I'm old enough to remember when 350ppm was the target max -

The good news is that the very recent curtailment of vehicle and air travel due to the pandemic is already having measurable results. For example -

Scary times on the west coast. Hope everyone is staying safe from the fires.

No wildfires in Pittsburgh, but we can see the smoke from here :shock:. It actually cooled us off about 10-15 degrees and made for some interesting sunsets. Today’s high was 69 F, last Saturday (9-12) was in the mid-80’s.

Nice photo. Our sun as been obscured far more for the last week. Last Wednesday when it was really dark during the day my solar panels put out only 1.4kWh for the whole day, compared to their usual 60kWh at this time of year. I cannot believe that climate disruption is even being questioned - the whole world should be mobilizing to address this issue (like we did back in the '90's to take care of the ozone hole). Future generations will be cursing us...

My panels are surprisingly productive, making around 54 kWh for each of the past two days when I would expect about 40 kWh (when the sun does shine through, it looks like it did during our solar eclipse a few years ago, sunny but dim).

The large solar project I was a part of last year (pictures below) has exceeded production estimates considerably. I guess panels laying flat out-perform angled panels considerably in cloudy weather. What I’d give just to have one section of that array at my house; power output in the rain is higher than my system is capable of producing at full output.

A friend of mine is in San Luis Obispo and reports a lot of smoke, and from what I gather, he’s upwind of the fires.

I had noticed that, as my flat panels on the boat always seemed to put out more (percentage-wise) than my angled panels at home.

Yay, this morning our AQI = 0, what a difference when compared to the horrors of last week! But it's only temporary, as the wind is going to shift again...
