The New Jersey legislature passed a bill requiring the NJDEP to create regulations to bring emissions down 80% below 2006 levels by 2050, strengthening the 2007 Global Warming Response Act. (rutgers.edu)
Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels (SR15). (ipcc.ch)

What humanity chooses to do (or not do) in the next year or two-and over this decade-to lower greenhouse gas (carbon) emissions will determine how catastrophic things will get in the future and how quickly. (thegreenspotlight.com)
