Am I an activist for caring about my grandchildren’s future? I guess I am
Greenhouse Neutral Foundation comment – I have long admired James Hansen as a person who cares for the future of all that we share our fragile planet with. The answers to all of the significant challenges we face in the imminent future is in OUR hands.
We need to accept this moral responsibility. The following article [...]

Science stunner: Vast East Siberian Arctic Shelf methane store destabilizing and venting
NSF issues world a wake-up call: “Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.”
March 4, 2010
Methane release from the not-so-perma-frost is the most dangerous amplifying feedback in the entire carbon cycle. Research published in Friday’s journal Science finds a key “lid” on “the large sub-sea permafrost [...]

NASA eyeballs glacial melt in Greenland
The Jakobshavn Isbrae glacier, one of the largest glaciers in Greenland, swiftly lost a 2.7-square mile chunk of ice between July 6 and 7, NASA announced late last week. The ice loss pushed the point where the glacier meets the ocean, known as the “calving front,” nearly one mile farther inland in a single day. [...]

The permafrost methane problem.
In 2008 when I wrote ZERO Greenhouse Emissions, I included a chapter ‘Mother Natures Super Salesman’ to attempt to get the point across that unless we decarbonise our activities in the short term Mother Nature would kick in some of her stores of carbon and methane. Many other facts were revealed and I would encourage [...]

Arctic Climate May Be More Sensitive to Warming Than Thought, Says New Study
A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth’s atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.
Led by the University of Colorado at Boulder, the international study indicated that while the mean [...]

Sea Ice in the Arctic Not Recovering: Another Critical Minimum Forecast
A critical minimum for Arctic sea ice can again be expected for late summer 2010, according to researchers.
Scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) in Bremerhaven and from KlimaCampus of the University of Hamburg have now published data in this context in the annual issue of [...]

Ocean Changes May Have Dire Impact on People
The first comprehensive synthesis on the effects of climate change on the world’s oceans has found they are now changing at a rate not seen for several million years.
In an article published June 18 in Science magazine, scientists reveal the growing atmospheric concentrations of man-made greenhouse gases are driving irreversible and dramatic changes to the [...]

Will Greenhouse Gas Emissions Increase Or Decrease?
The U.S. Energy Information Administration (EIA) thinks global carbon emissions will increase 43 percent by 2035 if major nations maintain the status quo as far as energy policies go and do not try to stop climate change. The EIA’s 2010 long-term global energy analysis predicts that energy use will increase 49 percent between 2007 and [...]

Climate change could make half the world uninhabitable
Greenhouse Neutral Foundation Comment: – Looking forward further into the future Scientist have suggested the upward movement of rising temperatures won’t just stop at the current upper levels suggested by the IPCC but will continue. As suggested by Mother Natures Supersalesman in his closing remarks in the book ZERO Greenhouse Emissions – excerpt

Climate Change Hits the Oceans
When scientists say the planet is warming, they usually point to rising air temperatures as proof. That’s reasonable enough, especially since the warmth of the air temperature affects us directly so we feel the change the scientists are measuring. But it’s also misleading: while the lower atmosphere has been gradually warming over the past 50 [...]
