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.
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.
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.

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.

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.

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.

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.

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.

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.

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.
