Causes

Societies have become increasingly dependent on nonrenewable sources of energy [fossil fuels].

Long term use of nonrenewable energy will change the climate [unsustainable].

Effects

Climate change is here.

The climate change affects the weather, the biosphere [ecosystem shifts, flora and fauna], and the hydrosphere [shifts from polar ice caps and glaciers to surface water and groundwater].

Solution

Conserve nonrenewable energy.

Research and develop new types and sources of renewable energy.
