2013 Is the Fourth Hottest Year on Record

By Phil Plait (Slate):  It’s official: 2013 is the fourth hottest year since records started being kept in 1880. It ties with 2003 for that dubious honor. This result was just announced by the National Oceanic and Atmospheric Administration. It uses global annual land and sea surface temperatures to make the call, and in 2013 these two measures combined…

Arctic Sea Ice Minimum Volumes 1979-2013

Published on YouTube Nov 21, 2013: This is an animated visualization of the startling decline of Arctic Sea Ice, showing the minimum volume reached every September since 1979, set on a map of New York with a 10km grid to give an idea of scale. It is clear that the trend of Arctic sea ice…

Climate change the state of the science (data visualization)

Published on YouTube Nov 19, 2013: Produced by the International Geosphere-Biosphere Programme and Globaia and funded by the UN Foundation. The data visualization summarises and visualizes several of the most significant statements in the Intergovernmental Panel on Climate Change’s (IPCC) recent Fifth Assessment Report, (Working Group I summary for policymakers, the Physical Science Basis). In…

NASA: IPCC Projections of Temperature and Precipitation in the 21st Century

Published on YouTube Sep 27, 2013: New data visualizations from the NASA Center for Climate Simulation and NASA’s Scientific Visualization Studio show how climate models — those used in the new report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) — estimate how temperature and precipitation patterns could change throughout the 21st century.…

Arctic Death Spiral – Evolution to July 2013

Published on YouTube Aug 12, 2013: This is a visualization of the Arctic Death Spiral showing the evolution of the volume of sea-ice over time from 1979 to July 2013. Pitch of the notes are proportional to the average sea-ice volume for each month. Spectral filters are derived from the average sea-ice volume for each…

NASA: Wildfires, Smog – Particulate Matter Will Only Get Worse (August 2013)


August 10, 2013 – NASA Research is showing due to the increase in the earth’s temperature, we can expect to see more wildfires, and fires in areas that normally don’t see fires. NASA scientists talked to The Weather Channel about the latest research.

NASA: Potential Evaporation in North America Through 2100 (August 2013 in HD)

Published on Aug 9, 2013 by NASA: This animation shows the projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

NASA: Arctic Ocean Currents Changed

The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water in the…
