Changes in the distributions and abundances of individual species One of the major concerns about the effects of global warming during the next century is the adverse effect it will have on nature—the retreat of many of the Earth’s forests because of climate stress, warming, and drought; the disappearance of delicate wetland areas due to increasing rates of sea-level rise; and the disappearance of many types 23  Changing ECosystEms of vegetation (trees and plants) that humans have become dependent on (such as sugar maples in New England), which may be gone by the end of the century under continued warming trends.

Some plants are currently growing in areas where they could not before because rising temperatures have provided greater amounts of heat, sunlight, and water. , columbines, wild geraniums) are blooming earlier than before. Edith’s checkerspot butterflies are not migrating northward. Global warming threatens the existence of currently endangered plant and animal species and puts others at risk as CO2 levels rise. Global warming alters temperatures, humidity, soil, and vegetation; endangers natural habitat range; and can negatively affect other species in the ecosystem that endangered species depend upon for food.

He stated, “We’re going to be at 400 ppm in 10 years’ time. ’ ” Ecosystems, Adaptation, and Extinction The report does conclude, however, that there are technological options available to reduce CO2 emissions that will need to be used. The study also concluded that the biggest obstacles involved with using these new technologies, along with renewable resources of energy and “clean coal,” are the current economic investments and traditionally strong bond to the oil industry, cultural attitudes that oppose change, and simple lack of awareness by many people.
