These posts include a brief mention of a number of news items relating to climate change. They don’t preclude treating any of these topics at more length in a separate post.
They can also serve as an open thread so that we can keep each other informed on important climate news.
November turns out to be the hottest on record
I thought that with a La Nina, November temperatures would turn out to be cooler than 2005 on the NASA GISS record. Turns out they were the hottest on record. Here are some images from the post:

The birds-eye view for November from the North Pole:
GISS are expecting the full-year result to be the same as 2005 within the margin of error.
Deep ocean heat melts Antarctic ice
Metaphorically below the radar, actually below the sea surface deep ocean heat is melting Antarctic ice.
“In the area I work there is the highest increase in temperatures of anywhere on Earth,” said physical oceanographer Doug Martinson of the Lamont-Doherty Earth Observatory.
That’s at at Palmer Island, on the western side of the Antarctic Peninsula.
But his jaw really dropped when he saw data from the past and deep ocean heat content measurements worldwide. All show the same rising trend that is being seen in Antarctica. That’s where more than 90% of the heat has been going since 1960. Now it’s chewing away at the bottom of the ice in Antarctica.
A new paper by O’Donnell, Lewis, McIntyre and Condon on temperature trends in Antarctica is scaring the carrots out of Eli at Rabbett Run.
One to watch.
Greenland ice loss accelerates
Greenland ice loss has been spectacular in recent years. Skeptical Science explains how it happens.
The hockey stick again
Future historians — and countless long-suffering future generations — will be quite puzzled that during the same short window humanity was given to avert multiple catastrophes predicted by basic science, a vast amount of effort went into a debate over the so-called “Hockey Stick” graph developed by leading U.S. climatologists and substantiated by multiple independent analyses.
They reckon in a few decades time we’ll be talking about right angles,
Joe Romm gives his usual comprehensive treatment, with plenty of graphs.
Canadian oil sands interests attempting to block US carbon regulations
Yes, millions is being spent by Alberta oil sands interests and American oil refining companies on such an attempt, supported by the Canadian Government.
That’s because they have spent many billions investing in the production and supply of petrol from the tacky ooze, 82% more carbon intensive than light Texan crude. The Alberta operation is set to triple by 2025.
Initially they worried about regulations proposed in California to introduce a low carbon fuel standard (LCFS), which fortunately survived Proposition 23 designed to knock them out in the recent elections. Now similar regulations are being considered or adopted in 24 states. This would create pressure for national regulations. Time for ruthless capitalists to panic and swing into action.
Raw commercial self-interest.
South-east Asia will be hardest hit by climate change
That’s the headline. The text tells us that China will be the biggest loser, because of reduced river flows.
But widespread effects will be evident by 2030.
Good the the spooks are keeping an eye on climate change and good that WikiLeaks let us know.
Melting glaciers threaten floods in Himalayas, Andes
Speaking of floods and trickles in glacier-fed rivers, at Cancun the folks were being worded up about melting glaciers in the Himalayas and Andes.
Residents of the Himalayas and other mountain areas face a “tough and unpredictable future” as global warming melts glaciers and threatens worse floods and water loss, officials said during U.N. climate talks on Tuesday.
A study said that glaciers in southern Chile and Argentina, followed by ones in Alaska, had been losing mass “faster and for longer than glaciers in other parts of the world.”
But it’s not just a future issue. Problems are being experienced now and people living in those areas need more help.
Salty irrigation water in Vietnam
Salty irrigation water has been found 20 km from the sea in the Mekong Delta.
A third of the Mekong Delta could be submerged if the sea rose by 1 meter. Twenty per cent of Vietnam’s 86 million people live there, growing half the country’s rice in one of earth’s most biodiverse regions. Vietnam is the world’s second biggest rice exporter.
Closer to home
Closer to home Sydney has lots to worry about according to new sea level and storm surge threat maps.
Seems we should all plant bamboo. Seriously!
