The impacts are increasingly being felt everywhere – bigger storms in the Midwest, soggy summers in England, drought in Colorado. But nowhere on the planet are the impacts as dramatic as the Arctic, and the ice cap is a prime example.
If you’re sweltering in New York or Miami or Los Angeles, the only ice you’re probably thinking about is the stuff melting fast in your drink.
But up in the Arctic, the ice pack is on pace for another record low. Scientists won’t know for sure until mid-September, the end of the North’s melt season. But two snapshots, one from July 21, 1979, the other from July 21, 2014, show the change.

And here, changes in Arctic (northern) sea ice during the same 1979 to 2012 period.

During the second half of June, the rate of sea ice loss in the Arctic was the second fastest in the satellite data record. As a result, by the beginning of July extent fell very close to two standard deviations below the long-term (1981 to 2010) average.

I’ve reported on clashes between clean energy activists and Utilities in Georgia and Arizona. Other battlefield states emerging as the solar/renewable wave moves across the country. What we’ve seen so far is that the overwhelming popularity of renewable energy has overcome big money and big clout from utilities and dirty energy advocates like ALEC and Americans for Prosperity.
Look for more in the Southwest and Southeast, gradually moving northward as solar prices continue to drop.
At some point, one or more states will create a solution that will become the template.
Below, review Skip Pruss on the “Value of Solar” initiative that Minnesota has created.
North Carolina has become one of the hottest states in America for solar power, ranking third in the nation for new photovoltaic installations in fourth quarter 2013 and first quarter 2014. But a regulatory fight pitting solar industry against big utilities is underway, and it could effectively end new utility-scale solar additions.
Every two years, the North Carolina Utilities Commission reviews how it calculates the “avoided costs” (the amount utilities would have to pay to generate or buy electricity elsewhere) of clean energy.
This time though, regulators are reviewing both avoided costs and the maximum size of renewable generation systems eligible for standard pricing – a regulatory process that could “have the effect of significantly reducing, if not eliminating” new solar installations in North Carolina.

Rainforest Connection (RFCx) transforms recycled cell-phones into autonomous, solar-powered listening devices that can monitor and pinpoint chainsaw activity at great distance.
This changes the game by providing the world’s first real-time logging detection system, pinpointing deforestation activity as it occurs, and providing the data openly, freely, and immediately to anyone around the world.
For the first time on a scalable level, responsible agents can arrive on the scene in time to interrupt the perpetrators and stop the damage, and the world can listen in as it occurs.

Everyone that was alive can remember where they were when they heard of this.
From the Description:
Apollo 11 landed on the Moon on July 20th, 1969, a little after 4:00in the afternoon Eastern Daylight Time. The Lunar Module, nicknamed Eagle and flown by Neil Armstrong and Edwin “Buzz” Aldrin, touched down near the southern rim of the Sea of Tranquility, one of the large, dark basins that contribute to the Man in the Moon visible from Earth. Armstrong and Aldrin spent about two hours outside the LM setting up experiments and collecting samples. At one point, Armstrong ventured east of the LM to examine a small crater, dubbed Little West, that he’d flown over just before landing.
The trails of disturbed regolith created by the astronauts’ boots are still clearly visible in photographs of the landing site taken by the Lunar Reconnaissance Orbiter (LRO) narrow-angle camera (LROC) more than four decades later.
LROC imagery makes it possible to visit the landing site in a whole new way by flying around a three-dimensional model of the site. LROC scientists created the digital elevation model using a stereo pair of images. Each image in the pair shows the site from a slightly different angle, allowing sophisticated software to infer the shape of the terrain, similar to the way that left and right eye views are combined in the brain to produce the perception of depth.

Someone pointed me to the amusing tweet by the deranged blogger who goes by the name “Steven Goddard”, fresh from the Heartland Climate Denial conference and feeling his oats apparently, @ Meteorologist Heidi Cullen.
Got me thinking there needs to be an Arctic ice Update. Fortunately Greg Laden has already given us one.
Yup, it’s melting.
As it does every summer, the Arctic Sea ice is melting off. Over the last several years, the amount of sea ice that melts by the time it hits minimum in September has generally been increasing. So, how’s it doing now?
The graph above shows the 1981-2010 average plus or minus two standard deviations. Before going into more detail than that, you should look at the following graphic.

I have some good news and some bad news.
New data released Thursday by the International Research Institute for Climate and Society—a climate forecasting partnership between Columbia University and NOAA—shows that while ocean temperatures in the tropical Pacific are still above normal, the atmospheric response has so far been sluggish. After an impressive ramp upearlier this year, that means the coming El Niño is increasingly likely to fall a bit flat.
What’s going on is relatively straightforward: El Niño is a phenomenon that occurs simultaneously in the ocean and atmosphere, usually initiated by a subsea sloshing of warm water toward the typically cooler Eastern Pacific. That part has already happened. Since the Pacific is so huge, the gradual emergence of a big swath of warmer-than-normal water during an El Niño eventually prompts something else: a reversal in the local trade winds, which can shift weather patterns worldwide. That’s the part we’re still waiting on. This process needs a reinforcing shot of westerly winds (counter the trade winds’ typical direction) to help dampen the cold water thatnormally springs up from deep below the ocean’s surface in the East Pacific. So far, the westerly winds have not come, and cold water is beginning to eat away at the burgeoning El Niño.
According to the IRI, the most likely scenario now is a weak-to-moderate El Niño:
While forecasts of strength still have uncertainty, we think a weak or moderate event more likely than a strong one, and more likely than no event at all. A weak event now appears just slightly more likely than a moderate one.
-Meanwhile, in California, new data on Thursday showed the state’s epic drought has continued to worsen. More than 80 percent of California is now classified as under “extreme” or “exceptional” drought. The prospect of a weaker El Niño bodes poorlyfor heavy drought-busting rains along the West Coast this winter.
