“Vaisala, an environmental monitoring company that tracks lightning around the world, reported 7,278 lightning strokes occurred last year north of 80 degrees latitude, nearly twice as many as the previous nine years combined. Arctic lightning is rare — even more so at such far northern latitudes — and scientists use it as a key indicator of the climate crisis, since the phenomena signals warming temperatures in the predominantly frozen region. Lightning occurs in energetic storms associated with an unstable atmosphere, requiring relatively warm and moist air, which is why they primarily occur in tropical latitudes and elsewhere during summer months.” 
Global Warming creates more humidity in the air to form droplets and ice crystals, and with more heat in the oceans and in the air there are more and stronger updrafts — forming clouds, being storms — to loft and freeze that humidity. The rapidity of that process (thunderclouds) is the source of the charge separation that results in lightning: static electricity created by friction and held by ice crystals high and low.
How about geo-engineering to reflect sunlight back into space, and cool the Earth? A friend asked: Is Dr. Ye Tao’s mirrors-on-the-ocean-surface scheme to reduce solar influx and thus reduce global warming reasonable? 
My initial reaction: It’s like wearing a thicker helmet so you can keep playing Russian Roulette.
My pal reacts: Indeed, but it appears to buy time. Would you agree with that?
My testy reply (and, he is a good guy) is based on my entrenched anti-geo-engineering bias (if you want to call it a bias), and my pessimistic assessment about “us” really ever responding to global warming climate change (GWCC):
I have no doubt that every technological scheme possible will be tried, and that no reason will ever be found for curbing CO2 emissions or ever ending our fossil fuel extraction (a.k.a. “business as usual”). In fact, those technological ideas will be used as justifications for continuing to emit CO2 (and greenhouse gases) at current and even higher levels.
As long as CO2 is in the atmosphere, it will act as an absorber of infrared radiation (IR, heat energy) radiated upward from the Earth’s surface — land and water — day and night.
Water vapor and organic vapors also capture IR, and there are increasing concentrations of these with continuing anthropogenic greenhouse gas emissions, and consequently increasingly higher biosphere temperatures: regional, planetary average, and very (very) long-term.
Reducing sunlight shining down to the ocean means reducing light energy used by plankton for photosynthesis, and they are the largest generator — larger than land-based plants — of oxygen (O2) for our atmosphere, and our breathing:
“Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.” 
Also, plankton is the base of the food chain in the oceans, and all higher forms of life depend on them for survival (even us, for seafood). Baleen whales, rays and whale-sharks scoop up plankton directly, and are thus huge repositories of captured carbon, whose bodies after death sink to the ocean bottom and slowly become part of the chalky seabed rocks (“sequestration” done automatically by Nature). Since oceans are about 3/4 of the Earth’s surface, if we kill them we die quickly (geologically speaking). Life on land will not survive with dead, acidified oceans.
As I said, I do not see “us” ever cutting back on our CO2 emissions (so, keep shooting ourselves in the head), but I do see “us” using every conceivable scheme — especially if it can be patented and someone can make big money on it, like with COVID vaccines — to “mitigate” (thicken up our Russian Roulette protective helmets) so we can keep on burning up the fossil fuels, making the big bucks, having the profitable wars, and having an exponentially growing capitalist “good life.” Until it isn’t.
So, yeah, “it buys us time.” It’s so hard not to keep shooting ourselves in the head, isn’t it?
