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)

NASA Study reveals nearly one-fifth of Global Warming over the years has been missed

July 23, 2016 |

Written by Alan Buis

Pasadena, CA – A new NASA-led study finds that almost one-fifth of the global warming that has occurred in the past 150 years has been missed by historical records due to quirks in how global temperatures were recorded. The study explains why projections of future climate based solely on historical records estimate lower rates of warming than predictions from climate models.

The study applied the quirks in the historical records to climate model output and then performed the same calculations on both the models and the observations to make the first true apples-to-apples comparison of warming rates.

NASA, NOAA data shows Earth’s 2015 surface temperatures were the highest in History

Washington, D.C. – Earth’s 2015 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 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much.

2015 was the warmest year since modern record-keeping began in 1880, according to a new analysis by NASA’s Goddard Institute for Space Studies. The record-breaking year continues a long-term warming trend — 15 of the 16 warmest years on record have now occurred since 2001. (Scientific Visualization Studio/Goddard Space Flight Center)

NASA Earth-Imaging satellites used for Global Agricultural Monitoring

Washington, D.C. – When global food prices spiked dramatically in late 2007 and into 2008, the costs of many basic dietary staples doubled or even tripled around the world, sparking protests and riots. Panicked governments stopped exporting food, aggravating the crisis.

Almost as troubling: the crisis had taken the world by surprise.

To keep it from happening again, international leaders created an agricultural monitoring group, bringing together representatives from governments and aid groups.

The Group on Earth Observation’s Global Agricultural Monitoring (GEOGLAM) was created to make better predictions about weather and future crops. (NASA)

NASA’s Soil Moisture Active Passive (SMAP) instrument to be launched into space in January

NASA’s Jet Propulsion Laboratory

Pasadena, CA – It’s active. It’s passive. And it’s got a big, spinning lasso.

Scheduled for launch on January 29th, 2015, NASA’s Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth’s soils with an unprecedented accuracy and resolution. The instrument’s three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.

Remote sensing instruments are called “active” when they emit their own signals and “passive” when they record signals that already exist.

NASA to investigate Climate change with Airborne Campaigns

Pasadena, CA – Five new NASA airborne field campaigns, including one managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, will take to the skies starting in 2015 to investigate how long-range air pollution, warming ocean waters and fires in Africa affect our climate.

These studies into several incompletely understood Earth system processes were competitively selected as part of NASA’s Earth Venture-class projects. Each project is funded at a total cost of no more than $30 million over five years. This funding includes initial development, field campaigns and analysis of data.

Pasadena, CA – NASA successfully launched its first spacecraft dedicated to studying atmospheric carbon dioxide at 2:56am PDT (6:56am CDT) Wednesday.

The Orbiting Carbon Observatory-2 (OCO-2) raced skyward from Vandenberg Air Force Base, California, on a United Launch Alliance Delta II rocket. Approximately 56 minutes after the launch, the observatory separated from the rocket’s second stage into an initial 429-mile (690-kilometer) orbit.

NASA’s Carbon Observatory-2 satellite set for July 1st launch

Washington, D.C. – In the lexicon of climate change, one word appears more often than any other: “carbon.” Carbon credits, carbon emissions, carbon sequestration…. These terms are on everyone’s lips.

The reason is carbon dioxide (CO2).

According to the Intergovernmental Panel on Climate Change, CO2 is the most important driver of global warming. At approximately 400 parts per million, atmospheric carbon dioxide is now at its highest level in at least the past 800,000 years.

Pasadena, CA – A NASA-developed airborne imager called a synthetic aperture radar took a detailed look at volcanoes in Central and South America during an Earth science study in late April and early May 2014.

The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, was flown on NASA’s C-20A. The 29-day deployment ended May 6th when the aircraft returned to its base in Palmdale, California, after 19 flights totaling 97 hours in the air.
