Changes in the climate are caused by an imbalance between the amount of radiation entering and leaving the atmosphere. The pace at which the planet is warming due to climate change is different from that of previous warming periods. Temperatures throughout the world might climb by as much as 5.4 degrees Celsius by the year 2100. Changes in solar activity and volcanic eruptions have played smaller roles than human activities in driving climate change during the last century. The human activity of massively changing natural systems over the past several decades has led to a net increase in atmospheric carbon dioxide levels. There is widespread agreement that climate change poses a major risk to ecosystems, biodiversity, and human health. Changes in the Earth's physical environment are linked to this phenomenon, which has far-reaching consequences for all forms of life on the planet. Challenges facing society today include adapting to the effects of climate change and working to stop its worsening. It is essential for policymakers to apply individualised policies, particularly for at-risk groups.
