earth scientists have concluded that the methods of harnessing energy that have been used over the past two centuries, such as the burning of fossil fuels, are causing climates around the world to change more quickly and suddenly than ever before in human history. evidence includes increased air temperatures, rising sea levels, and the shrinking of glaciers in greenland, alaska, and other regions of earth. the most complex level of organizational hierarchy that climate change could potentially affect is earths\n\nbiosphere.\n\ncommunities.\n\norganisms.\n\npopulations.

Answer

Brief Explanations:

The biosphere is the global sum of all ecosystems and is the most complex level among the options. Climate change affects the entire planet - its living organisms, their interactions, and the physical environment on a large - scale, which is the scope of the biosphere. Communities are groups of different species in an area, organisms are individual living entities, and populations are groups of the same species. They are all at lower levels of the organizational hierarchy compared to the biosphere.
