I've read interesting post couple of days ago about Global Warming on reddit: "Hey guys this research isn't really finding out anything that wasn't already known. RCP 8.5 scenario, which they assumed in their modelling, has long been known to be effectively Armageddon. Any temperature rise past 5.5 degrees is probably irrelevant because there wont be any humans left to deal with that outcome. However it's looking increasingly likely that we aren't on the RCP 8.5 pathway. RCP 8.5 calls for steady continued growth in emissions of around 3%+ per year, which is what we were on in the early part of this decade. The last three years emissions have been effectively flat in spite of ongoing economic growth, and the Paris pledges that will keep warming to about 2.8 degrees call for the emissions peak to be in 2040~ (RCP 4.5). Based on trends in renewables, the downturn in the coal industry, and emissions growth halting, it's increasingly hard to see how we could possibly get back on track to an RCP 8.5 scenario. 2.8 degrees will still be terrible for environment, the economy, and poorer nations of course, and we should really be aiming for the RCP 2.6 scenario, where emissions peak no later than 2020. It's possible emissions have peaked already, but we will need more than three years of data to determine that. Of course, than comes the hard part of taking offline the carbon intensive elements of the world economy (i.e Coal)" source: https://www.reddit.com/r/science/comments/5cz4a7/new_climate_change_estimate_predicts_global/da0sfad/ https://www.reddit.com/r/science/comments/5cz4a7/new_climate...
