All aboard, please take your seats and fasten your seatbelts. There is a 25% chance this plane will crash.

By Bob Williamson – Greenhouse Neutral Foundation
The reality of that welcome to us would be our reply, “I’m not getting on this flight!”
Yet we are all in fact on that flight with climate change and the plane has taken off.
Much has been promoted in the media lately that climate change science is somehow conspiring to [...]

The breakaway of a Mammoth iceberg scientist say could alter ocean circulation

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 [...]

The colder side of the Antarctic Peninsula now shows signs of melting

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 [...]

Antarctic Ice Shelf Collapse Possibly Triggered by Ocean Waves

Depicting a cause-and-effect scenario that spans thousands of miles, a scientist at Scripps Institution of Oceanography at UC San Diego and his collaborators discovered that ocean waves originating along the Pacific coasts of North and South America impact Antarctic ice shelves and could play a role in their catastrophic collapse.
Peter Bromirski of Scripps Oceanography is [...]

Tipping Point? West Antarctic Ice Sheet Could Become Unstable as World Warms

A new study examines how ice sheets, such as the West Antarctic Ice Sheet, could become unstable as the world warms.
The team from Oxford University and Cambridge University developed a model to explore how changes in the ‘grounding line’ — where an ice sheet floats free from its base of rock or sediment — could [...]

Get ready for seven-foot sea level rise as climate change melts ice sheets

The IPCC’s 2007 report missed out the melting of the Greenland and West Antarctic ice sheets which would be the key drivers in dramatic sea level rises.
The reports from the Intergovernmental Panel on Climate Change (IPCC) are balanced and comprehensive documents summarizing the impact of global warming on the planet. But they are not without [...]

An Ice Shelf the Size of Rhode Island Breaks Up in Just 24 Hours 3 time-lapsed photos

3 time-lapsed photos show the incredible disintegration of the Filchner ice shelf in Antarctica.
Within a 24-hour space, an area of sea ice larger than the state of Rhode Island broke away from the Ronne-Filchner Ice Shelf and shattered into many smaller pieces. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua and Terra satellites captured [...]

Tipping Elements in the Earth System: How Stable Is the Contemporary Environment?

A Special Feature of the Proceedings of the National Academy of Sciences presents the latest scientific insights on so-called tipping elements in the planetary environment. These elements have been identified as the most vulnerable large-scale components of the Earth System that may be profoundly altered by human interference. If one or more of those components [...]
