Didn't much of the USA used be covered by this land ice? Didn't large parts of the earth goes to desertification? Hasn't all this change occurred
before man ever burnt carbon or even existed? And weren't the changes much bigger than what we are seeing now?
Yes, but we don't fully know what caused them. Its very possible that it was caused by something like a set of volcanic eruptions, or asteroid
impacts, throwing massive amounts of ash/dust into the atmosphere. This would cause something akin to a “nuclear winter”.
We know that something happened that cause a lot of debris in the atmosphere at one point, because worldwide you can find the KP Boundary.
Cretaceous–Paleogene (K–Pg) boundary
Leave it to man and his ego to think that he can heavily influence natural processes that have been occurring since the earth came into
We absolutely have an effect on the climate. Deforestation, increasing levels of cement, building of dams, rerouting of rivers, are all proven to
cause local to regional climate change.
The idea that its coming from the sun was looked at by NOAA. Now does it really look like that is the case based on these findings by NOAA and
