Dahr Jamail | Record Heating of Earth’s Oceans Is Driving Uptick in Hurricanes http://www.truth-out.org/news/item/37877-record-heating-of-earth-s-oceans-is-driving-uptick-in-hurricanes Thursday, 06 October 2016 By Dahr Jamail, Truthout | Report As Hurricane Matthew impacts the East Coast of the US this week, it is important to consider how rising ocean temperatures are contributing to the intensification of storms worldwide. Earlier this year, a scientific study titled […]
You might have a replacement, Pluto. There could be another planet in our solar system.
Researchers at the California Institute of Technology have found evidence in the outer solar system of an object that could be a real ninth planet.
Nicknamed Planet Nine, it “has a mass about 10 times that of Earth and orbits about 20 times farther from the sun” than Neptune. That means “it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun,” according to Caltech.
Researchers Konstantin Batygin and Mike Brown haven’t actually seen the planet, but other research helped lead them to conclude that there is one. Basically, they found that certain objects in the Kuiper Belt — the field of icy objects and debris beyond Neptune — had orbits that peculiarly pointed in the same direction.
Over time, mathematical modeling and computer simulation led them to the conclusion that a planet was exerting the gravity necessary to shape these orbits.
Brown says “there have only been two true planets discovered since ancient times, and this would be a third. It’s a pretty substantial chunk of our solar system that’s still out there to be found, which is pretty exciting.”
Already, Caltech is pretty confident Planet Nine is large enough to rule out any debate about whether it’s a true planet — unlike Pluto, which got the boot in 2006
The projected upsurge of severe El Niño and La Niña events will cause an increase in storm events leading to extreme coastal flooding and erosion in populated regions across the Pacific Ocean, according to a multi-agency study published Monday in Nature Geoscience.
The impact of these storms is not presently included in most studies on future coastal vulnerability, which look primarily at sea level rise. New research data, from 48 beaches across three continents — including Hawaii — and five countries bordering the Pacific Ocean, suggest the predicted increase will exacerbate coastal erosion irrespective of sea level rise affecting the region.
Researchers from 13 different institutions analyzed coastal data from across the Pacific Ocean basin from 1979 to 2012. The scientists sought to determine if patterns in coastal change could be connected to major climate cycles.
Although previous studies have analyzed coastal impacts at local and regional levels, this is the first to pull together data from across the Pacific to determine basin-wide patterns. The research group determined all Pacific Ocean regions investigated were affected during either an El Niño or La Niña year.
When the west coast of the U.S. mainland and Canada, Hawaii, and northern Japan felt the coastal impacts of El Niño, characterized by bigger waves, different wave direction, higher water levels and/or erosion, the opposite region in the Southern Hemisphere of New Zealand and Australia experienced “suppression,” such as smaller waves and less erosion.
The pattern then generally flips: during La Niña, the Southern Hemisphere experienced more severe conditions.
The published paper, “Coastal vulnerability across the Pacific dominated by El Niño/Southern Oscillation” is available online.
Abstract: To predict future coastal hazards, it is important to quantify any links between climate drivers and spatial patterns of coastal change. However, most studies of future coastal vulnerability do not account for the dynamic components of coastal water levels during storms, notably wave-driven processes, storm surges and seasonal water level anomalies, although these components can add metres to water levels during extreme events. Here we synthesize multi-decadal, co-located data assimilated between 1979 and 2012 that describe wave climate, local water levels and coastal change for 48 beaches throughout the Pacific Ocean basin. We find that observed coastal erosion across the Pacific varies most closely with El Niño/Southern Oscillation, with a smaller influence from the Southern Annular Mode and the Pacific North American pattern. In the northern and southern Pacific Ocean, regional wave and water level anomalies are significantly correlated to a suite of climate indices, particularly during boreal winter; conditions in the northeast Pacific Ocean are often opposite to those in the western and southern Pacific. We conclude that, if projections for an increasing frequency of extreme El Niño and La Niña events over the twenty-first century are confirmed, then populated regions on opposite sides of the Pacific Ocean basin could be alternately exposed to extreme coastal erosion and flooding, independent of sea-level rise.

WATCH: A San Jose area man has released video of a mountain lion that climbed on his car and stalked across his lawn before disappearing into the neighbourhood. Betty Yu reports.
TORONTO – A San Jose area man has released surveillance video of a mountain lion that climbed on his car early Tuesday morning in an effort to warn neighbours.
“It was scary… I did not expect [it in] this area because this is still [the] city,” homeowner David Tang told CBS reporter Betty Yu.
The cat pounced on the roof of Tang’s Toyota Camry – parked in the driveway – around 3 a.m.
He says he released the video to warn his Almaden Valley neighbours of the dangers lurking nearby.
“The major concern I have is the safety for the kids, and lots of single people doing a morning walk,” Tang told KPIX.
