Watch 62 Years of Global Warming in 13 Seconds

Watch 62 Years of Global Warming in 13 Seconds | Digital Sustainability |

An amazing 13-second NASA animation depicting how the globe has warmed during the period of 1950 to 2012.

From our friends at NASA comes this amazing 13-second animation that depicts how temperatures around the globe have warmed since 1950. You’ll note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.


The data come from NASA's Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures. As NASA notes, “All 10 of the warmest years in the GISS analysis have occurred since 1998, continuing a trend of temperatures well above the mid-20th century average.

Why we should care about global warming. And keep working on solutions (they exist).

When Charles Keeling first began measuring the atmosphere’s carbon dioxide levels in the late 1950’s, he noted first that they stood at about 315 parts per million (ppm), or 315 molecules of carbon dioxide for every million molecules of air.

Soon after, though, he found that the concentrations were rising, thanks to the burning of fossil fuels (today, they stand at around 395 ppm and they’re still rising). But he also noticed that the upward curve of CO2 concentrations had a sawtooth pattern. That pattern saw CO2 rise sharply in the fall in the Northern Hemisphere -- when leaves died and fell off the trees to rot -- then drop slightly in spring as new leaves emerged to start drawing in CO2 for photosynthesis. (Leaves fall and sprout in the Southern Hemisphere, too, in an exactly opposite pattern, but there’s so much more ocean and so much less land south of the Equator that the Northern effect is a lot stronger).

Now NASA has put together an animation that shows this process in a much more vivid way. Based on observations from two instruments on the Aqua spacecraft, the animation shows how the disappearance of leaves (green) leads to an increase in atmospheric CO2 (yellow-orange), first in one hemisphere, then in the other — and just as Keeling showed a half-century ago, the effect in the Northern Hemisphere is a lot stronger.

Cada año desde 1976, la NASA ha publicado una lista de todas las tecnologías y productos comercializados vinculados a su investigación. La revista de la NASA “Spin-off“ pone de manifiesto que estos productos han incluido mejoras en marcapasos, en el estado de las máquinas de ejercicio o en la radio por satélite. Cada producto ha sido posible gracias a una idea de la NASA o a la innovación por parte suya.
