On Tuesday, June 6, a major hydroelectric dam on the Dnipro River in Ukraine was blown up, which will likely have devastating impacts not only on thousands of people and agriculture but also on ecosystems. While it remains unclear who bombed the 68-year-old Kakhovka dam, the flooding from the reservoir behind it threatened drinking water, irrigation, and hydropower. According to Reuters, hundreds of people had to be rescued from rooftops two days after the dam breach. It was reported that 13 people were killed and 30 were missing, as of June 11.

The National Oceanic and Atmospheric Administration’s Climate Prediction Center announced last week that El Niño is present and is likely to grow, affecting weather around the world and increasing the average global temperature. El Niño conditions bring unusually warm temperatures to the sea surface in the tropical areas of the central and eastern Pacific Ocean. And this year has scientists worried because excess warming from climate change along with El Niño could result in record heat.

Sea cucumbers (Holothuria scabra) are worm-like creatures that live on the ocean floor and are in the same family as starfish and sea urchins. They range in size from less than an inch to several feet long—and as their name suggests—have a body shape that resembles a cucumber.
