Toxic, Oxygen-Depleted Oceans May Have Caused a Mass Extinction Event Changes in the ocean may have pushed some species over the edge 200 million years ago. Scientists have discovered that oxygen-depleted toxic oceans had a key role in a mass extinction event during that time. [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]

They saw "birds entering the solar flux and igniting, consequently become a streamer," for the smoke plume that comes from birds that ignite in midair. BrightSource concentrated solar plant is a "mega-trap" for wildlife, with the bright light of the plant attracting insects, which in turn attract insect-eating birds that fly to their death in the intensely focused light rays. Estimates range as high as one streamer every two minutes at a single plant, though this is disputed. A Federal report (PDF) is "occasionally gruesome".
"Novels are no use at all in days like these, for they deal with people and their relationships, with fathers and mothers and daughters or sons and lovers, etc., with souls, usually unhappy ones, and with society etc., as if the place for all these things were assured, the earth for all time earth, the sea level fixed for all time."

Years of Living Dangerously is a star-studded 9-part investigative documentary on the real impacts of global warming around the world. The first episode will air on April 13, but it is now freely available online (first link, 1-hour). Series backers and producers include James Cameron, Jerry Weintraub and Arnold Schwarzenegger. The Globe says it's "a lavish, gripping production focused on the real effect of climate change in real people’s lives around the world."

"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]

Stanford University Professor of Civil and Environmental Engineering, Mark Z Jacobson, claims that worldwide re-powering with Wind, Water, and Solar (WWS) energy, rather than continuing the use of fossil fuels and nuclear power, would save millions of lives per year from pollution, help avert disasters related to global warming, and increase worldwide economic, social, and political stability. He has a plan to achieve this goal. [more inside]

And glacial archaeology is becoming so much of a thing that it's getting its own scholarly journal.
So much rain fell on Australia during 2010-11 that global sea levels dropped, rather than normally rising. Australia has large basins from which rainwater doesn't drain (well). Australia is giving it back as evaporation and sea levels are on the rise again thanks. The record breaking rainfall was attributed to global warming.
