BBC | Arctic methane 'time bomb' could have huge economic costs

Scientists say that the release of large amounts of methane from thawing permafrost in the Arctic could have huge economic impacts for the world.

… Previous work has shown that the diminishing ice cover in the East Siberian sea is allowing the waters to warm and the methane to leach out. Scientists have found plumes of the gas up to a kilometre in diameter rising from these waters. In this study, the researchers have attempted to put an economic price on the climate damage that these emissions of methane could cause. Methane is a powerful greenhouse gas, even though it lasts less than a decade in the atmosphere…

They worked out that this would increase climate impacts such as flooding, sea level rise, damage to agriculture and human health to the tune of $60 trillion…

It is thought that up to 30% of the world's undiscovered gas and 13% of undiscovered oil lie in the [Arctic] waters. Transport companies are looking to send increasing numbers of ships through these fast melting seas. According to Lloyds of London, investment in the Arctic could reach $100bn within ten years. But according to the new work, these benefits would be a fraction of the likely costs of a large scale methane emission. The authors say a release of methane on this scale could bring forward the date when global temperatures increase by 2C by between 15 and 35 years.

"We are looking at a big effect," said Prof Peter Wadhams from the University of Cambridge, "a possibly catastrophic effect on global climate that's a consequence of this extremely fast sea ice retreat that's been happening in recent years…"

that's why it's called climate change

That is called seasonal change. Get your terminology straight.

Yep, its going to be a real cold winter.

curious graph. the 2012 line goes lowest in summer, but is higher in winter. looks like 2013 will be back up again both summer and winter (but too early to tell). 2011 was highest in summer, but lowest in winter.

so what exactly does this tell us?

Revelation 11:18

NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION (NOAA) | Arctic nearly free of summer sea ice during first half of 21st century

For scientists studying summer sea ice in the Arctic, it’s not a question of “if” there will be nearly ice-free summers, but “when.” And two scientists say that “when” is sooner than many thought — before 2050 and possibly within the next decade or two…

“Rapid Arctic sea ice loss is probably the most visible indicator of global climate change; it leads to shifts in ecosystems and economic access, and potentially impacts weather throughout the northern hemisphere,” said Overland. “Increased physical understanding of rapid Arctic climate shifts and improved models are needed that give a more detailed picture and timing of what to expect so we can better prepare and adapt to such changes. Early loss of Arctic sea ice gives immediacy to the issue of climate change.”

“There is no one perfect way to predict summer sea ice loss in the Arctic,” said Wang. “So we looked at three approaches that result in widely different dates, but all three suggest nearly sea ice-free summers in the Arctic before the middle of this century.”

Overland and Wang emphasized that the term “nearly” ice free is important as some sea ice is expected to remain north of the Canadian Archipelago and Greenland.

The “trendsetters” approach uses observed sea ice trends. These data show that the total amount of sea ice decreased rapidly over the previous decade. Using those trends, this approach extrapolates to a nearly sea ice-free Arctic by 2020.

The “stochasters” approach is based on assuming future multiple, but random in time, large sea ice loss events such as those that occurred in 2007 and 2012. This method estimates it would take several more events to reach a nearly sea ice-free state in the summer. Using the likelihood of such events, this approach suggests a nearly sea ice-free Arctic by about 2030 but with large uncertainty in timing.

The “modelers” approach is based on using the large collection of global climate model results to predict atmosphere, ocean, land, and sea ice conditions over time. These models show the earliest possible loss of sea ice to be around 2040 as greenhouse gas concentrations increase and the Arctic warms. But the median timing of sea ice loss in these models is closer to 2060. There are several reasons to consider that this median timing of sea ice loss in these models may be too slow.

Scientists hope volcanic rock can contain climate change | THE VERGE

Capturing and storing greenhouse gases beneath the earth could allow climate change to be mitigated, but researchers still need to find a method that can both permanently and safely contain the gases. Now researchers at the Pacific Northwest National Laboratory (PNNL) believe that they may have found an option: they've begun injecting carbon dioxide (CO2) — one of the main gases involved in global warming — a half-mile underground into flows of basalt, a volcanic rock, to see if it will stay put. PNNL's researchers suggest that because basalt is porous, it'll be able to hold onto CO2 when it's inserted in a liquid form. According to Nature, the basalt should also initiate a chemical reaction that will ultimately turn the mixture into limestone — though the process will take decades...

Seafarers Can Help Track Effects of Climate Change | BLUE WATER SAILING / CRUISING COMPASS

Seafarers are being encouraged to take part in a unique global study, using a mobile phone app to record the effects of climate change.

The marine phytoplankton account for approximately 50% of all photosynthesis on Earth and, through the plankton food web that they support, they both underpin the marine food chain and play a central role in the global carbon cycle strongly influencing the Earth’s climate. Living at the surface of the sea the phytoplankton are particularly sensitive to changes in sea surface temperature. A recent study of global phytoplankton abundance over the last century concluded that global phytoplankton concentrations have declined due to rising sea surface temperatures as a consequence of current climate change.

No one disputes climate change. The disputation is over the cause of it. Earth is now cooling in the cyclical fashion that has been shown to exist.

curious how the warmer places is also the least populated parts of the earth. According to the color density, the Antarctic south of the cape, and the Canadian Arctic is the warmest, even more than the equator!

I never cease to be amazed how folks who typically show above-average intelligence can't read the provided legend. What's being displayed is the Temperature Difference, not the absolute temperature. But you did notice correctly that the polar regions are heating up faster than the temperate and tropical regions. That's why the rapid melting of the Arctic Ocean sea ice is a big deal. It's the canary in the coal mine, a warning of what's headed our way.
