For a helpful reference: the IPCC AR 5 "summary for policymakers", aka the bulletpoints, aka the TL;DR of the full IPCC AR 5 report:

http://report.mitigation2014.org/spm/ipcc_wg3_ar5_summary-for-policymakers.pdf

"Without additional efforts to reduce GHG emissions beyond those in place today, emissions growth is expected to persist driven by growth in global population and economic activities.Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 °C to 4.8 °C compared to pre-industrial levels10 (range based on median climate response; the range is 2.5 °C to 7.8 °C when including climate uncertainty, see Table SPM.1)11 (high confidence). The emission scenarios collected for this assessment represent full radiative forcing including GHGs, tropospheric ozone, aerosols and albedo change. Baseline scenarios (scenarios without explicit additional efforts to constrain emissions) exceed 450 parts per million (ppm) CO2eq by 2030 and reach CO2eq concentration levels between 750 and more than 1300 ppm CO2eq by 2100. This is similar to the range in atmospheric concentration levels between the RCP 6.0 and RCP 8.5 pathways in 2100.12 For comparison, the CO2eq concentration in 2011 is estimated to be 430 ppm (uncertainty range 340–520 ppm).13 [6.3, Box TS.6; WGI Figure SPM.5, WGI 8.5, WGI 12.3]"

"Delaying mitigation efforts beyond those in place today through 2030 is estimated to substantially increase the difficulty of the transition to low longer-term emissions levels and narrow the range of options consis- tent with maintaining temperature change below 2 °C relative to pre-industrial levels (high confidence)."

"Decarbonizing (i.e. reducing the carbon intensity of) electricity generation is a key component of cost- effective mitigation strategies in achieving low-stabilization levels (430–530 ppm CO2eq); in most integrated modelling scenarios, decarbonization happens more rapidly in electricity generation than in the industry, buildings, and transport sectors (medium evidence, high agreement)"
