SoylentNews
Bridging the gap between left and right. I came across this clip showing Glenn Beck and Samantha Bee, and thought that this SoylentNews story / comment thread should be stickied till the new year so we have an ongoing conversation. It's a short clip from her show where Glenn Beck is a willing guest; the key point is they are trying to find common ground. Beck points out that Bee is following some of his own patterns of crying "catastrophe" but they really don't provide much insight beyond the significance of their little coming together moment.
The divide is clear and present on this site as most everywhere else, I would like to see a meta discussion where we fact check each other and drill down through the rhetoric until we get some straightforward lists and proposals on how we can move forward together. What are the fundamental blockers? Which ideas do we consider to be too outrageous for credibility? Many here are guilty of attacking each other — can we try and Spock it out for about a week?
I'll start us off with my supposition:
Climate change is real and human activity has an important effect on it. We must agree on this point in order to move forward, and social/economic issues must be handled after needed environmental changes."
If you post as AC — try and behave as if you were logged in — reduce the flames for better quality discussion.

+5C Is not 5C hotter summers. It's more like +10C over land (varies by location)
Which land locations. The problem here is that most current warming is in areas that are traditionally cold. The reason is that the snow cover is melting. So you see most such warming at higher latitudes such as above 45 degrees and during the winter when melting snow cover can actually happen and have the warming effect from the radical change in albedo.
So no, it's not 45 C heat waves in New York.

This will be buried, but anyways:
New York already saw 37C heatwaves this century, two in 2011 hit 39C, with a 42.2C all-time record reading at one station.
The US Northeast region is projected to be 6-8C warmer under higher emission models in RCP8.5.
The global models don't include Urban Heat Island strengths for individual cities, which for NYC is around 2.5C nowadays (+1-2C summer daytime, +5-6C nighttime).
Adding it all up, in a disastrous-for-all +5C global average temp increase world NYC could see 44-47C heatwaves.
Sources: IPCC AR5, Gaffin et al 2008, Fu Gao Drake et al 2012, Rosenzweig and Solecki 2010, Meir Orton Pullen 2013, USGCRP; etc.
I am NOT a climate scientist though.

Or might not, since that 5C increase would not be universally distributed, but rather heavily weighted towards the poles. Those hotter temperatures would also come with significantly increased radiation to space.
Further, despite assertions to the contrary those global models may well include a fair bit of urban heat islands. The statistical complexity behind adjustments of these temperature measurements can hide a lot of manipulation.

You are right. That's the reason for the 6-8C figure for NY in the previous post.
Oh, it's not an assertion. Global climate models do not correct for Urban Heat Islands. Even the latest ones use grid cells that are ~180x180km (110x110 miles) on average. IPCC AR5 chapter 8 deals with additional effects on urban environments.
There are projections for a few individual cities that include these effects. The climate models used are different and run on for example 1x1km grids.
While true, trust issues?

These models are based on data which does correct for urban heat islands. And cell size is irrelevant.

Yes.
