and we've only existed on an industrialized, environment-affecting scale for a few hundred years.
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.
This is the first relevant article I read [1]. I've since gone through google scholar and there is lots of relevant research. "Alarming" doesn't begin to cover it.
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.
That is not the only report. There appears to be a consensus that this will happen at the latest by 2100. This report claimed only 30 years.
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.
An expression like "runaway greenhouse effect" is normally only used to describe what happened on planets like Venus. IIRC on Earth there is a consensus about something like that to have "virtually no chance" of being induced by anthropogenic activities.
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.
"Runaway greenhouse effect" is what could happen if the methane deposits in the Arctic Siberian tundra are released to the atmosphere. See [1] for more information.
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.
