Strong hypothetical and likely never to happen in our lifetime, but what would Earth be like if the average global temperature reached to 45.3*C. Don't ask me why I picked that precise number, but what would conditions be like and would all life on the planet roast to death or adapt. How hot is too hot? Lastly would it even be possible for Climate Change or Global Warming push temps that far. Has it happened before since the formation of the planet that we can detect?
Location: West Belleville (Approximately 1.5 Miles north, northwest of BTHSW, and .5 Mile east of Kmart)
Highest average global temp that we know of was during the end Permian at about 22-24C (45C would basically be a sterile planet), or about 8-10C hotter than pre-industrial temps (7-9C hotter than today). It wasn't a pleasant place to live if you were a warm-blooded animal. Average temps near the equator were hostile to life, and little in the way of fossils (or coal beds) can be found from that time. Successive waves of extinction occurred over a 6 million year time frame and it took 30 million years for life (and the temperature) to recover. Sea surface temperatures were in the 36-40C range in the tropics during that period based on isotope analysis.
Only if we are foolish enough to burn most of the fossil fuel in the ground will we get temperatures that high. However, it only takes 4-5C worth of warming to transition the climate into a "hothouse" state, with quite unpleasant side effects. With a climate sensitivity of 3C, 750ppm CO2e might do it (current is 480).
Welcome to the shout box. Just trying this feature out.
MakeitRain: The 12z NAM wants to develop a line of storms through the metro around 1-2pm this afternoon. However, the HRRR is not picking up on this piece. I would not rule out the chance of severe weather as we head into the afternoon.

snowday_lover: I was thinking this was to start late tomorrow night...are we thinking earlier? I'm in Ironton, so I'm not holding my breath for much per the maps that have been drawn up. I'm thinking a little bit of sleet and frz drizzle. Is that correct? It's a balmy 18
