NASA Analysis shows 2020 Tied for Warmest Year on Record

January 19, 2021 |

Washington, D.C. – Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.

Continuing the planet’s long-term warming trend, the year’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. 2020 edged out 2016 by a very small amount, within the margin of error of the analysis, making the years effectively tied for the warmest year on record.

This plot shows yearly temperature anomalies from 1880 to 2019, with respect to the 1951-1980 mean, as recorded by NASA, NOAA, the Berkeley Earth research group, and the Met Office Hadley Centre (UK). Though there are minor variations from year to year, all five temperature records show peaks and valleys in sync with each other. All show rapid warming in the past few decades, and all show the past decade has been the warmest. (NASA GISS/Gavin Schmidt)

NASA’s Measure of Earth’s Temperature accuracy confirmed by new study

May 28, 2019 |

Greenbelt, MD – A new assessment of NASA’s record of global temperatures revealed that the agency’s estimate of Earth’s long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values are likely accurate to within 0.09 degrees Fahrenheit (0.05 degrees Celsius) in recent decades, and 0.27 degrees Fahrenheit (0.15 degrees C) at the beginning of the nearly 140-year record.

Earth’s long-term warming trend can be seen in this visualization of NASA’s global temperature record, which shows how the planet’s temperatures are changing over time, compared to a baseline average from 1951 to 1980. The record is shown as a running five-year average. (NASA’s Scientific Visualization Studio/Kathryn Mersmann)

NASA, NOAA say 2018 Fourth Warmest Year since 1880

February 7, 2019 |

NASA Headquarters 

Washington, D.C. – Earth’s global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).

Global temperatures in 2018 were 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. Globally, 2018’s temperatures rank behind those of 2016, 2017 and 2015. The past five years are, collectively, the warmest years in the modern record.

This line plot shows yearly temperature anomalies from 1880 to 2018, with respect to the 1951-1980 mean, as recorded by NASA, NOAA, the Japan Meteorological Agency, the Berkeley Earth research group, and the Met Office Hadley Centre (UK). (NASA’s Earth Observatory)

American Heart Association says Climate Change may increase Congenital Heart Defects

January 31, 2019 |

Journal of the American Heart Association Report

Dallas, TX – Rising temperatures stemming from global climate change may increase the number of infants born with congenital heart defects (CHD) in the United States over the next two decades and may result in as many as 7,000 additional cases over an 11 year-period in eight representative states (Arkansas, Texas, California, Iowa, North Caroline, Georgia, New York and Utah), according to new research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

The greatest percentage increases in the number of congenital heart defects are predicted in the Midwest, followed by the Northeast and the South. (American Heart Association)

NASA’s studying of Earth will help to discover Life on another Planet

Washington, D.C. – As a young scientist, Tony del Genio of NASA’s Goddard Institute for Space Studies in New York City met Clyde Tombaugh, the discoverer of Pluto.

“I thought, ‘Wow, this is a one-time opportunity,'” del Genio said. “I’ll never meet anyone else who found a planet.”

That prediction was spectacularly wrong. In 1992, two scientists discovered the first planet around another star, or exoplanet, and since then more people have found planets than throughout all of Earth’s preceding history.

NASA finds Red Dwarf Star with several Earth Size Planets in Orbit

February 24, 2017 |

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

Pasadena, CA – A bumper crop of Earth-size planets huddled around an ultra-cool, red dwarf star could be little more than chunks of rock blasted by radiation, or cloud-covered worlds as broiling hot as Venus.

Or they could harbor exotic lifeforms, thriving under skies of ruddy twilight.

Scientists are pondering the possibilities after this week’s announcement: the discovery of seven worlds orbiting a small, cool star some 40 light-years away, all of them in the ballpark of our home planet in terms of their heft (mass) and size (diameter). Three of the planets reside in the “habitable zone” around their star, TRAPPIST-1, where calculations suggest that conditions might be right for liquid water to exist on their surfaces—though follow-up observations are needed to be sure.

This illustration shows the seven planets orbiting TRAPPIST-1, and ultra-cool dwarf star, as they might look as viewed from Earth using a fictional, incredibly powerful telescope. (NASA-JPL/Caltech)

2016 Warmest Year on Record according to NASA, NOAA

Washington, D.C. – Earth’s 2016 surface temperatures were the warmest since modern record keeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).

Globally-averaged temperatures in 2016 were 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean. This makes 2016 the third year in a row to set a new record for global average surface temperatures.

The 2016 temperatures continue a long-term warming trend, according to analyses by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

2016 was the hottest year on record, continuing a decades-long warming trend. Scientists at NASA’s Goddard Institute for Space Studies (GISS) analyzed measurements from 6,300 locations and found that Earth’s average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late-19th century, largely a result of human emissions into the atmosphere.

New York, NY – October 2016 was the second warmest October in 136 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

October 2016’s temperature was 0.18 degrees Celsius cooler than the warmest October in 2015. Last month was 0.89 degrees Celsius warmer than the mean October temperature from 1951-1980.

NASA Analysis Finds July 2016 is Warmest on Record

August 18, 2016 |

NASA’s Goddard Space Flight Center

Greenbelt, MD – July 2016 was the warmest July in 136 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

Because the seasonal temperature cycle peaks in July, it means July 2016 also was warmer than any other month on record. July 2016’s temperature was a statistically small 0.1 degrees Celsius warmer than previous warm Julys in 2015, 2011 and 2009.

NASA Satellite Data shows High Altitude Clouds shifting to Earth’s Poles

May 10, 2016 |

Written by Ellen Gray
NASA’s Earth Science News Team

Washington, D.C. – A new NASA analysis of 30-years of satellite data suggests that a previously observed trend of high altitude clouds in the mid-latitudes shifting toward the poles is caused primarily by the expansion of the tropics.

Clouds are among the most important mediators of heat reaching Earth’s surface. Where clouds are absent, darker surfaces like the ocean or vegetated land absorb heat, but where clouds occur their white tops reflect incoming sunlight away, which can cause a cooling effect on Earth’s surface.

The Hadley cells describe how air moves through the tropics on either side of the equator. They are two of six major air circulation cells on Earth. (NASA)
