Long before the dinosaurs, hefty herbivores called pareiasaurs ruled the Earth

Depends on what you mean by "we". Our genus is a few millions years old indeed, but our species is only about 200,000 years old.
our rate of population growth and disregard for sustainable consumption is not gonna work out well for us. i suspect our habits will need to change drastically for humans to make it even another 1,000 years.
Current projections have parts of the planet already uninhabitable before the end of the century (uninhabitable as in "you die even in shade and with plenty of water"). We are messing up our grandchildren's lives.

Edit: as a summary, researchers claim that parts of the Persian Gulf will reach the "threshold temperature" within the next 30 years, hampering human development in these regions. "Threshold temperature" is the temperature where the human cooling mechanisms shut down, i.e. 35C at 100% humidity or 45C at 50% humidity.
Once you reach this temperature, even healthy individuals are at risk of fatal hyperthermia. Note that this doesn't have to be sustained over the whole year - even a few days per year will likely trigger mass-migration. Climate change is likely to be the single most important issue we will have to deal with in the near future (we = human race).
> "Such conditions (the wet-bulb temperature exceeding 35C) would occur only once per decade"
No doubt climate change is an issue, but taking the unique environment of a place that's already pretty brutal to justify such an alarming statement is stretching a bit I think.
And all these are not taking into account the record temperatures in the Arctic circle that are currently being recorded (+4C than last century), which increases the chances of runaway greenhouse effects.
As I said, use google scholar. This is not a conspiracy, these are changes that are happening right now.
The fact that you're so quick in using that expression suggests to me that you either don't know what you're talking about, or you just enjoy scaring people.

Edit: if it's not obvious, "runaway effect" is another term for "positive feedback loop". The first paragraph of the linked article reads:
> Arctic methane release is the release of methane from seas and soils in permafrost regions of the Arctic, due to deglaciation. While a long-term natural process, it may be exacerbated by global warming. This results in a positive feedback effect, as methane is itself a powerful greenhouse gas.
The scale is for 100mm aka 10cm aka 4 inches.
The scale is 27px, the skeleton is 482px from snout to tail, for a suggested size of ~1.8m (5ft10).
I don't know where you live, but you've got pretty fucking huge rabbits if they're the size of an average bloke. Note that this: http://www.oubler.com/assets/userdata/news_media/1433158298.... is not a rabbit
