Climate change is absolutely real. Been going on for YEARS! Don’t like it talk to the sun and oceans, throw in a volcano or two. This is the biggest bunch of horse crap ever perpetrated on mankind. Send kids to college raise them stupid and broke. We’ve gotta get to Mars to save ourselves. Smart like rock, sharp like door knob.
Real climatologists have studied climate change a lot, using real science. Ice cores can give us data going back to the first ice age, before we walked the earth. Other methods, such as isotope composition in oxides, carbonates, or gas inclusions, can take us back hundreds of millions of years.
The data are compelling: not only has climate often changed, the changes in the past have been far greater than any experienced recently, and they were not caused by dinosaurs burning coal.
Indeed, our climate has been more stable recently (it's called the Holocene) than at almost any previous epoch. But is plain fact, Earth's climate is not, technically, "stable". It is metastable. That is, it will tend back to equilibrium after small changes, but will at other times transition to a new, different, metastable state.
As it did in the Cretaceous, when the poles were warm swamps with basking alligators. And in the Carboniferous, 20 degrees warmer than today, and an atmosphere of 30% oxygen. A baking desert? No: with more abundant life than ever before.
The current panic is more than a scam: it is often a fraud. Canada is an example. It has warmer bits and colder bits. Then one day the government turned off many of the permanent temperature recorders in the colder bits. Presto! Canada is warming up.
