    1. Climate is a primary driver of biological processes, operating fromindividuals to ecosystems, and affects several aspects of human life.Therefore, climates without modern precedents could cause large andpotentially serious impacts on ecological and social systems 1–5 . Forinstance, species whose persistence is shaped by the climate canrespond by shifting their geographical ranges 4–7 , remaining in placeand adapting 5,8 , or becoming extinct 8–11 . Shifts in species distributionsand abundances can increase the risk of extinction 12 , alter communitystructure 3 and disrupt ecological interactions and the functioning ofecosystems. Changing climates could also affect the following: humanwelfare, through changes in the supply of food 13 and water 14,15 ; humanhealth 16, through wider spread of infectious vector-borne diseases 17,18,through heat stress19 and through mental illness20; the economy, throughchanges in goods and services21,22; and national security as a result ofpopulation shifts, heightened competition for natural resources, viol-ent conflict and geopolitical instability23. Although most ecological andsocial systems have the ability to adapt to a changing climate, themagnitude of disruption in both ecosystems and societies will bestrongly determined by the time frames in which the climate will reachunprecedented states1

      As climate departure is projected to occur under all IPCC RCP scenarios, this implies profound changes will take place everywhere on the planet.

      The biosphere will react to this unprecedented shift in equally unprecedented ways. Each species has a comfort zone temperature band to exist within. If the temperature falls outside that zone, it can remain in place and adapt, shift geographical location (migration) or go extinct.

      In an ecosystem, species all depend on each other. When a number of these shift their patterns, it will affect the others, increasing total ecosystem disruptions. Since human activity is dependent on nature, this will also ripple up to humans in a variety of ways.

    1. Although relocations can be difficult, it requires a certain level of privilege to be a climate change migrant in America right now. Most of the people I spoke with are relatively free to move around, without the ties of children or home ownership, and with enough money to afford to relocate.

      There's a racial divide here, too. With harassment and violence on the rise against Black and Asian Americans, moving anywhere where there are fewer of us is another dimension of precarity.
