Human-Induced Climate Change

The rising temperature of earth’s atmosphere and oceans over the last hundred years has resulted in an uproar of controversy surrounding its environmental and economic concerns. From glaciers slowly melting, to our winters looking more like spring, and our lakes as well as rivers warming, it is obvious us as humans are making our mark and leaving footprints on this earth.  This theory of increasing global temperature is not a new conjecture and has been a concern to many. Many studies show the affects of global warming due to the rising concentration of greenhouse gas emissions but thanks to NASA, a study has shown just what we really are impacting. Cynthia Rosenzweig led the study to show how humans are contributing to climate change and how we are impacting the Earth’s natural ecological systems.  The study linked physical and biological impacts since 1970 with increasing temperatures during this time period within North America, Europe and Asia.

It is logical for our world to be concerned of an environmental crisis that could lead to a slow termination of our planet, but it is also rational to ask the question what’s the worst we might have done? In over 80 conclusive studies that include at least 20 years of records and statistics, the observed changes to our physical systems include glaciers melting, permafrost disappearing and the temperatures of lakes and rivers warming. In our biological systems, flowers and leaves are blooming earlier during the spring, species of birds are arriving earlier from migration periods, and vegetation and animals are spreading closer towards the poles. In our oceans, lakes and rivers; fish and plankton are adapting from cold temperature environments to warmer environments.

The study concluded that after comparing global-scale temperatures to those observed impacted areas of warming, that these impacts are certainly connected and due to human-induced actions.

“Humans are influencing climate through increasing greenhouse gas emissions and the warming is causing impacts on physical and biological systems that are now attributable at the global scale and in North America, Europe, and Asia,” said Rosenzweig.

Climate change is an ever-growing dispute of concerns and struggles, but it is evident that we as humans are factors contributing to this problem. Although this is the concern, it is also apparent that we have the power to change what is occurring. These changes would be large, and take a great deal of dedication and would have to occur as a whole for improvements to be accomplished. Starting with little changes by individuals such as reducing our carbon output in various ways, improvements can be made. Although it is apparent that we are unable to reverse increasing climate change, we do have the power to slow its inevitable process.
