Abrupt climate changes, such as the collapse of the West Antartic Ice Sheet, the rapid loss of the Greenland ice sheet or large-scale changes of ocean circulation systems, are not considered likley to occur in the 21st century, based on currently available model results. However, the occurrence of such changes becomes increasingly more likely as the perturbation of the climate system progresses.
Paleoclimatologists have spotted times in the deep past when the current slowed quickly and dramatically, cooling Europe by 5 to 10 degrees C (10 to 20 degrees F) and causing far-reaching impacts on climate. Modelers have tried to predict how human-caused climate change might impact the Atlantic current, and how its slowdown might muck with the world’s weather even more. But years of intensive peering at this question haven’t yet provided much clarity.
Now, debate is raging about whether the recent Atlantic slowdown has been triggered by climate change, or is just part of a normal cycle of fast and slow currents. New studies in the last few years and months have come out supporting both prospects. please see the link

We are very close to abrupt climate change, less than a decade.

Given the expected feedbacks and delayed effects of emitted GHGs, I have concluded that we WILL lose the Arctic sea ice. The world is not ready for the pace of change in climate that we can expect.
Green tech alone cannot save us:

And this is part of a complex story:

First we must do the mental and emotional work within ourselves to realize these things. It's difficult and scary. But a growing number of scientists are following the data. Hopefully we can network together to build awareness and facilitate adaptation to abrupt climate change.
