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. Changes observed in Earth's climate since the mid-20th century are driven by human activities, particularly fossil

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. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely

Climate change threatens people with increased flooding, extreme heat, increased food and water scarcity, more disease, and economic loss. Human migration and conflict can also be a result. [13] The World Health Organization (WHO) calls climate change the greatest threat to global health in the 21st century. [14]

Human activity is the principal cause. Earth-orbiting satellites and new technologies have helped scientists see the big picture, collecting many different types of information about our planet and its climate all over the world. These data, collected over many years, reveal the signs and patterns of a changing climate.

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

What Is Climate Change? Climate change refers to the long-term changes in global temperatures and other characteristics of the atmosphere. 1. Earth's Climate is Changing. We can see and measure climate changes around the world. Global temperature is warming, weather patterns are changing, polar ice is melting, and sea level is rising.

Scientists predict that it is highly likely that the rainfall patterns we all need for clean, fresh water will change, drying up in some places while causing floods in others. There is also significant evidence that, as a result of climate change, wildfires will worsen, destroying lives and property; that sea levels will rise, flooding many

What is climate change? Climate change refers to a large-scale, long-term shift in the planet's weather patterns and average temperatures. Climate change is the long-term shift in average weather patterns across the world. Since the mid-1800s, humans have contributed to the release of carbon dioxide and other greenhouse gases into the air.

Over hundreds of thousands of years, slow, recurring variations in Earth's orbit around the Sun, which alter the distribution of solar energy received by Earth, have been enough to trigger the ice age cycles of the past 800,000 years. Fingerprinting is a powerful way of studying the causes of climate change.

The terms "global warming" and "climate change" are sometimes used interchangeably, but "global warming" is only one aspect of climate change. "Global warming" refers to the long-term warming of the planet. Global temperature shows a well-documented rise since the early 20th century and most notably since the late 1970s. Worldwide since 1880, the average surface […]
