Hello Australia! - Is Bitcoin's founder an Aussie? - The environmentalist founder of the North Face is dead - Greenpeace unmasks climate change deniers for hire - And more in your CareerSpot World News Briefs:

Australian Federal Police raided the Gordon, NSW home of one Craig Steven Wright - identified by leading tech publications a few hours earlier as the possible real identity of "Satoshi Nakamoto", inventor of the Bitcoin.  More than ten officers swooped in on the home in what is described as an Australian Tax Office investigation.  The identity of Satoshi Nakamoto has been a mystery that has vexed tech journalists, and at least three other people have been fingered as the crypto-currency founder - but there's no confirmation of the claims made by Gizmodo and Wired Magazine, and there are some who believe that Satoshi Nakamoto may be a group of people, not just one person.  Nakamoto is believed to own a million Bitcoins worth half a billion dollars, all off the official books of the world's tax authorities.

The founder of The North Face outdoor clothing store and noted environmentalist Douglas Tompkins is dead at age 72.  He was kayaking on General Carrera Lake in Patagonia in southern Chile with a group of five others when his boat flipped, possibly because of a wave, and he fell into the icy waters.  Wen they pulled him out of the water, is body temperature was just 19 degrees C, and he was pronounced dead of hypothermia in hospital hours later.  Tompkins will be remembered not just for the clothes, but for buying up tracts of land in Patagonia in Chile and Argentina and converting them into protected nature preserves.

An undercover sting by Greenpeace reveals that two leading voices of global warming denial have been outed deniers-for-hire.  The Greenpeace investigators posed as executives with a coal company and an oil company.  Professor William Happer of Princeton University and retired University of Pennsylvania sociologist Frank Clemente each discussed writing papers to cast doubt on climate change and how to hide the funding from the fake energy companies.  Both men hold opinions outside the mainstream of climate science, but are cited by conservatives when denying the obvious.  Peter Frumhoff of the Union of Concerned Scientists said the sting was "deeply, deeply disconcerting".

Decades of "reckless arms trading" and lax controls have enabled the atrocities committed by Islamic State.  A new report from Amnesty International says most of IS's armory comes from stockpiles captured from the US-allied Iraqi military and Syrian rebels, but it's even deeper than that.  "It goes back to the days of the Iran-Iraq war.  It certainly includes what happened during the invasion and occupation of Iraq by US-led forces and it continues now.  And so many of those weapons have found their way into the hands of Islamic State forces and are now being used for these horrific crimes" says Amnesty's Alex Neve.

The number of foreign fighters joining Islamic state in Syria has more than doubled since June 2014.  The report from the security consultancy the Soufan Group (.pdf link) notes that the number of foreign fighters went from 12,000 to at least 27,000.  Most came from Tunisia, followed by Saudi Arabia and Russia.  The authors says the West needs to come up with a counter to the appeal of joining IS.  That actually happened organically over the weekend, with the social media hashtag #YouAintNoMuslimBruv that arose as a reaction to a terrorist stabbing incident in London's Leytenstone tube station.  That hashtag "does far more to undermine Isis than dropping bombs on Raqqa", according to Richard Barrett, a former MI6 agent who contributed to the Soufan Group report.

Outgoing Argentine President Cristina Fernandez de Kirchner (CFK) will not attend the swearing in of her successor on Thursday.  This follows bickering between the two camps over where the ceremony will be held.  CFK wants to hand over the Presidential Baton and Sash in Congress, where Mauricio Macri will take his oath of office.  But Macri wants the presentation to take place in the presidential palace Casa Rosada ("Pink House").

Venezuela's National Electoral Council published the final tally of the weekend election, confirming that the conservative opposition has won a super-majority in congress.  This gives them the power to not only reverse the policies of the late Hugo Chavez and his successor President Nicolas Maduro - but also the ability to remove Maduro from office before his term ends in 2019 by rewriting the constitution.  Visiting Chavez' grave on Tuesday, Maduro vowed to hang on:  "The bad guys won, like the bad guys always do, through lies and fraud," he said.  "Workers of the fatherland know that you have a president, a son of Chavez, who will protect you."
