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.
3 days ago · What is climate change? 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.

Weatherdescribes the conditions outside right now in a specific place. For example, if you see that it’s raining outside right now, that’s a way to describe today’s weather. Rain, snow, wind, hurricanes, tornadoes — these are all weather events. Climate, on the other hand, is more than just one or two rainy days. Climate describes the weather condi...
Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. For example, 20,000 years ago, much of the United States was covered in glaciers. In the United States today, we have a warmer climate and fewer glaciers. Global climate change refers to the average long-term chan...
Some parts of Earth are warming faster than others. But on average, global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the past 100 years. In fact, the past five years have been the warmest five years in centuries. Many people, including scientists, are concerned about this warming. As Earth’s climate continues ...
There are lots of factors that contribute to Earth’s climate. However, scientists agree that Earth has been getting warmer in the past 50 to 100 years due to human activities. Certain gases in Earth’s atmosphere block heat from escaping. This is called the greenhouse effect. These gases keep Earth warm like the glass in a greenhouse keeps plants wa...
Yes. When human activities create greenhouse gases, Earth warms. This matters because oceans, land, air, plants, animals and energy from the Sun all have an effect on one another. The combined effects of all these things give us our global climate. In other words, Earth’s climate functions like one big, connected system. Thinking about things as sy...
Climate change (or global warming), is the process of our planet heating up. Scientists estimate that since the Industrial Revolution, human activity has caused the Earth to warm by approximately 1°C. While that might not sound like much, it means big things for people and wildlife around the globe.
Weather changes day to day—sometimes it rains, other days it’s hot. Climate is the pattern of the weather conditions over a long period of time for a large area. And climate can be affected by...
May 14, 2014 · 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.
Apr 9, 2020 · It is changes in usual weather patterns in a region that last a long time. These changes are seen or felt in ice and snow cover, sea level, hot and cold temperatures, rainfall, and wind patterns. Different parts of the world will see different changes.
