NASA Picture of the Day, Global Warming: 130-Year-Compilation Of Earth's Climate [PHOTOS] [VIDEO]
NASA compiled 130 years worth of images of temperature records from over 1000 weather stations around the globe, and combined them with modern satellite data to track global temperature rise.
The video below dramatizes the result, showing 130 years of planet-wide temperature change relative to the local average temperatures in the mid-1990's. A reddish tint indicates that the area was warmer than the global average that year, and blue means the converse.
On average, the display demonstrates that the temperature on Earth has increased by nearly one degree Celsius over the past 130 years. As indicated in the video below, many of the warmest years on record have only occurred recently. Towards the end of the compilation, orange and red is abundant, marking higher-than-average global temperatures.
Global warming has already begun to affect our planet. While many climate scientists project over-the-top effects, such as the ocean completely evaporating into the atmosphere, current changes are difficult to ignore.
A recent photo by the North Pole Environmental Observatory features the North Pole, formerly a block of rigid ice, has turned into a slushy lake. The photo can be viewed here.
