NASA catches the re-birth of zombie tropical cyclone Francisco

The low-pressure area that had once been Tropical Cyclone Francisco has been lingering in the Southern Indian Ocean since Feb. 6 when it weakened below tropical cyclone status. Since then, Francisco’s remnants moved into an area of warm waters and…

NASA finds ex-Tropical Cyclone Uesi’s rains affecting New Zealand

Although it is now an “ex-tropical cyclone,” Uesi continues to generate some moderate rainfall, especially in its southern quadrant as it moves toward New Zealand. The Global Precipitation Measurement mission or GPM satellite provided a look at the rainfall rates…

NASA finds wind shear affecting tropical cyclone Uesi

NASA satellite imagery revealed that vertical wind shear appears to be affecting Tropical Cyclone Uesi in the Southern Pacific Ocean. On Feb. 13 at 0315 UTC (Feb. 12 at 10:15 p.m. EST), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument…

NASA finds heavy rain southwest of tropical cyclone Uesi’s center

The Global Precipitation Measurement mission or GPM satellite provided a look at the rainfall occurring within Tropical Cyclone Uesi and found heaviest rainfall in the southern quadrant of the storm. Uesi is in the South Pacific Ocean and has been…

Small altitude changes could cut the climate impact of aircraft

Contrails — the white, fluffy streaks in the sky that form behind planes — can harm the environment. Now, scientists report in ACS’ Environmental Science & Technology that small flight path adjustments could reduce the climate impact of these emissions.…

Small altitude changes could cut climate impact of aircraft by up to 59%

Aircraft contrails – the white streaks aircraft leave in the sky – could be as bad for the climate as their carbon dioxide (CO2) emissions. Now, new Imperial College London-led research has found that flight altitude changes of just 2000…

NASA finds a stronger Tropical Cyclone Uesi near New Caledonia

NASA’s Terra satellite passed over the South Pacific Ocean and found a stronger Tropical Cyclone Uesi after obtaining infrared imagery of the storm. Uesi continues moving away from Vanuatu and today is affecting New Caledonia. Infrared data provides temperature information,…

NASA analyzes ex-Tropical Cyclone Damien’s rainfall in Western Australia

Tropical Cyclone Damien made landfall on Feb. 9 along the northern Pilbara coast of Western Australia. On Feb. 10, the GPM or Global Precipitation Measurement mission core satellite analyzed the rainfall generated by the remnants that triggered warnings. As Damien…

NASA examines Tropical Storm Uesi’s heavy rainfall

NASA analyzed Tropical Storm Uesi’s rainfall and found moderate to heavy rainfall around the storm’s center and in a large band of thunderstorms south of the center. That heavy rainfall has triggered warnings for Vanuatu in the Southern Pacific Ocean.…

There’s a twist in the story of volcanism & mass extinctions, say CCNY researchers

An emerging scientific consensus is that gases–in particular carbon gases–released by volcanic eruptions millions of years ago contributed to some of Earth’s greatest mass extinctions. But new research at The City College of New York suggests that that’s not the…

Scientists show solar system processes control the carbon cycle throughout Earth’s history

The world is waking up to the fact that human-driven carbon emissions are responsible for warming our climate, driving unprecedented changes to ecosystems, and placing us on course for the sixth mass extinction event in Earth’s history. However, new research…

Simulations identify missing link to determine carbon in deep Earth reservoirs

Understanding the Earth’s carbon cycle has important implications for understanding climate change and the health of biospheres. But scientists don’t yet understand how much carbon lies deep in the Earth’s water reservoirs — for example, in water that is under…

NASA analyzes tropical cyclone Damien’s water vapor concentration

When NASA’s Aqua satellite passed over the Southern Indian Ocean on Feb. 7, it gathered water vapor data that provided information about the intensity of Tropical Cyclone Damien. On Feb. 7 at 12:25 a.m. EST (1725 UTC), NASA’s Aqua satellite…

NASA sees tropical storm Damien form off Australia’s Pilbara coast

The low-pressure area that formed off Australia’s Kimberley coast and lingered there for a couple of days has moved west and developed into Tropical Cyclone Damien off the Pilbara coastline. NASA’s Terra satellite passed over the Southern Indian Ocean and…

Trees in the Amazon are time capsules of human history, from culture to colonialism

As society has progressed, the annals of human history have been recorded through text, art, and oral tradition. However, for hundreds of years tropical forests have also kept detailed records of the human activities that unfolded around them. In a…
