BALTIMORE — Microbes living under ice sheets in Antarctica and Greenland could be churning out large quantities of the greenhouse gas methane, a new study suggests.
In recent years scientists have learned that liquid water lurks under much of Antarctica’s massive ice sheet, and so, they say, the potential microbial habitat in this watery world is [...]

For those who have read my book ZERO Greenhouse Emissions – The Day the Lights Went Out – Our Future World, the reports this week by the science community of the discovery of methane release from thawing methane clathrates from the East Siberian Arctic Shelf will come as little surprise. In chapter 9 Mother Natures [...]

From the News desk at the BBC – A review from the UK Met Office says it is becoming clearer that human activities are causing climate change.
It says the evidence is stronger now than when the Intergovernmental Panel on Climate Change carried out its last assessment in 2007.
The analysis, published in the Wiley Interdisciplinary Reviews [...]

This report fron the New York Times follows up on other reports posted this week by the Greenhouse Neutral Foundation.
Climate scientists have long warned that global warming could unlock vast stores of the greenhouse gas methane that are frozen into the Arctic permafrost, setting off potentially significant increases in global warming.
Now researchers at the University [...]

Article and images courtesy of Reuters – Like many low-altitude glaciers, it’s steadily melting, shrinking two miles over the past 200 years as it tries to strike a new balance with rising temperatures.
At the Kenai Fjords National Park south of Anchorage, managers have learned to follow the Exit and other glaciers, moving signs and paths [...]

Reported in Science this tipping point on the destabilization of methane clathrates was detailed as a possible consequence on Arctic warming in ZERO Greenhouse Emissions. The book by Bob Williamson of the Greenhouse Neutral Foundation suggests this as one of multiple interlinked outcomes. It is required reading to determine how action must now be focused, [...]

As discussed in some detail in the book ZERO Greenhouse Emissions, the climatic impacts of warming world provide the opportunity for invasive species such as the Pine Bark Beetle to migrate to new habitate.
Small excerpt:
“Colorado’s Rocky Mountains are fighting a losing battle to pine bark beetles as they decimate millions of trees at altitudes they [...]

The release of more than 370 billion tons of carbon (GtC) from buried early biospheres, adding more than one half of the original carbon inventory of the atmosphere (~590 GtC), as well as the depletion of vegetation, have triggered a fundamental shift in [...]

An iceberg the size of Luxembourg knocked loose from the Antarctic continent earlier this month could disrupt the ocean currents driving weather patterns around the globe, researchers said Thursday.
While the impact would not be felt for decades or longer, a slowdown in the production of colder, dense water could result in less temperate winters in [...]

A new report of ice shelf changes along the southern, colder part of the Antarctic Peninsula reveal some dramatic losses of ice over the last 63 years that the researchers attribute to global warming.
The report by the U.S. Geological Survey (USGS) compiles a wide variety of maps, aerial photos and satellite imagery to create a [...]
