In particular, these models love a technology called «bioenergy carbon capture and sequestration (BECCS)» because it has negative emissions — you grow biomass, harvest it and burn it for electricity, and then store the pollution underground.

Our results show that the only way in our scenarios to achieve the 1.5 °C target in the presence of SIAF would be through negative emissions, which imply more risks and uncertainties for the future [Rogelj et al., 2015; Hansen et al., 2016].

The tricky bits as I see it are: issues of glare for passersby / neighbors; working out what hours to deploy it on my roof (or may be to shade my lawn in the middle of a summerâ s day, etc); I would have to work out sun elevations, hours of sunlight in my area, etc to determine how much visible light should be reflected; and then finally express this as a negative forcing in W / metre2 to be offset against my presumed calculated positive forcing due to my familyâ s emissions of GHG, etc..

As I set out in UVJan18 @ 4, and you also @ 7, the need for emissions - cuts and for negative - emissions are inexorably mixed.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).
