Tesla Powerwall Battery Economics: Almost There - "Elon Musk announced Tesla's home / business battery today. [video] tl;dr: It'll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market... That said, for large scale grid deployment (outside of the home), it still looks like flow batteries and advanced compressed air are likely to be far cheaper in the long run." [more inside]
The Chinchorro mummies are found in northern Chile and southern Peru; the oldest of them date to thousands of years before the first Egyptian mummies. Some of them mummified naturally, but most were intentionally mummified. The hot, arid conditions of the Atacama desert aided in this process. However, these mummies are now the latest victims of climate change, as increased humidity encourages bacterial growth that is transforming them into black ooze.
Comparing photographs of glaciers from the 1920's to today: Repeat photography is a technique in which a historical photograph and a modern photograph, both having the same field of view, are compared and contrasted to quantitatively and qualitatively determine their similarities and differences. The following sections depict how this technique was used at a number of locations in Alaska... to document and understand changes to glaciers and landscapes as a result of changing climate.

Treading Water by Laura Parker [National Geographic]
Phil Stoddard, in his third term as mayor of South Miami, is one of the few politicians willing to talk about when that time might come... He drew a graph with three lines that show population, property values, and sea level all rising. Then abruptly, population growth and property values plummet. “Something is going to upset the applecart,” he says. “A hurricane, a flood, another foot of sea rise, the loss of freshwater. People are going to stop coming here and bail.”[more inside]
In the 21st century, it almost goes without saying the past year was the hottest year on record. But it's worth mentioning 2014 was the hottest ever recorded, according to NASA and NOAA who independently confirmed. Drum roll: it was the 38th consecutive year of above-average temperatures. 14 of the 15 warmest years on record have occurred since 2000. Nobody born since 1976 has experienced a colder-than-average year on Earth. The coldest spot on Earth during 2014 (on average) was the eastern half of the United States. The hottest on average was most of Europe. British wine growers rejoice. [more inside]

The Yamal Crater (previously) mysteriously appeared on the Yamal Peninsula in northern Siberia sometime in early 2014. Thought to be the result of methane accumulation in thawing permafrost, when first discovered the giant hole was too dangerous for people to enter. Now that the ground has frozen, scientists have explored the hole and released a a set of otherworldly photographs documenting their expedition.
All these grown-up monsters for my grown-up mind, they are there in the nights I wake up terrified and taunted by death. When I feel so small and broken, when despair and terror take me, I have a secret tool, a talisman against the night. I don’t use it too often so that it doesn’t lose its power.[more inside]

"In October 2013, Drs. Tim Perkins and Abby van Den Berg of the University of Vermont’s Proctor Maple Research Center, revealed the findings of a study at a maple syrup conference in New Brunswick, Canada that sent waves through the industry. In 2010, they were studying vacuum systems in sap collection operations. Based on the observation that one of the mature trees in the study that was missing most of its top was still yielding high volumes of sap, they hypothesized that the maples were possibly drawing moisture from the soil and not the crown. Previously, they had presumed that the sap dripping from tap holes was coming from the upper portion of the tree. But, if the tree was missing most of its crown then, they surmised, it must be drawing moisture from the roots. ... They realized that their discovery meant sugarmakers could use saplings, densely planted in open fields, to harvest sap. In other words, it is possible that maple syrup could now be produced as a row crop like every other commercial crop in North America." [more inside]

The last decade (2001-2010) was the warmest on record. According to The UN World Metereological Organisation's report, the average land and ocean-surface temperature for 2001-2010 was estimated to be 14.47°C, or 0.47°C above the 1961-1990 global average and +0.21°C above the 1991-2000 global average (with a factor of uncertainty of ± 0.1°C).

Scripps Institute of Oceanography projects that next month its monitoring station will for the first time measure CO2 at 400 parts per million. Atmospheric CO2 has risen from 280 parts per million before the Industrial Revolution. 400 ppm is an arbitrary milestone that we'll blow right past on our way to 450 ppm within a few decades. This is an unprecedentedly fast rate of increase and it's getting faster. Not all measuring stations are exactly the same: A NOAA station in the Arctic measured CO2 at 400 ppm last year.

When conservative pundits write about climate change, they're more likely to mention Al Gore than science.
The prospects of keeping climate change below that (2-degree goal) are fading away. Scientists track carbon pollution both by monitoring what comes out of factories and what winds up in the atmosphere. Both are rising at rates faster than worst-case scenarios that climate scientists used in their most recent international projections.
"A theory quickly emerged: that believers in climate science had been the main people taking Dr. Lewandowsky’s survey, but instead of answering honestly, had decided en masse to impersonate climate contrarians, giving the craziest possible answers so as to make the contrarians look like whack jobs.

How can we get CO2 out of the atmosphere? Get it out of the sea first. Making jet fuel from seawater is a pretty cool -- albeit energy intensive -- trick. But applying the same science to scrub CO2 out of seawater, where it is more densely concentrated than in the atmosphere -- and, by doing so, to reduce atmospheric levels of CO2 back to acceptable levels -- that's a game saver.
"what would it take to draw atmospheric carbon down to 350 ppm with just this technology? . . . we would require the power of about 700 AP-1000 nuclear reactors. At the Chinese cost of $1.3b apiece and an 80 year lifetime this would cost a bit over $1 trillion dollars. That sounds like a lot of money. But its only about the cost of America’s 2003 Iraq War spread over the century, so I guess it’s a question of priorities."
It's so hot in Australia they've added a new color to the weather map, a Tasmania-sized deep purple blob 50 degrees or more (123 F). In the USA 2012 was the hottest year ever recorded, smashing through previous records by a healthy margin. 2012 was also the second-worst on a measure called the Climate Extremes Index, surpassed only by 1998. Globally, 2012 is expected to be ranked as the eighth-warmest year on record, with that announcement coming later in the month. "Climate change has had a role in this,” said Jake Crouch, a climate scientist at NOAA.
