What's up with thunderstorms lately? It's like non-stop lightning, There isn't 2 seconds that go by without a strike, and the strikes themselves last around a second each, one I saw lasted over 2 seconds.
And there's not that much rain, it only starts to rain when the storm starts passing by. but it's totally dry on it's front. And also there's a storm like every other day.
Could it be that since CO2 is such a big molecule, that maybe it can carry a lot more charge and thus lightning gets stronger?
Also there's so much thunderstorms where it only in the clouds, no ground strikes. I don't remember any like that happening 10 years ago

If you gave your location, a more specific answer could be provided. Frequency of lightning in Cape Town, RSA is a lot different that Anchorage, AK, USA.

There are roughly 5 to 10 times as many flashes that remain in the cloud as there are flashes which travel to the ground, but individual storms may have more or fewer flashes reaching ground...
Now, what are you concerned about?

I wasn't conserned, I was trying to chat... you know... a thing humans do.

I thought lightning was essentially instant. and it is just the eye see's it for longer because it overloads the sensors in the retina.
Lightning is not just with rain.
Hydrogen nuclear explosions have lightning.

Hydrogen nuclear explosions have lightning.
Volcanoes too.
Hunga Tonga Volcano Sparked the Most Intense Lightning Storm Ever Recorded. Last year’s eruption produced a raging storm at unprecedented altitudes, with 2,600 lightning flashes per minute at its peak.

Yeah well I don't think overloading your eye would make you perceive the lightning strike, get dim, then slowly increase in intensity over ~500ms, only then fade away.
It was interesting to also see some of the strikes "oscillate" between 3 and 10hz although I probably wouldn't have seen ones that oscillated at higher frequencies than that. Didn't seem like that random which is odd.

That's because the photons hug the big CO2 molecules.

I noticed lot more lightning storms in my area too this year. Mostly in June/July. It seems to have slowed down now as summer is starting to wrap up. Leaves are already starting to change.
There was one particular one that was very odd. I kept seeing flashes outside but there was no rain or thunder. I went outside to see what was happening then realize it was in fact lightning. I ended up going out to sit at a table at the nearby park to watch it. There was some very big strikes once in a while but I'd say like every 30 seconds there was a strike. Some seemed to be going up from the clouds instead of down. At one point there was a VERY close strike, that made me jump. It was incredibly loud. I decided it was time to go back inside.
Got inside and notice the heat was on. I then checked my hvac control system and all my sensors were reading wonky. The main one that controls the hvac was at 0. I had to reset the whole system, full power down and power back up to get it to work properly again. It seems to me the strike was close enough that it affected the system. This is fully custom, and I guess I should probably read up on input protection on sensor lines as it's not the first time I've had incidents involving static electricity. But it was rather interesting that it happened.

@Red Squirrel
"Summer" lightning is common in Southwestern USA. The first time I saw it was as a child on a train trip from SoCal to the Midwest. Part of that trip was us at night across Arizona and New Mexico.
