Climate change: The evidence is in

Global July temperatures were the fourth-warmest on record.

Whatever the sceptics and naysayers might say, the evidence - from those who ought to know - that we are faced with climate change caused by we humans.

"Updating their official stance on the relationship between climate change and weather events, the American Meteorological Society (AMS), has now stated plainly that the warming world is a fact beyond reproach and that human activity—despite some natural variability—is the main force behind such changes.

"Warming of the climate system now is unequivocal," the group said in a statement on Monday. "Observations show increases in globally averaged air and ocean temperatures, as well as widespread melting of snow and ice and rising globally averaged sea level."

The dominant cause of the warming since the 1950s is human activities, they said, adding that their scientific finding is based on "a large and persuasive body of research."

"Due to natural variability," the statement noted, "not every year is warmer than the preceding year globally. Nevertheless, all of the 10 warmest years in the global temperature records up to 2011 have occurred since 1997, with 2005 and 2010 being the warmest two years in more than a century of global records."

"This statement is the result of hundreds of hours of work by many AMS members over the past year," comments AMS Executive Director Keith Seitter. "It was a careful and thorough process with many stages of review, and one that included the opportunity for input from any AMS member before the draft was finalized."

Turning to the causes of such drastic changes, the AMS concluded that although the climate is always changing in some respects, the melting of the polar ice sheets, extreme flooding, intense droughts and the retreat of most of the world's glaciers "are beyond what can be explained by the natural variability of the climate."

They continue: "It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide. The most important of these over the long term is CO2, whose concentration in the atmosphere is rising principally as a result of fossil-fuel combustion and deforestation."

Reading the Chilcot Inquiry Report more closely

Most commentary on the Chilcot Inquiry Report of and associated with the Iraq War, has been "lifted" from the Executive Summary.   The Intercept has actually gone and dug into the Report, with these revelations : "THE CHILCOT REPORT, the U.K.’s official inquiry into its participation in the Iraq War, has finally been released after seven years of investigation. Its executive summary certainly makes former Prime Minister Tony Blair, who led the British push for war, look terrible. According to the report, Blair made statements about Iraq’s nonexistent chemical, biological, and nuclear programs based on “what Mr. Blair believed” rather than the intelligence he had been given. The U.K. went to war despite the fact that “diplomatic options had not been exhausted.” Blair was warned by British intelligence that terrorism would “increase in the event of war, reflecting intensified anti-US/anti-Western sentiment in the Muslim world, including among Muslim communities in the

Robert Fisk's predictions for the Middle East in 2013

There is no gain-saying that Robert Fisk, fiercely independent and feisty to boot, is the veteran journalist and author covering the Middle East. Who doesn't he know or hasn't he met over the years in reporting from Beirut - where he lives?  In his latest op-ed piece for The Independent he lays out his predictions for the Middle East for 2013. Read the piece in full, here - well worthwhile - but an extract... "Never make predictions in the Middle East. My crystal ball broke long ago. But predicting the region has an honourable pedigree. “An Arab movement, newly-risen, is looming in the distance,” a French traveller to the Gulf and Baghdad wrote in 1883, “and a race hitherto downtrodden will presently claim its due place in the destinies of Islam.” A year earlier, a British diplomat in Jeddah confided that “it is within my knowledge... that the idea of freedom does at present agitate some minds even in Mecca...” So let’s say this for 2013: the “Arab Awakening” (the t

An unpalatable truth!

Quinoa has for the last years been the "new" food on the block for foodies. Known for its health properties, foodies the world over have taken to it. Many restaurants have added it to their menu. But, as this piece " Can vegans stomach the unpalatable truth about quinoa? " from The Guardian so clearly details, the cost to Bolivians and Peruvians - from where quinoa hails - has been substantial. "Not long ago, quinoa was just an obscure Peruvian grain you could only buy in wholefood shops. We struggled to pronounce it (it's keen-wa, not qui-no-a), yet it was feted by food lovers as a novel addition to the familiar ranks of couscous and rice. Dieticians clucked over quinoa approvingly because it ticked the low-fat box and fitted in with government healthy eating advice to "base your meals on starchy foods". Adventurous eaters liked its slightly bitter taste and the little white curls that formed around the grains. Vegans embraced quinoa as
