Eight years ago: Warmest since modern recordskeeping began

Earth’s global average surface temperature in 2021 tied with 2018 as the sixth warmest on record, according to independent analyses done by NASA and the National Oceanic and Atmospheric Administration (NOAA). Continuing the planet’s long-term warming trend, global temperatures in 2021 were 1.5 degrees Fahrenheit (0.85 degrees Celsius) above the average for NASA’s baseline period,…

According to independent analyses by NASA and the National Oceanic and Atmospheric Administrations (NOAA), the Earth’s average surface temperature in 2021 is tied with 2018 and is the sixth-warmest record.

Continuing the planet’s warming trend, global temperatures were 1.5 degrees Fahrenheit (0. According to NASA scientists, 85 Celsius was higher than the average for NASA’s baseline period. This is according to GISS (NASA’s Goddard Institute for Space Studies) in New York. NASA uses the period from 1951-1980 as a baseline to see how global temperature changes over time.

The eight most recent years have been the warmest since the beginning of modern recordkeeping in 1880. These annual temperature data make up the global temperature record, which tells scientists that the planet is warming.

According to NASA’s temperature record, Earth in 2021 was about 1.9 degrees Fahrenheit (or about 1.1 degrees Celsius) warmer than the late 19th century average, the start of the industrial revolution.

“Science is clear: Climate change poses a serious threat to our world,” stated Bill Nelson, NASA Administrator. “Eighteen of the most 10 hot years on the planet were in the past decade. This is a clear indicator that bold action is needed to protect our nation’s future — and all humanity. NASA’s scientific research on how Earth is warming and changing will be used to guide communities around the globe, helping humanity face climate change and reduce its destructive effects. “

The global warming trend is caused by human activities, which have increased atmospheric carbon dioxide and other greenhouse gasses. Already, the planet is feeling the effects of global warming. Sea levels are dropping, wildfires are increasing, and animal migration patterns are changing. It is essential that humanity understands how and when the planet is changing. This is vital for adapting to a warmer world.

Weather stations and ships around the world record the temperature at Earth’s surface throughout the year. These ground-based measurements are validated by satellite data from NASA’s Aqua satellite. Scientists analyze these measurements using computer algorithms to deal with uncertainties in the data and quality cont
