Early this morning, NASA launched the Orbiting Carbon Observatory (OCO-2), a new science satellite that will measure Earth's output and uptake of carbon dioxide—the leading greenhouse gas responsible for climate change.
Both NASA and NOAA have ranked May 2014 as the planet’s hottest May since records began in 1880. UPDATE (Jul 22, 2014): NOAA has ranked June 2014 as Earth's hottest June on record, making it the second such record-breaking month in a row.
A new EPA report presents a set of 30 indicators that track the causes and effects of climate change. Written for general audiences, the report aims to help readers understand long-term climate-related trends observed across the atmosphere, oceans, snow and ice, ecosystems, and public health.
As part of President Obama's Climate Action Plan, the Administration recently announced an interagency National Drought Resilience Partnership to help communities better prepare for future droughts and reduce the impact of drought events on livelihoods and the economy.
On May 9, 2013, the daily mean concentration of carbon dioxide in the atmosphere surpassed 400 parts per million (ppm) for the first time since measurements began in 1958 at Mauna Loa Observatory in Hawaii.
A recently published report summarizes past and present-day changes in the Earth’s cryosphere and describes the ongoing and potential effects of those changes.
NASA's Goddard Institute for Space Studies (GISS) in New York, which monitors global surface temperatures on an ongoing basis, released an updated analysis today that compares temperatures around the globe in 2012 to the average global temperature from the mid-20th century.
The latest State of the Climate National Overview report from the National Oceanic and Atmospheric Administration (NOAA) and NOAA's National Climatic Data Center reveals that 2012 was the United States’ warmest year on record by a wide margin.
In front of the United States Geological Survey (USGS) national headquarters building in Reston, Va., two genetically identical lilac bushes are rooted in the earth. To casual observers, they are fragrant adornments to the landscaped property. But to ecologist Jake Weltzin and geographer John Jones—USGS scientists who study plant and animal life-cycle events—they are “Li” and “Lac,” two small but important pieces of a developing climate change indicator system.
The average global temperature for July 2012 was more than 1Fahrenheit above the 20th-century average, making it the fourth warmest July since record keeping began in 1880.
