Key ocean currents warming at accelerated rate

The signs of climate change appear like pieces of a mosaic, a patchwork of scientific data and observation. Most individual signs don’t carry great significance, but here’s one that does – the persistent rise of the temperature of the oceans over the past 100 years. The research comes from an international team (China, Japan, Australia, […]

New Study: Archean oceans cooler, better for origin of life

A key part of the hypothesis for the origin of life on Earth is that it developed in the oceans. The conventional model of the early oceans has stipulated that the waters of the middle Archean eon, roughly 4.0 to 3.5 billion years ago, were too hot for (abundant) life. The model also assumed that […]
