If you haven't guessed, I like the subject of ice.

Warm Ocean Rapidly Melting Antarctic Ice Shelf from Below

In a paper published in the journal Science on Sept. 13, the team describes how at one of their study sites, halfway down the ice shelf, the melt rate was as high as 2.36 inches (6 centimeters) per day.

A century of human impact on Arctic climate indicated by new models and historic aerosol data contained in ice cores

The authors attribute warming from 1900-1939 to rapidly rising black carbon emissions, diminishing influence of the Santa Maria volcanic eruption in 1902, and warming North Atlantic sea surface temperatures. Cooling from 1939 to 1970 is attributed to cooling from anthropogenic sulfate aerosol emissions the Agung volcanic eruption in 1963, and falling North Atlantic surface temperatures.
More recently, the authors attribute warming from 1970 to present to increased anthropogenic greenhouse gas emissions, with a smaller contribution from warming North Atlantic sea surface temperatures.

Access to the study is free.

Unprecedented Rate and Scale of Ocean Acidification Found in the Arctic

The new research shows that acidification in surface waters of the Arctic Ocean is rapidly expanding into areas that were previously isolated from contact with the atmosphere due to the former widespread ice cover.

"A remarkable 20 percent of the Canadian Basin has become more corrosive to carbonate minerals in an unprecedented short period of time. Nowhere on Earth have we documented such large scale, rapid ocean acidification" according to lead researcher and ocean acidification project chief, U.S. Geological Survey oceanographer Lisa Robbins.

Well this is only indirectly related to climate change as is intended here, but it could help to spell a greener future.

One day, we may fill the tank with fungi fuel!

Or perhaps keep us all fed. After all the projections are that we will hit 9 billion souls by 2045.

Global Warming to Spawn More Severe U.S. Thunderstorms: Study

Why Is It Important?


The simulations all agreed that continued global warming will lead to increases in storm days over large areas of the eastern United States in the spring, winter, and autumn.


The changes mean that for springtime alone, severe thunderstorms could increase by as much as 40 percent over the eastern U.S. by the end of the century, Diffenbaugh said.


What Does This Mean?


Severe thunderstorms, which are often associated with heavy rainfall, hail, and even tornadoes, are one of the primary causes of major economic losses in the United States.


In 2012, seven of the country's $11 billion weather disasters were caused by severe thunderstorms and tornadoes.


"Sadly, we have many examples of cases where a single storm has had disastrous impact," Diffenbaugh said in a statement. "So a 25 or 30 percent increase in the annual occurrence represents a substantial increase in the overall risk."

If that's the case, I doubt the population will hit those projections. The U.S. and Canada feed a lot of the worlds population and severe weather would certainly impact crops, especially from hail damage. Ya think?

Unfortunately; "only the shadow knows".

IPCC climate report: Global warming now 'unequivocal'

On the ground, in the air, in the oceans, global warming is "unequivocal", according to a landmark report on the Earth's climate.

The report by the UN's climate panel details the physical evidence behind climate change.

Scientists are 95% certain that humans have been the "dominant cause" of the rise in temperatures since the 1950s.

I'm glad I'm not a scientist. I've been under the assumption that anthropogenic global warming is a 100% certainty.

What's that phrase? Oh yes; "Prepare for the worst......."

Mystery 13th Century eruption traced to Lombok, Indonesia

Scientists think they have found the volcano responsible for a huge eruption that occurred in the 13th Century.

The mystery event in 1257 was so large its chemical signature is recorded in the ice of both the Arctic and the Antarctic.

European medieval texts talk of a sudden cooling of the climate, and of failed harvests.

In the PNAS journal, an international team points the finger at the Samalas Volcano on Lombok Island, Indonesia.

Little remains of the original mountain structure - just a huge crater lake.

OECD: 'No bailout' for climate threat

Governments forced to rescue the world's banking system are being warned there will be no bailout if there is a crisis in the Earth's climate system.

That is the view of the head of the Organisation for Economic Co-operation and Development (OECD).

.....

Mr Gurria is due to address the topic of climate change, investment and energy policies in a London lecture co-organised with the London School of Economics and the Climate Markets & Investors Association (CMIA)

The talk coincides with a report in The Independent newspaper that claims UK Chancellor George Osborne is about to reject the recommendations of government advisers by slowing the drive to tackle global warming.

Global warming will increase intensity of El Nino, scientists say

Good if it's true.

Greenhouse Gases Have Soared to Record Levels: WMO

Average temperature in Northern Hemisphere may have hit highest between 1990-2010

Global warming: Australian scientists find explanation for pause in rising temperatures

Scientists have come up with an explanation for the pause in global warming, which has long been a point of contention raised by climate change sceptics.

Over the past 15 years the rate of global warming has slowed - and more recently almost stalled.

Professor England led a team of researchers from around the world that has come up with an explanation for why the oceans soak up the heat.

Their research, published in the journal Nature Climate Change, has found the answer lies in stronger than usual trade winds whipping across the Pacific Ocean.

It was found the winds were churning the Pacific like a washing machine, bringing the deeper colder water to the surface and pushing the warmer water below.

"The phase we're in of accelerated trade winds particularly lasts a couple of decades," Professor England said.

"We're about 12 to 13 years in to the most accelerated part of the wind field.

"It's important to point out there's a cycle we expect to reverse and when they do reverse back to their normal levels we'd expect global warming to kick in and start to rise."
