World of Change: Global Temperatures - NASA Earth Observatory
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.
Global Warming - NASA Earth Observatory
Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels. How Does Today’s Warming Compare to Past Climate Change?
If Earth has warmed and cooled throughout history, what makes ...
May 4, 2010 · If Earth has warmed and cooled throughout history, what makes scientists think that humans are causing global warming now? The first piece of evidence that the warming over the past few decades isn’t part of a natural cycle is how fast the change is happening.
2021 Continued Earth’s Warming Trend - NASA Earth Observatory
Jan 13, 2022 · The planet is already seeing the effects of global warming: Arctic sea ice is declining, sea levels are rising, and wildfires are becoming more severe. Understanding how the planet is changing—and how rapidly those changes are occurring—is crucial for preparing humanity to adapt to a warmer future.

What is Global Warming? Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
Global Warming - NASA Earth Observatory
Global warming is happening now, and scientists are confident that greenhouse gases are responsible. To understand what this means for humanity, it is necessary to understand what global warming is, how scientists know it's happening, and how they predict future climate.
Earth’s Temperature Tracker - NASA Earth Observatory
NASA scientist James Hansen has tracked Earth's temperature for decades, and he is confident the global warming trend of 0.9 degrees Celsius observed since 1880 is mainly the result of human-produced greenhouse gases.

Climate Q&A - Are the ozone hole and global warming related?
Global warming is the rise in average global surface temperature caused primarily by the build-up of human-produced greenhouses gases, mostly carbon dioxide and methane, which trap heat in the lower levels of the atmosphere. There are some connections between the two phenomena.
Climate Q&A - Why is global warming a problem? - NASA Earth …
Jul 6, 2010 · Why is global warming a problem? The cost and benefits of global warming will vary greatly from area to area. For moderate climate change, the balance can be difficult to assess. But the larger the change in climate, the more negative the consequences will become.
