Glacial moulin formation triggered by rapid lake drainage

Scientists are uncovering the mystery of how, where and when important glacial features called moulins form on the Greenland Ice Sheet. Moulins, vertical conduits that penetrate through the half-mile-deep ice, efficiently funnel the majority of summer meltwater from the ice surface to the base of the ice sheet.

Image of Porcupine caribou herd travels cross country

There are no photographs of bison spilling by the thousands across the Great Plains. By the time cameras came along, most of the bison were gone. John Wright of Fairbanks believes he has an Alaska version of what that photo might have been.

Dr. Richard Alley’s Amazing Talk at the Annual Meeting of the American Meteorological Society is a Must Watch

I’ve been at the AMS Annual Meeting all week and as always it was an adventure in learning in so many ways. My highlight was seeing two good friends become Fellows of the Society. Those in the Detroit area are lucky to have Paul Gross (at  WDIV) and those in Columbia are lucky to have Jim Gandy (at WLTX). They are two of the finest broadcast meteorologists in the country. …

People return to flawed places because they do

As a child, Deb Long spent many hours at the post office in Ester, Alaska. Her mother Ruth was the postmaster there. As an adult, she has settled into a funky little house that stands on brick legs in the Holy Cross section of New Orleans.

Organic aerosols in remote areas have shorter lives than scientists assumed

Scientists find the lifetime of organic aerosols in the upper atmosphere is on the order of 10 days, far shorter than scientists previously assumed.

High-resolution climate models present alarming new projections for U.S.

Researchers have developed new, high-resolution climate models that may help policymakers mitigate the effects of climate change at a local level.

Driven by open ocean, Arctic continues to warm

“The Arctic shows no sign of returning to the reliably frozen state it was a decade ago,” said Jeremy Mathis, an oceanographer with the Pacific Marine Environmental Lab in Seattle.

Take Three Minutes and Study These Two Graphs

One of the biggest science meetings on the planet is underway in New Orleans right now. The AGU meeting is huge and a LOT of newsmaking science comes out of it. This year is no different. The AMS published a special edition of the Bulletin of the American Meteorological Society (BAMS) to coincide with this conference and the AMS annual meeting that I’m looking forward to attending in Austin next month. …

Consensus Matters- The Research Says So!

Those of us in science communication can be forgiven for thinking that everyone knows that agreement among scientists on climate change is extremely high. (It’s around 97-99% and the 1-3% who disagree have substantially less experience/publications in the field than the consensus group.) The Hard Truth The hard reality though is that most Americans have no idea the consensus is that strong and it makes one think that if we could …

Cartogram maps provide new view of climate change risk

Scientists have developed cartograms — maps that convey information by contorting areas — to visualize the risks of climate change in a novel way.

The Ten Mile Time Machine

I flew to the middle of the Chesapeake Bay Tuesday to visit Tangier Island. It’s just a 25-minute ride on the WBOC Chopper, and one of the most beautiful rides I’ve ever had in Chopper 16 (Yea, and I get paid to do this!). We made the trip to do a quick story on the new (much needed automated (AWOS3) weather station, and the photos are mine. (I’ve added the video …

Everyone Fights Confirmation Bias, but Science Teaches You How To Win the Battle.

Read the comments on any news story, and you get a free lesson on confirmation bias. This error in thinking strangles our ability to analyse information and make rational decisions. Doctors see it in patients that refuse vaccines for their children and waste money on homoeopathic sugar water in fancy bottles. Vitamin salesman, astrologers, and naturopaths rely on it for a living. It’s also responsible for the anger (rather than the thanks) …

Defending U.S. Government Employed Earth and Space Scientists

Earth and space scientists work in key positions throughout the federal government. As civil servants, atmospheric scientists at NOAA, seismologists at the USGS, and hydrologists at the EPA– and frankly all other agency scientists – work to help fulfill their agencies’ missions and safeguard the health, economy, and security of all Americans. That’s why it’s so troubling to witness measures taken by some agencies to silence or even discredit federal …

Attribution Study Shows Hurricane Harvey Floods Becoming Much More Likely

Check out this paper in PNAS today. When the subject of hurricane experts comes up, there are two names that come into the mind of nearly every meteorologist: Kerry Emanuel and Chris Landsea. There are a lot of others, but these two have published a lot of research that gets sourced frequently. Today Kerry Emanuel has what can be called an attribution study on Hurricane Harvey. These studies look at how …

Study: Major return on investment from improving climate observations

A well-designed climate observing system could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits by providing decision makers information they need to protect public health and the economy in the coming decades, according to a new study published today.

New approach to geoengineering simulations is significant step forward

Using a sophisticated computer model, scientists have demonstrated for the first time that a new research approach to geoengineering could potentially be used to limit Earth’s warming to a specific target while reducing some of the risks and concerns identified in past studies, including uneven cooling of the globe.

New Climate Report- Humans Are Warming The Planet; There’s No Convincing Evidence for ANY Other Cause

  The 4th U.S. Climate Assessment is HERE. A summary is here. Here are some key findings. I want to highlight what I think is the key finding: This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century. For the warming over the last century, there is no …

4th U.S. National Climate Assessment: Reinforcing the Scientific Consensus

Volume 1 of the Congressionally mandated 4th U.S. National Climate Assessment (NCA) was released earlier this month. Led by scientists working at NOAA, the Climate Science Special Report (CSSR) is the work of many of the nation’s most accomplished climate scientists. Used as a core blueprint used to inform the public and craft public policy decisions to address climate change, the report is a rigorously evaluated document that has gone …

When Jerry Brown came to Nome

The California governor was stopping in Nome on his way to a meeting in Russia. The 79-year-old environmentalist and leader of a state that resembles a progressive nation wanted to learn why the far north matters. He had never been to the Arctic or Alaska before.
