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 […]

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 […]

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 […]

MIT Scientists Observe First Signs of Healing in the Antarctic Ozone Layer

New research details the “first fingerprints of healing” of the Antarctic ozone layer. Scientists found that the September ozone hole has shrunk by more than 4 million square kilometers — about half the area of the contiguous United States — since 2000, when ozone depletion was at its peak. The team also showed for the […]

New Research Traces the Impact of Volcanic Activity on Climate Change

A newly published study shows that for the majority of Earth’s history, continental arc volcanism has been the main driver of long-term climate variability. A geology-based analysis of Earth’s climate history over the past 700 million years provides evidence that climate change has occurred traditionally through slow shifts in the release of carbon dioxide — […]

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 […]

Tiny Plankton May Have a Big Effect on the Ocean’s Carbon Storage

New research from MIT and Bristol University reveal that microscopic, mixotrophic organisms may have a large impact on the ocean’s food web and the global carbon cycle. How do you find your food? Most animal species, whether they rummage through a refrigerator or stalk prey in the wild, obtain nutrients by consuming living organisms. Plants, […]

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 […]

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 […]

A New Way to Track Ocean Currents from Space

Scientists have developed a new way to use satellite measurements to track changes in Atlantic Ocean currents. The finding opens a path to better monitoring and understanding of how ocean circulation is changing and what the changes may mean for future climate. In the Atlantic, currents at the ocean surface, such as the Gulf Stream, […]

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 […]

NASA Studying Never Before Seen El Niño Event

NASA scientists continue to monitor and study this year’s El Niño, which appears likely to equal the event of 1997-98 – the strongest El Niño on record. Every two to seven years, an unusually warm pool of water — sometimes two to three degrees Celsius higher than normal – develops across the eastern tropical Pacific […]

Researchers Conduct Climate Change Test for Forests

Biologists from Harvard University are examining whether the earlier arrival of warm weather will clash with genetic programming of plants. Harvard scientists are taking a hard look at northeastern forests for evidence of a potential springtime scramble, one that could be triggered if age-old growth cues are disrupted by climate change. Researchers in the Department […]
