Ice Planet Update: Arctic Sea Ice Near Historic Low – Antarctic Ice Continues Decline
Editor’s note: we live on a world that is mostly an ocean world, part Icy world, part desert world etc. Other worlds in our solar system exhibit both similar and […]

Ancient Ocean Slowdown Warns Of Future Climate Chaos On Earth
When it comes to the ocean’s response to global warming, we’re not in entirely uncharted waters. A UC Riverside study shows that episodes of extreme heat in Earth’s past caused […]
