Melting Ice Opens Fight Over Sea Routes for Arctic Debate – Bloomberg

When 16th and 17th century European explorers sailed west in pursuit of a trade route to Asia, their search for a Northwest Passage was foiled by Arctic ice.

Five hundred years later, melting icecaps have set off a global race to control new shipping lanes over the North Pole. Just as the discoveries of Ferdinand Magellan and Vasco de Gama gave seafaring Portugal routes around Cape Horn and the Cape of Good Hope, the opening of the Arctic, with its shortcut from the Atlantic to northeast Asia and its untapped oil reserves, can redraw the geopolitical map and create new power brokers.

Climate scientists struggle to explain warming slowdown | Reuters

Scientists are struggling to explain a slowdown in climate change that has exposed gaps in their understanding and defies a rise in global greenhouse gas emissions.

Often focused on century-long trends, most climate models failed to predict that the temperature rise would slow, starting around 2000. Scientists are now intent on figuring out the causes and determining whether the respite will be brief or a more lasting phenomenon.

So there are modeling problems. As I said a couple of years ago, when you calibrate a model based on data within a certain range, and then go outside of that range, then your model might not work correctly. When I heard scientists confidently explain how good their climate models were, I knew we were in for trouble. Because a real scientist would understand that moving into new territory is always dangerous.

China Demands U.S. Taxpayers Clean Up Its Air – Forbes

Now Beijing wants even more dough.  The Doha conference produced one advance for climate activists by establishing the principle that developed nations have a responsibility for compensating poorer ones for damage due to climate change.  The rich had previously agreed to provide assistance for clean energy and other purposes but had not acknowledged an obligation for fixing the changing climate.

That changed in Doha.  “It is a breakthrough,” said Martin Khor of the South Centre, an organization of 52 developing states, to the BBC.  “The term Loss and Damage is in the text—this is a huge step in principle.  Next comes the fight for cash.”

Global Warming: The Greatest Threat To Arab Economies? | Economy Watch

The World Bank has produced a massive 450 page report on the potentially devastating impact climate change is likely to have on Arab countries. This matters to everyone and not just from the standpoint that we should all empathize with and seek to relief suffering.

The harsher the conditions get, the more restive and radical the populations of Arab states are likely to become, with hugely destabilizing consequences for all of us.

Climate change seen as factor in Mayan collapse in Central America – UPI.com

Unusually high rainfall allowed a population boom between 440 and 660 A.D., but subsequent dry conditions between 660 and 1000 A.D. aligns with known periods of political instability in the Mayan civilization, Kennett theorizes.

The dry climate conditions, which may have included extended periods of drought, may have hastened the Maya collapse, the researchers say.

Climate Change Threat To National Security – Science News – redOrbit

Food shortages, natural disasters, energy supply issues and the spread of epidemics are some of the possible climate-related perils the U.S. military needs to prepare to deal with, the National Academies claim in a new report released Friday.

Broder says the report warns of “clusters of apparently unrelated events exacerbated by a warming climate will create more frequent but unpredictable crises in water supplies, food markets, energy supply chains and public health systems… Climate-driven crises could lead to internal instability or international conflict and might force the United States to provide humanitarian assistance or, in some cases, military force to protect vital energy, economic or other interests.”

Why 2013 will be a year of crisis – CNN.com

Prediction: 2013 will be a year of serious global crisis. That crisis is predictable, and in fact has already begun. It will inescapably confront the next president of the United States. Yet this emerging crisis got not a mention at the Republican National Convention in Tampa. We’ll see if the Democrats do better.

The crisis originates in this summer’s extreme weather. Almost 80% of the continental United States experienced drought conditions. Russia and Australia experienced drought as well.

Will 2013 bring us social turmoil in Brazil, strikes in China or revolution in Pakistan? The answer can probably be read in the price indexes of the commodities exchanges — and it is anything but reassuring.

Food riots predicted over US crop failure – Features – Al Jazeera English

The world is on the brink of a food “catastrophe” caused by the worst US drought in 50 years, and misguided government biofuel policy will exacerbate the perilous situation, scientists and activists warn.

When food prices spike and people go hungry, violence soon follows, they say. Riots caused by food shortages – similar to those of 2007-08 in countries like Bangladesh, Haiti, the Philippines and Burkina Faso among others – may be on the horizon, threatening social stability in impoverished nations that rely on US corn imports.

This summer’s devastating drought has scorched much of the mid-western United States – the world’s bread basket.

Crops such as corn, wheat, and soy have been decimated by high temperatures and little rain. Grain prices have skyrocketed and concerns abound the resulting higher food prices will hit the world’s poor the hardest – sparking violent demonstrations.

Early dryness in Russia’s wheat growing season, light monsoon rains in India, and drought in Africa’s Sahel region, combined with America’s lost crop, mean a perfect storm is on the horizon.

BBC News – Antarctic may host methane stores

Large volumes of methane – a potent greenhouse gas – could be locked beneath the ice-covered regions of Antarctica, according to a new study.

It says this methane could be released into the atmosphere as ice retreats, contributing to climate warming.

The findings indicate that ancient deposits of organic matter may have been converted to methane by microbes under the ice.

BBC News – Antarctica warmth ‘unusual, but not unique’

The recent Antarctic Peninsula temperature rise and associated ice loss is unusual but not unprecedented, according to research.

Analysis of a 364m-long ice core containing several millennia of climate history shows the region previously basked in temperatures slightly higher than today.

However, the peninsula is now warming rapidly, threatening previously stable areas of ice, the study warns.

The work is reported in Nature journal.

Climate change and the Syrian uprising | Bulletin of the Atomic Scientists

  • A drought unparalleled in recent Syrian history lasted from 2006 to 2010 and led to an unprecedented mass migration of 1.5 million people from farms to urban centers.
  • Because the Assad regime’s economic policies had largely ignored water issues and sustainable agriculture, the drought destroyed many farming communities and placed great strain on urban populations.
  • Although not the leading cause of the Syrian rebellion, the drought-induced migration from farm to city clearly contributed to the uprising and serves as a warning of the potential impact of climate change on political stability.
