Bolivia has officially declared that their second-largest lake, Lake Poopó, has disappeared. While long-term water diversion for mining and agricultural use has been cited as a partial culprit, an El Niño-driven drought, along with the disappearance of the Andean glaciers that fed the lake, are being blamed for the lake’s disappearance.

While Lake Poopó’s size historically sees large fluctuations due to it’s relative shallowness, this is the first time it has essentially disappeared, now being at only 2% of it’s former maximum water level of 5 meters (16.4 feet). A recent study showed that the water the lake received in 2013 wasn’t enough to maintain it’s equilibrium, short by 161 billion liters (42.5 billion gallons).

The National Aeronautics and Space Administration has released an animation on their website that illustrates how average global surface temperatures have risen since record-keeping started in the late 19th century. The video helps to visually illustrate the rise of Earth’s temperatures, spanning a 135-year period from when temperature records were first recorded, in 1880, through 2015, the hottest year on record.

The baseline average used in the video was derived from temperature averages from 1951 through 1980, with blue colors representing below-average trends, and orange representing above average temperatures.

The National Oceanic and Atmospheric Administration also released a similar video, showing the same warming trend over the past 135 years. read more

hidden was solved when it was found that it was being trapped deep in world’s oceans. While this had granted us a minor reprieve in the otherwise measurable increase in the atmosphere’s temperature, a new study has shown to what extent the ocean’s heat-absorbing ability has been helping us.

Earlier this month, the North Atlantic experienced a rare January hurricane, named Hurricane Alex. While Alex’s northward track kept it in the middle of the Atlantic Ocean, it’s arrival in the waters south of Greenland coincided with a sudden outflowing of meltwater through a bay in the Western Greenland, indicating that the warm winds that accompanied Alex had triggered a melting event.
