Climate

The overwhelming evidence of human-caused climate change documents both current impacts with significant costs and extraordinary future risks to society and natural systems. The scientific community has convened conferences, published reports, spoken out at forums and proclaimed, through statements by virtually every national scientific academy and relevant major scientific organization — including the American Association for the Advancement of Science (AAAS) — that climate change puts the well-being of people of all nations at risk.

Surveys show that many Americans think climate change is still a topic of significant scientific disagreement.i Thus, it is important and increasingly urgent for the public to know there is now a high degree of agreement among climate scientists that human-caused climate change is real. Moreover, while the public is becoming aware that climate change is increasing the likelihood of certain local disasters, many people do not yet understand that there is a small, but real chance of abrupt, unpredictable and potentially irreversible changes with highly damaging impacts on people in the United States and around the world.

All margins of ice sheet now unstable—and contributing to sea level rise

osu.edu - March 17, 2014

COLUMBUS, Ohio—An international team of scientists has discovered that the last remaining stable portion of the Greenland ice sheet is stable no more.

The finding, which will likely boost estimates of expected global sea level rise in the future, appears in the March 16 issue of the journal Nature Climate Change [DOI:10.1038/NCLIMATE2161].

From South America to South Asia, a new age of unrest is in full swing as industrial civilisation transitions to post-carbon reality

If anyone had hoped that the Arab Spring and Occupy protests a few years back were one-off episodes that would soon give way to more stability, they have another thing coming. The hope was that ongoing economic recovery would return to pre-crash levels of growth, alleviating the grievances fueling the fires of civil unrest, stoked by years of recession. . .

. . . The recent cases illustrate not just an explicit link between civil unrest and an increasingly volatile global food system, but also the root of this problem in the increasing unsustainability of our chronic civilisational addiction to fossil fuels. . .

. . . Of course, the elephant in the room is climate change.
