Wildlife refuge pond in Hawaii mysteriously turns bubble-gum pink after drought
Halobacteria thrive in bodies of water with high levels of salt. The salinity inside the Kealia Pond outlet area is currently greater than 70 parts per thousand, twice the salinity of seawater. Maui's drought is likely contributing to the situation. Normally Waikapu Stream feeds into Kealia Pond and raises water levels there, but Wolfe said that hasn't happened in a long time.

Corals in peril at a popular Hawaiian tourist destination due to global climate change
Researchers from the Coral Reef Ecology Lab at the Hawai'i Institute of Marine Biology documented the third global bleaching event as it occurred from 2014 to 2016 at the Hanauma Bay Nature Preserve (HBNP) on the island of O'ahu, Hawai'i. Their findings, published in the international journal PeerJ, show that temperature is by far the most influential factor in coral bleaching at this well-managed location where corals, fish, and all other organisms are protected.

North Saskatchewan River Turns Blue
The river, which starts at the Saskatchewan Glacier in the Columbia Icefields and flows through to central Saskatchewan, is usually murky brown by the time it reaches Edmonton in summer. In recent weeks, however, the water has taken on the hues of Alberta's glacial lakes, thanks to dry, hot weather combined with maintenance at a major dam.
