Submission + - Reuters- Arctic ice loss driven by natural swings, not just mankind: study (reuters.com)

bricko writes: Arctic ice loss driven by natural swings, not just mankind: study -
Natural swings in the Arctic climate have caused up to half the precipitous losses of sea ice around the North Pole in recent decades, with the rest driven by man-made global warming, scientists said on Monday.

The study indicates that an ice-free Arctic Ocean, often feared to be just years away, in one of the starkest signs of man-made global warming, could be delayed if nature swings back to a cooler mode.

Natural variations in the Arctic climate "may be responsible for about 30–50 percent of the overall decline in September sea ice since 1979," the U.S.-based team of scientists wrote in the journal Nature Climate Change.

bricko writes: Climatologists say Labrador Sea could cool within a decade before end of this century, leading to unprecedented disruption.
Climatologists who have looked again at the possibility of major climate change in and around the Atlantic Ocean, a persistent puzzle to researchers, now say there is an almost 50% chance that a key area of the North Atlantic could cool suddenly and rapidly, within the space of a decade, before the end of this century.

Submission + - Climate variation proof involves chaotic planetary movements (wisc.edu)

bricko writes: The finding, published Feb. 23, 2017 in the journal Nature, is important because it provides the first hard proof for what scientists call the “chaotic solar system,” a theory proposed in 1989 to account for small variations in the present conditions of the solar system. The variations, playing out over many millions of years, produce big changes in our planet’s climate — changes that can be reflected in the rocks that record Earth’s history.

The discovery promises not only a better understanding of the mechanics of the solar system, but also a more precise measuring stick for geologic time. Moreover, it offers a better understanding of the link between orbital variations and climate change over geologic time scales.

Submission + - Greenland Enters 2017 Adding Massive amount of Ice (beta.dmi.dk)

bricko writes: Greenland Enters 2017 Adding Massive amount of Ice

DMI reports the Greenland ice sheet’s “mass surface budget” has been growing significantly since October.

Greenland’s “surface mass budget” for winter 2016-2017 is already more than two standard deviations higher than the northern ice sheet’s mean snow and ice accumulation over the last 24 years. DMI data shows the ice sheet added 8 gigatons of ice and snow Jan. 1, well above the standard deviation for that day.

Logbooks from the likes of Captain Robert Scott and Sir Ernest Shackleton — key figures in the 'Heroic Age' of Antarctic exploration — have revealed that sea ice levels in Antarctica have barely changed over the past century, despite global temperatures hitting record highs year after year.

Submission + - Elon Musk under investigation for Solar Subsidies (dailysignal.com)

bricko writes: The Senate Finance Committee and the House Ways and Means Committee have launched a probe into tax incentives paid to solar companies, according to The Wall Street Journal.

Already grossly subsidized, Musk’s SolarCity has become an albatross of waste, fraud, and abuse of tax payer dollars. As legitimate earnings and cash become even scarcer for SolarCity, its entanglement in the Tesla empire suggests that a drastic reckoning not only is imminent, but in fact emboldening Musk to become more outlandish and reckless.

Notably, SolarCity is run by Musk’s cousins, Lyndon and Peter Rive. During his chairmanship at SolarCity, Musk’s family enterprise has taken in billions of taxpayer dollars in subsidies from both the federal and local governments. But the subsidies and sweetheart deals were not enough, as losses and missed projections continued to mount.

Submission + - Did Processor Cause Samsung Note 7 Blowup? (eetimes.com)

bricko writes: New report emerged Wednesday that the culprit might not be the lithium-ion batteries themselves, which Samsung initially suspected. Rather, the problem might reside in the underlying technology — tweaks made to the processor in the smartphone.

Attributing an unnamed source who has spoken to Samsung chiefs, the Financial Times reported, “Problems with the phone appeared to have arisen from tweaks to the processor to speed up the rate at which the phone could be charged.”

trying to hide what really happened in any kind of car accident could soon become just about impossible.

That’s the lesson of an incident over the weekend in which the owner of a Tesla Model X SUV crashed into a building and claimed it had suddenly accelerated on its own. But Tesla vehicles are constantly connected to their manufacturer via the Internet and was found not to be so.

Submission + - IBM layofffs hide shuffling jobs/employees to low paid areas of world (ieee.org)

bricko writes: Why are journalists and tech workers paying so much attention to the IBM layoffs? One reason is the strong suspicion that IBM’s secrecy about the cuts—the company is making numbers public only when local laws require, and has refused to break down its head count regionally—is designed to cover some less than admirable behavior.

Perhaps, it’s been suggested, the whole “rebalancing” effort actually means pushing jobs to low-cost regions. Writes Steve Pitcher in MC Press Online: “Leaked documents show IBM India now has more workers than IBM in the U.S. Why? Take a guess. The average IBM India employee is paid $17,000 per year.”

Or, perhaps the effort is designed to remove older, more expensive workers: Journalist and IBM watcher Robert X. Cringely is trying to determine whether IBM has violated age discrimination laws with this year’s layoffs. He’s trying to gather evidence, and suggests that soon-to-be-former employees over 40 force an investigation by the Equal Employment Opportunity Commission (EEOC), by filing a charge of age discrimination against the company.
