Global warming in one unmistakably compelling chart

Global warming in one unmistakably compelling chart | Développement durable et efficacité énergétique | Scoop.it
If you have any doubt the balance of the globe has warmed over the last century, view this chart.


Produced by NASA, the chart illustrates how temperatures have compared to “normal” from 1880 to present, from pole to pole.

From the 1880 to the 1920s, blue and green shades dominate the chart, signaling cooler than normal temperatures in that era.  Then, from the 1930s to the 1970s, warmer yellow, oranges, and reds shades ooze in, balancing the cooler shades.

The rapid warming at the northern high latitudes especially jumps out in recent decades, reflecting “Arctic amplification” or more intense warming in the Arctic.  Although the warming is most pronounced up north, it is apparent at almost every latitude.

But since the 1970s, the blue and green shades rapidly erode and oranges and reds take over, dramatically.

Global warming facts!

Owen Roberts, BSc, MBA's curator insight, September 23, 2013 8:16 AM

GLOBAL WARMING - Here is an chart developed by NASA that shows how much global temperatures have changed during the last 140 years.  Quite compelling. 

Hein Holthuizen's comment, September 29, 2013 4:00 AM
There is no doubt about an general increase of temperature. Whether it is worrysome is not to be seen on this small scale. We had colder periodes like ice ages and now we are likely in a interglacial. So global temperatures change over time. Nice picture btw.

Visualizing 100 Years Of Climate Data

Visualizing 100 Years Of Climate Data | Développement durable et efficacité énergétique | Scoop.it

What does 100 years worth of climate data look like when rendered in an interactive, color-coded map? A continental tug-of-war between red (for heat) and blue (for cold), as seasons come and go and cold air replaces the warm.

The infographic is the work of data visualization studio Halftone, whose principals originally pursued the idea of making a map to visualize data about coffee production against key environmental factors, like temperature and precipitation.

 

"Our goal with this project was not to facilitate precise analysis, but to expose how every single month produces a unique and beautiful artwork through our Voronoi tessellated approximation of a heat map," write the creators. "The underlying map of satellite imagery and major geographic features adds a second layer for exploration."

The World as 100 People / Infographic

The World as 100 People / Infographic | Développement durable et efficacité énergétique | Scoop.it

A demographic portrait of humanity if the world were 100 people.

 

From data source, 100people.org:

The world population has now reached 7 billion people. This milestone inspired us to conduct research to update our statistics, and the changes over the past 5 years are remarkable. In 2006, only 1 person out of 100 would have had a college education-- today that number has jumped to 7 thanks in part to advances in higher education in Asia. The detailed research and source information can be found here and the statistics provided by Donella Meadows in 1990 that originally inspired our project can be viewed here.

Climate Change and Human Responsibility

Climate Change and Human Responsibility | Développement durable et efficacité énergétique | Scoop.it
It can’t be denied any longer: Sea levels are rising, major droughts are continuing, and record hot summers are being experienced all around the world. Climate change is real and, as residents of Earth, we have a responsibility to our planet to do something about it. A recent study conducted by Yale University and George Mason University finds that, for the first time since the research began in 2008, the majority of Americans believe that global warming is mostly a man-made phenomenon.

As sobering images of catastrophes are making headlines, this graphic looks at how people are recognizing that the effects of their actions aren’t just an increasing danger to the world but are a direct threat to the future for themselves and their families.

Visualizing How New York City Heats Up In The Summertime

Visualizing How New York City Heats Up In The Summertime | Développement durable et efficacité énergétique | Scoop.it

If you find the summer heat hard to take, cities are the worst places to be. Studies show that urban spaces can be up to three degrees hotter than surrounding areas. That's because of the "heat island effect"--which is what you get from paving every available surface with heat-absorbing asphalt and concrete.

 

Using a thermal camera, these graphics by artist-researcher Nickolay Lamm explain how a city gets hot and stays hot.

Stunning Satellite Images of Earth

Stunning Satellite Images of Earth | Développement durable et efficacité énergétique | Scoop.it

Of all the cosmic bodies studied in the long history of astronomy and space travel, the one that got the least attention was the one that ought to matter most to us—Earth.

That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Landsat was built for public monitoring of how the human species was altering the surface of the planet. The space agency, along with the U.S. Geological Survey (USGS), has accumulated a stunning catalog of images that, when riffled through and stitched together, create a high-definition slide show of our rapidly changing Earth, which for the first time date all the way back to 1984.

 

These Timelapse pictures tell the pretty and not-so-pretty story of a finite planet and how its residents are treating it — razing even as we build, destroying even as we preserve.

Watch 62 Years of Global Warming in 13 Seconds

Watch 62 Years of Global Warming in 13 Seconds | Développement durable et efficacité énergétique | Scoop.it

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.

World Supplies of Non-Renewable Resources, Visualized [Environmental Infographic]

World Supplies of Non-Renewable Resources, Visualized [Environmental Infographic] | Développement durable et efficacité énergétique | Scoop.it

Politicians and oil companies might waste time debating whether or not we’ve reached peak oil. What they ignore is that we run out completely in under 40 years’ time, by which time a third of the planet’s biodiversity will be lost.

In the meantime, tantalum, that great mainstay of mobile telecoms, will last only a few years more and run out just in time to celebrate the planet breaking the 2oC barrier in 2060.
There’s so much more words could say, but this, a very relevant and informative environmensl visualization, says is so much better...

For all its good intentions, the environmental movement has historically been plagued by aesthetic ineptitude.

AN : As the TED Talks exhibit on the integration of Technology, Entertainmernt and Design, the overlap of design principles to technology goes a long way to communicating the message, importance, implications and impact of the technology. Great thought provoking short piece from the FastCoExist publication which Sustain Our Earth scooped on their site.
