For what its worth, here's my take on warm/cold/hot weather changes.
It is widely accepted that a comet or very large meteor, or meteors exploding on Earth thousands of years ago, wiped out the dinosaurs (and maybe many other life-forms on this planet). The clouds that arose, went round the entire earth, blotting out the sun for many years, hence the ice-age. Eventually, the clouds dissipated and the sun started to come through again, heating up the planet enough, for life to begin again.
In 1980, in America, Mount St. Helens erupted and sent out massive clouds which went round the world. I remember, in 1981, people saying that our not-so-good summer was down to the eruption's clouds that blotted out the sun. That was just one volcano. Imagine the size of the explosions that did for the dinosaurs. If clouds caused by explosions were to blame for dead dinosaurs and a shitty 1981 summer, then you have to say that all the smoke from factories belching up towards the skies must be harming our ozone layers. If that is the case, what is the answer? Is a smoke-free world, with nuclear energy safe? Chernoble comes to mind, as does that nuclear power plant in Japan when they had that terrible tsunami around 8 years ago.
Wind farms? Do they rely on wind? What happens if there is no wind?
Solar panelling? What happens if there's no sun?
What about keeping the people on Earth nice and warm? The Tories and Nigel bloody Farage are both full of hot air.......could that help?
Tbh, I haven't got a clue what the answer is, for saving the planet. The trees in the rain forests in outer Botswana and other places that are chopped down in great numbers are being destroyed by man's greedy needs. Man is definitely the reason for their destruction.
