Larisza Krista’s movie of the 2012 total solar eclipse in Queensland, Australia didn’t require a zoom lens, a solar filter, a tripod, or a video camera. Instead, it took computer programming and hundreds of still photos. Krista developed a tool to process solar eclipse images from many sources and stitch them together, to create a solar eclipse “movie.”
News from this year
Coming Soon: 2017 Total Solar Eclipse Movie
Eclipse Will Have Atmospheric Impact
On August 21, outside of Lusk, Wyoming, Terry Bullett and Justin Mabie, like thousands of others across the United States, will be watching the solar eclipse cross the sky above. Totality there will last for less than two minutes, starting at 11:46 am. But Bullett and Mabie will be watching the eclipse with more than just their (appropriately protected) eyes: They’ve set up instruments in a field outside of Lusk to take research radar measurements before, during, and after the eclipse. Information captured by their instrument will help them study the ionosphere, a part of the upper atmosphere that’s critical for radio and other forms of communications.
Ozone Treaty Taking a Bite Out of US Greenhouse Gas Emissions
The Montreal Protocol, the international treaty adopted initially to protect and ultimately to heal Earth’s protective ozone layer, has significantly reduced emissions of ozone-depleting chemicals from the United States. But in a twist, a new study by NOAA and CIRES scientists shows the 30-year old treaty has also significantly reduced climate-altering greenhouse gas emissions from the United States.
Soil Doesn’t Forget
Ecologists need to understand what and where soil microbes live in Earth’s ecosystems—these microorganisms can influence what can thrive above. But there’s a gap in the field: Today’s climate conditions do not fully explain the types of microbes they see. So CIRES researchers at the University of Colorado Boulder are looking thousands of years back in time—and they’re finding answers.
Alaska’s North Slope Snow-Free Season is Lengthening
On the North Slope of Alaska, snow is melting earlier in the spring and the snow-in date is happening later in the fall, according to a new study by CIRES and NOAA researchers. Atmospheric dynamics and sea ice conditions are behind this lengthening of the snow-free season, the scientists found, and the consequences are far reaching—including birds laying eggs sooner and iced-over rivers flowing earlier.
Two Degrees F Already Baked In
Even if people could instantly turn off all our emissions of greenhouse gases, the Earth would continue to heat up about two more degrees Fahrenheit by the turn of the century, according to a sophisticated new analysis published in Nature Climate Change. And if current emissions continue for 15 years, odds are good that we’ll see nearly three degrees (1.5 C) of warming by then.

High-Altitude Aircraft Data May Help Improve Air Quality Models, More
Sulfur dioxide released from volcanoes or power plants causes acid rain and leads to particles that play a role in breaking down the protective ozone layer high in the atmosphere. But those particles also reflect sunlight away from Earth, leading some to propose that people could inject sulfur dioxide (SO2) high in the atmosphere to mitigate global warming.
Modern River Piracy
The retreat of a massive Yukon glacier a mile up its valley has redirected meltwater from one river basin to another in the first modern case of “river piracy,” according to a new analysis by a team of researchers including Mike Willis, an assistant professor at the University of Colorado Boulder.

Sea Ice Hit Record Lows in November
Unusually high air temperatures and a warm ocean have led to a record low Arctic sea ice extent for November, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. In the Southern Hemisphere, Antarctic sea ice extent also hit a record low for the month, caused by moderately warm temperatures and a rapid shift in circumpolar winds.
On October 1, top chemistry researchers from around the country came to Missoula, Montana, to light stuff on fire. They converged at an old building that looked like a mad scientist’s warehouse. Inside, they helped each other set up millions of dollars worth of instruments. Wind tunnels weaved in and out of the walls, and a rickety elevator ferried researchers to the top of a giant smoke funnel. These scientists were kicking off a multi-year mission called FIREX—Fire Influence on Regional and Global Environments Experiment, to better understand the air quality and climate effects of fire—in the controlled environment of the Forest Service’s Rocky Mountain Research Station Fire Sciences Laboratory (Fire Lab).

By dissecting the sloshing signals of ocean tides recorded by magnetic satellites high above the Earth, a team of international researchers has managed to produce interior images of our planet, the scientists reported today in the journal Science Advances. Their proof-of-concept work could transform scientists’ ability to image and understand what lies below Earth’s crust, and could even help them remotely probe the interiors of other celestial bodies with tidal saltwater, such as Jupiter’s moon Europa
Wastewater Injection and Induced Seismicity
An increase in earthquake activity is occurring in areas of the eastern and central U.S., areas where unprecedented volumes of wastewater, produced along with oil and gas, are being disposed of, by injection, into deep geological formations. A new study, out today in Science, provides strong evidence of the link between oil and gas wastewater disposal and earthquakes in Texas.
Losing Its Cool
Measuring just how much mass a glacier is losing—through melting and calving—is no easy task. While there’s plenty of satellite data from space, scientists haven’t had access to much local, on-the-ground observation, which is the sort of information that’s necessary to more accurately measure glacial mass loss. But now a team of scientists, including CIRES’ Mike Willis, have put a series of GPS systems in place that give them the kind of data they need. Using that information, they find that previous estimates of mass loss from the Greenland Ice Sheet—already known to be shrinking—may be underestimates.
2016 Ties 2007 for Second Lowest Arctic Sea Ice Minimum
The Arctic’s ice cover appears to have reached its minimum extent on September 10, 2016, according to scientists at the National Snow and Ice Data Center, part of CIRES and CU Boulder. Arctic sea ice extent on that day stood at 4.14 million square kilometers (1.60 million square miles), statistically tied at second lowest in the satellite record with the 2007 minimum
Indigenous Knowledge at International Data Week
Welcome to the first ever International Data Week! This event, which runs September 11-17, brings together data scientists, researchers and policy makers in exploring how to take advantage of the data revolution and use all that information to benefit society. Among the participants this year is the Exchange for Local Observations and Knowledge of the Arctic (ELOKA).
Preventing Human-Caused Earthquakes
While the earthquake that rumbled below Colorado’s eastern plains May 31, 2014, did no major damage, its occurrence surprised both Greeley residents and local seismologists. The earthquake happened in an area that had seen no seismic activity in at least four decades, according to a new analysis by a team of Colorado researchers. It was likely caused by the injection of industrial wastewater deep underground—and, the team concluded, quick action taken by scientists, regulators, and industry may well have reduced the risk of of larger quakes in the area.
Putting Science to Work
Using seed grant money from CU, CIRES' WWA is working with Earth Lab to develop workshops and a class on usable science. With usable science, scientists have a better understanding of how their research will be used and the people using the research have their needs addressed. Essentially, it’s more about shaping the research agenda with those who are affected by a particular issue, rather than just handing them the results of a study.

North Dakota’s Bakken Oil and Gas Field Leaking 275,000 Tons of Methane per Year
The Bakken oil and gas field is leaking a lot of methane, but less than some satellites report and less than the latest Environmental Protection Agency inventory for petroleum systems, according to the researchers’ calculations. That's the finding of the first field study measuring emissions of this potent greenhouse gas from the Bakken, which spans parts of North Dakota and Montana. The work was published today in the Journal of Geophysical Research: Atmospheres.
World’s Shallowest Slow-Motion Earthquakes Detected Offshore of New Zealand
Research published in the May 6 edition of Science indicates that slow-motion earthquakes or “slow-slip events” can rupture the shallow portion of a fault that also moves in large, tsunami-generating earthquakes. The finding has important implications for assessing tsunami hazards. The discovery was made by conducting the first-ever detailed investigation of centimeter-level seafloor movement at an offshore subduction zone.

Islands Face A Drier Future
In a new study published in the journal Nature Climate Change, a new way of modeling the effects of climate change on islands shows that previous analyses underestimated the number of islands that would become substantially more arid by mid century–73 percent, up from an estimate of 50 percent. That puts an increasing amount of pressure on millions of humans and vital ecosystems that are both facing the brunt of the effects of climate change and underrepresented in global climate models.
Rethinking Induced Seismicity
A survey of a major oil and natural gas-producing region in Western Canada suggests there may be a link between induced earthquakes and hydraulic fracturing, not just wastewater injection, according to a new report out this week in the journal Seismological Research Letters.
