Do you have any links to further reading on that? This is the first time I've ever heard anything like that. It's pretty alarming.

- Aeolos 11y agoThis 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. [1] http://arstechnica.com/science/2015/11/persian-gulf-temperatures-may-be-at-the-edge-of-human-tolerance-in-30-years/ http://arstechnica.com/science/2015/11/persian-gulf-temperat... 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).

- ssmoot 11y agoThe scientists that published that paper also produced a video to downplay the media's reporting of it: http://www.slate.com/blogs/future_tense/2015/10/27/climate_change_heat_waves_won_t_make_persian_gulf_uninhabitable.html http://www.slate.com/blogs/future_tense/2015/10/27/climate_c... > "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.
- Aeolos 11y agoThat 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.
- grondilu 11y agoAn 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.
- Aeolos 11y ago"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. [1] https://en.wikipedia.org/wiki/Arctic_methane_emissions https://en.wikipedia.org/wiki/Arctic_methane_emissions 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.
