Where the Columbia River meets the Pacific Ocean

An evening pause: But not very relaxing. Hat tip to Phill Oltmann, who notes “This video is of commercial fishing boats returning from fishing off the coast of Washington and Oregon. They are crossing the Columbia Bar, which is the site the Columbia River meets the Pacific Ocean.”

Coral islands defy sea level rise

The uncertainty of science: Despite having some of the highest rates of sea level rise in the past century, the 29 islands of Funafuti Atoll in the Pacific show no signs of sinking.

Despite the magnitude of this rise, no islands have been lost, the majority have enlarged, and there has been a 7.3% increase in net island area over the past century (A.D. 1897–2013). There is no evidence of heightened erosion over the past half-century as sea-level rise accelerated. Reef islands in Funafuti continually adjust their size, shape, and position in response to variations in boundary conditions, including storms, sediment supply, as well as sea level.

Be aware as well that the cause of the rise in sea level here is not clearly understood. It could be the global warming we have seen since the end of the Little Ice Age of the 1600s, or other more complex factors.

El Niño has finally arrived, far weaker than predicted

The uncertainty of science: The periodic warm weather pattern called El Niño has finally arrived in the mid-equatorial Pacific Ocean, more than a year late and far weaker than predicted by scientists.

The announcement comes a year after forecasters first predicted that a major El Niño could be in the works. At the time, NOAA predicted a 50% chance that an El Niño could develop in the latter half of 2014. The agency also said the wind patterns that were driving water east across the Pacific were similar to those that occurred in the months leading up to the epic El Niño of 1997, which caught scientists by surprise and contributed to flooding, droughts and fires across multiple continents.

In the end, last year’s forecasts came up short, in part because the winds that were driving the system petered out. Researchers, who have been working to improve their forecasting models since 1997, are trying to figure out precisely what happened last year and why their models failed to capture it.

But remember, these same climate scientists are absolutely sure that their climate models can predict the temperature rise of the climate to within a degree one century hence. Yet, they have no idea why this El Niño turned out weak and late, even though it exhibited the same early features as the epic 1997 El Niño.

The CIA has now declassified the story behind their effort in 1971 and 1972 to recover a satellite film canister from 16,400 feet below sea level in the Pacific.

Humans do it quickly

Marshall Islands

A team of scientists from Japan have found evidence that the human settlement of the Marshall Islands in the central Pacific Ocean occurred almost immediately after those islands emerged from beneath the sea. Though it had been previously believed that a thousand years had to pass until these newly emerged islands had developed sufficient vegetation for humans to occupy them, the evidence from this study shows that humans not only showed up almost immediately, they acted to vegetate the island themselves in order to make it habitable.

The scientists drilled four cores just off the western shore of Laura Island, the largest island of Majuro Atoll, as well as thirteen trenches on that same island, in order to determine when the island first emerged from under the sea. They also excavated a well-preserved bank at the center of Laura Island to study the human occupation of the island.

What they found was that the Atoll emerged from underwater approximately 2000 years ago, triggered by a fall in sea level. More surprising, the first evidence of human settlement appeared to occur at almost the same time.
