From climate change to wildfires, these images show just how much our planet has been altered

NASA images reveal just how much the Earth is changing

Monday, March 23, 2015, 10:35 GMT - Wildfires, flooding, climate change, the effect of man. These are just some of the reasons the world has been changing and now thanks to NASA we can visualise it.

The organisation uploaded hundreds of images that document the way in which the world has been changing.

By comparing one geographical location at two different times (whether that be months or years apart) it becomes clear just how much our planet has been altered.

Take a look at some of the images below:

"Drought in the 1970s spurred the formation of the multinational Organization for the Development of the Senegal River to develop irrigation, power generation and navigation. The Manantali Dam in western Mali was one of two large dams built as part of the OMVS project," NASA explains. "These images show the vast extent of land that was flooded when the dam's reservoir was filled."

The picture above shows the ice melt that occurred in the Alps between Italy and Swizerland. In 45 years, Matterhorn mountain went from being covered in snow to barely showing any white.

China is no stranger to major natural disaster. The above images show the dramatic change after the Dongting Lake flooded the Hunan province back in 2002.

The Muir Glacier is one of the biggest changes to affect Alaska in the last 63 years. The glacier virtually disappears in the pictures taken 10 years ago.

"A series of wildfires, triggered by lightning strikes during the weekend of August 21 and 22, 2010, burned more than 300,000 acres of sage and grasses in the south-central region of Idaho," NASA wrote on their website. "On August 23, the fire burned over 200,000 acres in a single day. Smoke from the fires dramatically impacted air quality in a number of local communities. "
