil fuels, like natural gas, oil, and coal. Burning these materials releases what are called greenhouse gases into Earth’s atmosphere.

What is the scientific basis of climate change?

Climate change has been observed in patterns of temperature, humidity and rainfall, as well as in the frequency or intensity of extreme weather events. These are complex effects that are influenced by many natural and human factors, making it difficult to precisely predict how they will develop in future.

What is climate change definition Wikipedia?

Climate change means the climate of Earth changing. … Over very large time periods, climate change is caused by variations in the Earth’s orbit around the Sun. The Earth has been much warmer and much cooler than it is today.

“Climate change” means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

What is climate change kids?

Climate change refers to the long-term changes in global temperatures and other characteristics of the atmosphere. Climate has changed throughout Earth’s long history, but this time it’s different. Human activity is causing worldwide temperatures to rise higher and faster than any time we know of in the past.

What is climate change causes and effects?

Human activities, such as burning fossil fuels and destroying rainforests, have an increasing influence on the climate and the Earth’s temperature. This adds huge quantities of greenhouse gases to those naturally present in the atmosphere, increasing the greenhouse effect and global warming.

What are the 5 causes of climate change?
