Arctic sea ice melting faster than expected —WMO

A major source of the water for the sea level rise already affecting Savannah and Jacksonville is melting Arctic Ocean sea ice. WMO Press Release No. 966: 2012: Record Arctic Sea Ice Melt, Multiple Extremes and High Temperatures,

“Naturally occurring climate variability due to phenomena such as El Niño and La Niña impact on temperatures and precipitation on a seasonal to annual scale. But they do not alter the underlying long-term trend of rising temperatures due to climate change as a result of human activities,” said WMO Secretary-General Michel Jarraud.

“The extent of Arctic sea ice reached a new record low. The alarming rate of its melt this year highlighted the far-reaching changes taking place on Earth’s oceans and biosphere. Climate change is taking place before our eyes and will continue to do so as a result of the concentrations of greenhouse gases in the atmosphere, which have risen constantly and again reached new records,” added Mr Jarraud.

30 years of Arctic sea ice 15 September 1982 vs 16 September 2012

The Arctic reached its lowest annual sea ice extent since the start of satellite records on 16 September at 3.41 million square kilometers. This was 18% less than the previous record low of 18 September, 2007. The 2012 minimum extent was 49 percent or nearly 3.3 million square kilometers (nearly the size of India) below the 1979—2000 average minimum. Some 11.83 million square kilometers of Arctic ice melted between March and September 2012.

WMO noted other effects of climate change outside the arctic, including:

Savannah and Jacksonville most vulnerable to rising sea level

Savannah and Jacksonville are among the east coast cities most vulnerable to rising sea levels due to climate change, a study finds. Savannah, Georgia’s main seaport, with storm surges, hurricanes, and waves on top: what will that look like?

Suzanne Goldenberg wrote for the Guardian today, US coastal cities in danger as sea levels rise faster than expected, study warns: Satellite measurements show flooding from storms like Sandy will put low-lying population centres at risk sooner than projected,

A study published last March by Climate Central found sea-level rise due to global warming had already doubled the risk of extreme flood events — so-called once in a century floods — for dozens of locations up and down the Atlantic and Pacific coasts.

It singled out the California cities of Los Angeles and San Diego on the Pacific coast and Jacksonville, Florida, and Savannah, Georgia, on the Atlantic, as the most vulnerable to historic flooding due to sea-level rise.

Sandy, which produced a 9ft storm surge at Battery Park in New York City, produced one example of the dangerous combination of storm surges and rising sea level. In New York, each additional foot of water puts up to 100,000 additional people at risk, according to a map published with the study.

That study projected 6 inches rise at Fort Pulaski by 2030 (minimum 3 inches) and 13 inches by 2050 (maximum 24 inches). But projections have gotten worse since then:

Sea level changes measured and projected The latest research, published on Wednesday in Environmental Research Letters, found global sea-levels rising at a rate of 3.2mm a year, compared to the best estimates by the IPCC of 2mm a year, or 60% faster.

So that would be more like 9 inches by 2030 and 20 inches by 2050.

Add to a higher base sea level bigger storms like Hurricane Sandy, and Savannah and Jacksonville have a problem. Sure, Savannah is Continue reading →

Southern Company: let’s do the renewable energy study for Georgia

Mark Z. Jacobson's study shows offshore wind is plentiful from Virginia to Maine Let's do the study for Georgia! Southern Company brags about its private R&D:

Research & Development (since the 1960s)

  • Awarded more than $1.3 billion to conduct more than $3.8 billion of research and development.
  • Qualified for $412 million of investment tax credits for a 21st century coal plant being built in Mississippi.

OK, SO, let's see you do the study to show what we can really do with conservation, efficiency, wind, sun, and less natural gas than we have now. Sure, in the Georgia Bight we do have to contend with hurricanes. But a "great, big company" like SO should be able to focus its vaunted private R&D on that problem and solve it.

Maybe SO doesn't want to do that because the result might show there is no need for any coal plants, nor new natural gas plants, nor any nuclear plants, which would mean Georgia Power would have to give up its nuclear-funding rate-hike stealth tax and SO would have to give up its $8.3 billion loan guarantee. Hey, we might even need to change the 1973 Georgia Electric Territorial Act, and that might damage Georgia Power's guaranteed profit! Nevermind that Georgia Power and SO might make more profit if they got out in front on solar and wind power and a smart grid.

If SO won't do it, how about we elect some Public Service Commissioners and legislators who will? For jobs, energy independence, and profit, oh, and clean air and plenty of water!

All U.S. east coast electricity could come from offshore wind 3 seasons out of 4

Why build nukes when wind can provide 3/4 of our power? While Southern Company claims to be “a company that is engaged in offering solutions, not just rhetoric”, yet does nothing about wind off the Georgia coast, researchers in far California have demonstrated we can get 3/4 of all needed east coast electricity from offshore wind.

Bjorn Carey wrote for Stanford Report 14 September 2012, Offshore wind energy could power entire U.S. East Coast, Stanford scientists say

A new analysis by Stanford researchers reveals that there is enough offshore wind along the U.S. East Coast to meet the electricity demands of at least one-third of the country.

The scientists paid special attention to the Maine-to-Virginia corridor; the historical lack of strong hurricanes in the region makes it a favorable site for offshore wind turbines. They found that turbines placed there could satisfy the peak-time power needs of these states for three seasons of the year (summer is the exception).

“We knew there was a lot of wind out there, but this is the first actual quantification of the total resource and the time of day that the resource peaks,” said Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford who directed the research. “This provides practical information to wind farm developers about the best areas to place turbines.”

Mark Z. Jacobson already worked out a framework for powering the entire world from wind, water, and sun alone. The late John Blackburn, Ph.D., showed us how to power North Carolina with sun, wind, and hydro, plus less natural gas than NC uses now. Now Jacobson is working out the details of implementation.

New research shows Natural Gas far more dangerous for climate stability —Seth Gunning

Received yesterday on U.S. CO2 emissions lowest in 20 years: that's good and bad: natural gas is methane, after all. -jsq

Yet another comprehensive article. I might also add that one of the major down-falls (if not the most significant) of large-scale conversions to natural gas is the resources lifecycle methane emissions.

As your readers likely know, Methane is about twenty times as 'potent' a greenhouse gas as Carbon Dioxide. That is to say, it is far more efficient at trapping heat then Co2. So, less methane has a far greater impact on climate disruption then more Co2.

Natural Gas, from the point of combustion, releases about half the amount of Co2 released from burning coal, and about 30% of what's released in burning oil. To keep the benefits of reduced Co2 levels when switching from coal to natural gas, natural gas wells and transport lines must leak less then 2% of methane into the atmosphere. Recent research from Cornell is showing that Fracking wells are regularly releasing more then 4%, and often as much as 8% —far exceeding the 2% threshold— and thus making Natural Gas a far more dangerous resource for climate stability.

U.S. CO2 emissions lowest in 20 years: that’s good and bad

The good news: because utilities such as Southern Company are switching away from coal U.S. emissions of CO2 are the lowest they’ve been in 20 years. The bad news: they’re switching to natural gas, which not only still emits carbon dioxide, it pollutes groundwater through fracking, requires a lot of groundwater to do the fracking in the first place, and then uses more groundwater for cooling. But the further good news is cheaper energy sources drive out expensive ones, and wind and solar are already cheaper than nuclear and coal, and solar is already cheaper than natural gas. Oh, and solar and wind emit no CO2.

Kevin Begos write for AP yesterday, AP IMPACT: CO2 emissions in US drop to 20-year low

“There’s a very clear lesson here. What it shows is that if you make a cleaner energy source cheaper, you will displace dirtier sources,” said Roger Pielke Jr., a climate expert at the University of Colorado.

While conservation efforts, the lagging economy and greater use of renewable energy are factors in the CO2 decline, the drop-off is due mainly to low-priced natural gas, the agency said.

A frenzy of shale gas drilling in the Northeast’s Marcellus Shale and in Texas, Arkansas and Louisiana has caused the wholesale price of natural gas to plummet from $7 or $8 per unit to about $3 over the past four years, making it cheaper to burn than coal for a given amount of energy produced. As a result, utilities are relying more than ever on gas-fired generating plants.

Both government and industry experts said the biggest surprise is how quickly the electric industry turned away from coal. In 2005, coal was used to produce about half of all the electricity generated in the U.S. The Energy Information Agency said that fell to 34 percent in March, the lowest level since it began keeping records nearly 40 years ago.

And that’s why Southern Company (SO) turned towards natural gas: it’s cheaper! SO still prefers nuclear and coal before gas, as SO CEO Thomas A. Fanning keeps reminding us. But even SO couldn’t ignore “the revolution in shale gas”, which is cheaper prices through fracking. Solar PV costs dropped 50% last year alone. How long can SO ignore that?

“Natural gas is not a long-term solution to the CO2 problem,” Pielke warned….

Why would anyone not want to work on renewable safe and much less expensive solar energy, in the sunshine state?!

Or in the Empire State of the South, for that matter. You know, Georgia, the state where FPL Continue reading →

It’s only going to get hotter: time for solar power

Looks like the heat wave is going to continue for a while, according to NOAA’s maximum heat index forecasts. Reuters wrote today,

A heat wave baking the eastern United States in record temperatures is set to continue on Sunday after deadly storms killed at least 12 people, downed power lines from Indiana to Maryland and left more than 3 million customers without power….

Utilities in Ohio, Virginia and Maryland described damage to their power grids as catastrophic.

Millions without power due to no smart grid

We know the answer to this! Top story on CNN.com today: Millions without power as storms pound U.S. following record-setting heat

Nearly 4 million homes lost power early Saturday across the Midwest as a fierce line of thunderstorms and winds pounded the region after record-setting temperatures.

The storms moved east from Indiana through Ohio and into West Virginia, according to utility companies. Virginia was hit with power outages to more than 1 million homes.

The outages come as tens of millions in the central and eastern United States are battling a sweltering summer.

Thirty years ago the Internet demonstrated distribution and decentralization is the way to avoid widespread outages. That's what a smart grid would give us. I can say by experience that if many of those homes and businesses had solar panels with batteries, they could weather 10 hours or more of no grid power with no problem. My solar panels and batteries have done that for my house for years. Yours could too, and you could be selling excess power to people and businesses that don't have panels, if Georgia Power would let us change state law to let us.

And hey, with wind power, in a storm you'd have more power!

Temperatures Friday soared past 100 degrees Fahrenheit from Kansas to Washington, with scorching conditions expected to continue through the weekend and beyond.

It was 107 degrees in Macon, Georgia yesterday at 7:30 PM. So what's Georgia Power doing about solar power in Macon? Still studying it, according to Josephine Bennett in NPR a year ago:

Georgia Power's Carol Boatright says for 18 months researchers will collect data and then ask the following questions.

How about this question, Georgia Power and the Southern Company and Oglethorpe Power and all the EMCs: Will you wait until Georgia is without power until you deploy solar power, or get out of the way so we can do it ourselves?
