I can remember back in the 1970s how, the Northern Hemisphere would be under miles of ice by the 1990s..
Is there climate change?, you bet there is.. are we, as humans responsible - no, nowhere as much as the media and politicians would have you believe.. from a technical standpoint, the Earth is still coming out of the last ice age (inter-glacier period) from ice cores samples, we know that before the last age, the Earth was a lot warmer than it is today.
The biggest factor for climate change is our Sun.. it will and always will drive our climate.. global warming is a natural cycle of our planet, just like ice ages are. There's nothing you can do, no amount of money is going to change it.. sit back, relax and enjoy whatever time you have on Earth because, long after we're all gone, there will still be climate change.
