Climate change continues leaving its mark on the world’s oceans. Water levels are rising along with temperatures. Warmer waters supercharge some marine life's reproduction rates, putting other species' very survival at risk. VOA’s Arash Arabasadi takes us under the sea.

Read MoreExtreme climatic events have recently impacted marine ecosystems around the world, including foundation species such as corals and kelps. Here, we describe the rapid climate-driven catastrophic shift in 2014 from a previously robust kelp forest to unproductive large scale urchin barrens in northern California.
