A new study of algal bloom activity in dozens of freshwater lakes around the world provides an answer: For the past 30 years, lakes nearly everywhere have been experiencing more frequent and severe toxic algal blooms—and a changing climate is one reason why.
Researchers at the Carnegie Institution for Science used satellite data collected over the past three decades to examine large freshwater lakes across six continents. They searched through more than 72 billion data points to identify statistically significant patterns in algal bloom intensity and found that the severity of algal blooms has increased in over two-thirds of the 71 large lakes studied across 33 countries.

Species Unseen For 47 Years Rediscovered Near Colombian Town Named For Miracles. Fewer than 20 Antioquia Brushfinches are known, and habitat is under immediate threat.
The Antioquia Brushfinch was first described by ornithologist Thomas Donegan in 2007, after a review of brushfinch specimens in South American and European collections. Donegan noticed three specimens labeled from San Pedro de los Milagros and “Antioquia” generally that were marked as representing the widespread Slaty Brushfinch, but looked different. Two of these specimens were undated, and one was collected in 1971. Many feared that the species “discovered” in the museum drawers was extinct, after several searches over the last 12 years failed to find it.
