Likely impacts include large - scale disintegration of the Greenland and West Antarctic ice - sheet; the extinction of an estimated 15 — 40 per cent of plant and animal species; dangerous ocean acidification; increasing methane release; substantial soil and ocean carbon - cycle feedbacks; and widespread drought and desertification in Africa, Australia, Mediterranean Europe, and the western USA.

A new paper that combines paleoclimatology data for the last 56 million years with molecular genetic evidence concludes there were no biological extinctions [of Arctic marine animals] over the last 1.5 M years despite profound Arctic sea ice changes that included ice - free summers: polar bears, seals, walrus and other species successfully adapted to habitat changes that exceeded those predicted by USGS and US Fish and Wildlife polar bear biologists over the next 100 years.

Other ecological crises of great importance are not, however, dealt with here: species extinction (and loss of biological diversity in general), deforestation, desertification, soil degradation, acid rain, the proliferation of toxic wastes (including in living tissues), market - regulated biotechnology, urban congestion, population growth, and animal rights.

This new report, according to the New York Times, will assert that expected warming in this century will lead to wide - spread melting of land ice, extreme heat waves, difficulty growing food and massive changes in plant and animal life, probably including a wave of extinctions.

But other elements could potentially also contribute to a collapse: an accelerating extinction of animal and plant populations and species, which could lead to a loss of ecosystem services essential for human survival; land degradation and land - use change; a pole - to - pole spread of toxic compounds; ocean acidification and eutrophication (dead zones); worsening of some aspects of the epidemiological environment (factors that make human populations susceptible to infectious diseases); depletion of increasingly scarce resources [6,7], including especially groundwater, which is being overexploited in many key agricultural areas [8]; and resource wars [9].
