Past the Tipping Point

'It may already be too late to avoid major irreversible changes to many marine ecosystems. As history has shown us, these marine-based changes could have major earth-system consequences,' the scientists conclude.

It seems that as long as western society continues to function sufficiently for us in the north to retain some degree of comfort, the needed determination will never quite arrive. Thirty years of Permaculture activity are a case in point. We live with one foot in our feel-good gardens, the other in the supermarket. On the one hand we’re feebly preparing for the future, with the other we’re bringing it upon ourselves much sooner than we otherwise might. We still live as if we’re standing on an inflatable planet, continually postponing the systemic change that needs to occur.

"Recent observations show that greenhouse gas emissions and many aspects of the climate are changing near the upper boundary of the IPCC range of projections. Many key climate indicators are already moving beyond the patterns of natural variability within which contemporary society and economy have developed and thrived. These indicators include global mean surface temperature, sea-level rise, global ocean temperature, Arctic sea ice extent, ocean acidification, and extreme climatic events. With unabated emissions, many trends in climate will likely accelerate, leading to an increasing risk of abrupt or irreversible climatic shifts."

"...in the northeastern U.S., winter temperatures have increased by 4 degrees F since 1970; in the Pacific Northwest, the depth of the Cascade Mountain snowpack on April 1 has declined by 25 percent over the last half century, while spring runoff from the Cascades now occurs nearly a month earlier than 50 years ago; and in Alaska, winter temperatures have increased a stunning 6.3 degrees F in the last 50 years."
