Orwig reported that a warmer New England climate would put native habitats and wildlife at increasing risk and force many species to migrate north in order to survive – something trees can do over time, but not necessarily quick enough for forest ecosystems to remain healthy.
Orwig iniulat na isang pampainit New England klima ay ilagay ang mga katutubong yaman at hayop sa pagtaas ng panganib at lakas ng maraming uri ng hayop-migrate hilaga upang manatili - isang bagay na puno ay maaaring gawin sa paglipas ng panahon, ngunit hindi kinakailangan ng mabilis na sapat para sa forest ecosystem upang manatiling malusog.
