2019年9月2日 · With these images compared over time, you can see the toll the warming of the Earth is taking on the planet. Below are some examples from NASA’s Images of Change project, which shows areas that...

2023年3月29日 · In addition to comparison views of before-and-after images, you can now view selected scenes as time-lapse sequences generated via the Google Earth engine. The following collection features examples of global change as observed by NASA satellites, including urbanization, natural hazards, weather events, and the effects of global warming.

According to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880. The majority of the warming has occurred since 1975, at a rate of roughly 0.15 to 0.20°C per decade.

2021年1月4日 · The Earth’s climate and atmosphere have changed drastically over the last 4.5 billion years. Today’s global average temperature is around 59°F, but scientists estimate it has been as low as 10°F 1 (during “snowball Earth” events) and as high as 95°F or above 2 (so hot the Arctic North resembled today’s tropics). The atmosphere has ...

2023年9月21日 · Explore a stunning gallery of before-and-after images of Earth from land and space that reveal our home planet in a state of flux. Climate Time Machine Travel through Earth's recent climate history and see how increasing carbon dioxide, global temperature and sea ice have changed over time.

2024年8月15日 · Visualize satellite data, see changes over time on land, glaciers, and in the ocean, and discover evidence for Earth’s past climates. Then, test your knowledge with one of our quizzes. Before-and-after images of Earth.

2003年8月23日 · Our Images of Change gallery features images of different locations on planet Earth, showing change over time periods ranging from centuries to days. Some of these effects are related to climate change, some are not. Some document the effects of urbanization, or the ravage of natural hazards such as fires and floods.

There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause. Why Is Climate Change Happening? Human activities are driving the global warming trend observed since the mid-20th century. What Are the Effects of Climate Change?

2025年1月10日 · However, the warming spike in 2023/2024 appears to have deviated significantly from the previous trend. If we were to assume that global warming was continuing at the same rate as during the 50-year period 1970-2019, then the 2023/2024 excursion would be by far the largest deviation from that trend, with only a roughly 1-in-100 chance of occurring solely due to natural variability.

2020年10月29日 · Earth has warmed in the past due to changes in the Sun, volcanic eruptions, and naturally occurring increases in greenhouse gases. Our ability to understand and explain past changes is one reason we are confident that recent changes are due to humans.
