Why your carbon footprint is a scam, explained. Check out Climate Town here: https://www.youtube.com/c/climatetown?sub_confirmation=1 In this special Our Changing Climate video, I showcase Rollie at Climate Town’s video all about why your carbon footprint is a scam. Through this carbon footprint video,…

While the representation of physical processes in climate models has become more sophisticated over the last 30+ years, the vertical and seasonal fingerprints of Arctic greenhouse warming have not changed. Are the models right? Observations in recent decades show the same fingerprints:…

After general remarks about the state of climate science, with the one hopeful path of unwrapping its layers of complexity one by one with careful process studies, the scientific history of ocean-atmosphere interaction will be reviewed. The presentation will then focus on…

In 1922, Lewis Fry Richardson posed the dream of using a grid of prognostic equations to accurately compute future weather before it arrives. But while weather predictability has been realized, and despite tremendous improvements in computational speed and physical understanding, we have…

Planetary boundaries has emerged as a widely quoted conceptual framing for potential limits to the carrying capacity of the Earth, especially in policy disciplines. Yet in the original 2009 paper in Nature no planetary boundary for the carbon cycle was suggested. In…

Scientists are studying the St. Lawrence River to monitor its health. By researching key environmental indicators, we can assess how well the St. Lawrence ecosystem is doing. This research is an important part of the St. Lawrence Action Plan, a joint initiative…

Scientists are studying the Northern Gannet in order to better understand the health of the St. Lawrence ecosystem. Biologist, Jean-François Rail, discusses his research and what the scientific community has learned so far. This research is an important part of the St.…

Researching invertebrates in the St. Lawrence River helps scientists monitor the health of this important ecosystem. Biologist, Alain Armellin, discusses his St. Lawrence invertebrates research, and what the scientific community has discovered so far. This important research is an important part of…

Studying the water quality in the St. Lawrence River helps scientists learn about the health of its water and its important ecosystem. Dr. Caroline Anderson, limnologist, talks about her work and what the scientific community has found so far. This research is…

The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. It is the product of a partnership between NASA and…

Satellites have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. This visualization shows…

This movie shows the evolution of several regions of the Greenland Ice Sheet between 2008 and 2300 based on three different climate scenarios. Each scenario reflects a potential future climate outcome based on current and future greenhouse gas emissions. The regions shown…

Scientists from NASA’s Goddard Space Flight Center in Greenbelt, Maryland and international collaborators demonstrated a new method for mapping the location and size of trees growing outside of forests, discovering surprisingly high numbers of trees in semi-arid regions and laying the groundwork…

B-roll for media. The Sentinel-6 Michael Freilich is an Earth-observing satellite that will collect data on sea level and how it changes over time. By measuring sea surface height, scientists worldwide can monitor sea level rise, track climate patterns, improve hurricane forecasts,…

PACE is a climate observatory. With a collection of advanced sensors, PACE will study ocean color, aerosols, clouds, climate change, and other aspects of Earth’s overall health. The backbone of the mission is the satellite itself, providing data to a robust network…

Complete transcript: https://svs.gsfc.nasa.gov/vis/a000000/a004700/a004799/MethaneCaptionsenUS.en_US.srt The visualization presented here shows the complex patterns of methane emissions produced globally between January 2018 and November 2018 from different sources. Methane is a powerful greenhouse gas that traps heat 28 times more effectively than carbon dioxide over…
