So Imma tell you all a thing…on you should have figured out by doing a simple Google search, but this is another moment where someone on tumblr went “There Gulible written on the ceiling” and noone looked up, but everyone freaked out about it.
The first picture, everyone’s seen it, that note count tells us that, but did you know…its fake?
Thats right people, the first picture is from 2002, and then edited greener, and the second one? Taken specifically at a different angle and during the winter…when its noticeably more brown…dont believe me? here, have a link. DOnt have time to click the link? (kinda like not having time to look this up) Then heres the article!
A popular image heavily shared on social media websites shows two images of our planet, one dated 1978 and one dated 2012. The 1978 photo shows a much greener United States, while the 2012 image appears to be devoid of vegetation. The caption reads, “The same planet just 34 years after. Kinda sad, right?” Is this photo accurate?
The images are real, but they have been altered, and the caption is wrong.
Let’s take a look at these images a little closer. The original image being circulated looks like this:
The “1978″ Image
The image on the left, dated 1978, was actually taken on February 8, 2002. You can find the original image here, and the NASA page discussing it here. Thus the caption stating that it was taken in 1978 is incorrect. We have compared the alleged 1978 image (which we’ll now refer to as the 2002 image) with the original NASA photo below. The original NASA photo is on the left and the 2002 photo in circulation is on the right. You’ll see that the colors have been altered from the original to be more vibrant, and the subtle greens of the original are much brighter in the altered version.
The “2012″ Image
The photo dated 2012 in the circulated image was taken on January 24, 2012. The original can be found on the NASA website, here. Their description of the image reads:
A ‘Blue Marble’ image of the Earth taken from the VIIRS instrument aboard NASA’s most recently launched Earth-observing satellite – Suomi NPP. This composite image uses a number of swaths of the Earth’s surface taken on January 4, 2012. The NPP satellite was renamed ‘Suomi NPP’ on January 24, 2012 to honor the late Verner E. Suomi of the University of Wisconsin.
If we compare the original with the photo in circulation, we see that there is only slight color variation from the original.
This leads us to the original comparison, of what we now know to be images taken in 2002 and 2012 – only 10 years apart. How can we account for the discrepancy that does exist between the two images?
Comparing the colors of these photos, we see that the 2002 image has much more vibrant colors, perhaps altered after the fact, or due to other processes. Comparing the blue in the oceans in the two images reveals that the oceans in the 2002 image have a nearly purple tint. This alone could account for much of the discrepancy in color.
The 2002 image is clearly a different angle of North America than the 2012 image. This angle makes the continent appear significantly larger in the 2012 image.
It has been argued that the 2012 image has a “deforested” look because it was taken in the middle of winter when trees are likely to be bare, yet the 2002 was only taken a couple of weeks later in the year. It’s unclear whether the winter seasons in 2002 and 2012 were as different as the colors in these images may imply.
In short, the image being circulated does not show a comparison of North America in 1978 and 2012, but two very different images taken only 10 years apart.
Comparison of unaltered images
Below we have recreated the comparison, using the original unaltered images:
The photos in circulation were taken only 10 years apart and have been altered.
So there you have it! Another thing the people of tumblr should have fact checked, kinda like that radiation post that was actually tsunami perdictions (actually, someone probably looked it up but got deleted by those who dont care about actual facts and only like to find fault). SO yep, you have been informed and noone will probably even care because they get stuck in their ways….
