What is climate change according to who?

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.

What is climate change best definition?

Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. … There, these gases trap heat from the sun’s rays inside the atmosphere causing Earth’s average temperature to rise.

How do you explain climate change?

Climate change is a change in the pattern of weather, and related changes in oceans, land surfaces and ice sheets, occurring over time scales of decades or longer. Weather is the state of the atmosphere—its temperature, humidity, wind, rainfall and so on—over hours to weeks.

Who first defined climate change?

Eighty years ago, Guy Callendar built the first climate change model to predict the effects of greenhouse gases. Now his successors are plotting ways to reengineer the air.

What is climate change according to NASA?

Climate change is a change in the usual weather found in a place. This could be a change in how much rain a place usually gets in a year. Or it could be a change in a place’s usual temperature for a month or season. Climate change is also a change in Earth’s climate. This could be a change in Earth’s usual temperature.

How do you explain climate change to a child?

Climate change describes a change in the typical weather for a region — such as high and low temperatures and amount of rainfall — over a long period of time. Scientists have observed that, overall, Earth is warming. In fact, many of the warmest years on record have happened in the past 20 years.

What is climate short answer?

Climate is the average weather in a given area over a longer period of time. A description of a climate includes information on, e.g. the average temperature in different seasons, rainfall, and sunshine. Also a description of the (chance of) extremes is often included.

What is climate change simple?

Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. … These include warming temperatures and changes in precipitation, as well as the effects of Earth’s warming, such as: Rising sea levels. Shrinking mountain glaciers.

What caused climate change?

The evidence is clear: the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.

What are the 5 causes of climate change?

The National found out the five main culprits for this increase in greenhouse gases.

  • Fossil fuels. Expand Autoplay. …
  • Deforestation. …
  • Increasing livestock farming. …
  • Fertilisers containing nitrogen. …
  • Fluorinated gases.

When did climate change become known?

The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified.
