Generational Amnesia
Why do so many people dismiss or underestimate environmental damage? Of course, there is the simple idea that Earth is so much larger than us we have a hard time understanding how we can damage it. This overlooks the fact that there are now a staggering 7 billions of us (that’s 7,000 millions!) Contrast that with the “only” 1.6B of us there were in 1900 and then add that we now have advanced technology...
Humanity falls deeper into ecological debt: study
Earth’s seven billion denizens — nine billion by mid-century — are using more water, cutting down more forests and eating more fish than Nature can replace, it said. via Humanity falls deeper into ecological debt: study.
Relocating Alaska Natives: The Climate is Changing Faster Than Disaster Management and Adaptation Policies | ThinkProgress
In 2008, I took a tiny cargo plane to the Inupiaq village of Kivalina, in the northwest of Alaska above the Arctic Circle. I had heard the village would be lost to climate change from erosion, which I imagined to be a slow, gradual, and predictable process. Touring the island and speaking to residents and government workers, I soon realized the erosion is actually often sudden, severe, and erratic, brought on by...

Great Barrier Reef Part 2: Climate Change Impacts
Coral reefs like the Great Barrier Reef depend on a narrow set of environmental conditions within which they prosper. At the heart of their biology, is a symbiosis that they form with tiny plant-like organisms known as dinoflagellates (commonly called zooxanthellae). This symbiosis is critical to the survival of corals and coral reefs, making possible the efficient trapping of sunlight by reef-building corals. This allows them a cheap source of energy with which...
Phosphate: A Critical Resource Misused and Now Running Low by Fred Pearce: Yale Environment 360
Phosphate has been essential to feeding the world since the Green Revolution, but its excessive use as a fertilizer has led to widespread pollution and eutrophication. Now, many of the world’s remaining reserves are starting to be depleted. by fred pearce Phosphate: A Critical Resource Misused and Now Running Low by Fred Pearce: Yale Environment 360.
Great Barrier Reef Part 1: Current Conditions and Human Impacts
What’s the current state of the GBR (i.e. is it really “in fine fettle”)? Despite being one of the best managed marine ecosystems worldwide, there is evidence that the ecological ‘health’ of the Great Barrier Reef has declined since the arrival of European settlers into the Queensland region. This evidence comes from a number of key sources. This area is not without its controversy, which is discussed elsewhere at Skeptical Science by Professor John Bruno...
Ocean life on the brink of mass extinctions: study | Reuters
(Reuters) – Life in the oceans is at imminent risk of the worst spate of extinctions in millions of years due to threats such as climate change and over-fishing, a study showed on Tuesday. Continue reading via Ocean life on the brink of mass extinctions: study | Reuters.
Yale Environment 360: Snowpack Decline in Rockies Has Rapidly Accelerated, Study Shows
Yale Environment 360: Snowpack Decline in Rockies Has Rapidly Accelerated, Study Shows 10 JUN 2011: SNOWPACK DECLINE IN ROCKIES HAS RAPIDLY ACCELERATED, STUDY SHOWS A new study says snowpack decline in the northern Rocky Mountains over the last 30 years has been more severe than at any other time in nearly 1,000 years. In an analysis of 66 tree-ring records, researchers from the U.S. Geological Survey (USGS) found that the average spring snowpack in the...
