The global warming deniers are at it again, and it is high time that the environmental movement in Canada and the United States launched an organized campaign to expose these scientific community charlatans.

The mainstream business media, which bows to corporate interests in both countries, is quick to publish interviews and opinion articles by the tiny percentage of scientists who deny that global warming exists. Some say that it has not been proven that human activity damages the environment. Some bizarrely claim that emissions of carbon dioxide are beneficial to the planet.

It's been a busy long weekend for Canadian political news. The resignation of Stephen Harper's Chief-of-Staff Nigel Wright, and the growing Senate expense scandal, has even made worldwide headlines. 

BBC News reported: "Canadian Prime Minister Stephen Harper's top aide has resigned over his role in a growing expenses scandal. Nigel Wright quit after revelations he had secretly given a senator a C$90,000 (£58,000; $87,000) cheque to help repay improperly claimed housing expenses. The conservative prime minister said he had accepted the resignation of his chief of staff 'with great regret.'"

It's Election Day in B.C. and the NDP is widely expected to end a dozen years of rule by the BC Liberals. As usual in B.C. elections, major corporate-owned newspapers have come out in favour of the corporate-backed Liberals. But the editorials are less than ringing endorsements and -- in the case of the Globe and Mail -- less than totally accurate. And there's one big editorial endorsement missing. 

The Vancouver Sun editorial board has -- in an unusual move for them -- declined to issue an election editorial endorsement. This can be read as a lack of confidence in Christy Clark and the BC Liberals. 

By 'free speech' some folks mean not 'freedom', or more specifically the ‘freedom to speak to power’, they mean speaking without constraint: saying whatever you want, whenever you want, about whoever you want, wherever you want.

Just when you thought CBC's disrespectful and biased reporting of Venezuela on the occasion of the death on March 5 of President Hugo Chavez couldn’t get worse, it did.

All week on CBC Radio One, the network has been promoting a story on its Saturday morning newsmagazine Day Six arguing that Chavez and the Bolivarian Revolution he led has fraudulently appropriated the political legacy of Simon Bolivar, the legendary leader of the anti-colonial struggle in Latin America of the late 1700s and early 1880s.

The CRTC could make us all pay for American-style right-wing media as part of our cable packages -- unless we stop them.

Quebecor created a "Fox News North" to model the kind of hate-filled propaganda with which Fox News has poisoned U.S. politics. The channel is run by PM Harper's former top aide and so far it doesn't have enough of an audience to survive. But now it's applying to the CRTC to be forcibly added to all of our basic cable packages!

The world's eyes are on London, host of the 2012 Summer Olympics. The hosting rights, won under Tony Blair's government slightly more than 7 years ago, are not viewed as enthusiastically by Londoners anymore. It will be anything short of a miracle for the games to proceed without a hitch.

London's international airport, Heathrow, runs at near full capacity most of the year and will be running over capacity when the athletes and spectators begin arriving from everywhere corner of the globe. And it is guaranteed that the London Underground will also be running over capacity. But these are problems that cannot easily be alleviated. Expansion costs to any public transport system or major aviation hubs cost billions of dollars.

Contrary to the precedent set by Tunisia and Egypt's elections, it appears Libya's Islamist parties will not win a majority in the first post-Gaddafi government.

While much of the world's attention on the region continues to be focused on the escalation of violence in Syria, Libya's election, although still not officially tallied, is an equally important chapter in the Arab Spring. Liberal and non-Islamist parties have often fared poorly until now. The language of the winning National Forces Alliance has suggested that it wants to build as large of a consensus as possible regarding decisions it makes while it leads the interim government and efforts to draft the new constitution.

Hunted down and persecuted for decades by Egypt's various heads of state, the Muslim Brotherhood has achieved a goal it has pursued since its conception. It now controls the office of the Egyptian presidency.
