Final answer:
Global warming, caused by human activities intensifying the greenhouse effect, is projected to have significant worldwide environmental impacts in this century. Some concrete examples of specific environmental consequences of global warming include the retreat of glaciers, weather extremes, desert expansion, habitat shifts, biodiversity loss, changes in food production, rising sea levels, human displacements, and increased violence.
Step-by-step explanation:
Global warming, caused by human activities intensifying the greenhouse effect, is projected to have significant worldwide environmental impacts in this century. Some concrete examples of specific environmental consequences of global warming include the continued retreat of glaciers, greater weather extremes, expansion of deserts, shifts in natural habitats, loss of biodiversity, changes in food production, rising sea levels, displacements of human populations, and increases in human violence. To lessen the threat, we need to transition away from fossil fuels towards cleaner sources of energy.
