All the Rivers in the U.S. on a Single Interactive Map

All the Rivers in the U.S. on a Single Interactive Map | Sustain Our Earth | Scoop.it

A recent report by the U.S. Environmental Protection Agency concluded that 55 percent of U.S. rivers and streams are in poor condition. Many of us might not realize just how many rivers and streams there are in the United States.

This map gives you an idea of how many there are; visit the link to see many beautiful different visualizations of rivers in the U.S., as well as an interactive map that you can play with and zoom in and out of to see the rivers in your area.

All river data comes from the NHDPlus dataset, a geo-spatial, hydrologic framework dataset envisioned by the US Environmental Protection Agency.

Global warming in one unmistakably compelling chart

Global warming in one unmistakably compelling chart | Sustain Our Earth | 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.

Watch 62 Years of Global Warming in 13 Seconds

Watch 62 Years of Global Warming in 13 Seconds | Sustain Our Earth | 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.

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

Victoria McNamara's curator insight, December 11, 2013 11:28 AM

By looking at this data sheet you can see that the worlds population will increase by the millions in 2050. These populations will increase in areas that are already very populated and in areas that are not so heavily populated yet. 

Lona Pradeep Parad's curator insight, May 28, 7:00 PM

This is an interactive map where you can click the year you wish and see what the population is or will be. it allows a person to observe and understand population growth better.

Katelyn Sesny's curator insight, October 31, 12:21 PM

A straightforward map that puts previous knowledge (of the rapidly growing population and the limited food supply) into prescriptive. -UNIT 2

Visualizing 100 Years Of Climate Data

Visualizing 100 Years Of Climate Data | Sustain Our Earth | 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."
