Ocean Carbon Uptake Widely Underestimated The world’s oceans soak up much more carbon than most scientific models suggest, according to new research. Previous estimates of the movement of carbon (known as “flux”) between the atmosphere and oceans have not accounted for temperature differences at the water’s surface and a few […]

Calculated trends in geophysical PM2.5 values from 1998-2018. Warm colors indicate positive trends, cool colors indicate negative trends and the opacity of the colors indicates the statistical significance of the trends. Credit: Martin Lab Researchers’ hybrid dataset includes satellite images, modeling, and air samples. It is not unusual to come […]

The KunLun Differential Image Motion Monitors atop the 8-meter high tower at Dome A, Antarctica. Credit: Zhaohui Shang Dome A, the highest ice dome on the Antarctic Plateau, could offer the clearest view on Earth of the stars at night, according to new research by an international team from China, […]

This is an image of the ultraviolet “nightglow” in the Martian atmosphere over the south pole. Green and white false colors represent the intensity of ultraviolet light, with white being the brightest. The nightglow was measured at about 70 kilometers (approximately 40 miles) altitude by the Imaging UltraViolet Spectrograph instrument […]

A 23-million-year-old leaf preserved in a onetime New Zealand lake bed, key to past atmospheric conditions. One can see veins, glands along the teeth, and holes gnawed by insects, with resulting stunted growth and scar tissue.

The Light Detection and Ranging instrument, or LIDAR, is a remote sensing technique that uses light to study an object. Credit: ESA/IPEV/PNRA–S. Thoolen In a peninsula far, far away, a laser shoots into the sky to study the Antarctic atmosphere at Concordia research station. The Light Detection and Ranging instrument, […]

On September 18, 2017, ESA astronaut Paolo Nespoli shot this image from the International Space Station showing the Moon rising above the Earth’s horizon together with Mercury, Mars, the star Regulus, and Venus.

Coastal elevation in California. Coastal zones, which are defined to be those with elevations less than 10 m, are shown in red. Segments of the coast with elevations higher than 10 m are colored by a yellow gradient. Credit: USGS NED A majority of the world population lives on low […]

A blazing sunset lights up the evening sky. Credit: NOAA Four years of research confidently narrows range of 1.5°C-4.5°C down to 2.3°C-3.9°C. The most advanced and comprehensive analysis of climate sensitivity yet undertaken has revealed with more confidence than ever before how sensitive the Earth’s climate is to carbon dioxide. […]
