New Technique Predicts Frequency of Heavy Precipitation with Global Warming

Researchers from MIT reveal that extreme precipitation events should become more frequent as the Earth’s climate warms over this century. On December 11, 2014, a freight train of a storm steamed through much of California, deluging the San Francisco Bay Area with three inches of rain in just one hour. The storm was fueled by […]

NASA’s New Global View of CO2, Critical Step for Carbon-Cycle Science

December 13, 2016


Eye-Popping View of CO2, Critical Step for Carbon-Cycle Science

NASA’s new global view of carbon dioxide builds on the agency’s previous satellite measurements of carbon dioxide and combines them with a sophisticated Earth system model to provide one of the most realistic views yet of how this critical greenhouse gas moves through the atmosphere. Scientists have tracked the rising concentration of heat-trapping carbon dioxide […]

NASA Observes Early Noctilucent Ice Clouds Over Antarctica

Data from NASA’s Aeronomy of Ice in the Mesosphere spacecraft shows the sky over Antarctica is glowing electric blue due to the start of noctilucent, or night-shining, cloud season in the Southern Hemisphere – and an early one at that. Noctilucent clouds are Earth’s highest clouds, sandwiched between Earth and space 50 miles above the […]

How Arctic Sea Ice Is Losing Its Bulwark Against Warming Summers

New research shows that the Arctic sea ice has been hit with a double whammy over the past decades: as its extent shrunk, the oldest and thickest ice has either thinned or melted away, leaving the sea ice cap more vulnerable to the warming ocean and atmosphere. “What we’ve seen over the years is that […]

US Counties Risk Exposure to Pollution from Wildfires

Newly published research identifies the western U.S. counties with the highest risk of exposure to pollution from wildfires. Wildfires threaten more than land and homes. The smoke they produce contains fine particles (PM2.5) that can poison the air for hundreds of miles. Air pollution from the 2016 Fort McMurray fire in northern Alberta, Canada, sent […]

Van Allen Probes Catch Rare Glimpse of Supercharged Radiation Belt

New research details how a shockwave created by the driving force of a coronal mass ejection from the sun – struck the outermost radiation belt, triggering the greatest geomagnetic storm of the preceding decade. Our planet is nestled in the center of two immense, concentric doughnuts of powerful radiation: the Van Allen radiation belts, which […]

Is Life on Earth Premature from a Cosmic Perspective?

Is Life on Our Planet Premature from a Cosmic Perspective?

New research from the Harvard-Smithsonian Center for Astrophysics examines the possibility that present-day life is actually premature from a cosmic perspective. The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other planets could be billions of years older […]

New NASA Study Shows Historical Records Miss a Fifth of Global Warming

New research led by NASA scientists reveals 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 […]

Astronomers Track the Source of Slow Solar Wind

May 11, 2016


Implications of L1 Observations for Slow Solar Wind

Using newly processed observations, astronomers spot tell-tale signs that the slow solar wind passing Earth originated from a magnetic phenomenon known as magnetic reconnection. From our vantage point on the ground, the sun seems like a still ball of light, but in reality, it teems with activity. Eruptions called solar flares and coronal mass ejections […]

Climate Change Threatens Dark Taiga

New research from the Max Planck Institute of Biochemistry reveals that Boreal coniferous forests could see increased occurrences of fire as a result of global warming, with deciduous trees becoming more dominant in the future. Climate change is transforming the Earth, particularly in high-latitude regions. The boreal coniferous forests of the northern hemisphere will witness […]

New Study Shows Long-Term Global Warming Needs External Drivers

New research from NASA and Duke University provides new evidence that natural cycles alone aren’t sufficient to explain the global atmospheric warming observed over the last century. A study by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, and Duke University in Durham, North Carolina, shows, in detail, the reason why global temperatures remain […]

NASA Details Record-Shattering Global Warm Temperatures from 2015

&nbs According to independent analyses by NASA and the National Oceanic and Atmospheric Administration, Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880. 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 […]

A Still-Growing El Niño Set to Bear Down on USA

The latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission shows that the current strong El Niño brewing in the Pacific Ocean shows no signs of waning. El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts […]

Researchers Find a Soft Spot in a Tectonic Slab

Using land-based seismic stations, researchers from Yale University found that part of the Nazca Plate weakened and deformed as it bent and slid under the adjoining South American Plate. The Earth’s tectonic plates may be more flexible than previously thought as they slide underneath each other and dive deep below the surface, according to new […]

Temperature of Ancient Seas Shape Global Climate

In a newly published study, scientists from Yale University detail the differences in ocean temperatures over the last 5 million years by creating a historical record for sea temperature gradients and comparing it with state-of-the-art climate model simulations. The study is published in the journal Nature Geoscience. Sea temperature gradients (contrasts) in the tropics and […]

Annual Antarctic Ozone Hole is Larger

Scientists from NASA and the National Oceanic and Atmospheric Administration reveal that the 2015 Antarctic ozone hole area was larger and formed later than in recent years. On October 2, 2015, the ozone hole expanded to its peak of 28.2 million square kilometers (10.9 million square miles), an area larger than the continent of North […]

Study Shows Greenland Ice Sheet Movement Decreasing Despite Warming

A newly published study from the University of Edinburgh shows that the movement of the southwest portion of the Greenland Ice Sheet that terminates on land has been slowing down despite decades of increasing temperatures and surface melting. The study is published in the journal Nature. Researchers derived their results by tracking ice sheet movement […]
