Wrong the ice hasn't increased. Antarctica. Big loss colossal loss. Warming ocean. Resulting in so many issues and coral loss. Which Glaciers have returned. None. Wildfires in the Arctic; Sweden, Canada, Siberia last year. Lichen growing from increased temperatures in Greenland preventing the ice returning, causing increasing warming. Etc etc.

Yes on a global model, this could happen real quick. Regardless of humans. A simple eruption let us be historic and use Vesuvius. It blows errupting big wiping out the surrounding area. It sends megatonnes of ash into the atmosphere, the planet cools, temperature plummets for a few years, possibly even decades of extreme weather. European agriculture immediately doesn't grow for the masses it feeds. Resulting in a cascading effect globally. Now let us get exciting and trigger an ice age off of a few volcanoes or a super volcano erupting. Perhaps we can also try solar cycles. Where the sun causes a period of cooling from lessening sun spots, like an extended period of warming from abundant spots lasting centuries. Again an ice age from solar cycles, by a solar flare causing the unspeakable. Even a potential geomagnetic solar storm not directly hitting the planet could wipe out technology, planes satellites, and unsheilded electronics and most electricity depending on that hit. Whoops. An asteroid impact instantly triggering the ice age. Let us try our orbit, true north is wobbling it is increasingly moving away from past alignment, this could cause a polar shift where the ice age simply occurs no matter what. It was always a cycle generated by factors humans had no other control of. Despite of them increasingly speeding up any effects. Today they think they're real special because they buy into more corporate bullshit. Where gee Einstein the globe wasn't warmed before electricity, why are they buying more of it to stop the warming. It wasn't until we had even more stupid technology that we had the climate change. Stupid technology mass producing morons. Like let us set up the WWF so there are even less animals. Or Oxfam so there is millions more starving and billions more needing charity. Stupid. Except it paid some cunt more to pretend to care about just how ignorant they are. Like renewables. Although it has little consequences on most of those other factors naturally occurring regardless.

You are suggesting the ice returns. Not today. There is increasing loss and a warmer globe.

The solutions are absurd as stated. They don't even work in extreme weather. Electricity fails everytime a storm hits, like in Texas. Where the grid went down from useless renewables. If you get rid of fuel, you freeze. Your car don't work either. Idiotically and like Santa, it is a tale you spin to Greta, renewables are powered by the sun and wind and not by the fossil fuels making them where they also need a fossil fuel back up for when there is no sun or any wind. But for the love of the planet why are you using more products with a lessening lifetime, using far more consumption if you are eco, and why does it cost so much more, because it is Christmas and she wants another present which lasts until next year like another stupid Tesla or iPhone.
