NASA releases “then-and-now” photos of Earth. The changes are shocking
By now everyone has heard about climate change, but these photos are as good an indicator as any that the differences just six years can make. These photos show the differences between the same places, with some photos taken in 2010 and then in 2016. You won’t believe just how different some of these locations look. One example is from Lake Oroville, California. Until very recently, most of the state of California was suffering from a serious drought, and Lake Oroville, California was a place that was hit hard by the lack of water. You will be amazed by the differences in each location.
Another example in this trending news story is the Pedersen Glacier in Alaska. The photo was taken in at the location during the summer of 1917, while the new photo of the same spot shows the summer of 2005. You can't help but notice the massive changes in the snow level during the same period. Then there is the photo from the Aral Sea located in Central Asia which has greatly dried up in comparison to the August 2000 photo. 2014 was a dry year, and this birds-eye view showcases just how small the sea has become.
Then there are the photos of Carroll Glacier, Alaska. The first one was taken in August 1906 with the latter photo taken in September of 2003; you will be amazed at the differences. It was a dry and hot season in 2014, and this photo showcases how dry Arizona and Utah were during that time. Powell Lake, Arizona, and Utah. March 1999 to May 2014. Then the photo of Great Man-Made River, Libya, April 1987 and April 2010. The man-made river in this location is known as one of the great engineering projects of the world. Through a serious of pipes, wells, and aqueducts, the water system provides the desert with water. Alaska has also become a lot warmer than in past years, and nothing showcases this more than the Muir Glacier. The difference makes these photos look like two completely different locations. August 1941 to August 2004. Uruguay has grown its forest areas. While this sounds positive, this has affected plant and animal diversity. Uruguay Forests, March 1975 to February 2009.
Climate change is the change in the statistical distribution of weather patterns when that climate change lasts for an extended period, from decades to millions of years. Climate change can also refer to a change in average weather conditions or in the time variation of weather around the longer-term average conditions. Climate change is caused by several factors such as biotic processes, plate tectonics, variations in solar radiation received by Earth, and volcanic eruptions. Some human activities have also been identified as major causes of recent climate change, often referred to as global warming. Scientists have to actively work to try and understand past and future climate by using observations and theoretical models. General circulation models, which are based on the physical sciences, are often used to match the past climate data, make certain future projections, and link causes and effects in climate change. Glaciers are considered among the most sensitive indicators of climate change. The size of a glacier is determined by a mass balance between snow input and melt output. As temperatures start to become warmer, glaciers retreat unless snow precipitation increases to make up for the additional melt. Therefore, an average must be taken over a decade or longer time-scale and over individual glaciers in order to smooth out the local short-term variability and obtain a correct glacier history that is related to climate.
