2016 Warmest Year on Record according to NASA, NOAA

NASA - National Aeronautics and Space AdministrationWashington, 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.

NASA’s AIRS Instrument Tracks Series of Storms Battering California

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A series of atmospheric rivers that brought drought-relieving rains, heavy snowfall and flooding to California this week is highlighted in a new movie created with satellite data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite.

The images of atmospheric water vapor were collected by AIRS between January 7th and 11th. They show the amount of moisture present in the atmosphere and its movement across the Pacific Ocean to the United States, where much of it fell as rain or snow.

NASA’s Earth Science has a jammed packed 2017 planned

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA scientists, including many from NASA’s Jet Propulsion Laboratory, Pasadena, California, are crisscrossing the globe in 2017 — from a Hawaiian volcano to Colorado mountaintops and west Pacific islands — to investigate critical scientific questions about how our planet is changing and what impacts humans are having on it.

Field experiments are an important part of NASA’s Earth science research.

Three new NASA field research campaigns get underway around the world this year and nine continue fieldwork to give scientists a deeper understanding of how our home planet works. (NASA)

NASA looks to use Satellite Observations of Earth’s Magnetic Fields to Measure Ocean Heat

 

Written by Kate Ramsayer
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task.

A surprising feature of the tides could help, however. Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are developing a new way to use satellite observations of magnetic fields to measure heat stored in the ocean.

NASA’s International Space Station Rapid Scatterometer instrument ends operations

 

Written by Carol Rasmussen
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s International Space Station Rapid Scatterometer (ISS-RapidScat) Earth science instrument has ended operations following a successful two-year mission aboard the space station. The mission launched September 21st, 2014, and had recently passed its original decommissioning date.

ISS-RapidScat used the unique vantage point of the space station to provide near-real-time monitoring of ocean winds, which are critical in determining regional weather patterns. Its measurements of wind speed and direction over the ocean surface have been used by agencies worldwide for weather and marine forecasting and tropical cyclone monitoring.

NASA reports new study sheds light on slowdown of Global Warming

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new multi-institutional study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the Earth system, with Earth’s ocean absorbing the extra heat.

The phenomenon was referred to by some as the “global warming hiatus.” Global average surface temperature, measured by satellites and direct observations, is considered a key indicator of climate change.

NASA and FEMA conducts Asteroid Impacting Earth Simulation Exercise

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – What would we do if we discovered a large asteroid on course to impact Earth? While highly unlikely, that was the high-consequence scenario discussed by attendees at an October 25th NASA-FEMA tabletop exercise in El Segundo, California.

The third in a series of exercises hosted jointly by NASA and FEMA — the Federal Emergency Management Agency — the simulation was designed to strengthen the collaboration between the two agencies, which have Administration direction to lead the U.S. response.

NASA tracks Rainfall of Hurricane Earl over Mexico

 

Written by Hal Pierce and Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Hurricane Earl began as a tropical wave that was tracked by the National Hurricane Center (NHC) from the African coast to the Caribbean Sea. The tropical wave drenched the Dominican Republic, where it was blamed for the deaths of six people.

Southwest of Jamaica on August 2nd, 2016, the tropical wave developed a closed circulation, and Earl was upgraded to a tropical storm.

On August 3rd, Earl became a hurricane when it was located about 150 miles east of Belize. On August 4th Earl made landfall just southwest of Belize City, Belize, at about 2:00am EDT (6:00am UTC).

The analysis of rainfall from Aug. 2 through Aug. 8, 2016, showed the period from when Earl became a tropical storm until Earl's remnants interacted with an area of disturbed weather along the Pacific coast. Some areas in extreme southern Mexico received up to 43.3 inches (1,100 mm) of rain. Earl's locations and intensities, as defined by the National Hurricane Center (NHC), are shown overlaid in white.

NASA Researchers study how Microgravity affects Tiny Organisms in Space

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – On May 11th, a sealed capsule containing fungi and bacteria fell from the sky and splashed down in the Pacific Ocean. Microbiologist Kasthuri Venkateswaran could hardly wait to see what was inside it.

At NASA’s Jet Propulsion Laboratory in Pasadena, California, Venkateswaran, who goes by Venkat, studies microbial life — the wild world of organisms too small for us to see with our eyes. Among his many research endeavors, Venkat has leading roles on two microbial experiments that recently returned from the International Space Station.
