The Ocean Is Starting to Lose Its Memory, Scientists Warn

The oceans that surround us are transforming. As our climate changes, the world’s waters are shifting too, with abnormalities evident not only in the ocean’s temperature, but also its structure, currents, and even its color. As these changes manifest, the usually stable environment of the ocean is becoming more unpredictable and erratic, and in some …
