Incredible shots tweeted by the rock-star astronaut from the International Space Station
Wow. Absolutely must see.
Chris Hadfield’s Mission Reflections.
I’m going to make a real effort to have a beer/30 minute convo with this man by the end of 2014. Committed!
If you are wandering around Greenland’s ice sheet and you run into this crazy thing, it is NASA’s GROVER (
government acronym for somethingGoddard Remotely Operated Vehicle for Exploration and Research). It is solar powered and it crawls around Greenland on its own and uses ground-penetrating radar to look at ice. And it’s cool.
NASA robot explores ice in Greenland. Video. Will explore for months at a time via remote. Possibly prototype to explore other planets.
Some Strange Things Are Happening To Astronauts Returning To Earth
Tremendous. Surprise ending.
The fire maps show the locations of actively burning fires around the world on a monthly basis, based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The colors are based on a count of the number (not size) of fires observed within a 1,000-square-kilometer area. White pixels show the high end of the count —as many as 100 fires in a 1,000-square-kilometer area per day. Yellow pixels show as many as 10 fires, orange shows as many as 5 fires, and red areas as few as 1 fire per day. Via EO NASA
Cruise over glaciers in Greenland. Researchers use aerial footage for data collection and monitoring.
Few of us ever get to see Greenland’s glaciers from 500 meters above the ice. But in this video — recorded on April 9,2013 in southeast Greenland using a cockpit camera installed and operated by the National Suborbital Education and Research Center, or NSERC — we see what Operation IceBridge’s pilots see as they fly NASA’s P-3B airborne laboratory low over the Arctic.
Following a glacier’s sometimes winding flow line gives IceBridge researchers a perspective on the ice not possible from satellites which pass in straight lines overhead. By gathering such data, IceBridge is helping to build a continuous record of change in the polar regions.

Climate Change Shifts North’s Growing Seasons
temperature and vegetation growth at northern latitudes now resemble those found 4 degrees to 6 degrees of latitude farther south as recently as 1982.
“Higher northern latitudes are getting warmer, Arctic sea ice and the duration of snow cover are diminishing, the growing season is getting longer and plants are growing more,” said Ranga Myneni of Boston University’s Department of Earth and Environment. “In the north’s Arctic and boreal areas, the characteristics of the seasons are changing, leading to great disruptions for plants and related ecosystems.”
Image: Of the 10 million square miles (26 million square kilometers) of northern vegetated lands, 34 to 41 percent showed increases in plant growth (green and blue), 3 to 5 percent showed decreases in plant growth (orange and red), and 51 to 62 percent showed no changes (yellow) over the past 30 years. Satellite data in this visualization are from the AVHRR and MODIS instruments, which contribute to a vegetation index that allows researchers to track changes in plant growth over large areas.
Soon, governments and citizens alike will be able to spot illegal loggers from space. A new tool called Global Forest Watch 2.0 will give anyone with a computer or smartphone the ability to zoom in on forests around the world and spy on illegal cutting operations in near-real time.
“Global Forest Watch 2.0 aims to transform access to information about what’s happening to forests everywhere around the globe,” says Nigel Sizer, the director of the World Resources Institute’s Global Forest Initiative in Washington, D.C. “The platform allows people to see those numbers—how much clearing is done year by year in oil concessions in Indonesia, for example, or by a cattle ranch in the Brazilian Amazon—without involving training in technology or science.”
The open-access online monitoring platform, which will include two major data sets when it launches in the first half of 2013, combines satellite technology, data sharing and social networks to combat deforestation.
The first dataset, provided by the NASA MODIS system, is updated every 16 days. Over that same period, algorithms compute the likelihood that any given 250-square-meter patch of forest has been cleared based upon the remote-sensing imagery. Higher spatial resolution data, provided by the University of Maryland, will be added annually. The platform relies upon cloud computing for storing the massive datasets involved in visualizing and processing the maps.

NASA and the Department of the Interior’s U.S. Geological Survey (USGS) have released the first images from the Landsat Data Continuity Mission (LDCM) satellite, which was launched Feb. 11.
The natural-color images show the intersection of the United States Great Plains and the Front Range of the Rocky Mountains in Wyoming and Colorado. In the images, green coniferous forests in the mountains stretch down to the brown plains with Denver and other cities strung south to north.
LDCM acquired the images at about 1:40 p.m. EDT March 18. The satellite’s Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) instruments observed the scene simultaneously. The USGS Earth Resources Observation and Science Center in Sioux Falls, S.D., processed the data.
LDCM is the eighth in the Landsat series of satellites that have been continuously observing Earth’s land surfaces since 1972.
Scientific consensus on climate change is at 97%, which might be the highest agreement among any of the sciences.
“10 Ways the Sequester Will Expose Americans to Greater Health Risks and Other Perils”. That link-baity headline is the intro to a slew of alarmist clap-trap from the: Center for American Progress (CAP).
The truth is, it is not known which programs or projects will be cut as a result of sequestration. Ezra Klein of the Washington Post has a much more reasonable take on Congress’s inaction (unlike CAP, Klein seems to have read and comprehended the Budget Control Bill):
The sequester is set to cut spending across the board. But how? We know an awful lot about what the sequester can’t do. It can’t cut Social Security, Medicaid, military salaries or any number of of exempt programs. It can’t mess with federal pay scales. It can’t favor certain programs over others. But the actual process by which cuts are to be determined, and who is involved in that process, is more obscure.
The problem, budget experts say, is that the Budget Control Act was simultaneously very strict in its dictates and not specific about what those dictates mean. “The law states that the ‘same percentage sequestration shall apply to all programs, projects, and activities within a budget account,’ ” former OMB director Peter Orszag says. “That’s pretty restrictive, giving little room for creativity.”
What room there is comes from defining exactly what is meant by “programs,” “projects” and “activities.” “There is not a standard definition,” Stan Collender, a longtime Congressional budget hand currently at the PR firm Qorvis, explains. “It’s not something that exists anywhere else in nature.”
I struggled deciding to post this video on Communicating climate science to the public. But I opted to post it anyway to show that it is totally OK to criticize experts in your own field.
The video is not dated, despite that Columbia University hosted this event back in 2010. The issues discussed really are relevant today.
Three distinguished scientists walk you through the issues and challenges of communicating climate science to the public:
- Gavin Schmidt, climate modeler at the NASA Goddard Institute for Space Studies, co-founder of the blog Real Climate.org, and co-author of a popular science book Climate Change: Picturing the Science.
- Ned Gardiner, Climate Visualization Project Manager at the National Oceanic and Atmospheric Administration (NOAA)’s Climate Program Office.
- Sabine Marx, Managing Director at the Center for Research on Environmental Decisions (CRED) at Columbia University.
The first panelist, Gavin Schmidt, who is utterly brilliant on RealClimate.org, is flat, rambling, and just plain boring. I learned nothing from him other than his contempt for politicians, which is both repulsive for a scientist and ironic to convey considering he’s advocating communicating with them.
Gardiner brings up the fact that most Americans are terrible at reading and understanding basic charts and graphs, for example, which makes communication really difficult for the scientist. Good point, but he doesn’t provide a solution.
And that’s basically how I felt throughout the entire hour+ while watching this - smart people discussing simplified themes with contempt for the public and the politicians they (we) voted to represent us.
True, the panelists are experts in their fields. They are revered, credentialed scientists with public personas. This brings much needed credibility to the conceptual problem of communicating science to the public. But they don’t do a great job of explaining the difficulties of communication, nor do they provide tested examples with any sort of stickiness. Gardiner dances around this issue of getting scientific concepts to stick, and he points to the media’s lack of scientific understanding. But he just misses his opportunity to nail his points home with any clarity.
My gut thinks this talk was rather generic and vague and overall does a disservice to the important concept of communicating science.
You might be asking: If Michael is so sour on this talk, why did he even post it? I think it’s to show that even experts in communications struggle with the issue of communicating science with the public. For example, their personal biases shade their overall points.On the one hand, they want their fellow scientists to make greater efforts to communicate with politicians. On the other, the panelists spent several minutes completely dismissing and condescending those very same politicians.
And maybe that’s my secondary point of posting this. That critical thinking is required when watching these talks. Just because someone is respected in their field doesn’t mean that they’re any good at advocating for change. In other words, it’s OK to be critical of the critics…
It’s Climate Science Communications Week at Climate Adaptation! For the entire week of Feb. 18 - 23, I’ll cover how climate change is discussed by the media, scientists, researchers, academics, and politicians.
