Quite simply if your aren't stressed by climate change you aren't paying attention. It is the biggest, most significant issue of the 21st century, everything else pales into insignificance besides the enormity of climate change.
Most of us of a certain age will be fine and probably our children will be, but our precious grandchildren and all the other precious grandchildren around the world are the ones who will have to have to deal with the consequences and pay the price of the folly, stupidity, denial and greed of earlier generations. And that includes all of us Grans. All we can do is the very best we can in our own lives, keep the issue on the political agenda, support local and national initiatives etc. We can all play our own small part. I'd rather be remembered for having tried than for living in a bubble of self indulgence and denial.
And believe me I do know how appalling Australia's record is on this issue and I work actively to try to change that.
