Dense smoke in Sydney

The smoke just about blotting out the sun along the beaches by 0630

Hello Friends,

What can one say? The smoke is dreadful this morning. Visibility is maybe 300 m at RealSurf HQ as I write this. And it doesn’t look like getting better until (maybe) after the south change hits.
Needless to say, this isn’t a morning to be engaging in vigorous exercise – even for those of us fortunate enough not to have any sort of respiratory condition – this morning everyone has a respiratory condition. It’s just as well that there really aren’t any waves to justify getting wet.
We’re going to a high of 36C today, so it must be hellish out on the fire grounds. So grateful for those volunteers risking their lives on our behalf.
The climate my generation grew up with is no more. We are on a new course now, away from anything our species has ever known. Most of us get this, but the 10% or so in denial or dismissive of the terrible danger to our children are over represented among our decision makers.
Stay safe everyone.
